测试前如何更新 Jenkins 实例？

Question

我正在使用Jenkins作业DSL创建我的作业，并使用Spock和jenkins-test-harness测试我的脚本。

基于Gradle示例，我能够成功安装新的插件，但如何更新已经安装的插件？

我尝试使用UpdateCenter，但即使使用LinkedBlockingQueue，我也无法强制测试等待更新过程。

import groovy.io.FileType
import hudson.PluginWrapper
import hudson.model.UpdateCenter
import javaposse.jobdsl.dsl.DslScriptLoader
import javaposse.jobdsl.dsl.JobManagement
import javaposse.jobdsl.plugin.JenkinsJobManagement
import org.junit.ClassRule
import org.jvnet.hudson.test.JenkinsRule
import spock.lang.Shared
import spock.lang.Specification
import spock.lang.Unroll

import java.util.concurrent.Future
import java.util.concurrent.LinkedBlockingQueue

/**
 * Tests that all dsl scripts in the jobs directory will compile.
 */
class JobScriptsSpec extends Specification {
    @Shared
    @ClassRule
    JenkinsRule jenkinsRule = new JenkinsRule()

    def setupSpec() {
        printPlugins()
        jenkinsRule.getInstance().getUpdateCenter().updateAllSites()
        def plugin = jenkinsRule.getInstance().getUpdateCenter().getPlugin('subversion')
        println "Wait for subversion update..."
        def queue = new LinkedBlockingQueue<Future<UpdateCenter>>()
        queue.add(plugin.deploy())
        queue.take()
        println "Wait Done..."
    }

    @Unroll
    void 'test script #file.name'(File file) {
        given:

        JobManagement jm = new JenkinsJobManagement(System.out, [:], new File('.'))

        when:
        new DslScriptLoader(jm).runScript(file.text)

        then:
        noExceptionThrown()

        where:
        file << jobFiles
    }

    private void printPlugins() {
        println "****** Plugins *****"
        List<PluginWrapper> plugins = jenkinsRule.getPluginManager().getPlugins()
        plugins.each { PluginWrapper plugin ->
            println "Plugin: ${plugin.getLongName()}"
        }
    }

    static List<File> getJobFiles() {
        List<File> files = []
        new File('jobs').eachFileRecurse(FileType.FILES) {
            if (it.name.endsWith('.groovy')) {
                files << it
            }
        }
        files
    }
}

您可以将任何要安装或更新的插件添加到 build.gradle 文件中的 testPlugins 配置中：

dependencies {
  // ...
  testPlugins 'org.jenkins-ci.plugins:subversion:2.6'
  // ...
}
