This was the original intent for this class, but there was no test to ensure that the sites listed did not have their detection method changed. Now, the test will fail if it does not really cover a given category.
On the flake8 test selection, this PR does _not_ focus on "_style violations_" (the majority of flake8 error codes that [__python/black__](https://github.com/python/black) can autocorrect). Instead these tests are focus on runtime safety and correctness:
* E9 tests are about Python syntax errors usually raised because flake8 can not build an Abstract Syntax Tree (AST). Often these issues are a sign of unused code or code that has not been ported to Python 3. These would be compile-time errors in a compiled language but in a dynamic language like Python they result in the script halting/crashing on the user.
* F63 tests are usually about the confusion between identity and equality in Python. Use ==/!= to compare str, bytes, and int literals is the classic case. These are areas where __a == b__ is True but __a is b__ is False (or vice versa).
* F7 tests logic errors and syntax errors in type hints
* F82 tests are almost always _undefined names_ which are usually a sign of a typo, missing imports, or code that has not been ported to Python 3. These also would be compile-time errors in a compiled language but in Python a __NameError__ is raised which will halt/crash the script on the user.
The data.json file is easy to add to, so users will be able to maintain their own forks. This is not ideal. Maybe there could be another repo with an adult data.json? That would avoid forks getting out of date.
