The evolution of software testing methodologies

Software testing has evolved alongside the development of software itself. In the past, testing was a significant stage in the waterfall model of software development. However, as the software development landscape has changed, so has the approach to testing. The core purpose of testing remains the same - to assess product quality and ensure a positive user experience. Functional and non-functional testing are still essential, but the way they are tackled has changed. Testing requirements are broken down into unit testing, integration testing, and end-to-end testing. Test cases are optimized to minimize test code liability and overall maintenance. Additionally, test cases are strategically crafted to ensure comprehensive coverage while minimizing code sprawl.
