Core Software Testing Metrics to Monitor
Navigating testing metrics in software can be hard. Many metrics give helpful information. But, it’s important to focus on the key ones. These key metrics greatly affect software quality and testing efficiency.
The main things to look at are defect density and test case effectiveness. Defect density tells you how many defects are in the lines of code. This helps you understand the quality of the software. Test case effectiveness checks how good your test cases are at finding defects compared to the total number of tests run. By focusing on these things, teams can get better and work on what matters most.
Defect Density and Its Calculation
Defect density is an important part of software testing. It checks the number of defects in a software product compared to its size. A lower defect density means better software quality. You usually calculate this measure using the number of defects found in every thousand lines of code, which is known as KLOC.
To find defect density, divide the total number of defects by the size of the software module in KLOC. For instance, if a module has 50 defects and has 10,000 lines of code, you calculate the number of bugs by getting 5 defects per KLOC.
It’s important to keep an eye on defect density during software development. By checking this number regularly and in different areas of the software, teams can spot places with more defects. This helps them enhance testing and boost the quality of the software overall. Also, comparing defect density to industry standards can give better insight into how testing is progressing and the quality of the software being created.
