单元测试提示找不到“Could not find the main class . Progam will exit”

[wangqp1]

使用myeclipse开发工具创建个单元测试，源代码如下

import junit.framework.*;
import UseCase.GeneratePrimes;
package junit.framework;

public class test1 extends TestCase {

public test1(String name) {
super(name);
}

public static void main(String args[])
{
junit.swingui.TestRunner.main(new String[] {"TestGeneratePrimes"});
//testPrimes();
}

public void testPrimes()
{
int[] nullArray = GeneratePrimes.generatePrimes(0);
assertEquals(nullArray.length,0);

int[] minArray = GeneratePrimes.generatePrimes(2);
assertEquals(minArray.length,1);
assertEquals(minArray[0],2);

int[] threeArray = GeneratePrimes.generatePrimes(3);
assertEquals(threeArray.length,2);
assertEquals(threeArray[0],2);
assertEquals(threeArray[1],3);

int[] centArray = GeneratePrimes.generatePrimes(100);
assertEquals(centArray.length,25);
assertEquals(centArray[24],97);
}

}

run as -> Junit test显示如下错误：

jdk版本问题

确实是版本的问题，后来我更改了jdk路径，就ok了。谢谢你们

编译器是myeclipse自带的吧

是的，也引入了junit.jar包了

jdk版本问题

[healer_kx]

jdk版本不对。
jdk没有配置好。
运行按钮选择要启动的程序，你可能选择错了。
