What is Branch Coverage in Unit Testing?
Branch coverage in unit testing is a metric that measures the percentage of branches (decision points) in the source code that have been executed during the testing process. It indicates how well the test cases navigate through different possible outcomes of conditional statements, helping evaluate the thoroughness of testing. A high branch coverage means that most decision paths in the code have been tested, increasing the likelihood of detecting potential defects.
- Achieving comprehensive branch coverage is important for ensuring the reliability and effectiveness of unit tests in identifying and addressing code issues.
- This metric helps identify areas of code that may not have been adequately tested, increasing the likelihood of detecting potential defects and enhancing the overall reliability and quality of the software.
Formula for Branch Coverage:
Branch Coverage = (Total Number of Branches) Ă· (Number of Executed Branches) âś• 100%
What is Branch Coverage in Unit Testing?
Unit Testing is the process of writing the test cases for each developed code file. This testing is carried out by developers. Once the coding part is done, the developers will write the test cases to cover each scenario in the developed file. While running the test suites or test files, we can see there are four parts of coverages. They are Branch Coverages, Statement Coverages, Functions Coverages, and Condition Coverages. It includes the percentage covered for each coverage category. In this article, we will explore the concept of Branch Coverage in Unit Testing.
