dotnet test coverage

To use Coverlet for code coverage, an existing unit test project must have the appropriate package dependencies, or alternatively rely on .NET global tooling and the corresponding coverlet.console NuGet package. If true, starts dotnet watch test after test discovery is completed. And Test Explorer gives you a visual explorer panel when you can run tests: all of them, a group in context or individual test. Now that you're able to collect data from unit test runs, you can generate reports using ReportGenerator. This script test the second test project called StrikesRepository.Test You need to specify the report which is specified the last one. Unfortunately, in this case, you won’t get an aggregated summary of tests results, instead, you will get a summary per test project. Examples below are based on GitHub SampleDotNetCore2RestStub repository. Using them outside of the project won’t work because the command cannot be found - you may have seen this with ReportGenerator if you tried to run it from outside the Test project’s directory. If you intend to run tests for the full .Net Framework, you have to install the right SDKs for that. To add Coverlet to your test project use the following command. The XML file contains the results. This is so that the test projects have access to the PrimeService for testing. Enable the debug information. From your console run the following (from your test project’s directory): This command assumes that you’ve got your coverage data store in the sub-directory TestResults, and that you’ve got a coverage.cobertura.xml file (you will if you’ve been following along). For .NET Core, the Opencover can invoke the dotnet directly to get the coverage results instead of calling runners of the unit test framework; Summary of Steps. There’s a separate command for getting coverage in .NET Core projects: cover-dotnet or just dotnet. Copy the snippet below and replace the contents of the Class1.cs file that was automatically created in the Numbers directory. code coverage, dotnet, dotnetcore After some research, I found out that two free tools that combined can generate code coverage reports. dotnet test /p:CollectCoverage =true This command will run your unit tests, and collect the coverage metrics which get stored in the current working directory in a new file “coverage.json”. Luckily dotnet CLI have another command for running tests – namely dotnet vstest.In this case, we do not operate on projects but we provide a location for assemblies with tests. It integrates with the dotnet test infrastructure built into the .NET Core CLI and when enabled, will automatically generate coverage results after tests are run. Rename the UnitTest1.cs files to PrimeServiceTests.cs. If you’re interested in other tools that are available here’s a good list of some Global Tools. Unit tests help to ensure functionality, and provide a means of verification for refactoring efforts. With Azure DevOps you need to do this step yourself, meaning that apart from generating the test results with the unit tests step (dotnet test) you need to generate the code coverage report (HTML) manually in … That means we can just "dotnet test" and it'll build and run tests. It's a very simple app): I'm guessing that a similar approach for code coverage can be attained. JetBrains dotCover is a.NET unit test runner and code coverage tool that integrates with Visual Studio and JetBrains Rider. Below is the example coverage.cobertura.xml file. In the column 'Line', we get the percentage of lines checked after running the tests and it's the same for … For manual test sessions, dotCover shows what parts of code were called during the session and which parts were not reached. Code Coverage in .NET Core is tricky if you want to use it in a CI build and/or SonarQube. The output from running Coverlet as a Global Tool is more or less the same as the per-project tool’s output, so I’ll skip including it here. dotnet-test-explorer.autoWatch. > dotnet test /p:CollectCoverage=true Add Coverlet to the test projects. With SonarCloud you only need to publish test results and it will do the reporting for you. Using the coverage analysis data, you can easily get to the source code of the tested application. And Test Explorer gives you a visual explorer panel when you can run tests: all of them, a group in context or individual test. Adda reference to web application project and write some unit testsif you start with a new test project. 2020 I’ll show you how to use it both ways in this post. This post is about Measuring code coverage of .NET Core applications with Visual Studio. To enable code coverage, you need to run the dotnet test command with CollectCoverage property with value true. If you’d like to, read more about ReportGenerator on the project’s GitHub. The previous example showed you how to quickly get some metrics from your tests. Coverlet is part of the .NET foundation. Examples use code from .NET Core integration testing and mock dependencies post. If the metrics that were written out to the console in the previous step weren’t enough for you then read on because the reporting is about to get A LOT better! From the command prompt, change directories to the XUnit.Coverlet.MSBuild project, and run the dotnet test command: The resulting coverage.cobertura.xml file is output. I will use two different Global Tools to produce some code coverage reports similar to how we did earlier in the post. Test data is transformed to the Cobertura format by Coverlet — a cross platform code coverage library for .NET Core. open source