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
• Debugging test failures in Ava
• Managing asynchronous tests with Ava
• Enhancing performance of Ava test suites

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

Quality Checklist

• Tests are clean and adhere to Ava's syntax
• Each test case verifies a single unit of behavior
• Utilize Ava's power-assert for detailed assertions
• Async code is handled using async/await correctly
• Global variables are avoided within tests
• Execution times of test suites are optimized
• Errors and warnings in console are addressed
• DRY principle applied across test files
• Constant test suite runtime across environments
• Comprehensive code coverage with Ava's built-in support

Output

• Efficient test execution leveraging Ava's concurrency
• Error messages with detailed and actionable information
• Consistent and reproducible test results
• Codebase with >85% test coverage
• Collection of tests that are quick to execute and diagnose
• Report of potential performance bottlenecks in tests
• Setup for continuous integration with Ava
