Chapter 9. Monitoring Performance Regressions
This chapter will cover writing automated tests to monitor performance along with adding these to a Continuous Integration (CI) and deployment system. By constantly checking for regressions, you'll avoid accidentally building a slow application. We'll also cover how to safely load test a system without forcing it offline and how to ensure that tests mimic real life usage as far as possible.
Topics covered in this chapter include the following:
- Profiling
- Load testing
- Automated testing
- Performance monitoring
- Continuous integration and deployment
- Realistic environments and production-like data
- UI testing with selenium and phantom headless browsers
- A/B testing for conversion optimization
- Cloud services and hosting
- DevOps
You will see how to automate performance monitoring and testing so that you don't need to remember to keep doing it manually. You'll learn how to catch regressions early before they cause trouble and how to safely...
