问题：

Gradle test task testReport task-不推荐使用Gradle 2.3/Java7或Java8的属性

戈宏义

2023-03-14

我正在尝试我的项目从java7改为Java8。因此，我对gradle 1.6中使用的现有gradle extra.commons-myp.gradle脚本进行了修改。


    testReportDir = file("$buildDir/reports/tests/UT")
    testResultsDir = file("$buildDir/test-results/UT")

请告诉我我缺少什么。..


    allprojects {
       apply plugin: 'java' 
       apply plugin: 'jacoco'

        tasks.withType(Compile) {
         options.debug = true
         options.compilerArgs = ["-g"]
       }

       sourceSets {
          main {
             java {
                srcDir 'dont_change_me'
             }
             resources {
                srcDir 'dont_change_me'
             }
          }
          test {
             java {
                srcDir 'dont_change_me'
             }
             resources {
                srcDir 'dont_change_me'
             }
          }

             }
             resources {
                srcDir 'dont_change_me'
             }
          }

       }

       jacoco {
            toolVersion = "0.7.2.201409121644"
       }

       test {
         maxParallelForks = 5
         forkEvery = 50
         ignoreFailures = true

         testReportDir = file("$buildDir/reports/tests/UT")
         testResultsDir = file("$buildDir/test-results/UT")

         }

         //Following Jacoco test section is required only in Jenkins instance extra common file

         ignoreFailures = true

         testClassesDir = sourceSets.integrationTest.output.classesDir
         classpath = sourceSets.integrationTest.runtimeClasspath

         testReportDir = file("$buildDir/reports/tests/IT")
         testResultsDir = file("$buildDir/test-results/IT")

         ignoreFailures = true

         testClassesDir = sourceSets.integrationTest.output.classesDir
         classpath = sourceSets.integrationTest.runtimeClasspath

         testReportDir = file("$buildDir/reports/tests/AT")
         testResultsDir = file("$buildDir/test-results/AT")

         //Following Jacoco test section is required only in Jenkins instance extra common file
         jacoco {        
           destinationFile = file("$buildDir/jacoco/AT/jacocoAT.exec")
           classDumpFile = file("$buildDir/jacoco/AT/classpathdumps")
         }
      }

      jacocoTestReport {
          group = "Reporting"
          description = "Generate Jacoco coverage reports after running tests."
          ignoreFailures = true
          executionData = fileTree(dir: 'build/jacoco', include: '**/*.exec')

          reports {
                 xml{
                     enabled true
                     //Following value is a file
                     destination "${buildDir}/reports/jacoco/xml/jacoco.xml"
                 }
                 csv.enabled false
                 html{
                     enabled true
                     //Following value is a folder
                     destination "${buildDir}/reports/jacoco/html"
                 }
          }     
          sourceDirectories = files('src/java')
          classDirectories =  files('build/classes/main')
      }
    }

对于这两个属性中的任何一个,您得到的错误与下面的错误相似：

No such property: testResultDirs for class: org.gradle.api.tasks.testing.Test_Decorated

好吧。

在Gradle1.6或直到1.10之前（我猜），以下属性可用于测试任务。

testReportDir = file("$buildDir/reports/tests/UT")
testResultsDir = file("$buildDir/test-results/UT")

如您所见，第一个属性创建了一个自定义报表文件夹（HTML index.HTML文件将被放置在其中，即，我们希望将index.HTML/和其他文件放在build/reports/tests/ut文件夹下，而不是使用默认的build/reports/tests/ut文件夹下的该文件旁边），第二个属性创建了自定义测试结果文件夹（即，不是使用build/test-results文件夹来放置单元测试结果*.xml文件/文件夹，而是现在将所有数据放入build/test-results/ut文件夹）。

这个想法是：在Gradle1.6中，Gradle正在创建测试结果（.xml等）/报告文件（.html等），当您刚刚运行：Gradle clean build（作为测试任务，免费运行，即build调用测试任务来运行单元测试，而不需要用户显式调用测试任务）。

现在，当您使用Gradle1.6<1.9/10的Java7时，事情是好的，但是当您开始使用Java8时，您可能会看到Gradle1.6与Java8不兼容的问题（由于ASM库和使用Java8时出现的其他编译时问题），因此您从使用Gradle1.6跳到了Gradle2.3版本。

