I want to get the Code Coverage of some simple test, which gets data from a DataProvider. I need the coverage result for each data that runs through the test. For example:

if (value != 0)
{
   //do something
}

if (value == 100) {
   //do something
}
   //else do something

If the test gets a value like 0 from the DataProvider, it never reaches the first part of the code, so the coverage result is different than if the value was 100. So how do I get those coverage results for each data? I am using jacoco with the maven plugin...

It maybe would help, if there is a possibility to run the subtests with maven... Currently I am doing this:

mvn test

but I want to do something like this:

mvn -Dtest=myTestClass#myTest#myData (#myData of course not working)

However IntelliJ uses this parameter to specifiy the subtest:

java.exe -ea [.......] @name0 //-> to run the test only with first Data
java.exe -ea [.......] @name1 //-> to run the test only with second Data
etc.

Thanks for your help in advance!

Code coverage is the percentage of code which is covered by automated tests. Code coverage measurement simply determines which statements in a body of code have been executed through a test run, and which statements have not. https://confluence.atlassian.com/clover/about-code-coverage-71599496.html

You can pass the arguments from command line and then run your tests. You can pass them on the command line like this

mvn test -Dtest=<ClassName> -Dvalue=100

then access them in your test with

int value=Integer.valueOf(System.getProperty("value"));
