PTTest zawodzi i nie generuje pokrycia mutacji

Question

Chcę wygenerować pokrycia testu mutacji. Robię POC na próbie PI , ale to nie bierze moich klas testowych i się nie udaje. Mam skonfigurowaną wtyczkę PTTest w pom.xml. Sprawdziłem nazwę pakietu docelowej klasy i docelową nazwę pakietu klasy testowej w pliku pom.xml.

otrzymuję poniżej błędu -

To jest mój plik pom.xml -

<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> 

poniżej jest moja klasa, na których chcę generować mutację

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; 
    } 
} 

poniżej znajduje się moja klasa testowa -

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); 
    } 
} 

Używam mockito do kpiny z obiektów.

Answer 1

Twoje filtry wyglądają nieprawidłowo. Pitest oczekuje globów, które są dopasowane do w pełni kwalifikowanej nazwy każdej klasy.

Zamiast

com.mutation.dx.pitestdemo

Spróbuj

com.mutation.dx.pitestdemo.*

* wilcard należy następnie dopasować wszystkie zajęcia w opakowaniu.

Od wersji 1.2.0 targetClasses i targetTests zwykle nie trzeba określać podczas uruchamiania z maven - pitest teraz skanuje projekt i automatycznie określa, które pakiety są zdefiniowane w projekcie.
