Visual Studio does not run all the unit tests in a test class

Question

I have 3 test methods in my unit test class, but Visual Studio only runs the second test, ignoring the others

These are the 3 test methods:

[TestClass()]
public class InsertionSortTest
{

    [TestMethod()]
    public void sortTest()
    {
        InsertionSort target = new InsertionSort(); // TODO: Initialize to an appropriate value
        int[] n = new int[] { 2, 1, 4 };
        int[] nExpected = new int[] { 1, 2, 4 };
        target.sort(ref n);
        CollectionAssert.AreEqual(nExpected, n);

    }

    [TestMethod()]
    public void sortTest2()
    {
        InsertionSort target = new InsertionSort(); // TODO: Initialize to an appropriate value
        int[] n = new int[] { 1, 2 };
        int[] nExpected = new int[] { 1, 2 };
        target.sort(ref n);
        CollectionAssert.AreEqual(nExpected, n);

    }

    [TestMethod()]
    public void sortTest3()
    {
        InsertionSort target = new InsertionSort(); // TODO: Initialize to an appropriate value
        int[] n = new int[] { 1, 2 };
        int[] nExpected = new int[] { 1, 2 };
        target.sort(ref n);
        CollectionAssert.AreEqual(nExpected, n);

    }
}

So when I run the test only sortTest2 is executed? I am expecting 3 results from this. I am getting Results 1/1 passed. TestName: sortTest2.

What happened with the other two tests I made?

Answer 1

gillyb, yeah, you where right I think. Re-starting Visual Studio fixed the problem.

Answer 2

I have noticed tests being shown as "not run" after test run completed. Turned out these tests were never completed due to a StackOverflowException being thrown mid way.

Answer 3

Something that has bitten me more than once with this is that the test project was not checked to be built in the solution configuration.
