測試類生成截圖

測試類名，勾選測試方法

　　會在測試類的包中自動生成測試類
package com.example.news;
import org.junit.Before;
import org.junit.Test;
import static org.junit.Assert.*;
/**
* Created by 小新 on 2016/7/1.
*/
public class CalculatorTest {
@Before
public void setUp() throws Exception {
}
@Test
public void testSum() throws Exception {
}
@Test
public void testSubstract() throws Exception {
}
@Test
public void testDivide() throws Exception {
}
@Test
public void testMultiply() throws Exception {
}
@Test
public void testAddMore() throws Exception {
}
}
　　然后進行測試
package com.example.news;
import org.junit.Before;
import org.junit.Test;
import static org.junit.Assert.*;
/**
* Created by 小新 on 2016/7/1.
*/
public class CalculatorTest1 {
private Calculator calculator;
@Before
public void setUp() throws Exception {
calculator = new Calculator();
}
@Test
public void testSum() throws Exception {
//測試sum函數(shù)，因為sum函數(shù)返回的是兩個數(shù)的合為3
//這里期望返回的值是9
//所以會報錯
assertEquals(9d，calculator.sum(1d，2d)，0);
}
@Test
public void testSubstract() throws Exception {
}
@Test
public void testDivide() throws Exception {
}
@Test
public void testMultiply() throws Exception {
}
@Test
public void testAddMore() throws Exception {
}
}
　　運行這個類，結(jié)果為報錯，這個時候我們需要修改函數(shù)了
　　到這里我們JUnix的簡單測試結(jié)束了
