What you’ll learn
  • How to cache test results and rerun only failed tests
  • How to reduce CI time by 40-60%
  • Which CI providers support these optimizations
TestDino optimizes Playwright test execution in CI pipelines by caching test results and enabling selective reruns.

​
Quick Reference

StrategyDescription
Rerun Only Failed TestsCache results and rerun only failed tests. Reduces CI time by 40-60%.

​
The Problem

Running full test suites on every commit increases time and cost:
  • Long feedback loops - Full suites take 10-30+ minutes, delaying developer feedback
  • High CI costs - CI minutes accumulate quickly across teams and branches
  • Slow deployments - Waiting for full test runs slows release velocity
  • Flaky test noise - Re-running everything amplifies flaky test impact and blocks merges

​
How TestDino Extends Playwright

Playwright @playwright/[email protected]+ includes native --last-failed support. TestDino adds:
  • Cross-runner caching - Results persist across different CI runners
  • Shard awareness - Works with parallelized test execution
  • Workflow-level persistence - Cache survives job restarts
  • Branch/commit tracking - Results tied to specific code changes
Re-run failed tests, GitHub Actions, and status checks.
