A Jest-compatible test runner with a custom minimal test framework implementation. It runs multiple test suites using describe/it/expect syntax and parses the results into a visual display.

What’s inside

• A custom Jest-like framework providing describe, it, and expect
• Three test suites: calculator, user service, and event bus
• Stdout parsing that extracts pass/fail counts from the runner output
• Visual result display with pass/fail indicators per test

Try it yourself

1. Click “Run Tests” to execute all test suites
2. Edit test files to add new test cases
3. Modify the source files and re-run to see failures
