使用dropwizard(4)-加入测试-jacoco代码覆盖率

前言

dropwizard提供了一个简单的测试框架。这里简单集成并加入jacoco测试。

Demo source

https://github.com/Ryan-Miao/l4dropwizard

本文是基于dropwizard入门之上的演进。

确保依赖都是最新的,或者自行解决版本冲突,比如jackson不同版本之间的类有所不同。

加入dropwizard-testing

在dependencies中增加依赖

编写测试

首先,更新依赖,

1
mvn clean install

IDEA中刷新maven按钮。

然后,新建Resource测试类:

@After
public void tearDown(){

reset(service);
}
@Test
public void testGetPerson() {
GithubUser user = new GithubUser();
String name = "Ryan";
user.setName(name);
when(service.getUserProfile(anyString())).thenReturn(user);
GithubUser githubUser = resources.target("/github/users/ryan-miao").request().get(GithubUser.class);
assertEquals(name, githubUser.getName());

}
}

验收,查看覆盖率

1
mvn clean install

查看jacoco覆盖率
