  3. Pubspec? pubspec,
})
inherited

Runs this assist in test mode.

The result will contain all the changes that would have been applied by run.

The parameter pubspec can be used to simulate a pubspec file which will be passed to CustomLintContext.pubspec. By default, an empty pubspec with the name test_project will be used.
