Test Automation

With expertise in Test Automation, you become the person automating away repetitive testing work. Instead of manually clicking through the same test cases every release, you build frameworks that test automatically in CI/CD pipelines. Your code tests their code—and catches bugs before production.

What You'll Actually Be Doing

As the Test Automation go-to person, your Wednesday might start with fixing flaky tests that randomly fail (the bane of automation), then building a new test framework for the microservices architecture, followed by integrating tests into CI/CD so every commit gets automatically tested.
  • Build and maintain automated test frameworks
  • Write automated tests for frontend, backend, and APIs
  • Integrate tests into CI/CD pipelines for continuous testing
  • Debug and fix flaky or unreliable tests
  • Generate test reports and metrics on test coverage
  • Collaborate with developers to improve testability

Version Control

FOUNDATION
Git, GitHub, GitLab, Bitbucket
Git appears in ~15-20% of QA Automation Engineer postings overall and ~15% at entry level. GitHub, GitLab, and Bitbucket add incremental coverage. Combined version control mentions reach ~20%. Git proficiency is essential for managing test automation code—a fundamental professional skill.

Performance & Load Testing

COMPLEMENTARY
JMeter, LoadRunner, Gatling, Performance testing tools
JMeter appears in ~5% of QA Automation Engineer postings. LoadRunner and other performance tools each appear in <5%. Combined performance testing mentions reach ~10%. Performance testing complements functional automation but represents a distinct specialization. Valuable but not universally required.

Enterprise Test Tools

NICE-TO-HAVE
Tosca, UFT, Robot Framework, Katalon
Commercial and enterprise test tools appear in <5% of QA Automation Engineer postings individually. Tosca appears in ~5% overall and ~10% at entry level. These represent employer-specific tool choices—skills are transferable between platforms, making specific tool expertise helpful but not critical.

Skills Insights

1. Programming Required

  • QA automation is software development
  • Java, Python, JavaScript common
  • Scripting insufficient
Automation engineer = developer who tests.

2. Framework Knowledge Critical

  • Selenium, Cypress, TestNG
  • Framework choice matters
  • Integration with CI/CD
Right framework for right context.

3. Maintenance Is The Challenge

  • Writing tests easier than maintaining
  • Flaky tests enemy
  • Stable, reliable automation valued
Anyone writes tests. Pros maintain them.
