How to implement a unit test of a method containing the creation of an instance of SoapClient?

Question

SOAP

Inside my own class, I use SoapClient to exchange data with an external source. To make it more convenient to test, I isolated the creation of an instance of SoapClient in the form of a separate getSoapClient method. Inside it, I create an object of the SoapClient class, passing a certain set of parameters to the constructor, including the url of the external service.

Next, in the code for writing unit tests, I mock the result of the getSoapClient method and everything turns out as it should ... The

question is how to write a unit test for the getSoapClient method itself, which actually consists of one line . I need to check what is fed to the constructor as input exactly the url you want and the correct parameters are used for initialization...
return new SoapClient($url, $params);


On the Internet, everyone says to dig in the direction of dependency injection, but in this case it is inconvenient for me to receive a ready-made object "from outside", plus, anyway, somewhere else in the code, I will need to check its initialization parameters ...

Answer 1

It's a little unclear what exactly you want to test in this method.
This is a typical humble object that does not need to be covered by unit tests. The point is to make such difficult-to-test places as simple as possible and to reduce the probability of error in them to a minimum.
This code can (and preferably should) be verified by an integration or acceptance test, it is outside the scope of unit testing.

and sense to write tests for similar methods-wrappers?
