An example of an AI chatbot conversation about handling errors in Mocha tests.
How do I handle errors in Mocha tests?
In Mocha, you can handle errors by using the 'done' callback or returning a promise. Would you like examples?
Yes, please provide an example using the 'done' callback.
Sure! You can write a test like this:
it('should return an error', function(done) {
someAsyncFunction(function(err, result) {
if (err) return done(err);
// assertions here
done();
});
});
What about using promises instead?
When using promises, you can return the promise directly:
it('should return an error', function() {
return someAsyncFunction().catch(err => {
// assertions here
});
});
