Test coverage is a crucial aspect of software testing that helps ensure the quality and reliability of an application. Here are the different types of test coverage based on the provided search results:
1. Statement Coverage
This type of coverage measures the percentage of executable statements in the code that have been executed by the test cases. The goal is to ensure that every line of code is tested at least once.
2. Branch Coverage
Branch coverage checks whether each branch (or decision point) in the code has been executed. This ensures that both the true and false paths of conditional statements are tested.
3. Function Coverage
This type measures the percentage of functions or methods in the code that have been called during testing. It ensures that all functions are tested for their expected behavior.
4. Line Coverage
Line coverage measures the percentage of lines of code that have been executed during testing. It is similar to statement coverage but focuses specifically on the lines of code.
5. Condition Coverage
Condition coverage evaluates whether each boolean expression in the code has been tested for both true and false outcomes. This helps ensure that all logical conditions are verified.
6. Requirement Coverage
This type measures how many of the specified requirements (functional and non-functional) have been tested. It helps ensure that the application meets all user requirements.
7. Product Coverage
Product coverage assesses which parts or modules of the application have been tested against the total number of parts available. It helps identify untested areas within the application.
8. Risk Coverage
Risk coverage focuses on identifying and testing high-risk areas of the application. It prioritizes testing based on the potential impact of failures.
9. Boundary Value Coverage
This type ensures that boundary values for input fields are tested. It checks the limits of acceptable input values to identify any potential issues.
10. Compatibility Coverage
Compatibility coverage tests the application across different devices, browsers, and operating systems to ensure consistent functionality and appearance.
Conclusion
Each type of test coverage serves a specific purpose and helps in identifying different aspects of the software that need testing. By employing a combination of these coverage techniques, testers can enhance the overall quality and reliability of the software application.
