testRun method

@visibleForTesting Future<List<AnalysisError>> testRun(ResolvedUnitResult result, { Pubspec? pubspec, })

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.
