A parameterized test in Android (typically using JUnit4 or JUnit5 with AndroidX Test) is best used when you want to run the same test logic multiple times with different inputs. This helps improve code coverage and ensures your logic works correctly across a variety of inputs.
Regular Test Fixtures:
Drawbacks:
- Fails Entire Loop on First Assertion Failure
- No Granular Reporting in Test Output
- Harder to Debug, Stack traces are less helpful than in named parameterized methods.
- You can’t click-to-run or inspect individual input-output combinations in the test runner
- Manual Maintenance, we manually iterating, matching, and asserting.
