如果单元测试失败，Jenkins脚本化管道不会获取测试结果

Question

我有基于gradle的带有junit测试的Java项目，我正在为其构建CI工作。我使用松弛Slack
Notification插件成功地将松弛与Jenkins集成在一起。

Jenkins版本：2.173
松弛通知版本：2.20

jenkins CI是脚本化管道，具有以下代码：

stage('Test') {
        def slackHelper = new com.xyz.jenkins.libraries.SlackNotifier(env)
        try {
            sh "./gradlew test"
            junit 'build/test-results/test/*.xml'
        } finally {
            AbstractTestResultAction testResultAction =  currentBuild.rawBuild.getAction(AbstractTestResultAction.class)

            slackHelper.getTestStatuses(currentBuild)
            slackSend(channel: '#ci-cd', attachments: slackHelper.buildUnitTestSlackNotificationMessage())
        }
    }

SlackNotifier是一个包含以下代码的库：

/**
 * Calculates test result as a string
 * @param currentBuild : jenkins object, should be passed from jenkins pipeline script
 * @return the final test result as a string
 */
@NonCPS
def getTestStatuses(currentBuild) {
    final AbstractTestResultAction testResultAction = currentBuild.rawBuild.getAction(AbstractTestResultAction.class)
    if (testResultAction != null) {
        this.total = testResultAction.totalCount
        this.failed = testResultAction.failCount
        this.skipped = testResultAction.skipCount
        this.passed = total - failed - skipped
    }
}

buildUnitTestSlackNotificationMessage在同一类中执行此操作：

def buildUnitTestSlackNotificationMessage() {
        final JSONObject unitTestResult = new JSONObject()
        unitTestResult.put("fallback", this.jenkinsEnvironment.JOB_NAME + "with build#" + this.jenkinsEnvironment.BUILD_NUMBER + "finish with unit test result : Passed: " + this.passed + " | Failed: " + this.failed + " | Skipped: " + this.skipped )
        unitTestResult.put("color", this.getUnitTestReportColor())
        unitTestResult.put("pretext", "Message from CI job: " + this.jenkinsEnvironment.JOB_NAME + "#" + this.jenkinsEnvironment.BUILD_NUMBER)
        unitTestResult.put("title", "BuildLog")
        unitTestResult.put("title_link", "<<<JenkinsHost>>>" + this.jenkinsEnvironment.JOB_NAME + "/" + this.jenkinsEnvironment.BUILD_NUMBER  + "/console")
        unitTestResult.put("text", "Passed: " + this.passed +  " | Failed: " + this.failed + " | Skipped: " + this.skipped)
        unitTestResult.put("image_url", this.getLogoURL())
        this.attachments.add(unitTestResult)
        return this.attachments.toString()
    }

所有测试通过后，一切都很好。但是当测试失败时，我会收到以下通知：

Message from CI job: <<<JobName>>>#47
BuildLog
Passed: null | Failed: null | Skipped: null

testResultAction当任何单元测试在此处失败时，结果为null。

我无法深入探讨这一点。请帮忙。

我在reddit中得到了答案，功劳归于：/ u / Bodumin

这是根本原因，我在这里引用他：

Move the junit step into the finally. What's likely happening is that test returns a non 0 (error) status so it fails it of the try.

因此，脚本化管道如下所示：

stage('Test') {
        def slackHelper = new com.xyz.jenkins.libraries.SlackNotifier(env)
        try {
            sh "./gradlew test"
        } finally {
            junit 'build/test-results/test/*.xml'
            AbstractTestResultAction testResultAction =  currentBuild.rawBuild.getAction(AbstractTestResultAction.class)

            slackHelper.getTestStatuses(currentBuild)
            slackSend(channel: '#ci-cd', attachments: slackHelper.buildUnitTestSlackNotificationMessage())
        }
    }
