Coverage Metrics
Overview Let’s look at some code coverage tools and the official URLs used for test coverage analysis of the Java source code. Cobertura Emma JaCoCo Cobertura Cobertura is a free Java-based code coverage reporting tool that calculates the test coverage of the source code by the tests. The tool is based on jcoverage. Official URL: […]
Overview Method or Function Coverage is a metric that checks if each method in the application source code is executed or covered by the tests. Method Coverage Mathematical formula for Method Coverage is as follows: Method Coverage = Example Sample Method Counters data: Covered Methods = 6 Total Methods = 8 Method Coverage = (6/8) […]
Overview Branch coverage is a code coverage metric to check that all the branches in the application source code are tested at least once. Branches occur in the program code when we use conditional or branching statements. Examples if statement nested if-else ladder switch case statements looping statements like for, while, etc. Branch Coverage The […]
Overview Statement Coverage is a code coverage metric that indicates the percentage of code statements exercised during the test run. Statement Coverage reports whether each executable statement is encountered. It is a White-box testing technique. It is also called Line Coverage. Statement Coverage The mathematical formula is as follows: Statement Coverage requires all statements […]
Overview In this tutorial, we will learn different types of Code Coverage Metrics. Code Coverage Testing is a Whitebox Testing technique that measures the extent of code exercised or executed during the test. We need to execute the code to get the code coverage analysis. So, it is a dynamic testing technique. Types of Code […]
Overview Data flow coverage is a metric used in software testing to assess the thoroughness of testing concerning data flow within a program. It focuses on tracking the propagation of data values through different paths in the code, aiming to identify areas where data dependencies and interactions may lead to defects. Data Flow Coverage Data […]
