What is cobertura used for?
Cobertura is a free Java tool that calculates the percentage of code accessed by tests. It can be used to identify which parts of your Java program are lacking test coverage. It is based on jcoverage.
What is cobertura coverage report?
Simply put, Cobertura is a reporting tool that calculates test coverage for a codebase – the percentage of branches/lines accessed by unit tests in a Java project.
How do you cover a test code?
To calculate the code coverage percentage, simply use the following formula: Code Coverage Percentage = (Number of lines of code executed by a testing algorithm/Total number of lines of code in a system component) * 100.
What does GCOV do?
Gcov is a source code coverage analysis and statement-by-statement profiling tool. Gcov generates exact counts of the number of times each statement in a program is executed and annotates source code to add instrumentation. Gcov comes as a standard utility with the GNU Compiler Collection (GCC) suite.
How do I use the gcov command?
To use Gcov, perform the following steps:
- Compile the code with the -fprofile-arcs and -ftest-coverage flags, for example: $ gcc -fprofile-arcs -ftest-coverage test.c.
- Run the instrumented binary and perform functional testing.
- Generate a report file based on the data that is stored in the profile output files:
How do I get code coverage report in Eclipse?
The plugin can be easily installed from its update site at http://update.eclemma.org/ on any Eclipse installation of version 3.5 or above. It is also available from the Eclipse Marketplace. After you have installed the plugin, you can run your tests using the new Coverage As launch configuration.
How do I increase my line coverage?
There are a number of approaches:
- Write More Tests.
- Generate Tests Automatically.
- Remove Dead/Zombie Code.
- Remove Redundant/Cloned Code.
- Write/Execute More Sophisticated Tests.
How do you make sure that your test coverage is good?
How Do You Ensure Test Coverage Is Good?
- Create a comprehensive testing strategy.
- Create a checklist for all of the testing activities.
- Prioritize critical areas of the application.
- Create a list of all requirements for the application.
- Write down the risks inherent to the application.
- Leverage test automation.
What is a good level of code coverage?
With that being said it is generally accepted that 80% coverage is a good goal to aim for. Trying to reach a higher coverage might turn out to be costly, while not necessary producing enough benefit. The first time you run your coverage tool you might find that you have a fairly low percentage of coverage.