project on GitHub - ReportGenerator. I mentioned Coverlet at the start of this article, you’re probably wondering what it is? This NuGet package integrates coverlet with the .NET build system, so that coverlet will compute code coverage after tests. Use dotnet.exe to run coverage analysis of .NET Core unit tests. Last week I blogged about "dotnet outdated," an essential .NET Core "global tool" that helps you find out what NuGet package reference you need to update..NET Core Global Tools are really taking off right now. From a command prompt in a new directory named UnitTestingCodeCoverage, create a new .NET standard class library using the dotnet new classlib command: The snippet below defines a simple PrimeService class that provides functionality to check if a number is prime. So I’m vesting more time learning tools and processes around Microsoft tools. just use attribute "[ExcludeFromCodeCoverage]" either class or method level. For more information, see namespace (C# Reference). Find the current & past versions of ReportGenerator here. In common practice, automated unit tests are what exercise the program so that the code coverage tool can perform its measurements. My requirements were: Runs on Linux and WindowsDisplays a… I blogged about .NET Core, SonarQube and Code Coverage - but this felt like a hack. In the test task you have to add –collect:”Code Coverage” for the task to add a logger for code coverage. after that, we can use easily the integration between MSBuild and coverlet to run the test and measure the coverage with the following command: dotnet test /p:CollectCoverage=true. For .NET Core projects, the Console Runner provides a separate cover-dotnet command (or a shorter version dotnet).It runs dotnet.exe under coverage analysis (as if you specified the path to dotnet in --TargetExecutable). Good news, you can supply more parameters to dotnet test to specify such things! Moreover your project can also has many (or not) tests. dotnet add package coverlet.msbuild And because it integrates directly with dotnet test there is no other work to do. Just run dotnet test and pass the parameter /p:CollectCoverage=true to enable the output. Unit test coverage and continuous testing. > dotnet add package coverlet.msbuild If you’d like to, read more about Coverlet on the project’s GitHub. Examples below are based on GitHub SampleDotNetCore2RestStub repository. dotCover calculates and reports statement-level code coverage in applications targeting.NET Framework,.NET Core, Mono, or Mono for Unity. The report generation is possible using another open source project on GitHub - ReportGenerator. Added coverlet, which integrates with MSBuild and automatically runs when you "dotnet test" if you "dotnet test /p:CollectCoverage=true" (I think this should command line switch should be more like --coverage" but there may be an MSBuild limitation here.) This is a pretty high level overview of some of the options you can supply to Coverlet, if you want to get more details on what is possible, check out the Coverlet documentation. Getting started. One last parameter that comes in handy is /p:Exclude. These files are not very convenient to read. One word of warning, DO NOT use dotnet add package... to install ReportGenerator, this will not allow it to work as a tool on the CLI. Last week I blogged about "dotnet outdated," an essential .NET Core "global tool" that helps you find out what NuGet package reference you need to update..NET Core Global Tools are really taking off right now. Those lcov files look like this, showing file names, file numbers, coverage, and number of exceptions. Then lines 25–29 publish the report to coveralls.io using the Coveralls GitHub Action. Also, when trying to improve coverage, one may want to keep generating the report after every test written. Those are integration tests because they test more than one application module at a time, but they are run with a unit testing … Convert Code Coverage Files. Coverlet collects Cobertura coverage test run data, which is used for report generation. Open both of the UnitTest1.cs files, and replace their contents with the following snippet. To understand what places in your code are covered and what not, you might want to gather coverage code coverage statistic for your tests. This allows us to filter out code that we don’t want included in code coverage metrics. ReportGenerator can then take those XML outputs as an input and generate you a single XML code coverage result for the entire project.  •  dotnet test /p:CollectCoverage = true /p:CoverletOutputFormat = cobertura. Likewise if you think you may want to run code coverage on a build server, you probably want to go with the packages installed via your .csproj file. Note the Global Tool method doesn’t require adding the coverlet.msbuild nuget package to the project. They are meant for devs - this isn't a replacement for chocolatey or apt-get - this is more like npm's global developer tools. This is the tricky part. Before you can use the Coverlet Global Tool, you must install it. When that was done, it then changed directories, stepping up one level. If all tests are successful, the test runner returns 0 as an exit code; otherwise if any test fails, it returns 1. Finally, as promised here is a small sample project where I’ve set up the a sample API, and sample API test project to demonstrate what was mentioned here in this blog post. The first tool is called Coverlet which generates the code coverage as I wanted and it’s also working with .NET Framework. Build the entire solution. This blog post expects that there is .NET or ASP.NET Core project with unit tests and code coverage reports. /p:MergeWith=....