This patch adds assertCheckPasses and assertCheckFails methods to make it easier to write tests for more complicated checks that we want to add. We rely on checks being generators at this point, meaning this will not work on flake8 class based plugins. Change-Id: I37ecec271006084211e37c4fc9c89d71df01dc97
