使用天蓝色的junit测试在SpringCloud函数中出现错误

我只是想用天蓝色的功能测试来设置我的springcloud以适应环境。当我仅作为SpringBoot / Cloud应用程序运行时，它运行良好。当我添加Azure适配器时，它使我添加了带有一堆注释的类，如下所示。

在尝试升级到Azure本身之前，我试图使其在junit中运行。 

public class AzureReverseAdapter extends AzureSpringBootRequestHandler<String, String> {

    public AzureReverseAdapter() {
        super();
        // TODO Auto-generated constructor stub
    }

    public AzureReverseAdapter(Class<?> configurationClass) {
        super(configurationClass);
        // TODO Auto-generated constructor stub
    }

    @FunctionName("reverseString")
    public String execute(
            @HttpTrigger(name = "request", methods = {HttpMethod.GET, HttpMethod.POST}, authLevel = AuthorizationLevel.ANONYMOUS) HttpRequestMessage<Optional<String>> request,
            ExecutionContext context) {

        context.getLogger().info("Input: " + request.getBody().get());
        return handleRequest(request.getBody().get(), context);
    }

}

但是要进行以下测试：

    @Test
    public void start() throws Exception {
//        AzureSpringBootRequestHandler<String, String> handler = new AzureSpringBootRequestHandler<String, String>(CloudFunctionApplication.class);
        AzureReverseAdapter handler = new AzureReverseAdapter(CloudFunctionApplication.class);
        String result = handler.handleRequest("Hello World", null);
        handler.close();
        Assert.assertEquals(result, "dlroW olleH");
    }

引发此异常：

我想我重现了我正在努力的示例。所以我不确定我缺少什么。当我查找该侦听器类的Javadoc时，该错误似乎抱怨缺少application.properties。我在类路径的根目录中添加了application.properties。同样的错误。我不确定是否需要定义哪些属性。

问题来自pom.xml。当应用尝试调用抽象方法时，将引发java.lang.AbstractMethodError。您的代码可以使用较早的版本，但是在pom.xml中设置的较新版本使该方法变得抽象。解决方法是在pom.xml的设置中尝试使用早期版本。

这样设置（在modelVersion下）：

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.0.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository --></relativePath>
</parent>

尝试使用比您所知道的更早的版本。
