Use Assert.Throws on code where exception expected: [Fact] public void TestMethod1_Error_twoMathces() { var message = “some text”; var parser = new MessageTypeParser(); Assert.Throws<MessageTypeParserException>(() => parser.GetType(message)); }
Jimmy Bogard solved this with a nice RunnableInDebugOnlyAttribute. See this blog post: Run tests explicitly in xUnit.net public class RunnableInDebugOnlyAttribute : FactAttribute { public RunnableInDebugOnlyAttribute() { if (!Debugger.IsAttached) { Skip = “Only running in interactive mode.”; } } }
You can also add it with json. In the root directory of your test project add a file called “xunit.runner.json”. Right-click the file, properties. Select “Copy if newer” for copy to Output directory. Then in the file enter this json: { “methodDisplay”: “method” } Note that you may1 require to restart the IDE in order … Read more
You can click “Cancel” in Test Explorer: Show Test Explorer by going to TEST > Windows > Test Explorer. This is in Visual Studio 2013. Instructions for other versions of VS can be found here
I spent a lot of time trying to figure this one out in my project. This related Github discussion from @NPadrutt himself helped a lot, but it was still confusing. The tl;dr is this: [MemberInfo] will report a single group test unless the provided objects for each test can be completely serialized and deserialized by … Read more
In xUnit 2.* this can be achieved using the TestCaseOrderer attribute to designate an ordering strategy, which can be used to reference an attribute that is annotated on each test to denote an order. For example: Ordering Strategy [assembly: CollectionBehavior(DisableTestParallelization = true)] public class PriorityOrderer : ITestCaseOrderer { public IEnumerable<TTestCase> OrderTestCases<TTestCase>(IEnumerable<TTestCase> testCases) where TTestCase : … Read more
The GetEnvironmentVariable works fine in xUnit tests. The problem is to properly set a variable. If you set the variable at Properties -> Debug page, then the variable is written to Properties\launchSettings.json and Visual Studio makes all work to launch an application with the selected profile. As you could see, launchSettings.json even isn’t copied to … Read more
Use params before the method’s string[] argument, and then you won’t need to initialize a string[] in InlineData attribute, rather you could use a variable number of string literals, for which the compiler doesn’t complain one bit: [Theory] [InlineData(“2000-01-02”, “2000-02-01”)] public void TestSynchronizeMissionStaffing_PeriodNoMatch(params string[] dateStrings)
xUnit has an IAsyncLifetime interface for async setup/teardown. The methods you need to implement are Task InitializeAsync() and Task DisposeAsync(). InitializeAsync is called immediately after the class has been created, before it is used. DisposeAsync is called just before IDisposable.Dispose if the class also implements IDisposable. e.g. public class MyTestFixture : IAsyncLifetime { private string … Read more
There is a much easier way to run all tests: Install the .NET Core Test Explorer extension Open a .NET Core test project in VS Code, or set dotnet-test-explorer.testProjectPath to the folder path of .NET Core test project in settings.json In .NET Test Explorer of Explorer view, all the tests will be automatically detected, and … Read more
