# Discourse Developer Testing Guide
|
|
|
|
Some notes about testing Discourse:
|
|
|
|
## FakeWeb
|
|
|
|
We use the [FakeWeb](https://github.com/chrisk/fakeweb) gem to fake external web
|
|
requests.
|
|
For example, check out the specs on `specs/components/oneboxer`.
|
|
|
|
This has several advantages to making real requests:
|
|
|
|
* We freeze the expected response from the remote server.
|
|
* We don't need a network connection to run the specs.
|
|
* It's faster.
|
|
|
|
So, if you need to define a spec that makes a web request, you'll have to record
|
|
the real response to a fixture file, and tell FakeWeb to respond with it for the
|
|
URI of your request.
|
|
|
|
Check out `spec/components/oneboxer/amazon_onebox_spec.rb` for an example on
|
|
this.
|
|
|
|
### Recording responses
|
|
|
|
To record the actual response from the remote server, you can use curl and save the response to a file. We use the `-i` option to include headers in the output
|
|
|
|
curl -i http://en.m.wikipedia.org/wiki/Ruby > wikipedia.response
|
|
|
|
If you need to specify the User-Agent to send to the server, you can use `-A`:
|
|
|
|
curl -i -A 'Mozilla/5.0 (iPhone; CPU iPhone OS 5_0_1 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9A405 Safari/7534.48.3' http://en.m.wikipedia.org/wiki/Ruby > wikipedia.response
|
|
|
|
If the remote server is responding with a redirect, you'll need to fake both the
|
|
original request and the one for the destination. Check out the
|
|
`wikipedia.response` and `wikipedia_redirected.response` files in
|
|
`spec/fixtures/oneboxer` for an example. You can also consider working directly
|
|
with the final URL for simplicity.
|
|
|
|
|
|
## MailCatcher
|
|
|
|
Discourse depends heavily on (sending) email for notifications. We use [MailCatcher](http://mailcatcher.me/)
|
|
to test emails. It's super convenient!
|
|
|
|
> MailCatcher runs a super simple SMTP server which catches any message sent to it to display in a web interface. Run mailcatcher, set your favourite app to deliver to smtp://127.0.0.1:1025 instead of your default SMTP server, then check out http://127.0.0.1:1080 to see the mail that's arrived so far.
