Mocking Stripe and AWS APIs in CodeIgniter - php

I have written Integration tests for an application built in CodeIgniter 2.x. The tests are a Selenium + PhpUnit combination.
So far, I have used test accounts of Stripe and Amazon within the application and obviously the tests use the same accounts. I was wondering how would i go about creating Mock objects for these APIs so that i can avoid live data creation/deletion.
For Stripe, i could not find any mocking library for PHP. So stubbing the responses and requests does seem to be a good option. But again, even if i use stubs in my tests in place of real data, the application during that certain integration test will still be needing correct information for it to pass.How do i tell the application to use fake data?
Also, i would like to know if it is generally a good idea to mock objects in integration tests i.e. within the context of web applications?

This is a tool that Stripe themselves have developed for mocking Stripe.
https://github.com/stripe/stripe-mock
It runs a server on your local machine that responds to API calls in s Stripe-like fashion. This would be something you could try for acceptance tests
For PHP Unit tests, you'd be better using something like AspectMock - although config is a bit tricky. You can specify in advance what a call to a Stripe resource (e.g. \Stripe\Stripe::setApiKey, or \Stripe\Customer::retrieve) is supposed to return without hitting the Stripe servers - and you can also test whether or not your application code tried to make these calls. You can also simulate failures to test that your application behaves properly if, say, Stripe is down.

How to unit test certificate exchange in Lumen 5.4

I am working on an API authentication project. Authentication is achieved by adding a client certificate to the https request to the api. Everything works great when I curl to my api using my client certificate and Lumen actually made it trivial to do.
What is not so trivial is unit testing this.
Does anyone know how to make an HTTPS connection in a unit test?
The callSecure method seems to have disappeared since the last version of lumen.
Assuming the HTTPS connection is made - does anyone know how to easily set the certificate. I was hoping I could just get the unit test framework to set up the correct $_SERVER superglobal values so I could use a data provider to send several different certificate errors.
I'd also like to mock the models the controller is injected with so I provide known data in my data providers without having to do any database manipulation.
What I do not want to do is write some methods to make an entire curl request using real certificates.
So - apparently this can not be done as simply as I wanted. In order to test the unit of code in question I have had to add a "getter" to return a copy of the $_SERVER array. In my unit test I then mock the controller object and override the getter to return data I can control. Then rather than using the call method in the test I just directly call the method I am testing.
It has added complexity in terms of having to do more development within the production code just so I can have some tests - however that additional development time will be well worth it in the future.

Trouble Integrating to Visa Direct

My aim is to have an on line system where people can transfer money via visa direct and also pay for the services.
For this I needed to integrate to visa network. However, am having some challenges doing the same.
Well, this is what I have found to be the steps towards integrating with them:
Create a sandbox account where sample code is provided on how you can hit their end point.
My problem came when I found the sample code provided uses PHPUnit hence I have a problem testing on a browser.
The sample code generated for you can only be tested on a terminal via ./vendor/bin/phpunit.. My interest is to be able to test the same on a browser. Can this be done?
After you are done with the tests, you request them to be allowed to move to production.
I am yet to get to this stage since I am stuck at one.
A major concern is that the email provided for communication during the development journey takes days before it is responded. This makes the development journey a bit too long.
Has anyone done this before probably in PHP and would be willing to help me?
Kind regards.
Your work process should be like that:
1- Your code:
You have your webserver and php backend.
2- Visa API:
Download Visa api via Composer.
Test if the api works by itself (isolated from your backend) using phpunit.
After running phpunit, you know your installation of the API is successful. Now you're ready to use it.
Note that the API vendor Visa have already wrote the tests and added phpunit package along with their api, so you just run phpunit.
3- Integration
In your backend, instantiate a Visa API object (I think their API is a class).
Do the function calls as per their API docs.
To write your code, you need to look at API, and use help from their tests and sample codes.
4- Testing
Either use a test suit like phpunit or something else.
If it compiles, it is tested ;) // Don't do that.

PHP: Unit Test For My API

I created an API using SlimeFramework then wrote test to see if results returned from the routes are accurate and also to test side effects of accessing these routes. I am making the client call with guzzle.
I am required to use continuous integration to send the information to travisCI, but travis does not have a host on which I can test my API, and guzzle requires a client(url) from which to make the route calls.
I am new to using any form of continuous integration and do not know what to do. I need help.
How do I test my API on travis?

Unit test bypass for third party web service call

I'm writing function unit tests for a REST API built with Symfony2. Part of the REST API checks HTTP basic authentication against a third party web service.
This presents a bit of a challenge when it comes to unit testing as I can't create a temporary user for the third party web service.
I could hard code credentials in, but I was thinking of an alternative approach. Would it be bad practice to hard code in some logic that shortcircuits the third party API call if the environment is test? Is there a better way to do something like this? I'm sure other applications face this problem.
The best practice is to :
Isolate the authentication against the 3rd party WS in a new class
Make a mock for that class for your tests
Use dependency injection so that for your unit test, you can use your mock

Unit Testing Google OAuth2 with PHP

I'm wondering if there is some way to do unit testing using the Google API for authentication using the Google API PHP Client.
Here is the kind of code example that I want to use around my unit testing case.
(but i want to do more complicated things around it of course that is why i need to do unit testing)
http://code.google.com/p/google-api-php-client/source/browse/trunk/examples/userinfo/index.php
It is messy, but possible. It is not going to be exactly unit testing, but still...
You need to
either write stubs for the parts of your code which do actual
requests to the google api, which would return predefined responses
which your code needs to be ready for.
or create a simple separate
service in your local network which would behave like google api web
service. It is easier than it sounds - a simple php script with a
switch and a readfile(responseFileNumberN)...
Either way you need to decide which of google's behaviours/errors you need to emulate. Testing on live service is a bad idea. This way you are going to test google's api which is out of your control or your network connection, not your app.
