提供者契约测试与 Git 中的桩

在此流程中，我们执行提供者契约测试（生产者并不了解消费者如何使用其API）。存根被上传到一个独立的仓库（它们不会上传至Artifactory或Nexus）。spring-doc.cadn.net.cn

前置条件

在使用 git 中的存根测试提供者契约之前，您必须提供一个包含每个生产者所有存根的 git 仓库。有关此类项目的示例，请参见此示例或此示例。将存根推送到该仓库后，仓库将具有以下结构：spring-doc.cadn.net.cn

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

您还必须提供已配置 Spring Cloud Contract Stub Runner 的消费者代码。有关此类项目的示例，请参见此示例，并搜索包含 BeerControllerGitTest 的测试。您还必须提供已配置 Spring Cloud Contract 的生产者代码，以及相应的插件。有关此类项目的示例，请参见此示例。spring-doc.cadn.net.cn

流程

流程与开发您的第一个基于 Spring Cloud Contract 的应用程序中所展示的完全一致，但 Stub Storage 的实现是一个 Git 仓库。spring-doc.cadn.net.cn

您可以阅读更多关于设置 git 仓库以及设置消费者端和生产者端的信息，详见文档中的《如何操作》页面。spring-doc.cadn.net.cn

消费者设置

为了从 Git 仓库而非 Nexus 或 Artifactory 获取存根（stubs），您需要在 Stub Runner 的 repositoryRoot 属性的 URL 中使用 git 协议。以下示例展示了如何进行配置：spring-doc.cadn.net.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);

设置生产者

要将存根推送到 Git 仓库而非 Nexus 或 Artifactory，您需要在插件设置的 URL 中使用 git 协议。此外，您还需显式告知插件在构建过程结束时推送存根。以下示例分别展示了如何在 Maven 和 Gradle 中实现此操作：spring-doc.cadn.net.cn

Maven

<plugin>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-contract-maven-plugin</artifactId>
    <version>${spring-cloud-contract.version}</version>
    <extensions>true</extensions>
    <configuration>
        <!-- Base class mappings etc. -->

        <!-- We want to pick contracts from a Git repository -->
        <contractsRepositoryUrl>git://git://[email protected]:spring-cloud-samples/spring-cloud-contract-nodejs-contracts-git.git</contractsRepositoryUrl>

        <!-- We reuse the contract dependency section to set up the path
        to the folder that contains the contract definitions. In our case the
        path will be /groupId/artifactId/version/contracts -->
        <contractDependency>
            <groupId>${project.groupId}</groupId>
            <artifactId>${project.artifactId}</artifactId>
            <version>${project.version}</version>
        </contractDependency>

        <!-- The contracts mode can't be classpath -->
        <contractsMode>REMOTE</contractsMode>
    </configuration>
    <executions>
        <execution>
            <phase>package</phase>
            <goals>
                <!-- By default we will not push the stubs back to SCM,
                you have to explicitly add it as a goal -->
                <goal>pushStubsToScm</goal>
            </goals>
        </execution>
    </executions>
</plugin>

Gradle

contracts {
	// We want to pick contracts from a Git repository
	contractDependency {
		stringNotation = "${project.group}:${project.name}:${project.version}"
	}
	/*
	We reuse the contract dependency section to set up the path
	to the folder that contains the contract definitions. In our case the
	path will be /groupId/artifactId/version/contracts
	 */
	contractRepository {
		repositoryUrl = "git://git://[email protected]:spring-cloud-samples/spring-cloud-contract-nodejs-contracts-git.git"
	}
	// The mode can't be classpath
	contractsMode = "REMOTE"
	// Base class mappings etc.
}

/*
In this scenario we want to publish stubs to SCM whenever
the `publish` task is run
*/
publish.dependsOn("publishStubsToScm")
