How to create a Gradle Task to run only a specific Tests in Spring - spring

Question

I have a Spring Project where I wrote some Unit and Integration Tests. Now I want to create custom tasks for running all unit tests, all integration tests and one task for running both. But how can I do this?

Answer 1

I would suggest separating integration tests into separate source set. By default you already have 2 source sets, one for production code and one for tests. To create a new source set (create new directory under src/integrationTest/java) and add a following configuration using Junit5:
test {
useJUnitPlatform()
}
sourceSets {
integrationTest {
java.srcDir file("src/integrationTest/java")
resources.srcDir file("src/integrationTest/resources")
compileClasspath += sourceSets.main.output + configurations.testRuntime
runtimeClasspath += output + compileClasspath
}
}
For separate task:
task integrationTest(type: Test) {
description = 'Runs the integration tests.'
group = 'verification'
testClassesDirs = sourceSets.integrationTest.output.classesDirs
classpath = sourceSets.integrationTest.runtimeClasspath
useJUnitPlatform()
reports {
html.enabled true
junitXml.enabled = true
}
}
Now you have 3 tasks available:
gradlew test
gradlew integrationTest
gradlew check - runs both as it depends on Test task which both extend
If you also are using jacoco and want to merge the test results then you can have following tasks:
task coverageMerge(type: JacocoMerge) {
destinationFile file("${rootProject.buildDir}/jacoco/test.exec")
executionData fileTree(project.rootDir.absolutePath).include("**/build/jacoco/*.exec")
}
// aggregate all coverage data at root level
if (tasks.findByName("test")) {
tasks.findByName("test").finalizedBy coverageMerge
}
if (tasks.findByName("integrationTest")) {
tasks.findByName("integrationTest").finalizedBy coverageMerge
}
task codeCoverageReport(type: JacocoReport) {
executionData fileTree(project.rootDir.absolutePath).include("**/build/jacoco/*.exec")
subprojects.each {
if (!it.name.contains('generated')) {
sourceSets it.sourceSets.main
}
}
reports {
xml.enabled true
html.enabled true
html.setDestination(new File("${buildDir}/reports/jacoco"))
csv.enabled false
}
}
To run coverage report just execute
gradlew codeCoverageReport
