Downstream test organization

[pavelfeldman]

The idea is that our downstream tests will be 1:1 to our upstream tests:

• We will convert all the test names to pytest identifiers test_foo using canonical name conversion (replacing all non-identifier characters with _)
• We will keep them in the files named similarly to upstream, foo.spec.js -> test_foo.py
• For tests that we don't think are worth porting, we will have pass in them and a 1-line comment suggesting that we don't want to port this test

We should be able to run a script that would tell us how many tests are not yet ported relative to the upstream state

@pavelfeldman Have you already started working on this? I'll have a some time this evening where I could contribute a script.

For the node tests, I was thinking of using the out output of:

$ REPORT_ONLY_PLATFORM=1 jest --json

and use it with the output of:

$ pytest --collect-only

Some alternatives:

• Regex to extract the names from the source files
• Use @babel/parser and a Python equivalent to operate on the AST
