I usually do the same but arrived at this by using a mental prefix of "test that". As in:
"this test tests that" input has length 256
Since the prefix would be equal for all the tests only the last part becomes the name.
"this test tests that" input has length 256
Since the prefix would be equal for all the tests only the last part becomes the name.
Now I consider that style boilerplate, and just write “X shall hold.”
