// implementation. It's good to enable these in both unit tests and browser
// tests, as a means of detecting bugs in the implementation of the content api.
//
// These checks should typically be enabled by the base class of any test
// framework that would instantiate a WebContents -- ContentBrowserTest::SetUp,
// RenderViewHostTestHarness::SetUp, and so forth. Individual tests won't
// typically need to enable them.
//
// For the nuts and bolts of what the checks enforce, see the implementation.
