Cause

A test method sets a DisplayName (on TestMethodAttribute or DataRowAttribute) to a value that's identical to the test method name.

Rule description

Setting a DisplayName to a value that's identical to the method name is redundant, because the method name is already used as the display name by default. The redundant DisplayName can be removed without changing how the test is reported.

[TestClass]
public class MyTestClass
{
    [TestMethod("Test")] // Violation: same as the method name.
    public void Test()
    {
    }
}

How to fix violations

Remove the redundant DisplayName.

[TestClass]
public class MyTestClass
{
    [TestMethod]
    public void Test()
    {
    }
}

A code fix is available.

When to suppress warnings

It's safe to suppress this warning if you intentionally set the display name explicitly, for example to keep it stable if the method is later renamed.

Suppress a warning

If you just want to suppress a single violation, add preprocessor directives to your source file to disable and then re-enable the rule.

#pragma warning disable MSTEST0071
// The code that's violating the rule is on this line.
#pragma warning restore MSTEST0071

To disable the rule for a file, folder, or project, set its severity to none in the configuration file.

[*.{cs,vb}]
dotnet_diagnostic.MSTEST0071.severity = none
