Jacoco Maven instrumentation hors ligne - Tomcat

Question

J'essaie d'obtenir un rapport de couverture de code pour les tests d'intégration. Jacoco maven plugin est capable de donner la couverture de code pour les tests unitaires, mais donnant une couverture de 0% pour les tests d'intégration. Les tests d'intégration atteignent les points de terminaison api restants de l'application, qui a été déployée dans tomcat.

Mon plugin jacoco de maven & Le plugin surefire ressemble à ceci.

J'exécute des tests unitaires en phase de test & tests d'intégration en phase de test d'intégration. La dernière erreur que je reçois est «Ignorer l'exécution de JaCoCo en raison d'un fichier de données d'exécution manquant».

Answer 1

Avec l'aide d'Evgeny, j'ai fait ce travail. Le serveur a été changé pour glassfish & ide à intellij pour faciliter le débogage.

Démarrez le serveur glassfish avec les options JVM suivantes.

-DargLine=-javaagent:c:/iat/mavenrepository/org/jacoco/org.jacoco.agent/0.7.9/org.jacoco.agent-0.7.9-runtime.jar=destfile=C:/dmahapat_JaxRsApp/target/coverage-reports/jacoco-it.exec

Answer 2

mentionnant documentation of prepare-agent-integration:

identique à la préparation d'agent, mais fournit des valeurs par défaut adaptées à des tests d'intégration-:

• lié à une pré-integration-test de phase
• différent destfile

Citation documentation of prepare-agent:

Prépare une propriété montrant l'agent d'exécution JaCoCo qui peut être passé comme argument VM à l'application en cours de test. En fonction du type d'emballage de projet par défaut une propriété avec le nom suivant est défini:

• tycho.testArgLine pour le type d'emballage Eclipse test-plugin et
• argLine autrement.

Dans la plupart des cas argLine est automatiquement maven-surefire-plugin ramassé que JVM commence à exécuter des tests unitaires - http://maven.apache.org/surefire/maven-surefire-plugin/test-mojo.html#argLine

argLine: options de JVM arbitraires pour définir la ligne de commande.

Ceci explique pourquoi vous obtenez une couverture pour les tests unitaires. Pour obtenir la couverture des tests d'intégration, vous devez vous assurer que cette propriété est transmise à la JVM de l'application testée, c'est-à-dire JVM qui exécute Tomcat, ce qui dépend entièrement de la façon dont vous le lancez.
