Improve documentation on Stubs

[michaelisvy]

Hi,
first of all I'd like to thank you for the great work on Sinon. I've been using it for a few weeks and it helps us a lot having better tests.
I would be happy to work on this issue if you're interested.

Is your feature request related to a problem? Please describe.
I was discussing with my colleagues about the fact that the sinon documentation is often not enough and that we need to search on the web / go on stackoverflow to get more examples before we can understand things.

Describe the solution you'd like
Have better examples for the stub documentation page. Add some examples that would be less theoretical, closer to what we use on a real project.
For instance, the example on stubs uses Spies (which will make people confused if they don't know what a Spy is).

I would be happy to draft something out if you are interested.

Describe alternatives you've considered

Improvements to our docs are welcome. We have been discussing a different take on the API docs as well, more in line with how the Lodash docs work, but that's a huge undertaking not likely to happen anytime soon. Working beats perfect :-)

For extensive tutorial-like examples, we do have the how-to section, which have been in need of expansion for some time.

thanks @fatso83 for the quick feedback. I see the example in the How to Section for stubs is pretty good. If that's ok for you, we will start by proposing a small contribution so we get used to the process (and you can see if that's suitable to your expectations).
I'll be working on it with my friend and colleague @lootster

hi, apology on the delay. I was playing with Sinon and will try to propose some changes by Friday night.
Edit: I found the answer to the below question, I've used an afterEach block.

Quick question: all the things I've tried with Sinon stubs work well, except in one case:
When using Sinon together with Jasmine, I understand that sinon.restore() should always be called before the expect() methods. Otherwise a failure to meet the expect() close will cause the next tests to fail.
However, it doesn't work when my stub throws an Error. I need to do expect() first and restore() after.
This is shown in the code samples I've created here: https://github.com/michaelisvy/javascript-samples/blob/master/src/test-doubles-sinon/stub/song-discount/songWithDiscountService.spec.js

Great thanks,
Michael.

hi @fatso83, I was looking at the code samples in the documentation. I realise that the code samples in the howto section are much better than the ones in the stubs documentation (that is, the stubs link in the documentation section).
However, the howto section is harder to find. Would it make sense to refactor the stubs documentation using some examples inspired from the howto section?
Also, on top of what is in the howto, we could add the following to the documentation:

• show how to restore a stub
• show how to throw an exception from a stub (and handle it)
• show how to check that a stub has been called only once

Please let me know if that makes sense and I'll be happy to work on a pull request.

Regards,
Michael.

hi, I was just wondering if you had any feedback and if you're interested for me to work on a pull request :)

Sure ... I'm a bit swamped with a new family situation and such, so I can't go into specifics on this, but I think there should be room for a kind of introduction to Sinon through various use cases, as you mentioned. But that already exists in many places, and we have linked to several, I believe. You can rip of the best parts and distill it into a PR.
