Squaretest 自动生成 Mockito 单元测试

1. 安装 Squaretest 插件

引入 Mockito 依赖

<dependency>
    <groupId>org.mockito</groupId>
    <artifactId>mockito-all</artifactId>
    <version>1.9.0</version>
    <scope>test</scope>
</dependency>

2. 自动生成测试类

右击类 -> Generate... -> Generate Test

选择对应的JUnit版本

3. 查看单元测试类

@Service
public class GreetServiceImpl implements GreetService {
    @Resource
    private OrderDao orderDao;

    @Override
    public String greet() {
        Order query = orderDao.query();
        int i = 2 + 3;
        return "greet";
    }
}

生成的单元测试类

import org.mockito.InjectMocks;
import org.mockito.Mock;

@ExtendWith(MockitoExtension.class)
class GreetServiceImplTest {

    @Mock
    private OrderDao mockOrderDao;

    @InjectMocks
    private GreetServiceImpl greetServiceImplUnderTest;

    @Test
    void testGreet() {
        // Setup
        // Configure OrderDao.query(...).
        final Order order = new Order();
        order.setId(0);
        order.setCode("code");
        order.setUserName("userName");
        when(mockOrderDao.query()).thenReturn(order);

        // Run the test
        final String result = greetServiceImplUnderTest.greet();

        // Verify the results
        assertThat(result).isEqualTo("greet");
    }
}

执行单元测试

4. 查看代码覆盖率

添加依赖

<dependency>
    <groupId>org.jacoco</groupId>
    <artifactId>jacoco-maven-plugin</artifactId>
    <version>0.8.8</version>
</dependency>

配置maven plugin 插件

<build>
    <plugins>
        <!--使用 jacoco 生成覆盖率报告-->
        <plugin>
            <groupId>org.jacoco</groupId>
            <artifactId>jacoco-maven-plugin</artifactId>
            <version>0.8.8</version>
            <configuration>
                <includes>
                    <include>com/**/*</include>
                </includes>
            </configuration>
            <executions>
                <execution>
                    <id>pre-test</id>
                    <goals>
                        <goal>prepare-agent</goal>
                    </goals>
                </execution>
                <execution>
                    <id>post-test</id>
                    <phase>test</phase>
                    <goals>
                        <goal>report</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>