\coverage.cobertura.xml will merge the report and write it under the target test directory as coverage.cobertura.xml as well A program with high test coverage, measured as a percentage, has had more of its source code executed during testing which suggests it has a lower … Here’s a sample of what that command looks like: This command is generating coverage metrics based on the “SampleApi.dll”. The other two parameters specify the target directory for the results to be stored, and the report type format - HTML. Execute the Coverage.bat file. XunitXml.TestLogger Note: In the project file, we need a tool reference to ru… It supports multiple coverage formats, like json (default),Icov, opencover, cobertura. When you run the command you’ll see something like this: In the command above we’re specifying to use the cobertura format with the /p:CoverletOutputFormat=cobertura parameter, and the /p:CoverletOutput="./TestResults/ tells dotnet test & Coverlet to store the resulting metrics in a folder called “TestResults”. Until recently getting code coverage metrics for your .NET Core projects had required using Visual Studio or a 3rd party paid tool. You don’t have to use Xunit for this, but it’s the testing framework I like, and it isn’t always as well documented for this kind of thing so it is the tool I’m using. First get dotnet test to output a trx file with the test results by passing the arguments -l trx. With coverage data I also output unit test results in Microsoft and xUnit formats to UnitTests folder. If you look at the coverage.json file it likely won’t make any sense, don’t worry we’ll do something with it in a bit. Below is the example coverage.cobertura.xml file. To do this, you must choose your criteria and minimum threshold. Manual test sessions. If you write more code and do not write a unit test then code coverage will be decreased; if you write a unit test then code coverage will be increased. This name is required but is case insensitive. Coverlet is a code coverage framework for .NET, with support for line, branch and method coverage. Although Microsoft offers a solution to calculate natively the code coverage, it generates several problems: difference in results between the Build Server and “Visual Studio / Test / Analyze Code coverage”, code coverage problem with referenced assemblies, etc. However, let it be enough to say that the unit test… If you will want to run code coverage on your local dev across many projects you may want to install the global tools. If you’re interested in a way to set up your local system so that you don’t need to worry about installing more dependencies or where you’re at in the file system in relation to the test project, read on to find out how to set up Coverlet and ReportGenerator as Global Tools. First, we calculate the test coverage and output a coverage.coverlet.xml file. We also need some NuGet packages to make things work: 1. coverlet.msbuild 2. Once the build is green, I am able to see code coverage tab but it still does not show html report. Those are integration tests because they test more than one application module at a time, but they are run with a unit testing … Read on and I’ll explain how and provide link a sample project at the end of this post. Additionally, this article details how to use the code coverage information collected from a Coverlet test run to generate a report. Line 21: install the report generator tool for coverage reports; Line 24: run "dotnet test" to invoke the test. Tip: If you're having trouble with the xUnit test runner, make sure to have at least version 1.0.0-rc2-build10025 of the dotnet-test-xunit package referenced. Rename the Class1.cs file to PrimeService.cs. Cobertura is popular code coverage utility in Java world. Use dotcover cover coverage.xml to run the coverage with the specified parameters.. Install Nuget packages. Overall it looks pretty similar to what we were doing before, except now we supply the path to the SampleApi.dll. Here are the options I used: And you will get your results (P.S. It only imports pre-generated reports. So, there was no choice “Mac or Linux or Windows”. This is a cross platform option that relies on the .NET Core CLI, and it is great for build systems where MSBuild is not available. Added coverlet, ... Coverage Gutters that can read in lcov files and others and highlight line gutters with red, yellow, green to show test coverage. Global Tools are essentially cross-platform console tools that you can create and distribute with .NET Core & Nuget. dotnet test. Also, we need to add –collect:”Code Coverage” to add a logger for code coverage as shown: Convert Code Coverage Files. This article discusses the usage of code coverage for unit testing with Coverlet and report generation using ReportGenerator. It is common to require developers to achieve code coverage of at least 80%. If you only care about running code coverage for a single project, you probably want to go the “per-project tool” route (adding the nuget package / CLI Tool Reference). I did a little more research and found a better way. get familiar the CLI .net commands. For the purpose of this article, you'll create a class library that will be the system under test, and two corresponding unit test projects. Below you'll find language- and tool-specific analysis parameters for importing coverage and execution reports. The –collect parameter instructs dotnet test to create code coverage files with Coverlet. The concept