Stub Runner Spring Cloud的最重要特征是它正在存根

这意味着无论您使用的是Zookeeper，Consul，Eureka还是其他任何东西，您都不需要在测试中使用它。我们正在启动依赖项的WireMock实例，并且在您每次使用Feign，直接负载均衡RestTemplate或DiscoveryClient来调用那些存根服务器而不是调用真实服务时，都告诉您的应用程序发现工具。

例如，该测试将通过

def 'should make service discovery work'() {
	expect: 'WireMocks are running'
		"${stubFinder.findStubUrl('loanIssuance').toString()}/name".toURL().text == 'loanIssuance'
		"${stubFinder.findStubUrl('fraudDetectionServer').toString()}/name".toURL().text == 'fraudDetectionServer'
	and: 'Stubs can be reached via load service discovery'
		restTemplate.getForObject('http://loanIssuance/name', String) == 'loanIssuance'
		restTemplate.getForObject('http://someNameThatShouldMapFraudDetectionServer/name', String) == 'fraudDetectionServer'
}

对于以下配置文件

stubrunner:
  idsToServiceIds:
    ivyNotation: someValueInsideYourCode
    fraudDetectionServer: someNameThatShouldMapFraudDetectionServer
