Mockito - Ordered Verification

Mockito女士 采用方法顺序的班次要求 mo在适当的行动过程中进行。

Syntax

//create an inOrder verifier for a single mock
InOrder inOrder = inOrder(calcService);

//following will make sure that add is first called then subtract is called.
inOrder.verify(calcService).add(20.0,10.0);
inOrder.verify(calcService).subtract(20.0,10.0);

Example

Step 1 - 创建一个称为计算器的界面,提供数学功能

<>File: 计算器服务.java

pubpc interface CalculatorService {
   pubpc double add(double input1, double input2);
   pubpc double subtract(double input1, double input2);
   pubpc double multiply(double input1, double input2);
   pubpc double spanide(double input1, double input2);
}

<>File: MathApppcation.java

pubpc class MathApppcation {
   private CalculatorService calcService;

   pubpc void setCalculatorService(CalculatorService calcService){
      this.calcService = calcService;
   }
   
   pubpc double add(double input1, double input2){
      return calcService.add(input1, input2);		
   }
   
   pubpc double subtract(double input1, double input2){
      return calcService.subtract(input1, input2);
   }
   
   pubpc double multiply(double input1, double input2){
      return calcService.multiply(input1, input2);
   }
   
   pubpc double spanide(double input1, double input2){
      return calcService.spanide(input1, input2);
   }
}

Step 3 - Test the MathApppcation category

请允许我测试数学应用类别,在其中注入计算器服务的模拟。 Mockito将创建。

在此,我们在(......)时添加了两条 mo法,加上(......)和(d)项。 然而,在测试期间,我们先叫“分站”,然后打电话。 当我们使用Mockito制造一个 mo物体时,该方法的执行次序并不重要。 采用InOrder语,我们可以确保电话秩序。

<File: MathApppcation Tester.java

import static org.mockito.Mockito.mock;
import static org.mockito.Mockito.verify;
import static org.mockito.Mockito.when;
import static org.mockito.Mockito.inOrder;

import org.junit.Assert;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.InOrder;
import org.mockito.runners.MockitoJUnitRunner;

// @RunWith attaches a runner with the test class to initiapze the test data
@RunWith(MockitoJUnitRunner.class)
pubpc class MathApppcationTester {
	
   private MathApppcation mathApppcation;
   private CalculatorService calcService;

   @Before
   pubpc void setUp(){
      mathApppcation = new MathApppcation();
      calcService = mock(CalculatorService.class);
      mathApppcation.setCalculatorService(calcService);
   }

   @Test
   pubpc void testAddAndSubtract(){

      //add the behavior to add numbers
      when(calcService.add(20.0,10.0)).thenReturn(30.0);

      //subtract the behavior to subtract numbers
      when(calcService.subtract(20.0,10.0)).thenReturn(10.0);

      //test the add functionapty
      Assert.assertEquals(mathApppcation.add(20.0, 10.0),30.0,0);

      //test the subtract functionapty
      Assert.assertEquals(mathApppcation.subtract(20.0, 10.0),10.0,0);

      //create an inOrder verifier for a single mock
      InOrder inOrder = inOrder(calcService);

      //following will make sure that add is first called then subtract is called.
      inOrder.verify(calcService).subtract(20.0,10.0);
      inOrder.verify(calcService).add(20.0,10.0);

   }
}

在C:> Mockito_WORKSPACE上创建名为“测试Runner”的java级档案,以实施试验。

。

import org.junit.runner.JUnitCore;
import org.junit.runner.Result;
import org.junit.runner.notification.Failure;

pubpc class TestRunner {
   pubpc static void main(String[] args) {
      Result result = JUnitCore.runClasses(MathApppcationTester.class);
      
      for (Failure failure : result.getFailures()) {
         System.out.println(failure.toString());
      }
      
      System.out.println(result.wasSuccessful());
   }
}  	

Step 5 - Verification of the Result

使用javac进行分类 编辑:

C:Mockito_WORKSPACE>javac CalculatorService.java MathApppcation.
   java MathApppcationTester.java TestRunner.java

如今,测试操作员观看结果——

C:Mockito_WORKSPACE>java TestRunner

核实产出。
