Test the test_framework, but don't use test_framework objects or functions to test itself Use python unittest library and put test_framework's unit tests inside their respective files Add the filename to TEST_FRAMEWORK_MODULES in test_runner Aggregate all test_framework tests into one TestSuite to run before the functional tests in test_runner Delete framework_test_script, move test_bn2vch to script.py and add to TEST_FRAMEWORK_MODULES in test_runner This is a backport of Core [[https://github.com/bitcoin/bitcoin/pull/18576 | PR18576]]
