Code Coverage vs Test Coverage

Code coverage and test coverage are two important metrics in software testing. While they are related, there are some key differences between them. Here are some of the main differences between code coverage and test coverage:

Code Coverage:

  • Code coverage is a quantitative measure of the effectiveness of code.
  • It measures the percentage of code executed during testing.
  • It is a white-box testing approach that examines the internal behavior of the code.
  • Code coverage tools use instrumentation to track which lines of code are executed during testing.
  • Code coverage can be time-consuming and costly to implement.

Test Coverage:

  • Test coverage is a qualitative approach that examines the external behavior of the program.
  • It measures the extent to which the tests cover the software’s requirements or functionality.
  • It is a black-box testing approach that examines the program’s external behavior.
  • Test coverage tools use test cases to verify that the software meets the requirements.
  • Test coverage is concerned with the entire scope of testing, including not only code execution but also functional requirements.

In summary, code coverage measures the percentage of code executed during testing, while test coverage measures the extent to which the tests cover the software’s requirements or functionality.

Code coverage is a white-box testing approach that examines the internal behavior of the code, while test coverage is a black-box testing approach that examines the program’s external behavior.

Both metrics are important for ensuring the quality and reliability of software, and developers should strive to achieve high levels of both code coverage and test coverage.

Gcov Code Coverage

Gcov is an open-source code coverage tool that is used to analyze code coverage in C and C++ programs on Linux. It is a part of the GNU Compiler Collection (GCC) suite and generates exact counts of the number of times each statement in a program is executed and annotates source code to add instrumentation.

 To use gcov, you need to compile the code with the -fprofile-arcs and -ftest-coverage flags, which cause gcc to add instrumentation codes to the binary.

 Then, you can run the instrumented binary and perform functional testing to generate profile output. For each source file that you compiled with -fprofile-arcs, a .gcdaprofile output file is created in the object file directory. Finally, you can generate a report file based on the data that is stored in the profile output files using the gcov command.

Gcov can measure different types of code coverage, including branch coverage and loop coverage.

Sonarqube Code Coverage
