The testing guide does not mention where a test should be added

https://github.com/nodejs/node/blob/master/doc/guides/writing-tests.md

1. It does not mention how to determine which folder a new test should go to: parallel, sequential, or any other folders under test
   2. It does not mention how the test should be named (if it's a new test script) It does
2. It does not mention how to find existing test cases and how to decide if a new test case belongs to a new file or an existing file.

@joyeecheung could you please ellaborate when should one test be gone under parallel or any other folder?

@juggernaut451 See https://github.com/nodejs/node/tree/master/test#test-directories. In practice, most tests go into parallel unless there is something special about them that they need to be put in other directories.
