**SUMMARY**

Test names must be unique per scope otherwise the second test overrides the first one with the same name.

**ISSUE TYPE**
- Bugfix Pull Request

**COMPONENT NAME**
ansible/test/units/parsing/test_mod_args.py
ansible/test/units/module_utils/facts/test_collectors.py
ansible/test/units/module_utils/common/validation/test_check_required_if.py
ansible/test/units/module_utils/basic/test_deprecate_warn.py

**ADDITIONAL INFORMATION**

For example if you had a test file that does:

```
def test_a():
    pass

def test_a():
    pass
```

Then only the second `test_a` will be ran. More details [here](https://codereview.doctor/features/python/best-practice/avoid-duplicate-unit-test-names).

These are the tests that are overriding previously defined tests due to this problem:
