gradle jacocoTestReport is not working? - gradle

Question

I have tried to get code coverage in a spring-gradle project using gradle jacoco plugin.
The build.gradle contains the following
apply plugin: "jacoco"
jacoco {
toolVersion = "0.7.1.201405082137"
reportsDir = file("$buildDir/customJacocoReportDir")
}
jacocoTestReport {
reports {
xml.enabled false
csv.enabled false
html.destination "${buildDir}/jacocoHtml"
}
}
I then ran
gradle test jacocoTestReport
Where after only the file test.exec is generated in build/reports folder.
Other than that nothing happens.
How can I get the HTML report?

Answer 1

You don't have to configure reportsDir/destinationFile
Because jacoco has default values for them.
build.gradle:
plugins {
id 'java'
id 'jacoco'
}
jacocoTestReport {
reports {
xml.enabled true
html.enabled true
csv.enabled true
}
}
repositories {
jcenter()
}
dependencies {
testCompile group: 'junit', name: 'junit', version: '4.12'
}
Run gradle test jacocoTestReport
You can find the test report in ./build/reports/jacoco/test directory.
HTML output is in ./build/reports/jacoco/test/html directory.

Following helped . its in samples/testing/jacaco of gradle-2.3-all.zip from https://gradle.org/releases/
apply plugin: "java"
apply plugin: "jacoco"
jacoco {
toolVersion = "0.7.1.201405082137"
reportsDir = file("$buildDir/customJacocoReportDir")
}
repositories {
mavenCentral()
}
dependencies {
testCompile "junit:junit:4.+"
}
test {
jacoco {
append = false
destinationFile = file("$buildDir/jacoco/jacocoTest.exec")
classDumpFile = file("$buildDir/jacoco/classpathdumps")
}
}
jacocoTestReport {
reports {
xml.enabled false
csv.enabled false
html.destination "${buildDir}/jacocoHtml"
}
}

Unfortunately, none of these answers worked for me.
I had a similar issue.
Only different in not having the exec file generated.
And because of that ,
I found that the jacocoTestReport was simply "skipped".
I got it fixed by adding :
apply plugin: 'jacoco'
test {
useJUnitPlatform()
finalizedBy jacocoTestReport // report is always generated after tests run
}
jacocoTestReport {
...
...
...
...
}
That's because I'm using Junit5 with spring boot 2.X

subprojects {
apply(plugin: 'org.jetbrains.kotlin.jvm')
repositories {
jcenter()
mavenCentral()
}
}
task codeCoverageReport(type: JacocoReport) {
// Gather execution data from all subprojects
executionData fileTree(project.rootDir.absolutePath).include("**/build/jacoco/*.exec")
// Add all relevant sourcesets from the subprojects
subprojects.each {
sourceSets it.sourceSets.main
}
reports {
xml.enabled true
html.enabled true
csv.enabled false
}
}
// always run the tests before generating the report
codeCoverageReport.dependsOn {
subprojects*.test
}
sonarqube {
properties {
property "sonar.projectKey", "your_project_key"
property "sonar.verbose", true
property "sonar.projectName", "Your project name"
property "sonar.coverage.jacoco.xmlReportPaths", "${rootDir}/build/reports/jacoco/codeCoverageReport/codeCoverageReport.xml"
}
}
Command to run test with coverage:
./gradlew codeCoverageReport
./gradlew sonarqube -x test (test is excluded since already run and sonarqube by default executes test)
The second command can be ignored if sonarqube is not being used.
Two things to be noted that made it work:
To make available sourcesets of all modules, looping over subprojects and accumulating sourcesets worked. subprojects.sourceSets.main.allSource.srcDirs did not work.
sonar.jacoco.reportPaths is deprecated. We need to use sonar.coverage.jacoco.xmlReportPaths. Check the documentation here
