How do you do it? Testing, integration testing and code coverage

Help/Discuss
1

My goal is to setup a build pipeline as discussed in this movie, and I have been messing about with the first steps.

I have a project with some junit tests (reading/writing xml and stuff like that) and have moved my database tests to an integration test task.

However I am not trying to add Jacoco and have only found ways to run it on either test or integTest task. Is there a way to run it on both or is this not supposed to be used this way?

Currently my gradle.build script looks like this:

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'jacoco'


sourceCompatibility = 1.8
targetCompatibility = 1.8
version = '1.0'
repositories {
    mavenCentral()
}

configurations {
    integrationTestCompile.extendsFrom testCompile
    integrationTestRuntime.extendsFrom testRuntime
}

jacoco {
    toolVersion = "0.7.1.201405082137"
    reportsDir = file("$buildDir/customJacocoReportDir")
}

jacocoTestReport {
    reports {
        xml.enabled false
        csv.enabled false
        html.destination "${buildDir}/jacocoHtml"
    }
}


dependencies {
	compile 'org.apache.poi:poi-ooxml:3.9'
        compile 'javax.mail:mail:1.4.1'
	compile fileTree(dir: 'libs', include: ['sqljdbc4.jar'])
	integrationTestCompile 'junit:junit:4.12'
	testCompile 'junit:junit:4.12'
}

jar {
    manifest {
            attributes 'Implementation-Title': 'Helper Classes',
           'Implementation-Version': version
    }
}

sourceSets {
    integrationTest {
        java {
            compileClasspath += main.output + test.output
            runtimeClasspath += main.output + test.output
            srcDir file('src/integTest/java')
        }
        resources.srcDir file('src/integTest/resources')
    }
}


task integrationTest(type: Test){
	description = 'Run the integration tests.'
	group = 'verification'
	testClassesDir = sourceSets.integrationTest.output.classesDir
	classpath = sourceSets.integrationTest.runtimeClasspath
	
}

task jacocoIntegrationTestReport(type: JacocoReport){
	sourceSets sourceSets.main
	executionData integrationTest
}

I’m also interested in this. I asked a similar question but didn’t get a response

I agree! Source code of the “todo” example project would be a great help to get started with all the gradle scripts and plugins!

Both sourceSets and executionData appear to allow multiple values. Have you tried:

task jacocoReport(type: JacocoReport){
    sourceSets sourceSets.main
    executionData test, integrationTest
}

Assuming that’s what you mean by running both. I’m interpreting that as you want to effectively have the union of the test and integrationTest coverage in a single report.

BTW, untested and just based on the documentation/scan of plugin code.

I have done before integration testing by adding an extra source set and duplicating the all test-related tasks, but these days I just have a separate “integration-testing” module (or more than one, nested under heir projects). I find this cleaner and causes less headaches as you don’t need to do anything special.

The cost is that it complicates the directory structure, but I find myself much searching for classes. When I need to browse classes, I switch to IDEA’s package view anyway.

For coverage, I use Teamcity - it does a good job at injecting the coverage plugin and aggregating the metrics. Again, the driving reason is to simplify the build process.

Thx pledbrook, this did the trick for me. I had tried supplying an array [bla,bla] but that gave errors. Never thought of using it without the brackets!

Maybe you find the nebula.integtest plugin useful for. It does all the wiring for you.
