Lets say I have one api and there are different scenarios to check in that one api.So for this can we add different scenarios in one feature file without calling api again and again.
You can certainly have multiple scenarios in one feature file.
And if you get a response back and you can do all the assertions you have in mind against this single response - you don't need to call again. Maybe you need a single scenario.
If you are expecting all your boundary conditions and non-happy paths to be achieved without making multiple HTTP calls, I'm sorry - I don't think any framework will do that magic for you.

I know that GET is used to retrieve data from the server without modifying anything. Whereas POST is used to add data. I won't get into PUT/PATCH, and assume that POST is always used to update and replace data.
The theory is nice, but in practice I have encountered many situations where my GET calls need to be replaced with POST calls. This is because the response often gets incorrectly cached. Where I work there are proxy servers for security, caching, load balancing, etc., and often times the response for GET calls is directly cached to speed up the call, whereas POST calls never get fully cached.
So for my question, if I have an API call /api/get_orders/month. Theoretically, this should be a GET call, however, the number of orders might update any second. So if I call this API at any moment it may return for example 1000, and calling it just two seconds later should return 1001. However, because of the cache, and although adding a version flag such as ?v=<date_as_int> should ensure that the updated value is returned, there seems to be some caches in the proxy servers that might ignore this.
Basically, I don't feel safe enough using GET unless I know for certain that the data will not be modified or if I know for a fact that the response is always the updated data.
So, would you recommend using POST/GET in the case of retrieving daily/monthly number of orders. And if GET, with all the different and complex layers and server set-ups, how can one be certain that the data is always updated?
If you're doing multiple GET request and something is caching the data in between, you have no idea what it is or how to change it's behavior then POST is a valid workaround.
In any normal situation you would take the time what sits in between your browser and your server, and if there's something that's behaving in a way that doesn't make sense, I would try to investigate and fix that.
So you work at a place where some of that infrastructure exists. Maybe talk to the people that maintain it? But if that's not an option and you just want to find the 'ignore every convention and make my request work'-workaround, then you can use POST.
I am currently working on a REST API for a project. In the process I should search for events. I would like to make an endpoint for searching events in a period. That is, specify two parameters with from - to.
For the search you normally take a GET operation. My question is now it makes sense to specify two parameters in the path or should I rather fall back to a POST operation for something like that.
Example for the path /Events{From}{To}
Is this even feasible with multiple parameters?
If you are not making a change on the resource, you should use GET operation.
More detailed explanation:
If you were writing a plain old RPC API call, they could technically interchangeable as long as the processing server side were no different between both calls. However, in order for the call to be RESTful, calling the endpoint via the GET method should have a distinct functionality (which is to get resource(s)) from the POST method (which is to create new resources).
GET request with multiple parameters: /events?param1=value1¶m2=value2
GET request with an array as parameter: /events?param=value1,value2,value3
I am working on API testing project. My requirement is to use response of one API as a response of another. I need different Feature files for each API. The challenge was to use output of one API as input to another which in my case is output of one feature file as input of another.
Also i don't want to call one feature file in another. So to achieve this currently we are using Runner class to initiate the test and using Properties file to store the responses. In the same run we are reading these properties file which act as input to another API(Feature file).
Is there any other better way to do this since we are not willing to use properties file in the framework.
Thanks
I think you are over-complicating your tests. My advice is combine the 2 calls into one scenario. Else there is no way unless you call a second feature file.
Does karate provide any listener support where I can intercept any specific things like rest calls?
This is more like added customization we want to perform apart from what the karate provides. There will be always something or other we need to customize based on the need.
Say that I have 10000 test cases running in parallel and using karate parallel runner I get a nice report with the time it takes for each step and test cases. One of my service is getting called multiple times and I wanted to know what is the average time the service takes out of all the calls. What is the maximum or minimum time it takes.
I think Karate Hooks will get you what you need - if you write a function to aggregate the responseTime.
I'm willing to look at introducing this feature if needed, but you'll have to make a proposal on what the syntax should look like. Feel free to open a feature request. Today we do have configure headers that is like a "before" for all requests. Maybe something along those lines.
For a RESTful API that I'm creating, I need to have some functionality that get's a resource, but if it doesn't exist, creates it and then returns it. I don't think this should be the default behaviour of a GET request. I could enable this functionality on a certain parameter I give to the GET request, but it seems a little bit dirty.
The main point is that I want to do only one request for this, as these requests are gonna be done from mobile devices that potentially have a slow internet connection, so I want to limit the requests that need to be done as much as possible.
I'm not sure if this fits in the RESTful world, but if it doesn't, it will disappoint me, because it will mean I have to make a little hack on the REST idea.
Does anyone know of a RESTful way of doing this, or otherwise, a beatiful way that doesn't conflict with the REST idea?
Does the client need to provide any information as part of the creation? If so then you really need to separate out GET and POSTas otherwise you need to send that information with each GET and that will be very ugly.
If instead you are sending a GET without any additional information then there's no reason why the backend can't create the resource if it doesn't already exist prior to returning it. Depending on the amount of time it takes to create the resource you might want to think about going asynchronous and using 202 as per other answers, but that then means that your client has to handle (yet) another response code so it might be better off just waiting for the resource to be finalised and returned.
very simple:
Request: HEAD, examine response code: either 404 or 200. If you need the body, use GET.
It not available, perform a PUT or POST, the server should respond with 204 and the Location header with the URL of the newly created resource.
