Previously, the
Bash.testhelper did not capture stdout or stderr,causing them to be None. This meant that the assertion
not stdoutwas always true (vacuously), and if a test failed, the error message
contained no output.
Changed the assertion and also the assertion failure message to not
hide the "None/None" issue.
This commit adds output capturing to
subprocess.Popenand decodesit as utf-8, ensuring that test failures provide useful debugging
information.
