关于testhome junit参数化的问题解决

问题的描述来自： https://testerhome.com/topics/9295

问题的描述是无法获取参数化， 我也心血来潮，自己花了几分钟改正问题

@RunWith(Parameterized.class) public class ResultParamTest { private int actCode; private String actMessage; private int expCode; private String expMessage; public ResultParamTest(int expCode, int actCode, String expMessage, String actMessage) { this.expCode = expCode; this.actCode = actCode; this.expMessage = expMessage; this.actMessage = actMessage; } @Parameterized.Parameters public static Collection prepareData() throws IOException { ResultParam resultParam = new ResultParam("test_case.xlsx", 0); ArrayList<Integer> a = resultParam.expCode(); ArrayList<Integer> b = resultParam.actCode(); ArrayList<String> c = resultParam.expMessage(); ArrayList<String> d = resultParam.actMessage(); Object[][] objects = {{a.get(0), b.get(0), c.get(0), d.get(0)}, {a.get(1), b.get(1), c.get(1), d.get(1)},........{}....{}}; return Arrays.asList(objects); } @Test public void testResultParam() throws IOException { Assert.assertEquals(expCode, actCode); Assert.assertEquals(expMessage, actMessage); } }

改正后的代码：

package com.mj; import static org.junit.Assert.*; import java.util.ArrayList; import java.util.Arrays; import java.util.Collection; import junit.framework.Assert; import org.junit.After; import org.junit.Before; import org.junit.Test; import org.junit.runner.RunWith; import org.junit.runners.Parameterized; @RunWith(Parameterized.class) public class CalculatorTest { private int actCode; private String actMessage; private int expCode; private String expMessage; public CalculatorTest(int expCode, int actCode, String expMessage, String actMessage) { this.expCode = expCode; this.actCode = actCode; this.expMessage = expMessage; this.actMessage = actMessage; } @Parameterized.Parameters public static Collection prepareData() { ArrayList<Integer> a = new ArrayList<Integer>(); ArrayList<Integer> b = new ArrayList<Integer>(); ArrayList<String> c = new ArrayList<String>(); ArrayList<String> d = new ArrayList<String>(); // 五个正常用例 for (int i = 0; i < 5; i++) { a.add(i); b.add(i); c.add("正确" + i); d.add("正确" + i); } // 五个非正常用例 for (int i = 0; i < 5; i++) { a.add(i); b.add(i + 1); c.add("正确" + i); d.add("错误" + (i + 1)); } int size = a.size() - 1; Object[][] objList = new Object[size][4]; for (int i = 0; i < objList.length; i++) { objList[i][0] = a.get(i); objList[i][1] = b.get(i); objList[i][2] = c.get(i); objList[i][3] = d.get(i); } return Arrays.asList(objList); } @Test public void test() { System.err.println("expCode is " + expCode + " actCode is " + actCode + " expMessage is " + expMessage + " actMessage is " + actMessage); assertEquals(expCode, actCode); assertEquals(expMessage, actMessage); } }

运行打印数据： expCode is 0 actCode is 0 expMessage is 正确0 actMessage is 正确0 expCode is 1 actCode is 1 expMessage is 正确1 actMessage is 正确1 expCode is 2 actCode is 2 expMessage is 正确2 actMessage is 正确2 expCode is 3 actCode is 3 expMessage is 正确3 actMessage is 正确3 expCode is 4 actCode is 4 expMessage is 正确4 actMessage is 正确4 expCode is 0 actCode is 1 expMessage is 正确0 actMessage is 错误1 expCode is 1 actCode is 2 expMessage is 正确1 actMessage is 错误2 expCode is 2 actCode is 3 expMessage is 正确2 actMessage is 错误3 expCode is 3 actCode is 4 expMessage is 正确3 actMessage is 错误4

因为我对群友的业务不熟悉，加上我没有 ResultParam resultParam = new ResultParam("test_case.xlsx", 0); 这个类的代码，我就自己制作了点数据。

其实这里我只是简单的测试，应该用等价类，边界值加上点数据的，只是在上班时间，顺带赶紧记录下。
