  • I made wirepig, a simple way to mock HTTP and TCP dependencies in tests.

    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.

    When it comes time to test these applications, things can get awkward. Do I stand up a real redis instance to test against? Do I stub out functions to "fake" the network calls? Do I use a tool like nock that monkey patches node's standard lib?
  • Is there a better way to mock an axios call?
    2 projects | /r/reactjs | 28 Jan 2023
    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 | dev.to | 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:
  • What features would you consider missing/nice to haves for backend web development in Rust?

  • Axios shipped a buggy version and it broke many productions apps. Let this be a lesson to pin your dependencies!
    5 projects | /r/node | 7 Oct 2022
    For example in my backend project I use Nock to do so. This library captures the request before sending them and you can validate the expected url to have all properties required.

    There are libraries like https://github.com/nock/nock to prevent mocking the whole axios.
  • Is it acceptable to use mock servers, like Postman, for testing in Android?

    If youโ€™re willing to venture into nodejs territory, then nock is a fantastic and simple to set up http mock server. https://github.com/nock/nock
  • Mocking API calls in React Tests with Nock
    5 projects | dev.to | 16 Aug 2022
    We'll use a third-party package called nock that helps us to mock HTTP requests. With nock, we can specify the desired behavior of our mock HTTP requests, including the URL, headers, and body. This allows us to test our code against a known data set, making debugging and testing much more straightforward.
