LEARN. PRACTICE. GROW.Concept and mechanism
An automation solution needs objectives, ownership, and planned maintenance. Before multiplying scripts, demonstrate through a pilot that the team can prepare data, execute cases, and explain a failure. If several cases repeat the same behavior with different inputs, separate data can feed a common sequence. If the process varies, keywords can express domain actions such as prepare instruction, submit, and verify rejection. Each action should have a clear contract: preconditions, parameters, effects, and outcome. A keyword performing dozens of hidden operations makes failures difficult to understand. Reuse should reduce repetition without removing diagnostic information or mixing state across concurrent runs.
Guided application
Calculate benefit over time including development, infrastructure, maintenance, and failure analysis. Saving ten minutes per run does not automatically justify weeks of maintenance. Interface changes can make recordings fragile; choose levels and abstractions according to risks. When a test passes only after retry, preserve the distinction between initial success and intermittency. Playwright identifies that distinction in results, but restarting a worker does not guarantee a shared database has been reset. Connect reports to the version actually executed and define who investigates recurring failures. Automation aims to provide useful evidence sustainably, including limitations, rather than merely achieve a high percentage of automated cases.
A verify-rejection action must fail when a request was improperly accepted.
Common pitfalls
Opaque abstraction; retry treated as cure; initial cost without maintenance.
