Best approach for triggering afterEvaluate hooks within unit tests

test-tag
plugins

(Eric Deandrea) #1

When writing unit tests via the ProjectBuilder we need to trigger afterEvaluate blocks within our plugins to be able to properly test the resulting configuration that the plugins did. I’ve been playing with doing

def runProjectAfterEvaluate(Project project) {
  project.projectEvaluationBroadcaster.afterEvaluate project, new ProjectStateInternal()
}

But that is causing other exceptions, namely

Caused by: org.gradle.api.ProjectConfigurationException: A problem occurred configuring root project 'MyPlugin'.

Any ideas on how to accomplish what I’m trying to do?

Not sure if this is the best solution, but I found if I do this then it seems to work…

def runProjectBeforeEvaluate(Project project) {
  project.projectEvaluationBroadcaster.beforeEvaluate project
}

def runProjectAfterEvaluate(Project project) {
  runProjectBeforeEvaluate project
  project.state.executing = true
  project.projectEvaluationBroadcaster.afterEvaluate project, project.state
}
