I am running Karate UI tests that are kicked off from a spring boot application, which works fine. However, if the driver fails, karate appears to be killing the whole process. I saw that System.exit() is used in different places in the Karate API. Is there a strategy for avoiding Karate getting killed of with System.exit()? Must I create custom code that doesn't include System.exit()? Any suggestions?
Thanks,
Chris
Completely agree that System.exit() is not-ideal, I remember that it made sense in the "fat jar" - so is that what you are using?
The best thing you could do is submit a PR or at least suggest which part of the code comes into play for your case. Karate certainly has not been designed to be kicked off from a web-app, so yes - this may need some investigation.

I am developing WebUI automation tests using Karate 0.9.5.RC5 and it is working wonderfully. Does anyone know how to execute performance testing in Karate for WebUI Automation tests?
That's great to hear and thanks for the feedback. To be honest, we have focused on API perf testing and UI functional test automation so far. Maybe you can help us by experimenting and sharing what you find.
You must be aware of the Gatling integration for API performance testing. So we have some pieces of the puzzle in place.
So maybe a hybrid strategy is best:
identify the API calls being made by the UI, in the future we would like to derive them automatically from the Chrome network / devtools
manually convert the API calls to Karate tests, note that the VS Code plugin has an option to import from cURL
now you can convert the Karate tests to a performance test, and for most teams, this is sufficient
if needed, you can add some Karate calls to load HTML and static resources to make the load profile more realistic
finally, it may be possible to run a Karate UI test in parallel, just to measure "real user" experience and measure the HTML / JS load times etc on the browser side. we don't have this in place yet, but it should be possible to get all the page timings and perf-stats from Chrome
potentially you could look at spinning up multiple Chrome instances in parallel using Docker - but again, this is something yet to be explored

This is my first time playing with cucumber and also creating a suite which tests and API. My questions is when testing the API does it need to be running?
For example I've got this in my head,
Start express server as background task
Then when that has booted up (How would I know if that happened?) then run the cucumber tests?
I don't really know the best practises for this. Which I think is the main problem here sorry.
It would be helpful to see a .travis.yml file or a bash script.
I can't offer you a working example. But I can outline how I would approach the problem.
Your goal is to automate the verification of a rest api or similar. That is, making sure that a web application responds in the expected way given a specific question.
For some reason you want to use Cucumber.
The first thing I would like to mention is that Behaviour-Driven Development, BDD, and Cucumber are not testing tools. The purpose with BDD and Cucumber is to act as a communication tool between those who know what the system should do, those who write code to make it happen, and those who verify the behaviour. That’s why the examples are written in, almost, a natural language.
How would I approach the problem then?
I would verify the vast majority of the behaviour by calling the methods that make up the API from a unit test or a Cucumber scenario. That is, verify that they work properly without a running server. And without a database. This is fast and speed is important. I would probably verify more than 90% of the logic this way.
I would verify the wiring by firing up a server and verify that it is possible to reach the methods verified in the previous step. This is slow so I would do as little as possible here. I would, if possible, fire up the server from the code used to implement the verification. I would start the server as a part of the test setup.
This didn’t involve any external tools. It only involved your programming language and some libraries. The reason for doing it this way is that I want to to be as portable as possible. The fewer tools you use, the easier it gets to work with something.
It has happened that I have done some of the setup in my build tool and had it start a server before running the integration tests. This is usually more heavy weight and something I avoid if possible.
So, verify the behaviour without a server. Verify the wiring with a server. It is important to only verify the wiring in this step. The logic has been verified earlier, there is no need to repeat it.
Speed, as in a fast feedback loop, is very important. Building and testing the entire system should, in a good world, take seconds rather than minutes.
I have a working example if you're interested (running on travis).
I use docker-compose to launch the API & required components such as database, then I run cucumber-js tests against the running stack.
docker-compose is also used for local development & testing.
I've also released a library to help writing cucumber for APIs, https://github.com/ekino/veggies.
I am using Cucumber-JVM for my functional automated testing. Underneath code is selenium-java.
My application uses google authentication. If I have 50 tests in my suite and I run my tests, sometimes I face CAPTCHA in login steps and all my tests start failing.
One way to solve this problem forever is if somehow I mock/setup login using cookies or if I retain the browser session.
I know retaining the browser session could result in other different problems and it is always recommended to start your tests from clean browser tests.
Has anyone ever faced this issue and can help me with this? What may go wrong if i use same browser session for all my cucumber scenarios?
I think the best approach would be to work with your developers and deploy this application without Captcha on your test environments. That would be the cleanest way to get things done.
Your approach:
Pros:
Less execution time (no login needed)
quick and dirty fix
Cons:
quick and dirty fix
What happens when your session expire? All your test will fail again...
You'll have to setup a browser profile with a specific session. What if you're testing on 5 different browsers?
In my current project we are testing our ASP.NET GUI using WatiN and Mbunit.
When I was writing the tests I realized that it would be great if we also could use all of these for stresstesting. Currently we are using Grinder to stresstest but then we have to script our cases all over again which for many reasons isent that good.
I have been trying to find a tool that can use my existing tests to create load on the site and record stats, but so far i have found noting. Is there such a tool or is there an easy way to create one?
We have issues on our build server when running WatiN tests as it often throws timeouts trying to access the Internet Explorer COM component. It seems to hang randomly while waiting for the total page to load.
Given this, I would not recommend it for stress testing as the results will be inaccurate and the tests are likely to be slow.
I would recommend JMeter for making threaded calls to the HTTP requests that your GUI is making
For load testing there is a tool which looks promising - LoadStorm. Free for 25 users. It has zero deployment needs as this is a cloud based service.
You could build a load controller for your stress testing. It could take your watin tests and run them in a multithreaded/multiprocessed way.
If you are comfortable using Selenium instead of WatiN, check out BrowserMob for browser-based load testing. I'm one of the Selenium RC authors and started BrowserMob to provide a new way to load test. By using real browsers, rather than simulated traffic, tests end up being much easier to script and maintain.