PS：Gradle2.4是最新的一个，但是它需要在额外的全局（init.d级别）Gradle文件中进行额外的调整。我会说坚持2.3级。

现在，到您的？s-如何获得自定义测试结果和报表文件夹（创建的build/test-results/ut和build/reports/tests/ut文件夹）。

此时，您将Java8与Gradle2.3一起使用（或与Java7)。重要的是现在你的等级是2.3级（而不是1.6级）。

那么，改什么，怎么找改什么。

对于ex:https://docs.gradle.org/2.3/dsl/org.gradle.api.tasks.testing.test.html只显示您可以在测试任务中设置的主要属性或变量。

幸运的是，现在测试任务中不再有testReportDir或testResultsDir属性可用（在Gradle 2.3中）。

看看所有Gradle都能看到什么。请参阅或运行：gradle properties

 test {
 ...
 .....
 reports.html.enabled = false
 ...
 .
 }

参见以下示例:https://docs.gradle.org/2.3/userguide/java_plugin.html#sec:java_test，参见第23.13.7节和示例：23.14。

subprojects {
    apply plugin: 'java'

    // Disable the test report for the individual test task
    test {
        reports.html.enabled = false
    }
}

task testReport(type: TestReport) {
    destinationDir = file("$buildDir/reports/allTests")
    // Include the results from the `test` task in all subprojects
    reportOn subprojects*.test
}

上面的示例显示，它将在读取多模块项目结构中所有子项目的测试结果（.xml/etc信息）后创建测试报告(HTML)，并在build/tests/alltests文件夹中创建结果报告。

现在，我们没有多模块结构，所以我们必须做以下工作:1。在Extra1中添加新任务testReport...init.d级分级文件。

task testReport(type: TestReport) {
    destinationDir = file("$buildDir/reports/tests/UT")
    testResultDirs = fileTree("$buildDir/test-results/UT")
    reportOn test
}

test {
     maxParallelForks = 5
     forkEvery = 50
     ignoreFailures = true
     //The following two properties DONT work in Gradle 2.3
     //testReportDir = file("$buildDir/reports/tests/UT")
     //testResultsDir = file("$buildDir/test-results/UT")

     //With Gradle 2.3 we now need the following line to disable HTML report creation during test run per project/sub-project as we'll take care of generating those reports by testReport task which is available in Gradle 2.3.
     reports.html.enabled = false

     //OK - it took some time, but finally I can change the test-results
     //folder which Gradle generates and uses it to put the .xml/tests results files and etc folders.
     //As there is NO way to set a property in Gradle 2.3 to change the result directory property/variable, 
     //the only way we can do it by adding the following line.
     testResultsDirName = "test-results/UT"

     //The following commented out lines are optional. Un-comment if you need to.
     //testLogging.showStandardStreams = true

     //onOutput { descriptor, event ->
     //    logger.lifecycle("Test: " + descriptor + " produced standard out/err: " + event.message )
     //}

     //Following Jacoco test section is required only in Jenkins instance extra common file
     jacoco {
        //Following two properties/variables works ONLY with 1.6 of Gradle
        //destPath = file("$buildDir/jacoco/UT/jacocoUT.exec")
        //classDumpPath = file("$buildDir/jacoco/UT/classpathdumps")


        //Following two properties/variable works only with versions >= 1.7 version of Gradle
        destinationFile = file("$buildDir/jacoco/UT/jacocoUT.exec")
        //  classDumpFile = file("$buildDir/jacoco/UT/classpathdumps")
     }

     //Usually one should call testReport at command line while calling gradle clean build 
     // i.e. gradle clean build testReport
     // But using Gradle 2.3 finalizedBy feature, you can call testReport as soon as test task is run by Gradle during gradle clean build.
     // PS: This will bring confusion if you have a multi-module project structure as there, you should call testReport task explicitly at command line. So, comment or uncomment acc. to your use.
     finalizedBy testReport
   }

如果您注意到，有一些变量从Gradle1.6到Gradle2.3，从一个任务到另一个任务，这些变量/属性的名称也做了一些更改（例如：TestResultDir到testResultDirs)，并且test task中不再有testReportDir属性，但testReport任务中现在有了destinationDir。

