Stub Runner JUnit 规则和 Stub Runner JUnit5 扩展

Stub Runner 附带一个 JUnit 规则,允许您下载和运行给定的 stub group 和工件 ID,如下例所示:spring-doc.cn

@ClassRule
public static StubRunnerRule rule = new StubRunnerRule().repoRoot(repoRoot())
	.stubsMode(StubRunnerProperties.StubsMode.REMOTE)
	.downloadStub("org.springframework.cloud.contract.verifier.stubs", "loanIssuance")
	.downloadStub("org.springframework.cloud.contract.verifier.stubs:fraudDetectionServer");

@BeforeClass
@AfterClass
public static void setupProps() {
	System.clearProperty("stubrunner.repository.root");
	System.clearProperty("stubrunner.classifier");
}

A 也可用于 JUnit 5。 并以非常相似的方式工作。在规则或扩展名 调用,则 Stub Runner 会连接到您的 Maven 存储库,并且对于给定的 依赖项尝试:StubRunnerExtensionStubRunnerRuleStubRunnerExtensionspring-doc.cn

  • 下载spring-doc.cn

  • 在本地缓存它们spring-doc.cn

  • 将它们解压缩到临时文件夹spring-doc.cn

  • 从提供的随机端口为每个 Maven 依赖项启动一个 WireMock 服务器 端口范围或提供的端口spring-doc.cn

  • 向 WireMock 服务器提供所有作为有效 WireMock 定义的 JSON 文件spring-doc.cn

  • 发送消息(记得传递 interface 的实现)MessageVerifierSenderspring-doc.cn

Stub Runner 使用 Eclipse Aether 机制下载 Maven 依赖项。 查看他们的文档以获取更多信息。spring-doc.cn

由于 和 实现 ,他们让 您可以找到 Started Stubs,如下例所示:StubRunnerRuleStubRunnerExtensionStubFinderspring-doc.cn

有关更多信息,请参阅 JUnit 和 Spring 的通用属性 如何应用 Stub Runner 的全局配置。spring-doc.cn

要将 JUnit 规则或 JUnit 5 扩展与消息收发一起使用,您必须为规则生成器提供 and 接口的实现(例如, )。 如果不这样做,则每当尝试发送消息时,都会引发异常。MessageVerifierSenderMessageVerifierReceiverrule.messageVerifierSender(new MyMessageVerifierSender())

Maven 设置

存根下载程序遵循其他本地存储库文件夹的 Maven 设置。 当前不考虑存储库和配置文件的身份验证详细信息。 因此,您需要使用上述属性来指定它。spring-doc.cn

提供固定端口

您还可以在固定端口上运行存根。您可以通过两种不同的方式来实现。 一种是在 properties 中传递,另一种是使用 Fluent API JUnit 规则。spring-doc.cn

Fluent API

使用 or 时,您可以添加要下载的存根 然后传递最后下载的存根的端口。以下示例显示了如何执行此操作:StubRunnerRuleStubRunnerExtensionspring-doc.cn

@ClassRule
public static StubRunnerRule rule = new StubRunnerRule().repoRoot(repoRoot())
	.stubsMode(StubRunnerProperties.StubsMode.REMOTE)
	.downloadStub("org.springframework.cloud.contract.verifier.stubs", "loanIssuance")
	.withPort(35465)
	.downloadStub("org.springframework.cloud.contract.verifier.stubs:fraudDetectionServer:35466");

@BeforeClass
@AfterClass
public static void setupProps() {
	System.clearProperty("stubrunner.repository.root");
	System.clearProperty("stubrunner.classifier");
}

对于前面的示例,以下测试有效:spring-doc.cn

then(rule.findStubUrl("loanIssuance")).isEqualTo(URI.create("http://localhost:35465").toURL());
then(rule.findStubUrl("fraudDetectionServer")).isEqualTo(URI.create("http://localhost:35466").toURL());

Stub Runner with Spring 设置 Stub Runner 项目的 Spring 配置。spring-doc.cn

通过在配置文件中提供存根列表,Stub Runner 会自动下载 并在 WireMock 中注册选定的存根。spring-doc.cn

如果你想找到你的存根依赖项的 URL,你可以自动装配接口并使用 其方法,如下所示:StubFinderspring-doc.cn

这样做取决于以下配置文件:spring-doc.cn

stubrunner:
  repositoryRoot: classpath:m2repo/repository/
  ids:
    - org.springframework.cloud.contract.verifier.stubs:loanIssuance
    - org.springframework.cloud.contract.verifier.stubs:fraudDetectionServer
    - org.springframework.cloud.contract.verifier.stubs:bootService
  stubs-mode: remote

除了使用属性之外,您还可以使用 . 以下示例通过在 annotation 上设置值来获得相同的结果:@AutoConfigureStubRunnerspring-doc.cn

@AutoConfigureStubRunner(ids = ["org.springframework.cloud.contract.verifier.stubs:loanIssuance",
 "org.springframework.cloud.contract.verifier.stubs:fraudDetectionServer",
 "org.springframework.cloud.contract.verifier.stubs:bootService"] ,
stubsMode = StubRunnerProperties.StubsMode.REMOTE ,
repositoryRoot = "classpath:m2repo/repository/" )

Stub Runner Spring 按以下方式注册环境变量 对于每个已注册的 WireMock 服务器。以下示例显示了 和 的存根运行程序 ID:com.example:thing1com.example:thing2spring-doc.cn

您可以在代码中引用这些值。spring-doc.cn

您还可以使用 Comments 注入正在运行的存根的端口。 注释的值可以是 ,也可以只有 。 以下示例作品显示了 和 的 Stub Runner ID。@StubRunnerPortgroupid:artifactidartifactidcom.example:thing1com.example:thing2spring-doc.cn

@StubRunnerPort("thing1")
int thing1Port;
@StubRunnerPort("com.example:thing2")
