本文主要是介绍使用dropwizard(4)-加入测试-jacoco代码覆盖率,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
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。

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
<dependency><groupId>io.dropwizard</groupId><artifactId>dropwizard-testing</artifactId><version>${dropwizard.version}</version><scope>test</scope>
</dependency>
新增Mockito
<dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.12</version>
</dependency>
<dependency><groupId>org.mockito</groupId><artifactId>mockito-core</artifactId><version>2.12.0</version><scope>test</scope>
</dependency>
新增jacoco
在properties下新增
<jacoco.skip.instrument>true</jacoco.skip.instrument>
<jacoco.percentage.instruction>0.01</jacoco.percentage.instruction>
<jacoco.percentage.branch>0</jacoco.percentage.branch>
在plugin新增
<plugin><groupId>org.jacoco</groupId><artifactId>jacoco-maven-plugin</artifactId><configuration><excludes><exclude>**/ioc/**/*</exclude><exclude>**/exceptions/**/*</exclude><exclude>**/connector/*</exclude><exclude>**/valueobject/**/*</exclude><exclude>**/exception/**/*</exclude><exclude>**/entity/**/*</exclude><exclude>**/constant/*</exclude><exclude>**/*Test.*</exclude><exclude>**/Dagger*</exclude><exclude>**/*Factory.*</exclude><exclude>**/*Module.*</exclude></excludes></configuration><executions><execution><id>jacoco-initialize</id><goals><goal>prepare-agent</goal></goals></execution><execution><id>jacoco-check</id><phase>test</phase><goals><goal>check</goal></goals><configuration><rules><rule implementation="org.jacoco.maven.RuleConfiguration"><element>BUNDLE</element><limits><limit implementation="org.jacoco.report.check.Limit"><counter>INSTRUCTION</counter><value>COVEREDRATIO</value><minimum>${jacoco.percentage.instruction}</minimum></limit><limit implementation="org.jacoco.report.check.Limit"><counter>BRANCH</counter><value>COVEREDRATIO</value><minimum>${jacoco.percentage.branch}</minimum></limit></limits></rule></rules></configuration></execution><execution><id>jacoco-report</id><phase>test</phase><goals><goal>report</goal></goals></execution><execution><id>jacoco-instrument</id><phase>test</phase><goals><goal>instrument</goal></goals><configuration><skip>${jacoco.skip.instrument}</skip></configuration></execution></executions>
</plugin>
编写测试
首先,更新依赖,
mvn clean install
IDEA中刷新maven按钮。
然后,新建Resource测试类:
package com.test.domain.resource;import com.test.domain.entiry.GithubUser;
import com.test.domain.service.IGithubService;
import io.dropwizard.testing.junit.ResourceTestRule;
import org.junit.After;
import org.junit.Before;
import org.junit.ClassRule;
import org.junit.Test;import static org.junit.Assert.assertEquals;
import static org.mockito.ArgumentMatchers.anyString;
import static org.mockito.Mockito.mock;
import static org.mockito.Mockito.reset;
import static org.mockito.Mockito.verify;
import static org.mockito.Mockito.when;/*** Created by Ryan Miao on 11/20/17.*/
public class GithubResourceTest {private static final IGithubService service = mock(IGithubService.class);@ClassRulepublic static final ResourceTestRule resources = ResourceTestRule.builder().addResource(new GithubResource(service)).build();@Beforepublic void setup() {}@Afterpublic void tearDown(){// we have to reset the mock after each test because of the// @ClassRule, or use a @Rule as mentioned below.reset(service);}@Testpublic 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());verify(service).getUserProfile("ryan-miao");}}
验收,查看覆盖率
mvn clean install
查看jacoco覆盖率
report在target/site/jacoco/index.html
