我想生成突变测试覆盖率。我正在对 PI 测试进行 POC 但这并不是参加我的考试类(class)而失败。我已经在 pom.xml 中配置了 PTTest 插件。我检查了pom.xml文件中的目标类包名称和目标测试类包名称是否正确。
我遇到以下错误 -

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>
下面是我想要生成突变的类
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。
最佳答案
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相匹配的 glob。
而不是
com.mutation.dx.pitestdemo
尝试
com.mutation.dx.pitestdemo.*
* 通配符应该匹配包中的所有类。
从 1.2.0 开始，从 maven 运行时通常不需要指定 targetClasses 和 targetTests - Pitest 现在将扫描项目并自动确定定义了哪些包在项目中。
关于mutation - PTTest 失败并且未生成突变覆盖率，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/32345833/
