错误：java.lang.Exception: No tests found matching Method testPrePage1(egou_manager_web.TestEBrand) from org.junit.internal.requests.ClassRequest@4f3cc73c

今天测试分页时出现以下错误：

java.lang.Exception: No tests found matching Method testPrePage1(egou_manager_web.TestEBrand) from org.junit.internal.requests.ClassRequest@4f3cc73c

    at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:192)

测试代码如下：

@Test
    public void testPrePage1() {

        ClassPathXmlApplicationContext ac = new ClassPathXmlApplicationContext("spring/applicationContext_*.xml");
        BrandService brandService = (BrandService) ac.getBean("brandService");
        EBrandExample example = new EBrandExample();
        // 执行查询，并分页
        // 分页处理
        PageHelper.startPage(2, 3);
        List<EBrand> list = brandService.selectByExample(example);
        // 取商品列表
        for (EBrand tbItem : list) {
            System.out.println(tbItem);
        }
        // 取分页信息
        PageInfo<EBrand> pageInfo = new PageInfo<EBrand>(list);
        long total = pageInfo.getTotal();
        System.out.println("共有商品：" + total);

    }

不知哪里出了问题？望高手告知~~
