Tell us what’s happening:
I’m having some issues with the provided unit tests in the Arithmetic Formatter challenge.
When run individually, each test in the default test_module.py works fine. But when run altogether (as the starter code is set up to do), several of them fail. Output from the console shows that some tests are re-using the parameters from previous tests as well, causing an issue with the output.
For example, here is one unit test that should be using the parameters [‘1 + 2’, ‘1 - 9380’], but for some reason inputs from the first unit test are mixed in ([‘3801 - 2’, ‘123 + 49’]):
Would anyone have some insights into why this might be causing so many issues? Again, commenting out the interfering tests means that I can get each to work on their own, which is super odd.
