groovy - 根据 Spock 中的参数模拟方法

Question

我试图找出模拟，出于某种原因它一直返回正确答案 (win) 而不是我希望它返回的答案 (mac)

/**
 * This is an empty imple class.  Its intention is to allow operating
 * system specific information to be mocked for unit testing.
 */
class OsImpl extends Os {

}


/**
 * A utility convenience class that helps with pulling a variety of machine information for the build system
 */
class ProjectInfo {
    static String operatingSystem(){
        operatingSystem(new OsImpl())
    }
    /**
     * Returns a 3 char code on the operating system of the local machine.
     * @return String Code ['win', 'mac', 'nix']
     */
    static String operatingSystem(OsImpl os){
        if (os.isFamily(os.FAMILY_WINDOWS)) {
            'win'
        } else if (os.isFamily(os.FAMILY_MAC)) {
            'mac'
        } else if (os.isFamily(os.FAMILY_UNIX)) {
            'nix'
        } else {
            null
        }
    }
}

class ProjectInfoTest extends Specification {

    def "trying this out"(){
        when:
        OsImpl os = Mock(OsImpl)

        and: 'mock a mac'
        1 * os.isFamily(os.FAMILY_WINDOWS) >> false
        1 * os.isFamily(os.FAMILY_MAC) >> true

        then: 'should return a mac os'
        ProjectInfo.operatingSystem(os) == 'mac'
    }
}

在 easymock 中，我通常会做一个 when(...).return(...) 但我不确定如何用 spock 做同样的事情。

第二次尝试

def "trying this out"(){
        setup:
        OsImpl os = Mock(OsImpl)
        1 * os.isFamily(os.FAMILY_WINDOWS) >> false
        1 * os.isFamily(os.FAMILY_MAC) >> true

        when:
        String shouldBe = 'mac'

        then: 'should return a mac os'
        ProjectInfo.operatingSystem(os) == shouldBe
    }

仍然返回 windows，而不是 mac

这是另一个例子。我想我只是不擅长 mock 。但这是我要测试的方法

def switchArtifactoryOffline(){
    def config = new XmlSlurper().parseText( artifactoryClient.system().configuration())
    if (config.offlineMode == false){
        config.offlineMode = true
        artifactoryClient.system().configuration(XmlUtil.serialize( config ))
    }
    log.lifecycle("Disabled Artifactory Internet Access")
}

和我的测试方法

def "check that it switches artifactory offline"(){
    when:
    Artifactory arti = Mock(Artifactory)
    arti.system().configuration() >> "<client><offlineMode>false</offlineMode></client>"
    ArtifactoryWorker worker = new ArtifactoryWorker(arti)

    then:
    worker.switchArtifactoryOffline()
}

我一直在 system() 对象上得到一个空值。现在，除了模拟它之外，我如何检索该方法放入 artifactoryClient.system().configuration(XmlUtil.serialize( config )) 的值，以便我可以确保它实际上是否更改了值并正确编译了 xml？这对我来说似乎都是微不足道的事情，我不明白为什么我会遇到这样的问题。也许我确实需要切换回 mockito。

好吧，经过更多的折腾之后，我想出了这个，它似乎有效，现在回到静态......

def "check that it switches artifactory offline"(){
    given:
    Artifactory arti = Mock(Artifactory)
    ArtifactorySystem arti_system = Mock(ArtifactorySystem)

    arti_system.configuration() >> "<client><offlineMode>false</offlineMode></client>"
    arti.system() >> arti_system

    ArtifactoryWorker worker = new ArtifactoryWorker(arti)

    when:
    worker.switchArtifactoryOffline()

    then:
    1 * arti_system.configuration(_ as String) >> {
        def config = new XmlSlurper().parseText(it)
        assert config.offlineMode == true
    }
}

Answer 1

将模拟语句向下移动到“then:” block 中。只是让它们高于断言。 “和:”是让你绊倒的原因。模拟标注属于“setup/given” block 或“then” block 。

像这样:

def "trying this out"(){
    setup:
    OsImpl os = Mock(OsImpl)

    expect: 'should return a mac os'
    1 * os.isFamily(os.FAMILY_WINDOWS) >> false
    1 * os.isFamily(os.FAMILY_MAC) >> true

    ProjectInfo.operatingSystem(os) == 'mac'
}
