如何告诉QUnit在 asyncTest
期间将错误视为测试失败并继续进行下一次测试?
How can I tell QUnit to consider errors during asyncTest
as test failures and continue to next test?
这是一个示例,在 ReferenceError
之后QUnit停止运行:

推荐答案
如果在QUnit未正式运行时出现异步测试中的错误,则会出现静默。
Errors in asynchronous tests die silently if they arise while QUnit isn't officially running.
最简单的解决方案是将每个 asyncTest
内容包装在try / catch块中,该块在 >重新启动QUnit。我们实际上不需要用一百万次尝试/捕获来污染代码 - 我们可以自动装饰你现有的方法。
The simplest solution is to wrap every asyncTest
contents in a try/catch block that propagates any errors after restarting QUnit. We don't actually have to pollute the code with a million try/catches--we can decorate your existing methods automagically.
例如:
// surrounds any function with a try/catch block to propagate errors to QUnit when
// called during an asyncTest
function asyncTrier(method) {
return function () {
try{
// if the method runs normally, great!
method();
} catch (e) {
// if not, restart QUnit and pass the error on
QUnit.start();
throw new (e);
}
};
}
QUnit.asyncTest("sample", 1, function () {
setTimeout(asyncTrier(function(){
var foo = window.nonexistentobj.toString() + ""; // throws error
QUnit.ok("foo defined", !!foo)
QUnit.start();
}), 1000);
});
使用示例包装方法分叉您的小提琴,以便在每个异步块周围自动应用此类try / catch :
