@end您可以使用它进行异步测试。
[MochaAsyncTest runBlock:^(MochaAsyncDone done, MochaAsyncDoneWithError error) {
/*
async function
*/
done();
// or
error(error);
}];通过测试时，您必须调用 done()
如果测试失败，您必须调用 fail(NSError *error)
describe(@"MochaAsyncTest", ^{
it(@"pass test", ^{
[MochaAsyncTest runBlock:^(MochaAsyncDone done, MochaAsyncDoneWithError error) {
// async function
double delayInSeconds = 2.0;
dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(delayInSeconds * NSEC_PER_SEC));
dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);
dispatch_after(popTime, queue, ^(void) {
done();// => done async test
});
}];
});
it(@"fail test", ^{
[MochaAsyncTest runBlock:^(MochaAsyncDone done, MochaAsyncDoneWithError error) {
// async function
double delayInSeconds = 2.0;
dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(delayInSeconds * NSEC_PER_SEC));
dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);
dispatch_after(popTime, queue, ^(void) {
// fail
fail([[NSError alloc] initWithDomain:@"xxx" code:0 userInfo:@{}]);
});
}];
});
});当使用 Kiwi 和 error(NSError *error) 时，虽然测试失败，但会抛出异常...
