Run gradle spock test task in parallel - testing

Question

In my build.gradle I have the following test task
task test1(type: Test) {
ignoreFailures true
testLogging {
events 'started', 'passed', 'skipped', 'failed'
exceptionFormat "full"
showStandardStreams = true
afterSuite { desc, result ->
if (!desc.parent) { // will match the outermost suite
failedTest += result.failedTestCount
}
}
}
include "org/company/project/test/Test1.class"
}
task test2(type: Test) {
ignoreFailures true
testLogging {
events 'started', 'passed', 'skipped', 'failed'
exceptionFormat "full"
showStandardStreams = true
afterSuite { desc, result ->
if (!desc.parent) { // will match the outermost suite
failedTest += result.failedTestCount
}
}
}
include "org/company/project/test/Test2.class"
}
I want these 2 tests to run in parallel, currently I use this command to run them ./gradlew cleanTest test1 test2 --info --rerun-tasks command to run them.
I tried --parallel, --max-workers=3 options nothing helped.

Gradle doesn't support running tasks inside the same project in parallel, unless you get a configuration cache hit, but that is an incubating feature and it might not work for you.
Is there any reason why you don't use forking inside the test task (docs)?
test {
maxParallelForks = 3
}
or for all test tasks
tasks.withType(Test) {
maxParallelForks = 3
}
