Choose a profile and multiple suites

Use pure computation tests and give edge cases their own suite.

YOUR TASK

Make this happen

3 steps

Keep both test files in the content.test list.
Use content.test.profile = "pure" for this computation-only function.
Fix the zero-quantity expectation and run all suites.

Read the starter files
