How to register a unit test record and leave it in MSTest

Question

I am using MSTest and I want to write a log entry before and after the test finishes. Obviously, I don’t want to add custom logging code at the beginning and at the end of each test - this would only make the test unreadable and seem like a lot of effort (I have> 500 tests)

Using TestInitialize and TestCleanup seemed like a way, but I can't get the name of the test.

Does anyone know how to do this?

Answer 1

In MSTest, the name of the test case is available in the validation context property . Thus, to access it in the test initialization method (as well as the test), you can use something like this: -

[TestInitialize()] public void MyTestInitialize() { if (string.Equals(**TestContext.TestName**, "TestMethod1", StringComparison.OrdinalIgnoreCase)) { } }

We use nLog for logging and the base class to test initialization and check for cleanup, which is logged if the test passes or not.

This is the base class:

 using Microsoft.VisualStudio.TestTools.UnitTesting; using NLog; namespace Tests { public class TestBase { private static readonly Logger Logger = LogManager.GetCurrentClassLogger(); public TestContext TestContext { get; set; } [TestCleanup] public void TestCleanup() { string testName = string.Format("{0}.{1}", TestContext.FullyQualifiedTestClassName, TestContext.TestName); UnitTestOutcome currentTestOutcome = TestContext.CurrentTestOutcome; string message = string.Format("Test '{0}' {1}", testName, currentTestOutcome.ToString().ToUpperInvariant()); if (currentTestOutcome != UnitTestOutcome.Passed) { Logger.Error(message); } else { Logger.Info(message); } } [TestInitialize] public void TestInitialize() { string testName = string.Format("{0}.{1}", TestContext.FullyQualifiedTestClassName, TestContext.TestName); Logger.Info("Started with test '{0}'", testName); } } } 

And here is its use

 using Microsoft.VisualStudio.TestTools.UnitTesting; namespace Tests { [TestClass] public class JustTest : TestBase { [TestMethod] public void Fail() { Assert.IsTrue(false); } [TestMethod] public void Pass() { Assert.IsTrue(true); } } } 

here is the part from the log file

 Started with test 'Tests.JustTest.Fail' Test 'Tests.JustTest.Fail' FAILED Started with test 'Tests.JustTest.Pass' Test 'Tests.JustTest.Pass' PASSED

Update: Now I see what you are getting at. The bad news: I do not use MSTest or MSTest to find out ...

In NUnit you can

 >"nunit-console.exe" API_Tests.dll /out:My.log /labels 

This displays the following log file

 ***** Test.Gumba.API_Tests.Tests.ArithmeticProgression.DummyTest2 Woohoo! made it till test2 ***** Test.Gumba.API_Tests.Tests.ArithmeticProgression.GeneratesTheRightProgressionAsSpecifiedByTheUser Try#0 failed. due to 0. Retrying NUnit.Framework.AssertionException: Expected is <System.Int32[10]>, actual is <System.Int32[0]> <snipped>... 

I was looking at command line switches for MSTest , and the following looks interesting

 mstest /testcontainer:Some.dll /detail:testname 

--------------- previous answer follows -----
To answer your question, the Run method can be executed using the method that the delegate accepts. However, if you could clarify why you need it, perhaps there is a better solution to achieve what you after

eg.

 private void LogAround(Action action) { // log entry with calling method name using StackTrace class action(); // log exit } 

and the challenges will be

 Do( delegate { // test code });
