Run Regression Test Suite

|

This module calls down into individual test cases via subprocess. It will
|
||||
forward all unrecognized arguments onto the individual test scripts, other
|
||||
than:
|
||||
|
||||
- `-extended`: run the "extended" test suite in addition to the basic one.
|
||||
- `-win`: signal that this is running in a Windows environment, and we
|
||||
should run the tests.
|
||||
- `--coverage`: this generates a basic coverage report for the RPC
|
||||
interface.
|
||||
|
||||
For a description of arguments recognized by test scripts, see
|
||||
`qa/pull-tester/test_framework/test_framework.py:BitcoinTestFramework.main`.
