Automated testing in Visual Studio Team Services (VSTS) helps improve software quality through unit testing, code coverage analysis, static code analysis, web testing, load testing, and test case management. These tools help identify defects earlier, reduce bugs that impact users, and allow for more confident code changes through repeated regression testing. Specifically, unit testing tests individual code units independently and is important for finding a large percentage of defects during development.

2. Quality Challenges “ Software bugs, or errors, are so prevalent and so detrimental that they cost the U.S. economy an estimated $59.5 billion annually, or about 0.6 percent of the gross domestic product…an estimated $22.2 billion, could be eliminated by an improved testing infrastructure that enables earlier and more effective identification and removal of software defects.” (Source: NIST 2002) Satisfying users Business interruption risks Ongoing maintenance costs rising Less avail. resources
