How to run integrations test on a web project from another subproject using gradle

Question

I have a gradle multi project where my war file is built in one subproject and my integrations tests are in a different subproject. I have read that gretty should be able to start a jetty instance to let me run the integrations tests during build, but I can not figure out how to "connect" the gretty integrationTestTask task to the task in my other subproject from where the actual tests will be run.

My project structure looks like this:

root/
    int-test/
        build.gradle
    web/
        build.gradle
    build.gradle
    settings.gradle

File content

root/settings.gradle:

include ':web'
include ':int-test'

root/build.gradle:

apply plugin: 'java'

root/web/build.gradle:

apply plugin: 'war'
apply from: 'https://raw.github.com/akhikhl/gretty/master/pluginScripts/gretty.plugin'

gretty {
    contextPath = '/'
    integrationTestTask = 'intTests'
}

task intTests << {
    println 'This task will run in just the right time'
}

root/int-test/build.gradle:

apply plugin: 'java'

task intTests << {
    println 'All integration testing is done in here'
}

When I run "./gradlew -q intTests", this is the output:

All integration testing is done in here

So, the intTests task in the web project will run in the right moment but the intTests task in the int-test project will run way to early (before the web server has been started). How do I set this up so that the gretty plugin "connects" to the intTests task defined in my int-test project?

Things I have tried: * Setting "integrationTestTask = ':int-test:intTests'" hoping that it would be enough to specify in which subproject gretty should be looking for the correct task. Result - jetty is not even started. * Creating the intTests task in the root build.gradle trying to extend that task in int-test. Result - no difference. * Added a dependsOn(":int-test:intTests") to the intTests task in web project. Result - no difference

Answer 1

First, check if gretty.integrationTestTask = ":int-test:intTests" works. If not, add the following to int-tests/build.gradle:

intTests {
    dependsOn(":web:taskThatStartsTheWebServer")
    finalizedBy(":web:taskThatStopsTheWebServer")
}

(You can find the task names in the Gretty docs or the output of gradle tasks.)

Note that it's task foo { dependsOn "bar" }, not task foo << { dependsOn "bar" }. Recent Gradle versions will detect this mistake and fail the build.
