Pipeline Optimization
5.1Why Speed MattersSlow pipelines erode developer trust. When the pipeline takes 45 minutes, developers stop waiting for it and merge anyway. When the…5.2CachingCaching is the single most impactful optimization. Without caching, every pipeline run downloads and installs dependencies from scratch…5.3ParallelizationSplit your test suite across multiple runners. Each runner executes a fraction of the tests, and the total wall-clock time is roughly…5.4Fail-Fast StrategyThe fail-fast setting controls whether other matrix jobs are cancelled when one fails.5.5Conditional ExecutionSkip expensive work when it is not needed.5.6Pipeline Configuration for Test PerformanceEnvironment variables that affect test speed:5.7Measuring Pipeline PerformanceTrack these metrics to identify optimization opportunities:5.8Advanced Optimization TechniquesExtract common patterns into reusable workflows to avoid duplication:5.9Hands-On Exercise1. Measure your current pipeline time end-to-end. Write down each stage's duration. 2. Add caching for dependencies and Playwright…
