我有一个测试套件，我围绕包含~350个测试的JavaScript应用程序代码构建。我的测试是通过从节点命令行运行grunt test来运行的。每次测试运行时，我会在停止之前运行不同数量的测试。它很少完成我的所有测试。以前有没有人发生过这种事情？有什么可能导致它的想法？
当我运行测试时，我通常会在270 - 350测试完成后得到一个看似随机的数字。测试结束后，我没有任何错误或任何错误。结尾说的是：
Finished in 1.332 secs / 0.823 secs
Summary:
√ 311 test completed
以下是一个很少运行的测试示例：

it('should create the global SeniorHomes object', function() {
expect(sh).to.be.an('object');
});
describe('sh.cookies.create', function() {
sh.cookies.create('name', 'value', 10);
it('should create a cookie', function() {
var cookies = document.cookie.split('; '),
cookie;
$.each(cookies, function(i, item) {
if (item.split('=')[0] === 'name') {
cookie = {
name: item.split('=')[0],
value: item.split('=')[1]

expect(cookie.name).to.equal('name');

答案 0 :(得分：0)
当我将测试作为单次运行运行时，它会因警告而中止。关于进行整页重新加载的一些测试有一些警告。所以，我删除了两个函数的测试：
请求桌面版：添加Cookie并重新加载页面以仅获取桌面样式。
请求移动版本：删除cookie并重新加载以获取移动样式
删除这些后，我会收到一系列完整的测试，并显示“完成，没有错误。”
