使用集成的 QUnit 测试框架,我需要测试是否访问路由会导致抛出错误。
路由中有一个 Handlebars 助手,它应该在某些条件下抛出错误(断言失败)。如何测试是否抛出此错误?
这是我到目前为止得到的:
test('throws, if the SVG is missing', function() {
throws(visit('/missing'), Error, "has thrown an Error");
});
但它不起作用,因为错误没有被捕获throws(...)
并冒泡到测试框架,将此测试标记为失败。
这是测试输出:

作为visit('/missing')
返回一个承诺,人们会假设 using.then(success, error)
会起作用,但事实并非如此。
