Exploring ways to run tests on a server REST API using testem

When using Testem, I have a config option called serve_files that handles serving the client-side code for me. However, I also need to run my server because it includes a REST API that the client side relies on.

Is there a way to configure Testem to launch my server before running the tests? Or is this not allowed by Testem's guidelines?

The issue arises because Testem runs on a different port than my REST API, which causes problems with API references in the client side. Therefore, I'm looking to instruct Testem to ignore serve_files and instead start my actual server to test the files from there.

PS: Another possibility could be to stub the API using sinonjs or similar tools. However, doing so would mean I'm not truly testing my API with the Ember generated templates that interact with it.

Answer №1

If you need to forward http requests to an external endpoint, consider utilizing the API Proxy setting:

To achieve this, simply include a proxies section in the testem.json configuration file.


{
  "proxies": {
    "/api": {
      "port": 4200,
      "host": "localhost"
    },
    "/xmlapi": {
      "port": 8000,
      "host": "localhost"
    }
  }
}

This feature is set up as a transparent proxy, meaning that a request like 

http://localhost:7357/api/posts.json
will be forwarded to 
http://localhost:4200/api/posts.json
while retaining the /api prefix.
