🎯 Key Reasons Companies Want Performance Testing Skills​

1. Full-Stack Testing Capabilities​

Companies want testers who can handle both functional automation and performance testing, making teams more efficient and reducing hiring needs.

2. DevOps & CI/CD Integration​

Performance tests need to be automated in CI/CD pipelines just like functional tests, requiring similar automation skills and mindset.

3. Early Performance Feedback​

Modern development practices require performance testing earlier in the development cycle, integrated with functional test automation.

4. Cost Efficiency​

Hiring one person who can do both functional and performance testing is more cost-effective than hiring separate specialists.

5. Scripting & Programming Skills​

Both functional automation and performance testing require similar programming and scripting abilities, making the transition natural.

Load & Performance Testing​

  • JMeter - Open-source, most popular, Java-based
  • K6 - Modern, developer-friendly, JavaScript-based
  • Gatling - Scala-based, powerful reporting
  • Locust - Python-based, easy to learn

APM & Monitoring​

  • New Relic - Application Performance Monitoring
  • Dynatrace - Full-stack monitoring
  • AppDynamics - Business transaction monitoring

Cloud-Based​

  • BlazeMeter - JMeter in the cloud
  • LoadRunner - Enterprise-grade (paid)
  • Azure Load Testing - Cloud-native solution
