PTTest失败并且没有生成突变覆盖

标签: mutation pitest

我想生成突变测试覆盖率。我在PI Test上做POC 但它没有参加我的测试课程而且失败了。我在pom.xml中配置了PTTest插件。我在pom.xml文件中检查了目标类包名称和目标测试类包名称是否正确。

我收到以下错误 -

这是我的pom.xml文件 -

<plugin>
    <groupId>org.pitest</groupId>
    <artifactId>pitest-maven</artifactId>
    <version>1.1.4</version>
    <configuration>
        <targetClasses>
            <param>com.mutation.dx.pitestdemo</param>
        </targetClasses>
        <targetTests>
            <param>com.mutation.dx.pitestdemo</param>
        </targetTests>
    </configuration>
</plugin>

下面是我想要生成变异的课程

package com.mutation.dx.pitestdemo;

import org.springframework.beans.factory.annotation.Autowired;

public class PIDemoImpl implements PIDemo {

    @Autowired
    private PIDemoDao piDemoDao; 

    @Override
    public PIDto getPIDetails(String name, int firstNumber,int secondNumber) {
        int thirdNumber = firstNumber * secondNumber;
        PIDomain piDomain =  piDemoDao.getPIDomain(name, thirdNumber);
        if(piDomain != null) {
            PIDto piDto = new PIDto();
            piDto.setName(piDomain.getName());
            int result = piDomain.getX() + piDomain.getY();
            if(result >= 0 ) {
                piDto.setResult(result);
            }
            return piDto;
        }
        return null;
    }
}
下面的

是我的测试类 -

package com.mutation.dx.pitestdemo;

import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import static org.mockito.Mockito.when;
import static org.mockito.Mockito.verify;
import org.mockito.runners.MockitoJUnitRunner;

import com.mutation.dx.pitestdemo.PIDemoImpl;

@RunWith(MockitoJUnitRunner.class)
public class PIDemoImplTest {
    @Mock
    private PIDemoDao piDemoDao;

    @InjectMocks
    PIDemoImpl piDemoImpl;

    @Test
    public void getPIDetailsTest(){
        String name = "Persistent";
        int firstNumber = 0;
        int secondNumber = 10;
        int thirdNumber = 0;
        PIDomain piDomain = new PIDomain();
        piDomain.setName(name);
        piDomain.setX(2);
        piDomain.setY(2);
        when(piDemoDao.getPIDomain(name, thirdNumber)).thenReturn(piDomain);
        PIDto piDto = piDemoImpl.getPIDetails(name , firstNumber, secondNumber);
        Assert.assertNotNull(piDto);
        Assert.assertEquals(piDto.getName(),name);
        verify(piDemoDao).getPIDomain(name, thirdNumber);
    }
}

我正在使用mockito来模拟对象。

您的过滤器看起来不正确。 Pitest期望与每个类的完全限定名称匹配的globs。

而不是

com.mutation.dx.pitestdemo

尝试

com.mutation.dx.pitestdemo.*

* wilcard应匹配包中的所有类。

从1.2.0开始targetClassestargetTests通常不需要在从maven运行时指定 - pitest现在将扫描项目并自动确定项目中定义了哪些包。