of “.NET Core Global Tools” was introduced in .NET Core 2.1 as a feature of the .NET Core CLI. Well done! Examples use code from .NET Core integration testing and mock dependencies post. To get started, we need a test project and some NuGet packages. The test task added above only generates .coverage files for each test project. Add this package dependency by running the dotnet add package command: The previous command changed directories effectively scoping to the MSBuild test project, then added the NuGet package. In … If there is any difficult-to-test code, for example, network, database, unit test, class, or method etc. ReportGenerator converts coverage reports generated by Cobertura among many others, into human readable reports in various formats. Code coverage tools measure how completely a program runs as it is running.The trick is to run the software while the code coverage tool is monitoring the program. As an alternative, you could use the MSBuild package if your build system already makes use of MSBuild. ReportGenerator is another tool I briefly mentioned, it generates easy-to-read coverage reports in various formats. you will get the following result: In the first column from left to right we can see the list of modules covered. Then follow it up with the Publish Test Results task. I love working with .NET Core on the command line (CLI) and Visual Studio Code. To add ReportGenerator as a tool, you will need to manually add this code to your test project file: Before you go on, do a quick check of the version number, you likely want the latest version number if you have no reason to use a lower one. If you’re like me you probably were left with questions like how to I specify where to store the output, how to I generate the metrics in another format, and so on. The "system under test" refers to the code that you're writing unit tests against, this could be an object, service, or anything else that exposes testable functionality. Additional arguments that are added to the dotnet test … Unit test coverage and continuous testing. Filtering can be applied by namespace, assembly, and more in this manner /p:Exclude=[Assembly-Filter]Type-Filter. Interested? As part of the dotnet test run, a resulting coverage.cobertura.xml file is output to the TestResults directory. Thus, we need to install the coverlet.msbuild package in order to generate coverage reports in the CI pipeline. Once you’ve installed Coverlet, you can now run the command to generate the coverage metrics. Had the same issue and in my case the problem was that the package reference "coverlet.msbuild" was not properly added by Visual Studio to the *.csproj file. Making it cross platform is on the radar, and may even be supported by the time you read this. After running this command, an HTML file represents the generated report. That means we can just "dotnet test" and it'll build and run tests. Unit Testing Framework Setting up the ReportGenerator Global Tool is just as straightforward as setting up the Coverlet Global Tool was. The test task only generates .coverage files for each test project. Azure DevOps. So, there was no choice “Mac or Linux or Windows”. Let's generate a cool UI using ReportGenerator. With the introduction of Coverlet you can now generate code coverage metrics on the command line, and the further process the collected data into reports using Report Generator. The first step was to get the ‘dotnet test’ build step to collect the code coverage, and not just dump TRX files. They are meant for devs - this isn't a replacement for chocolatey or apt-get - this is more like npm's global developer tools. Essentially, you need to ensure that the test projects are run under dotnet test with a different output XML file to the same folder. In .net core 2.1, these can be installed globally (similar to npm install -g). For this post I’ll assume you’re already familiar with unit testing and XUnit, if you’re not read up on that first and come back to this post when you’re ready to find some test coverage metrics. From the command prompt, use the dotnet add command: The MSBuild project is named appropriately, as it will depend on the coverlet.msbuild NuGet package. To do this, go to the “Arguments” field of the dotnet test build step and append --collect "Code Coverage", as well as ensuring that “Publish test results and code coverage” is enabled. dotnet test got an additional parameter: --collect:"XPlat Code Coverage" Coverlet is a tool which gives you the option to create code coverage files in multiple formats and isn’t dependent on the OS. For more other parameters, see Analysis Parameters. Well, this test would cause the runtime to test the conditional and then to execute the return x/y statement, thus executing two-thirds of the method. The Tooling for .NET Core in Visual Studio 2015 is preview 2 and code coverage does not work so far. (Alexey Totin) […] Poor at english says: ... All our dotNet tools (dotCover, dotTrace, and dotMemory) use a common profiling core that was initially developed only for Windows. The xunit, xunit.runner.visualstudio and Microsoft.NET.Tests.Sdk packages are required for xUnit, while the dotnet-xunit CLI tool allows us to run tests directly with dotnet xunit and supply xUnit parameters instead of going through dotnet test. dotnet-test-explorer.testArguments. SonarQube doesn't run your tests or generate reports. You can do it directly with the general Microsoft driver: dotnet.exe. Your own computer, AppVeyor, Azure DevOps and i'm assuming GitHub Actions. We’re still excluding the Xunit code as we