This is the mand I'm using:
$ mocha -b -R spec -s 1000
And it's failing with this message:
1) "before all" hook
0 passing (2s)
1 failing
1) "before all" hook:
Error: timeout of 2000ms exceeded
at null.<anonymous> (/usr/local/lib/node_modules/mocha/lib/runnable.js:159:19)
at Timer.listOnTimeout [as ontimeout] (timers.js:112:15)
Could you please help me figure out why this is caused?
I know that if I change the timeout for the test runner:
$ mocha -b -R spec -s 1000 -t 3000
The tests work. But I want to know the actual cause of this error.
Thank you!

Reset to default 5You get the error you are getting because your top level before hook takes more than the default 2000ms timeout delay to run. In case you did not know: before means "execute this before all tests in this suite" and this is why the error message talks of a "before all" hook.
It works when you do $ mocha -b -R spec -s 1000 -t 3000 because you've increased the timeout to 3000ms. The code in your before hook takes between 2 and 3 seconds to run. You could make this setting permanent by putting it inside test/mocha.opts.
Use BeforeEach instead of Before
The problem is, server.listen is blocking so the done statement in the callback doesn't execute until all of the tests are pleted and server.close is called.
A simple (and IMHO) cleaner solution to prevent from violating the default time limit is to start/stop the server for each test.
Change:
before(function(done) {
xapp(function(sapp) {
app = sapp;
server = app.listen(3000, done);
});
});
after(function(done) {
app.closeMongo(function() {
server.close(done);
});
});
To:
beforeEach(function(done) {
xapp(function(sapp) {
app = sapp;
server = app.listen(3000, done);
});
});
afterEach(function(done) {
app.closeMongo(function() {
server.close(done);
});
});
No test should run longer than 2000ms unless something goes wrong.
Another, potentially better solution, is to use a testing framework specifically designed to test API calls.
