在 Git 中使用存根进行提供者协定测试

在这个流程中，我们执行提供者契约测试（生产者不知道消费者如何使用他们的 API）。存根将上传到单独的存储库（它们不会上传到 Artifactory 或 Nexus）。spring-doc.cn

先决条件

在 git 中使用存根测试提供商合同之前，您必须提供 git 存储库，其中包含每个生产者的所有存根。有关此类项目的示例，请参阅此示例或此示例。将存根推送到那里的结果，存储库具有以下结构：spring-doc.cn

$ tree .
└── META-INF
   └── folder.with.group.id.as.its.name
       └── folder-with-artifact-id
           └── folder-with-version
               ├── contractA.groovy
               ├── contractB.yml
               └── contractC.groovy

您还必须提供设置了 Spring Cloud Contract Stub Runner 的使用者代码。为此类项目的示例，请参阅此示例并搜索测试。您还必须提供具有 Spring Cloud 的生产者代码合约设置，以及插件。有关此类项目的示例，请参阅此示例。BeerControllerGitTestspring-doc.cn

流程

该流程看起来与开发第一个基于 Spring Cloud Contract 的应用程序中提供的流程完全相同。但实现是一个 Git 存储库。Stub Storagespring-doc.cn

您可以阅读有关设置 git 存储库和设置 consumer 和 producer 端的更多信息在文档的 How To 页面中。spring-doc.cn

消费者设置

为了从 git 存储库而不是 Nexus 或 Artifactory 获取存根，您需要需要在 Stub Runner 中的属性 URL 中使用协议。以下示例显示了如何设置它：gitrepositoryRootspring-doc.cn

注解

@AutoConfigureStubRunner(
stubsMode = StubRunnerProperties.StubsMode.REMOTE,
		repositoryRoot = "git://[email protected]:spring-cloud-samples/spring-cloud-contract-nodejs-contracts-git.git",
		ids = "com.example:artifact-id:0.0.1")

JUnit 4 规则

@Rule
	public StubRunnerRule rule = new StubRunnerRule()
			.downloadStub("com.example","artifact-id", "0.0.1")
			.repoRoot("git://[email protected]:spring-cloud-samples/spring-cloud-contract-nodejs-contracts-git.git")
			.stubsMode(StubRunnerProperties.StubsMode.REMOTE);

JUnit 5 扩展

@RegisterExtension
	public StubRunnerExtension stubRunnerExtension = new StubRunnerExtension()
			.downloadStub("com.example","artifact-id", "0.0.1")
			.repoRoot("git://[email protected]:spring-cloud-samples/spring-cloud-contract-nodejs-contracts-git.git")
			.stubsMode(StubRunnerProperties.StubsMode.REMOTE);

设置 Producer

要将存根推送到 git 存储库而不是 Nexus 或 Artifactory，您需要以在插件设置的 URL 中使用协议。此外，您需要明确告知用于在构建过程结束时推送存根的插件。以下示例显示如何在 Maven 和 Gradle 中执行此操作：gitspring-doc.cn
