In MSTest how to check if last test passed (in TestCleanup)

Question

I'm creating web tests in Selenium using MSTest and want to take a screenshot everytime a test fails but I don't want to take one every time a test passes.

What I wanted to do is put a screenshot function inside the [TestCleanup] method and run it if test failed but not if test passed. But how do I figure out if a last test passed?

Currently I'm doing bool = false on [TestInitialize] and bool = true if test runs through.

But I don't think that's a very good solution.

So basically I'm looking for a way to detect if last test true/false when doing [TestCleanup].

Solution

if (TestContext.CurrentTestOutcome != UnitTestOutcome.Passed)
{
    // some code
}

The answer by @MartinMussmann is correct, but incomplete. To access the "TestContext" object you need to make sure to declare it as a property in your TestClass:

[TestClass]
public class BaseTest
{
    public TestContext TestContext { get; set; }

    [TestCleanup]
    public void TestCleanup()
    {
        if (TestContext.CurrentTestOutcome != UnitTestOutcome.Passed)
        {
            // some code
        }
    }
}
