+## Verifying Quickfixes
+
+Lint's test support will also attempt to verify that your quickfixes
+still produces a valid Kotlin, Java or XML source file. It does this
+by parsing these files after testing the quickfixes using
+`expectFixDiffs()`. It will only complain if the fixed source file didn't
+already have parsing errors *before* applying the fix.
+
+You can control this behavior using the `.verifyFixedFileSyntax()` method
+on the `lint()` task.
