我在intellij idea有一个maven项目。我的pom包含几个依赖项。下面是pom.xml的摘要。我尝试实现junit5，为此我添加了2个依赖项。

我试图实现测试方法，到目前为止，它是有效的。下面是我实施的一个基本测试：

public class AuthenticationManagerTest {

    @Test
    void getAccessTokenByClientCredentialGrant_invalidUrlMissingSegments() throws MalformedURLException {
        authority = "https://somestring";

        Assertions.assertThrows(IllegalArgumentException.class, () ->
                    // ConfidentialClientApplication app =
                    ConfidentialClientApplication.builder(
                            clientId,
                            ClientCredentialFactory.createFromSecret(clientSecret))
                            .authority(authority)
                            .build(),
            "Authority Uri should not have empty path segments"
        );
    }
    ....
}

在尝试使用覆盖率运行它时，我注意到覆盖的代码是0%。有什么东西不见了吗？

我还注意到，当我运行所有测试时，我的pojo类（我根本没有实现任何测试）正在确认20%的覆盖率。
