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);    @ClassRule    public static final ResourceTestRule resources = ResourceTestRule.builder()            .addResource(new GithubResource(service))            .build();    @Before    public void setup() {    }    @After    public void tearDown(){        // we have to reset the mock after each test because of the        // @ClassRule, or use a @Rule as mentioned below.        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());        verify(service).getUserProfile("ryan-miao");    }}

验收，查看覆盖率

mvn clean install

查看jacoco覆盖率
