using integration tests with gretty in combination with cobertura

[x12a1f]

Hi,

Now that I've got gretty working with jacoco I'm kind of disappointed with jacoco and I want to give cobertura a try.

I believe this should do the trick:

afterEvaluate {
    tasks.appBeforeIntegrationTest {
        gretty { 
              classPath "${project.buildDir}/instrumented_classes"
        }
    }
}

but it does not seem to work as it adds the instrumented_classes to the end of the classpath. For cobertura to work the instrumented_classes need to be at the front of the classpath (or the default build/classes/main entry removed from the classpath)

Do you have any idea or example on how to get cobertura to work with integration tests?

Hello,

I'm afraid there's no way to do it right now as project.sourceSets.main.output is always added in front of classpath.

The only way I can see to achieve this is to put instrumented classes in sourceSets.main.output (build/main/classes) folder overriding default classes.

Furthermore I've added support for beforeClassPath in gretty-1.2.6-SNAPSHOT:

gretty {
    beforeClassPath "${buildDir}/instrumentedClasses"
}

Thanks. I tried it but it does not seem to be working. When using beforeClassPath it still uses the normal, uninstrumented, code.

Currently I have it working using the following work around:

cobertura {
    // cobertura in the servlet containter started by gretty looks for the datafile in this
    // location. TODO: pass the location of this file to the servlet using system properties
    coverageOutputDatafile = file("$projectDir/cobertura.ser")
    coverageReportDatafile = file("$projectDir/cobertura.ser")
}

afterEvaluate {
    tasks.appBeforeIntegrationTest {
        gretty {
            servletContainer = 'jetty9'

            // add the instrumented classes to the class path
            classPath "${project.buildDir}/instrumented_classes"

            // add the libraries needed by cobertura to the class path
            configurations.cobertura.each {
                classPath it
            }

        }
    }
    .doFirst {
        // move the classes out of the way so gretty can only see the instrumented_classes
        file("${project.buildDir}/classes/main.nope").deleteDir()
        file("${project.buildDir}/classes/main").renameTo("${project.buildDir}/classes/main.nope")
    }
}

afterEvaluate {
    tasks.appAfterIntegrationTest.finalizedBy 'generateCoberturaReport'

    // move the classes back
    tasks.generateCoberturaReport.doFirst {
        file("${project.buildDir}/classes/main.nope").renameTo("${project.buildDir}/classes/main")
    }
}

Nice to hear you found a workaround. I'll take a look again today.

Well, using following configuration I was able to achive success with gretty-1.2.6-SNAPSHOT

buildscript {
  repositories {
    mavenLocal()
    jcenter()
    mavenCentral()
  }
  dependencies {
    classpath "ru.shadam.gretty:gretty:$gretty_version"
    classpath "net.saliman:gradle-cobertura-plugin:2.3.1"
  }
}

repositories {
  mavenLocal()
  jcenter()
  maven { url 'http://oss.jfrog.org/artifactory/oss-snapshot-local' }
}

apply plugin: 'groovy'
apply plugin: 'org.akhikhl.gretty'
apply plugin: 'net.saliman.cobertura'

dependencies {
  compile 'org.webjars:bootstrap:3.2.0'
  compile 'org.webjars:jquery:2.1.1'
  // We use Velocity for example of template processing within the webapp.
  compile 'org.apache.velocity:velocity:1.7'
}

cobertura {
  coverageOutputDatafile = file("$projectDir/cobertura.ser")
  coverageReportDatafile = file("$projectDir/cobertura.ser")
}

afterEvaluate {
  tasks.appBeforeIntegrationTest {
    gretty {
      servletContainer = 'jetty9'

      jvmArgs = ['-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5005']

      beforeClassPath "${project.buildDir}/instrumented_classes/"

      // add the libraries needed by cobertura to the class path
      configurations.cobertura.each {
        classPath it
      }
    }
  }

  tasks.appAfterIntegrationTest.finalizedBy 'coberturaReport'
}

dependencies {
  testCompile "org.codehaus.groovy:groovy-all:$groovy_version"
  testCompile "org.spockframework:spock-core:$spock_version"
  testCompile "org.gebish:geb-spock:$gebVersion"
  testCompile "org.seleniumhq.selenium:selenium-support:$seleniumVersion"
  testCompile "org.seleniumhq.selenium:selenium-firefox-driver:$seleniumVersion"
}

test {
  include '**/Test*.*'
  include '**/*Test.*'
  exclude '**/*IT.*'
}

task integrationTest(type: Test, dependsOn: 'test') {
  outputs.upToDateWhen { false }
  include '**/*IT.*'
  doFirst {
    systemProperty 'geb.build.reportsDir', reporting.file('geb')
  }
}

You should use

maven { url 'http://oss.jfrog.org/artifactory/oss-snapshot-local' }

instead of mavenLocal() to reproduce my build.

Yes, I'm not sure what I did wrong earlier but it works. Many thanks!
