JUNIT @ParameterizedTest，參數解析異常

[英]JUNIT @ParameterizedTest , Parameter resolution Exception

問題描述

Eclipse 版本 - 4.19.0 Maven 版本 - 3.8.1

在 JUnit 中，我正在嘗試使用 @CsvSource 或 @MethodSource 實現 @ParameterizedTest。 兩者都因 org.junit.jupiter.api.extension.ParameterResolutionException 而失敗：

有人可以幫助我做錯什么。

以下是我實現堆棧功能的 class。

package com.skill.apps;

import java.util.Stack;
import org.testng.Assert;

public class StackOperations 
{
    static Stack<Integer> stack;
    
    public StackOperations()
    {
        stack = new Stack<Integer>();
        
    }
    
    public boolean push(Integer element)
    {
        int iBeforePush = stack.size();
        stack.push(element);
        if(iBeforePush < stack.size())
            return true;
        else
            return false;
        
    }
    public boolean pop(Integer element)
    {
        
        

        //int iLastElement = stack.lastElement();
        System.out.println(stack.lastElement());
        stack.pop();
        if(element !=  stack.lastElement())
            return true;
        else
            return false;
        
    }
    public int peek(Integer element)
    {
        Integer iElement = stack.peek();
        if(iElement == element)
            return iElement;
        else
            return 0;
                    
    }
    public Integer[] display()
    {
        Integer[] T = null;
        Integer[] iList =  stack.toArray(T);
        
        return iList;
    }
    
}

以下是我的測試 class

package com.skill.test;

import org.junit.jupiter.params.ParameterizedTest;
import org.junit.jupiter.params.provider.CsvSource;
import org.junit.runner.RunWith;
import org.junit.runners.Parameterized;
import org.testng.Assert;

import com.skill.apps.StackOperations;



public class StackOperationsTest {

    private Integer input;
    private Boolean expected;

    
    static StackOperations obj = new StackOperations();
    
    
    public StackOperationsTest(int input, boolean expected) {
        this.input = input;
        this.expected = expected;
        
    }

    /*//@Parameters
    private static Stream<Arguments> testDataForPush()
    {
        return Stream.of(
                Arguments.of(100,Boolean.TRUE),
                Arguments.of(200,Boolean.TRUE),
                Arguments.of(300,Boolean.TRUE)
                
        );
        
        
    }*/ 
    
    
    @ParameterizedTest(name = "#{index} - Test with String : {0}")
    @CsvSource({
        "100, Boolean.TRUE",
        "200, Boolean.TRUE"
    })
    //@MethodSource("testDataForPush")
    public void testPush() 
    {

        Boolean bResult = obj.push(input);
        Assert.assertEquals(bResult, expected);
    
    }
}

您需要在測試用例中接受定義的參數作為參數，然后使用它們。

import org.junit.jupiter.params.ParameterizedTest;
import org.junit.jupiter.params.provider.CsvSource;

import static org.junit.jupiter.api.Assertions.assertEquals;

public class StackOperationsTest {

    static StackOperations obj = new StackOperations();

    @ParameterizedTest(name = "#{index} - Test with String : {0}")
    @CsvSource({
        "100, TRUE",
        "200, TRUE"
    })
    public void testPush(int number, boolean result) {
        // Use number and result to verify if your logic is working or not.
