Title Test methods should have valid layout
Category Usage

Default severity Warning
Introduced in version 3.2.0

Cause

A test method is not following single or multiple points of the required test method layout.

Rule description

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

  • they should be public (or internal if [assembly: DiscoverInternals] attribute is set)
  • they should not be static
  • they should not be generic
  • they should not be abstract
  • they should return void or Task
  • they should not be async void
  • they should not be a special method (constructor, finalizer, operator...)

How to fix violations

Ensure that the test method 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 method to be a test method.
