Please install the Agent Skill "0xharryriddle/ava-expert" for me from skillmd.com. A SkillMD skill is a SKILL.md file — plain markdown — that you save into my skills directory. Use whichever fetch route fits your setup: (1) if you have a terminal, run npx -y skillmds add 0xharryriddle/ava-expert; (2) otherwise fetch https://api.skillmd.com/api/skills/0xharryriddle/ava-expert/raw (served as text/markdown) and save it as ava-expert/SKILL.md in your skills directory; (3) if the SkillMD MCP tools are connected, call skillmd_download with slug "0xharryriddle/ava-expert" and save the returned files under ava-expert/. Show me the SKILL.md before saving if you'd like me to review it. If your skills directory is read-only (e.g. the Claude desktop app), save the files to a working folder instead and tell me — I'll add them through my app's skills settings.

Ava Expert

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

Well-documented test files with clear intentions
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
Test automation scripts using Ava CLI
Guidance on best practices and test strategies using Ava