此外，我在测试任务完成后调用testReport任务（作为test.FinalizedBy testReport）来自动调用testReport任务（而不是要求用户显式调用它）。

另一个变通方法是，如果您不需要进行上述更改（以获得您试图实现的目标），并且也不希望在结束时运行testReport任务来运行报表，那么您也可以执行以下操作。仔细观察这次被取消评论/评论的内容。

//task testReport(type: TestReport) {
//    destinationDir = file("$buildDir/reports/tests/UT")
//    testResultDirs = fileTree("$buildDir/test-results/UT")
//    reportOn test
//}

test {
     maxParallelForks = 5
     forkEvery = 50
     ignoreFailures = true
     //The following two properties DONT work in Gradle 2.3
     //testReportDir = file("$buildDir/reports/tests/UT")
     //testResultsDir = file("$buildDir/test-results/UT")

     //With Gradle 2.3 we now need the following line to disable HTML report creation during test run per project/sub-project as we'll take care of generating those reports by testReport task which is available in Gradle 2.3.
     //This time you need to comment the following line, so that it'll actually create the reports/html file during test run.
     //reports.html.enabled = false

     doFirst {   
     //OK - it took some time, but finally I can change the test-results
     //folder which Gradle generates and uses it to put the .xml/tests results files and etc folders.
     //As there is NO way to set a property in Gradle 2.3 to change the result directory property/variable, 
     //the only way we can do it by adding the following line.
     testResultsDirName = "test-results/UT"

     //Add the following if reports.html.enable = false line is commented out OR it's not commented but value is set to "true".
     //The following line will change the default build/reports/tests folder to build/reports/tests/UT for creating html reports for Unit tests.
     testReportDirName = "tests/UT"
     }

     //The following commented out lines are optional. Un-comment if you need to.
     //testLogging.showStandardStreams = true

     //onOutput { descriptor, event ->
     //    logger.lifecycle("Test: " + descriptor + " produced standard out/err: " + event.message )
     //}

     //Following Jacoco test section is required only in Jenkins instance extra common file
     jacoco {
        //Following two properties/variables works ONLY with 1.6 of Gradle
        //destPath = file("$buildDir/jacoco/UT/jacocoUT.exec")
        //classDumpPath = file("$buildDir/jacoco/UT/classpathdumps")


        //Following two properties/variable works only with versions >= 1.7 version of Gradle
        destinationFile = file("$buildDir/jacoco/UT/jacocoUT.exec")
        //  classDumpFile = file("$buildDir/jacoco/UT/classpathdumps")
     }

     //Usually one should call testReport at command line while calling gradle clean build 
     // i.e. gradle clean build testReport
     // But using Gradle 2.3 finalizedBy feature, you can call testReport as soon as test task is run by Gradle during gradle clean build.
     // PS: This will bring confusion if you have a multi-module project structure as there, you should call testReport task explicitly at command line. So, comment or uncomment acc. to your use.

    //Now we don't need to call "gradle clean build testReport" anymore. 
    //finalizedBy testReport
   }

正如您在上面的代码中所注意到的：1。现在我的全局init.d级分级文件甚至没有testReport任务。2.我已经把这一行注释掉了：

//reports.html.enabled = false

3.我添加了另一个属性：testReportDirName=“tests/ut”。

testReportDirName = "tests/UTnew"

PS：在doFirst{..}节/包装器中添加testReportDirName和testResultsDirName很重要（否则，如果您对integrationTest或任何集成测试任务做了类似的更改，那么您的UT文件夹将在build/tests-results/it文件夹内创建为build/tests-results/it/tests-results/UT文件夹，无论何时运行gradle clean Build；gradle integrationTest（前提是您已启动/运行Tomcat）并再次gradle clean Build。4.在gradle文档中的任何地方都没有关于在测试任务中使用或

好的。提示-提示-你将如何改变它来做同样的事情（为它生成结果/报告文件（Integration Test，又名integrationTest任务）或acceptanceTest任务等），我将留给你去了解。

我用上面的两种方法进行了测试。并成功生成了build/test-results/ut文件夹下的.xml文件和build/reports/tests/ut文件夹下的reports/html文件。
