List of an ideas concerning test automation. Based on my and other people’s experiences.

Engineering practices for test automation

  • Use tools to speed up testing
  • Always pay technical dent
    Self-service infrastructure — everything must start (tests, or environments) with one button
  • Self documented tests — everything has to be in the code, documentation becomes obsolete
  • Postmortem should be conducted and documented after each incident

Testing automation framework

  • Use VCS to store a code, use GitFlow to provide changes safely
  • Automatic rollout of a new version
  • Unified style of code and tests
  • Tests can be executed in any environment without complicated preparations
  • Test automation framework and test scripts also should be tested
    — Unit tests for the framework
    — Test scope with the smoke tests
  • Clean and useful logs
  • Use profiler to find and optimize bottlenecks
  • Rerun failed tests

Test scripts

  • Test scripts it’s a common property — they should be clear for everyone, and everyone can maintain it.
  • Self documented tests — test documentation should be generated
  • Have a set of stable tests


  • Use metrics to improve testing process
    — How stable are the tests?
    — How fast are the tests?
    — How fast are we writing tests?
    — What are the most common problems?
  • Visualize metrics


  • Generate coverage report
  • Integrate tests into CI/CD
  • Test results should be visible for everyone
  • Cause of test failure should be clear for everyone
  • Collect feedback to improve test framework
    — End users of a tests framework not only QA team, but all project members

Flexible test control

  • Use tags to include and exclude tests from a test execution
    — Positive / Negative
    — Stable / Unstable / Smoke

Health check for the automation test

  • Is it still valid?
  • Is it hard to maintain?
  • How much fail causes this test has?
  • What will be if we don’t catch this bug

Increase trust to test automation

  • Run only stable tests
  • Every test should have only one reason for failure
  • Understand the cause of each and every test failure
  • Weed out flaky tests like weeds

Reduce test execution time

  • Parallelism
  • Cache code dependencies
  • Reduce the number of tests
  • Set a time limit (what I can test in 10/30/60 minutes)

Cross-functional teams

  • Know what the other teams are doing
  • Other teams should known what QA is doing
