Testing Gradle Plugin That Uses project.gradle.projectsEvaluated - unit-testing

Question

I am trying to test a Gradle plugin that uses the BuildAdapter#ProjectsEvaluated function to allow custom configurations and dependencies to be added to my project. The problem that I'm having is that if I evaluate the project using InternalProject#evaluate in the junit test then the projectsEvaluated function is never called. If I switch to the more robust GradleRunner then I do not appear to have the ability to inspect the project(s) later to actually see if my plugin works. I have provided sample code below that shows a sample plugin and a junit test. Does anyone know how I could test this functionality?
class MyPlugin implements Plugin<Project> {
#Override
void apply(Project project) {
project.extensions.create("myPlugin", MyPluginExtension)
project.gradle.projectsEvaluated {
/*
custom logic that needs to evaluate prior
to gradle adding dependencies to project
*/
}
}
The JUnit is provided below:
class MyPluginPluginTest {
private Project project
#Before
void setup() {
project = ProjectBuilder.builder().build()
project.repositories.mavenCentral()
project.apply plugin: 'java'
project.apply plugin: MyPlugin
}
/*
Test to check whether or not the correct dependency
was added to the project when the plugin was evaluated
*/
#Test
void projectHasCheckerFrameworkDependencies() {
((ProjectInternal) project).evaluate()
Set<File> files = project.configurations.getByName('myPlugin').resolve()
assertNotEquals(0, files.size())
assertTrue(files.any { it.name.endsWith("myDependency-${project.jarName.version}.jar") })
}
}

In order to gain access to the information I required I added the projectsEvaluated closure to the projectExtensions as follows:
class MyPlugin implements Plugin<Project> {
#Override
void apply(Project project) {
project.extensions.create("myPlugin", MyPluginExtension)
def projectsEvaluatedClosure = {
/*
custom logic that needs to evaluate prior
to gradle adding dependencies to project
*/
}
project.extensions.add("myPluginProjectsEvaluatedClosure", projectsEvaluatedClosure)
project.gradle.projectsEvaluated closure
}
}
Now that the projectsEvaluated closure is accessible in the project I executed the closure manually from the test case. This isn't an ideal solution, but I was able to verify that the code was working properly.
