Category Usage

Cause

A test class is not following one or multiple points of the required test class layout.

Rule description

Test classes (classes marked with the [TestClass] attribute) should follow the given layout to be considered valid by MSTest:

  • they should be public (or internal if the [assembly: DiscoverInternals] assembly attribute is set)
  • they should not be static
  • they should not be generic

How to fix violations

Ensure that the class matches the required layout described above.

When to suppress warnings

Do not suppress a warning from this rule. Ignoring this rule will result in tests being ignored, because MSTest will not consider this class to be a test class.

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 MSTEST0002
// The code that's violating the rule is on this line.
#pragma warning restore MSTEST0002

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

[*.{cs,vb}]
dotnet_diagnostic.MSTEST0002.severity = none
