Java 如何为单元测试Spring云功能配置maven项目
使用功能和单元测试设置SpringCloud项目的正确方法是什么 我想用SpringCloud功能创建一个独立的web应用程序，并有可能通过单元测试来覆盖它。我已根据以下步骤进行设置：Java 如何为单元测试Spring云功能配置maven项目,java,spring,maven,spring-cloud,spring-cloud-function,Java,Spring,Maven,Spring Cloud,Spring Cloud Function,使用功能和单元测试设置SpringCloud项目的正确方法是什么 我想用SpringCloud功能创建一个独立的web应用程序，并有可能通过单元测试来覆盖它。我已根据以下步骤进行设置： 我用springbootstarter父级创建了maven项目 在dependencyManagement中添加了spring云依赖项 添加了springcloudstarter功能webstarter 添加了测试依赖项： 将第5版的junit bom添加到dependencyManagement 添加了spr

有关更多信息/示例Oleg，您的问题在标题中有点不清楚，因为您似乎明确希望将函数部署为web端点并进行测试。这与“如何测试弹簧功能”不同。
不管怎样，我们可能需要更新我们的文档，以使其更清晰，但它就在这里
假设这是您的应用程序：
@SpringBootApplication
public class SampleFunctionApplication {
public static void main(String[] args) {
SpringApplication.run(SampleFunctionApplication.class, args);
}
@Bean
public Function<String, String> uppercase() {
return v -> v.toUpperCase();
}
}

有关更多信息/示例对不起，我们的示例不清楚。我创建了一些函数，将它们标记为bean，并希望通过单元测试来覆盖它们。此外，我还想检查它如何处理HTTP请求。我在以前版本的文档中看到，我可能会使用WebTestClient
进行测试，但在我的示例中它不起作用，并且无法注入WebTestClient
bean。感谢您的回复。这有点帮助。我可以做单元测试。不幸的是，testrestemplate
没有提供像MockMvc
或WebTestClient
这样的断言方法。在您的示例中，Spring测试是否在本地部署服务器？很抱歉，还不清楚。我创建了一些函数，将它们标记为bean，并希望通过单元测试来覆盖它们。此外，我还想检查它如何处理HTTP请求。我在以前版本的文档中看到，我可能会使用WebTestClient
