I was trying to make this work but ran into a few walls of my own gradle
knowledge. I was doing this with a trivial project, not the whole of
lucene, so I'm sure there will be additional integration pains.
Regardless, sharing my progress thus far:
configure(rootProject) {
Integer.getInteger("beast.iters", 3).times {
tasks.create(name: "beastRun$it", type:Test)
}
task beast() {
dependsOn rootProject.collect {
tasks.matching { task -> task.name.startsWith("beastRun") }
}
}
}
I was able to get this to execute a test multiple times, and save the
output to separate test directories (build/test-results/beastRunN). It
respects -Dbeast.iters so you can control the number of executions
Things still to address
- this pollutes the task graph and especially if you are running 'gradle
tasks' it gets messy. Probably need to use register instead of create, but
I couldn't make that work with the API.
- I couldn't get them to run in parallel, they were running serially for me
- I didn't get this to accept the standard test selection flags.
Maybe I'll have more time during the week, or maybe somebody else will run
with this.
