Jenkins:方法存根根据平台失败

Question

下面是我编写的一段(简化的)代码和相关的单元测试，直到最近我都很高兴。

文件vars/删除File.groovy

@NonCPS
def call(String path) {
    new File(path).delete() //Must be declared as authorized class & method in Jenkins
}

文件vars/to.groovy：

def call(Map params = [:] ) {
...
    deleteFile(params.get('envFile'))
...
}

文件测试/vars/TotoSpec.groovy：

class TotoSpec extends JenkinsPipelineSpecification {

    def toto = null

    def setup() {
        toto = loadPipelineScriptForTest('vars/toto.groovy')
        ...
    }

    def '[toto] test env file'() {
        when:
        toto envFile: 'env.list'

        then:
        ...
        1 * getPipelineMock('deleteFile.call').call('env.list')
    }

}

这个测试过去在我的本地机器和CI从机上都能通过。但是，我不知道为什么，这开始在我的本地机器(但不是在奴隶上)上失败：

java.lang.IllegalStateException: 
There is no pipeline step mock for [deleteFile.call].
        1. Is the name correct?
        2. Does the pipeline step have a descriptor with that name?
        3. Does that step come from a plugin? If so, is that plugin listed as a dependency in your pom.xml?
        4. If not, you may need to call explicitlyMockPipelineStep('deleteFile.call') in your test's setup: block.
        at TotoSpec.[toto] test env file(TotoSpec.groovy:90)

因此，我在我的单元测试上执行了下面的更新，但是我不确定deleteFile是否真的是一个管道步骤，因为它没有body/闭包。

文件测试/vars/TotoSpec.groovy：

class TotoSpec extends JenkinsPipelineSpecification {

    def setup() {
        toto = loadPipelineScriptForTest('vars/toto.groovy')
        explicitlyMockPipelineStep('deleteFile')
        ...
    }

    def '[toto] test env file'() {
        when:
        toto envFile: 'env.list'

        then:
        ...
        1 * getPipelineMock('deleteFile').call('env.list')
    }

}

现在，单元测试在我的本地机器上是正常的，但是在CI从服务器上失败：

org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object 'Mock Generator for [deleteFile]' with class 'com.homeaway.devtools.jenkins.testing.PipelineVariableImpersonator' to class 'groovy.lang.Closure'
    at TotoSpec.setup(TotoSpec.groovy:32)

我错过了什么？

Answer 1

再次仔细阅读文档之后，由于deleteFile是自己在vars目录中声明的，因此它被视为管道共享库全局变量。

因此，现在切换到以下单元测试在任何地方都是正确的：

class TotoSpec extends JenkinsPipelineSpecification {

    def setup() {
        toto = loadPipelineScriptForTest('vars/toto.groovy')
        explicitlyMockPipelineVariable('deleteFile')
        ...
    }

    def '[toto] test env file'() {
        when:
        toto envFile: 'env.list'

        then:
        ...
        1 * getPipelineMock('deleteFile.call').call('env.list')
    }
}

但是，目前还不清楚为什么我突然需要在我的机器上使用explicitlyMockPipelineVariable('deleteFile')。
