Hi,

JaCoCo/EclEmma has no idea about the nature of Java application which is running on the JVM. In particular has no notion of a "test case". Therefore this feature is not directly supported in JaCoCo or EclEmma.

But it is possible to build it on JaCoCo APIs. For example SonarQube has an implementation for this in their reports:

Hello everyone,

I am eager to know if Jacoco or EclEmma is able to provide coverage
matrix? Coverage matrix is matrix of test cases X lines covered, where
each row will be a vector of 1s and 0s. ! represents, corresponding
line is covered in that test case, represented by row. and 0 will
represent its counterpart. This matrix is useful in many
fault-localization methods. I go through documentation but didn't find
anything fruitful.

I would love to know if this is possible in jacoco or eclemma.
