在我们的项目中,我们遇到JaCoCo使用Jenkins或SonarQube进行错误覆盖计算的问题。
这是我们用于Jenkins构建的常用构建脚本的示例:
<property name="demo" location="."/>
<property name="exec_name" value="build1.exec"/>
<import file= "${demo}/buildscripts/common/product_common_ant.xml"/>
<property name="coverage_data" location="\\server\jenkins\jobs\Test-Coverage\coverage_data\JobName"/>
<target name="testrun" depends="compile" description="Execute tests with coverage">
<jacoco:coverage destfile="${cov_res_file}" append="true">
<testng classpathref="testrun_classpath" suitename="UnitTests" failureProperty="testng.failure" verbose="2" outputdir="${test-output}" workingDir="${demo}">
<xmlfileset dir="${test}" includes="builds/unitTests.xml"/>
</testng>
</jacoco:coverage>
<copy file="${test-output}/testng-results.xml" tofile = "${test-output}/unit-test-results.xml"/>
<fail if="testng.failure"/>
<jacoco:coverage destfile="${cov_res_file}" append="true">
<testng classpathref="testrun_classpath" suitename="IntegrationTests" failureProperty="testng.failure" verbose="2" outputdir="${test-output}" workingDir="${demo}">
<xmlfileset dir="${test}" includes="builds/integTests_Build.xml"/>
</testng>
</jacoco:coverage>
<copy file = "${test-output}/testng-results.xml" tofile = "${test-output}/integ-test-results.xml"/>
<fail if="testng.failure"/>
<jacoco:coverage destfile="${cov_res_file}" append="true">
<testng classpathref="testrun_classpath" suitename="BUildGUITests1" failureProperty="testng.failure" verbose="2" outputdir="${test-output}" workingDir="${demo}">
<xmlfileset dir="${test}" includes="builds/funcTests_build_part01.xml"/>
</testng>
</jacoco:coverage>
<copy file = "${test-output}/testng-results.xml" tofile = "${test-output}/gui-test-results.xml"/>
<fail if="testng.failure"/>
</target>
<target name="mergeTestResults" depends="testrun, copyCoverageResults">
<copy file="${buildscripts}/empty-test-results.xml" tofile="${test-output}/testng-merge.xml"/>
<for param="xmlFile">
<path>
<fileset dir="${test-output}" >
<include name="unit-test-results.xml" />
<include name="integ-test-results.xml" />
<include name="gui-test-results.xml" />
</fileset>
</path>
<sequential>
<copy file="${test-output}/testng-merge.xml" toFile="${test-output}/start-merge.xml"/>
<xslt style="${buildscripts}/merge-test-results.xsl"
destdir="${test-output}"
in="${test-output}/start-merge.xml"
out="${test-output}/testng-merge.xml">
<param name="with" expression="@{xmlFile}" />
</xslt>
<delete file="${test-output}/start-merge.xml" />
</sequential>
</for>
</target>
所以有例如在此构建和覆盖数据中运行的3个套件将保存到
中\\server\jenkins\jobs\Test-Coverage\coverage_data\JobName\buildX.exec

我已经完成了编译和构建部分。
当Jenkins或SonarQube运行此脚本时,我们获得的代码覆盖率约为19%,而在Eclipse中本地运行所有测试并使用Eclemma(使用Jacoco)进行合并使我们获得约65%(这是更可靠的结果)。
我们的构建在每次SVN提交时运行,并在每次运行之前进行编译。尽管32位和64位架构都在使用,但所有测试服务器都使用相同的Java版本。
我们在这里做错了什么?
答案 0 :(得分:0)
经过一年多的时间,突然代码覆盖率再次变得正确。很奇怪,很遗憾没有办法找出之前的错误。