don’t need to include that in our metrics, we then output the results to the “coverage-reports” folder. Configure test task. I found just installing Visual Studio 2017 with all the .Net SDKs quite simple for that. Now in Rider! Coverage Gutter display coverage result with colors in your screen and you can activate or deactivate it. This article is based on the sample source code project, available on samples browser. Test project can be a regular .NET Core library project. Test coverage is a measure used to describe the degree to which the source code of a program is executed when a particular test suite runs. Let’s say this was the only method in our codebase. The action requires a line to pass in the GITHUB_TOKEN, which is available in … We’ve implemented what we already had. Running the above command will produce the following: Per-project tools are pretty useful, and great for build servers. Post summary: Examples how to measure code coverage of .NET Core unit tests with OpenCover. To add the nuget package to your project run the following command - dotnet add package coverlet.msbuild from the cosole and you should be all set. e.g. This allows for System.Math to be accessible without a using System; namespace declaration. I am using dot test to generate the .coverage file and then using CodeCoverage.exe to convert it to xml. One more important thing: the updated runner doesn’t require any additional workarounds for getting coverage of long-running tests (> 100 ms). To analyze the test cases, add task for Dotnet Core and configure it to run Test Commands. Build the solution using the dotnet build command: If the build is successful, you've created the three projects, appropriately referenced projects and packages, and updated the source code correctly. Tony Ranieri If you’re curious my example project uses v2.6.3. The xUnit test project template already integrates with coverlet.collector by default. For example, we want to get coverage of tests in some project. But SonarQube needs a .coveragexml and does not understand the .coverage file format. Details here. So if you’re interested in the code coverage of your project, but don’t want to commit to the package, this isn’t a bad way to go. dotnet test /p:AltCover=true In the default operation it will produce OpenCover format output in a file coverage.xml (or in the case of multiple target frameworks, and from release 4.0.600, files of the form coverage.$(TargetFramework).xml for each such target) in your project directory. Microsoft.NET.Test.Sdk 4. I hope now it is clear what code coverage is and how to control it. In the workflow above, lines 21–24 generate a coverage report using dotnet test and coverlet. As an example, if you have a simple application with only two conditional branches of code (branch a, and branch b), a unit test that verifies conditional branch a will report branch code coverage of 50%. If you want to run your tests get metrics on it as easily as possible, here’s the command you want to run: This command will run your unit tests, and collect the coverage metrics which get stored in the current working directory in a new file “coverage.json”. The following procedure has the advantage of being simple and easily verifiable locally. code coverage can work on any build system which has dotnet core SDK installed. Why? This post is a kind of recipe to get started into .NET Core 3.1 with coverage and SonarQube to keep track of metrics. Once this conversion is done, I am using reportgenerator to use this xml and generate report in a coverageresult folder. dotnet-testx is a dotnet tool that handles the following for you: There are two types of code coverage tools: In this section, the focus is on data collector tools. That can be done by going to your command line (I prefer Powershell) and running: After installing Coverlet, you can run dotnet tool list -g and verify it was installed, as well as view any other Global Tools you may already have installed. Enabling code coverage is as simple as setting the CollectCoverage property to true. The test runner executes the tests defined for a unit test framework (for example, MSTest, NUnit, or xUnit) and reports the success or failure of each test. The subject of automated unit testing is a bigger topicthan I can do justice in this blog. To use coverlet and extract code coverage, this line does the trick: Post summary: Examples how to measure code coverage of .NET Core unit tests with OpenCover. coverlet can be installed as a dotnet tool with dotnet tool install --global coverlet.console to make it globally available, providing it's own CLI tool running directly at … I specify the results directory which I'll copy out later and specify a trx logger to get a VSTest results file. Basic scenario for .NET Core. Make sure you know to what extent your code is covered with unit tests. However, they are only available in the context of the project that adds them as a reference. Using Xunit to unit test your .NET Core code is no different than unit testing your .NET Framework code. Open this file to explore the coverage results in your web browser. The dotnet cli has an extension mechanism that allows one to write custom commands. Line 02 shuts down any remaining background build services, just in case any keep a lock on the .sonarqube directory. Also it expects the existence of Azure DevOps build pipeline that is connected to source code repository. Tip: If you're having trouble with the xUnit test runner, make sure to have at least version 1.0.0-rc2-build10025 of the dotnet-test-xunit package referenced.
