MSTEST0034: Use ClassCleanupBehavior.EndOfClass with the [ClassCleanup]

[NOTE] This analyzer is no longer relevant for MSTest 4 as ClassCleanupBehavior was removed.

Cause

This rule raises a diagnostic when ClassCleanupBehavior.EndOfClass isn't set with the [ClassCleanup].

Rule description

Without using ClassCleanupBehavior.EndOfClass, the [ClassCleanup] will by default be run at the end of the assembly and not at the end of the class.

How to fix violations

Use [ClassCleanup(ClassCleanupBehavior.EndOfClass)].

When to suppress warnings

It's not recommended to suppress warnings from this rule as you can use instead [AssemblyCleanup].

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 MSTEST0034
// The code that's violating the rule is on this line.
#pragma warning restore MSTEST0034

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

[*.{cs,vb}]
dotnet_diagnostic.MSTEST0034.severity = none
