▸case-23 When our nightly E2E test run fails in GitHub Actions, developers spend hours sifting through unformatted raw console stdout logs to figure out which test step failed.

▸case-03 We need to validate backend REST API response schemas and status codes for `/api/v1/orders` using Supertest.

▸case-02 Our team is tasked with automating tests for a legacy internal dashboard.

▸case-05 We are writing Playwright tests for an e-commerce checkout flow. The frontend developer suggested using dynamic auto-generated CSS class names like `.button-x7z9q` or deep DOM hierarchies like `div > form > div:nth-child(2) > button` for clicking the submit order button because adding custom HTML attributes requires a release build.
