Performance testing is the process of simulating user activity on a website or application with the aim of finding performance bottlenecks (weaknesses) and vulnerabilities (faults). Automated performance tests are needed because testing manually would be time-consuming and expensive; some computerized solutions can even create detailed performance benchmarks that may be used to track the system’s capacity over time.
This article features some popular automated performance testing tools, which you can use for load, stress, and functional testing.
