Why does visual studio 2012 not find my tests?
I have some tests that use the built in Microsoft.VisualStudio.TestTools.UnitTesting , but can not get them to run.
I am using visual studio 2012 ultimate.
I have a solution of two projects; One has tests, using Microsoft.VisualStudio.TestTools.UnitTesting , [TestClass] before the class, [TestMethod] before the test methods and reference Microsoft.VisualStudio.QualityTools.UnitTestFramework (version 10.0.0.0, runtime version v2.0.50727). I have tried dot-net framework 3.5, 4 and 4.5 others give a re-targeting error.
I have tried to build the solution and project. Test explorer has the message `Build your solution to discover all available tests. Click "run all" to build, discover, and run all tests in your solution.
So the question is: How to I get visual studio to find the tests?
Have also tried to follow this: http://msdn.microsoft.com/en-US/library/ms379625%28v=VS.80%29.aspx but with no success: I get stuck in section getting started, when asked to right click and select create tests . There is no create tests .
I have this test(it compiles, but does not show up in test explorer):
using Microsoft.VisualStudio.TestTools.UnitTesting;
namespace tests {
[TestClass]
public class SimpleTest {
[TestMethod]
public void Test() {
Assert.AreEqual("a","a", "same");
}
}
}
I have now discovered (see deleted answer below) that it is because it is on a shared drive, but I don't as yet know how to get around it. (something about the security setting maybe).
I had same symptoms, but under different circumstances.
I had to add one additional step to Peter Lamberg's solution — Clean your solution/project.
My unittest project targets x64. When I created the project it was originally targeting x86.
After switching to x64 all my unit tests disappeared.
I had to go to the Test Menu -> Test Setting -Default Processor Architecture -> x64.
They still didn't show up.
Did a build.
Still didn't show up.
Finally did a Clean
Then they showed up.
I find Clean Solution and Clean to be quite useful at getting the solutions to play ball when setting have changed. Sometimes I have to go to the extreme and delete the obj and bin directories and do a rebuild.
Please add the keyword public to your class definition. Your test class is currently not visible outside its own assembly.
namespace tests {
[TestClass]
public class SimpleTest {
[TestMethod]
public void Test() {
Assert.AreEqual("a","a", "same");
}
}
}
This sometimes works.
Check that the processor architecture under Test menu matches the one you use to build the solution.
Test -> Test Settings -> Default Processor Architecture -> x86 / x64
As mentioned in other posts, make sure you have the Test Explorer window open. Test -> Windows -> Test Explorer
Then rebuilding the project with the tests should make the tests appear in Test Explorer.
Edit: As Ourjamie pointed out below, doing a clean build may also help. In addition to that, here is one more thing I encountered:
The "Build" checkbox was unticked in Configuration Manager for a new test project I had created under the solution.
Go to Build -> Configuration Manager. Make sure your test project has build checkbox checked for all solution configurations and solution platforms.
