To ensure that all developers work in a harmonized manner the source code should reflect a harmonized style as a single developer had written the entire code in one session, the developers should be aware of the coding guidelines before starting a software project. Good tools can look for sloppy errors like uninitialized variables and deeper problems like buffer overruns or sql injection vulnerabilities. In software testing, defect clustering means small modules and functionality have most of the operational failures. Including more details about defect clustering, pareto principle and pesticide paradox. The success of any project depends on the testing done on it.
