Measure code coverage of Java applications testing them at GUI level

[antoni...@gmail.com]

Hi!

I would like to measure code coverage of java applications with JaCoCo, but I want to measure it while testing the applications at the GUI level, without using unit tests. If someone has done it or know how it could work it would be great!

Thanks.

Hi,

Actually the same way as with unit tests

1. run your application with JaCoCo agent ( see http://www.jacoco.org/jacoco/trunk/doc/agent.html ) to obtain exec file
2. generate report based on exec file, class and source files of application by using small Ant script with Report Task ( see http://www.jacoco.org/jacoco/trunk/doc/ant.html ), or by using not yet released Command Line Interface ( see http://www.jacoco.org/jacoco/trunk/doc/cli.html ), or by calling JaCoCo APIs directly ( see ReportGenerator.java at http://www.jacoco.org/jacoco/trunk/doc/api.html )

You can use offline instrument and run the instrumented app, click on your GUI then shutdown the JVM.
