[arquillian-issues] [JBoss JIRA] (ARQ-1684) Jacoco extension filters do not work as advertised

Jacoco extension filters do not work as advertised -------------------------------------------------- Key: ARQ-1684 URL: https://issues.jboss.org/browse/ARQ-1684 Project: Arquillian Issue Type: Bug Components: Extension - Jacoco Affects Versions: jacoco_1.0.0.Alpha6 Reporter: Rich DiCroce Assignee: Hemani Katyal Fix For: jacoco_1.0.0.Alpha9 The Jacoco includes/excludes mechanism does not work the way the [1.0.0.Alpha5 release announcement|http://arquillian.org/blog/2012/11/27/arquillian-extension-j...] implies it does. Specifically, the release announcement shows excluding a package and then including some sub-packages. This implies that includes have precedence over excludes, but that is not true. It's clear from looking at the source code that includes and excludes just get turned into filters that are all ANDed together. So if you have exclude some.package.* include some.package.foo.* then some.package.foo will not be included because the exclude for some.package will return false. Effectively, excludes have priority over includes. This would be fine if not for the fact that an "include everything" filter is automatically added. This, combined with exclusions having priority, breaks a key use case, namely: I want to exclude all packages that are not my own code. I can't just include my.package.* because of the automatic include all filter, and I can't exclude * include my.package.* because the exclude blocks out the include. Including everything is a problem because then so many classes have to be instrumented that the test just hangs and the archive never gets deployed. For me, this makes the Jacoco extension completely unusable.
