Jacoco Maven離線設備 - Tomcat

Question

我正在嘗試獲取集成測試的代碼覆蓋率報告。 Jacoco maven插件能夠爲單元測試提供代碼覆蓋率，但是爲集成測試提供0％的覆蓋率。集成測試正在部署在tomcat中的應用程序的終點。

我的maven jacoco插件& surefire插件看起來像這樣。

我執行單元測試，在測試階段中集成測試階段&集成測試。 我得到的最新錯誤是「由於缺少執行數據文件而跳過JaCoCo執行程序」。

Answer 1

在Evgeny的幫助下，我做了這項工作。 將服務器更改爲glassfish & ide to intellij以便於調試。

使用以下JVM選項啓動glassfish服務器。

-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

引用documentation of prepare-agent-integration：

同製備劑，但提供了合適的默認值的集成的測試：

• 結合到預集成測試階段
• 不同destFile

報價documentation of prepare-agent：

準備指向JaCoCo運行劑，可以是如被測一個VM參數傳遞給應用程序傳遞一個屬性。根據默認情況下，項目包裝類型，有下列名稱的屬性設置：

• tycho.testArgLine包裝類型Eclipse的測試插件和
• argLine否則。

在大多數情況下argLine自動由maven-surefire-plugin拾取啓動JVM執行單元測試 - http://maven.apache.org/surefire/maven-surefire-plugin/test-mojo.html#argLine

argLine：任意JVM選項在命令行上設置。

這解釋了爲什麼你會得到單元測試的覆蓋率。

要獲得集成測試的覆蓋範圍，您必須確保將此屬性傳遞給測試中的應用程序的JVM，即執行Tomcat的JVM，完全取決於您啓動它的方式。
