testing - gradle beforeSuite {}和afterSuite {}执行多次

Question

今天我遇到了一个问题，与Gradle中的beforeSuite{}和afterSuite{}有关。我在gradle 4.1的测试任务中添加了beforeSuite{}和afterSuite{}，但是每次执行测试时，它都会多次运行闭包。我想我已经使用-debug将其范围缩小到了为单个任务生成的多个任务 Action 。

build.gradle:

task unzipfirefoxDriver(type: Copy) {
    //https://github.com/mozilla/geckodriver/releases
    def outputDir = file("$buildDir/webdriver/geckodriver")
    outputs.dir(outputDir)
    if (OperatingSystem.current().isWindows()) {
        from(zipTree("drivers/geckodriver-${gechoVersion}-win64.zip"))
    } else {
        from(tarTree("drivers/geckodriver-${gechoVersion}-macos.tar.gz"))
    }
    into(outputDir)
    def geckodriverFilename = OperatingSystem.current().isWindows() ? "geckodriver.exe" : "geckodriver"
    map.put("firefox", new File(outputs.files.singleFile, geckodriverFilename))

}

task firefoxTest(type: Test) {
    testLogging {
        events 'started', 'passed'
    }
    reports {
        html.destination = reporting.file("$name/tests")
        junitXml.destination = file("$buildDir/test-results/$name")
    }
    beforeSuite { desc ->
        println "Automation has Started"
    }
    afterSuite { desc, result ->
        println "Automation has Finished - Results: ${result.resultType} (${result.testCount} tests, ${result.successfulTestCount} successes, 
${result.failedTestCount} failures, ${result.skippedTestCount} skipped)"
    }
    outputs.upToDateWhen { false }
    systemProperty("webdriver.gecko.driver", map."firefox".absolutePath)
    systemProperty("geb.env", "firefox")
}
firefoxTest.dependsOn unzipfirefoxDriver

在gradle中，需要调用beforeSuite和afterSuite。修改闭包以检查父级为空以找到根套件:

beforeSuite { descriptor, result ->
    if(descriptor.parent == null){
        //your logic
    }
}
