Learn how to increase test coverage without slowing down release speed, a crucial balance for engineering teams

intermediate Published 8 Jun 2026
Action Steps
  1. Identify bottlenecks in the current testing process using tools like GitLab or CircleCI
  2. Implement parallel testing to reduce test execution time
  3. Configure automated testing frameworks like Jest or Pytest to run tests in parallel
  4. Apply a risk-based approach to testing, focusing on critical components and user journeys
  5. Test in production using techniques like canary releases or A/B testing to ensure quality without slowing releases
