Executing Pre-steps with karate - karate

In my current middleware integration project, We are using WSO2 API manager tool to manage the API life-cycle.
In test level to access an API I have to create an application and subscribe to the specific API. This can achieved by making a number of rest API requests. I decided to use karate to make these api requests too.
So that part is the pre-steps for my karate test-suite (Or whatever karate tests I execute).
Is there a way to lock down these steps to run before whatever the karate tests I will be executing?

Yes there is, look for karate.callSingle(): https://github.com/intuit/karate#hooks
var result = karate.callSingle('classpath:demo/headers/common-noheaders.feature', config);

I have a Master API exposed which calls microservice A and A then called a third party microservice B. I want to mock Service B [duplicate]

I am exploring Karate API double (mocking) for the integration test. For the below scenarios, I'm not getting the expected mocking response. Your help will be appreciated.
My Setup :
1. Karate Mock Server up with pathMatches rules on port 8001: http://localhost:8001 ( working, validated against "/cat" and some test calls)
2. My own Application is up from docker on port 8080. From Docker exposed 8001 port as well.
Mocking Case:
1. My application REST call exposed to all users http://localhost:8080/service/v1/findUser. This exposed API, underlying calling other REST call http://dev-STG/userservice/v1/findUser which actually giving JSON response. So, I want to mock underlying API call and validate my API behavior accordingly.
Steps tried:
1. Now, in my application config, m replacing actual underlying API call to Karate mock server(http://localhost:8001/userservice/v1/findUser). Then did build & up my application docker.
In Karate, I defined test e.g "testIntgrtn.feature" which calling my application API "http://localhost:8080/service/v1/findUser" and Karate mock server up and set with pathmatch "/userservice/v1/findUser".
After executing "testIntgrtn.feature" karate not mocking for an underlying call(http://localhost:8001/userservice/v1/findUser).
Now, in "testIntgrtn.feature" file I changed my-application URL to underlying REST URL i.e (http://localhost:8001/userservice/v1/findUser) then mocking will work like charm.
I'm not understanding why underlying API call not getting mocked here? Did I miss something here?
Also, in Karate can we monitor all REST calls (like cypress mocking).
Thanks for this wonderful framework. Which is intuitive for writing automation cases.
Karate cannot automatically intercept calls.
The recommended approach is when you boot the application running at localhost:8080 you change the configuration so that instead of calling http://dev-stg/userservice/v1/findUser it calls something like http://localhost:8001/v1/findUser. This is what most teams do, and is easy because you should anyway be defining external URL-s as application.properties (or equivalent) as a best-practice.
It is very easy to over-ride an application property in Spring Boot for example, you can do this via the command-line: https://stackoverflow.com/a/37053004/143475
If you want, you can dynamically provision a port for the mock. So your unit test can first start a mock, get the port, and then start the server. You can find details in the Karate documentation.
All this said, if you are able to change the (system) HTTP proxy before the app at localhost:8080 starts, you may be able to do this without modifying the configuration. (But it is tricky, so I recommend the approach explained above.) So in this case, Karate can actually "intercept" the outgoing HTTP calls that the app at localhost:8080 makes.

How to test Web Services with Elixir?

We have a couple of REST APIs that need to be tested. APIs are owned by some other team. Currently, we use Node.js with Ava to test our APIs.
We have recently started exploring Elixir as our scripting language. We would like to experiment with Elixir to test REST API. The question here is - how to test external web services/REST API with Elixir?
Every Google search around Elixir testing refers back to ExUnit which is basically for unit testing of Elixir apps. We don't have any app written in Elixir or in Phoenix.
All we want to do is to test API end-to-end. How to do that with Elixir? Which libraries to use? I know I can make network calls from my tests written in ExUnit and verify the API behavior, but not sure if it is the right way.
NOTE: We already have JMeter in place for load testing of API but we wish to keep functional testing separate from load testing due to complex workflows involved with API.
I think what you descried in the answer is the right way.
You can use ExUnit as the test running and reporting framework. In ExUnit you can do whatever you want, make network calls, even parse the DOM. For testing a REST API you can use HTTPoision and assert on status code and response body.
Create a new mix project
mix new api_test
Add HTTPoison dependency to mix.exs
...
defp deps do
[
{:httpoison, "~> 1.6"}
]
end
...
Run mix deps.get to get HTTPoison installed.
Add a test in test/api_test_test.exs
defmodule ApiTestTest do
use ExUnit.Case
doctest ApiTest
test "API alive" do
resp = HTTPoison.get!("https://api.github.com")
assert resp.status_code == 200
end
end
Run the tests with mix test from the project root.

How to stub an API when testing with Selenium Server

I'm using Nightwatch.js to test a MERN stack application—it makes calls to the Twilio API when it receives a POST request at /sms/outgoing/.
I would rather not send SMS messages every time I run my e2e tests—instead I'd like to stub out the behaviour and, ideally, return the request data, so that I can check my app is submitting the correct info.
I have looked at libraries such as nock and fetch-mock, but neither of these will work with tests that rely on selenium.
Is there a library that can intercept requests made by Selenium Server and provide the stubbing behaviour I'm after?
As you have mentioned nock and fetch-mock, I assume you're using a node server?
If that is the case, you could modify the server to detect an environment variable process.env.MOCK_API and return hard-coded responses to fetch request using fetch-reply-with

Retrieve response object after UI action?

so I've created several service tests where I validate the response object, normally using the requests library or http library to send a POST request for example.
This time however I'm doing an end-to-end test. Through the UI progressing through a workflow, one stage involves uploading a document, behind the scenes this will call a separate service, the response of which will contain some information that could be useful to me for further verification.
Is there a way to merge these? After the UI action can I 'listen' for the response object somehow?
I do NOT wish to call the endpoint directly as I want to prove the workflow is as intended, the endpoint is verified directly in service level tests already.
Integrate Selenium tests with BrowserMob Proxy and you will be able to 'listen' for the responses using HAR file:
