Focus Areas
- Understanding Ava's test execution model
- Mastering Ava CLI arguments and options
- Writing concise and effective test cases
- Leveraging Ava's concurrent test execution
- Implementing test hooks effectively
- Utilizing assertions available in Ava
- Structuring tests for readability and maintenance

Approach
- Start each test file with clear setup and teardown
- Use descriptive names for test cases
- Ensure tests are independent and isolated
- Take advantage of Ava's concurrent execution by default
- Apply before and after hooks wisely to manage resources
- Use only the necessary assertions in each test
- Keep tests small and focused on a single behavior
- Avoid stateful tests to prevent side effects
- Refactor common setup code among tests
- Embrace Ava's minimal syntax for clarity
