Gradle configuration Spring multi-project test

 For projects with multiple Gradle projects, if the main project is executing unit test, other sub-projects will be executed together, and some advanced settings are required.

First refer to another article, use eclipse to configure two SpringBoot projects: lab-springboot, library1.

Gradle references the level project

First, modify the build.gradle of library1 and add these codes at the bottom of the file:

configurations {
    // Gradle DSL
    // The names of the configurations which this configuration extends from.
    testOutput.extendsFrom (testImplementation)
}

task jarTest (type: Jar, dependsOn: testClasses) {
    from sourceSets.test.output
    classifier = 'test'
 // The classifier distinguishes different artifacts build from the same project.
}

artifacts {
    testOutput jarTest
}

Then modify the build.gradle of lab-springboot and add these codes at the bottom of the file. Note that there may be other codes in the dependencies:

dependencies {
        implementation project(':library1')
	testImplementation project(path: ':library1', configuration: 'testOutput')
}

test {
	useJUnitPlatform()
}

After the configuration is complete, enter the lab-springboot directory, and you can enter the command:

gradle test -i

It can be observed that in addition to the unit test of lab-springboot, the unit test of library1 is also executed.
