code-level recipes - reading the exec file, reading project coverage data at class and line level

[julian...@gmail.com]

Hi Everyone,

I'm looking for (for want of a better word) JaCoCo internals recipes.

I can do the following in Cobertura.

1. Read .ser file
http://alvinalexander.com/java/jwarehouse/cobertura-1.9/src/net/sourceforge/cobertura/coveragedata/CoverageDataFileHandler.java.shtml
(Where the equivalent in Jacoco is the exec file)

Store in CoverageData
https://github.com/cobertura/cobertura/blob/master/cobertura/src/main/java/net/sourceforge/cobertura/coveragedata/ProjectData.java
(I don't know what the overall project level data is called in Jacoco).

Pull out classData
https://github.com/cobertura/cobertura/blob/master/cobertura/src/main/java/net/sourceforge/cobertura/coveragedata/ClassData.java
(I don't know how to retrieve coverage data at a class level from the exec file in Cobertura)

Pull out LineData
https://github.com/cobertura/cobertura/blob/master/cobertura/src/main/java/net/sourceforge/cobertura/coveragedata/LineData.java
(I don't know how to pull code the data at a line-level of covered/uncovered code in Cobertura).

Can someone point me do how to do the same in JaCoco?
1. Read the exec file
2. Pull out the data at a project level
3. Pull out data at a class level
4. Pull out data at a line-level.

Cheers
Julian

Hi,

Please read documentation at http://www.jacoco.org/jacoco/trunk/doc/

In particular there is API Usage Examples - http://www.jacoco.org/jacoco/trunk/doc/api.html

Such as http://www.jacoco.org/jacoco/trunk/doc/examples/java/ReportGenerator.java

that shows how to read exec file and generate report.
