  • Mocking Is an Anti-Pattern
    7 projects | | 17 Jun 2024
    Most IO nowadays in my context is to call some REST API. I prefer to use nock ( With that I can create an environment for my test to run in without changing anything about the implementation.

    The article does not seem to bring up this way to do it.

    So, why would you want a REAL server to mock request/reponses? You have a lot of intercepts today that sit on the network layer and you can define things like "If you send request to that endpoint, with that json, please return that Status" (for NodeJS example, Nock -

    That said, folks seem to like "recording" features in these sorts of tools (Ruby's VCR, nock, etc), so maybe there's a future where I add something similar. I've always just found the ergonomics of those features awkward to deal with, especially having to flip back and forth between tests and fixtures files to figure out what's wired to what, but maybe there's a clean solution... perhaps a "live request" mode that just prints mock code snippets of request/response pairs passing through your app.
  • Is there a better way to mock an axios call?

    While not mocking per say I usually use nock for http calls. You can use nock.recorder.rec() to capture the http call to play back during test, That way you are always using "live" code but not making real calls to servers.

  • OSD600 - Telescope - Testing for feed URLs
    4 projects | | 20 Nov 2022
    I looked at the service which is used to get the feed URLs from a blog URL and noticed it takes the html response of the blog URL and gets the links ( tags) by checking the type attribute value against a list of valid feed values. So, I decided to use a similar approach by getting the html response for a provided URL and checking the Content-Type header against a list of valid MIME types for a feed. I ended up updating the logic to test if a URL is a feed URL, returning it if true. If the URL is found to not be a feed URL, it would try to get the feed URLs assuming the URL is a blog URL. I tested and confirmed that the new logic worked for both blog and feed URLs. Then, I added some tests for the new function I added to test for a feed URL. Testing this ended up being simpler than I expected as all I had to do was mock the response of a test url (using nock), and then check if the function returned the correct boolean value for a url. I created a PR and noticed that some of the tests in another file were now failing. While I was investigating this, I got a review on my PR, requesting me to add another test to the file which had the failing tests. That file tested the API service as a whole. I found out that nock only mocks a URL's response for one request by default. And since I was now checking for a feed URL as well, the function which returned the feed URLs from a blog URL was throwing an error since the nock for that was used up. To fix this, I had to specify in the nock statement to mock the URL response for two requests:
