#ci-cd

Continuous delivery demands confidence at every stage. Learn where QA fits in CD pipelines, how to build release confidence without slowing down, and how progressive delivery and feature flags enable.

Fast feedback on pull requests accelerates delivery. Learn how to design PR checks that catch real issues early, use path filters to skip irrelevant checks, and balance required vs. optional checks.

Failed CI runs are only useful if you can diagnose them quickly. Learn how to generate HTML reports, upload trace artifacts, establish ownership loops, and notify teams without creating alert fatigue.

Reproducible test environments are the foundation of reliable CI/CD. Learn how to use Docker Compose for local and CI E2E testing, and how to run smoke tests against ephemeral preview deployments.

Learn how to build fast, reliable CI pipelines with GitHub Actions. Master workflow syntax, dependency caching, matrix strategies, secrets management, and Playwright integration for scalable test.

Not every failure should block a merge. Learn which quality gates must block pipelines, which should inform, and how to design gates that prevent bad code from reaching production without slowing.

Playwright tests can run in parallel across multiple workers and even multiple machines. Learn how to configure workers, shard test suites for CI, collect trace and video artifacts, and set up a.

Tools don't solve testing problems — testers do. Learn the categories of test tools, the real risks of adopting new tools, and how to calculate the ROI of test automation before you invest.

Testing isn't something you do at the end. Learn how SDLC vs STLC thinking, continuous testing, and quality gates in CI/CD change how teams build software.

Flaky tests, bad selectors, environment dependencies, no strategy — discover the real root causes of automation failures and concrete fixes for each.
