[JVM ]Cross Browser Testing using Cucumber

[Kunal Mehta]

Hello All,

I want to run Cucumber JVM test on list of browser on single instruction. I have set up my code structure using this article. (adding Modules & Logging)

My requirement is to build and run selected test\s on configured browser\s and execute them on CI\local environment.Currently I am using Junit and MVN. I am using SharedDriver (Dependency Injection via PICO) way of opening and closing browser.

As logging was becoming another hassle in multi threading environment, I am flexible if on execution all the test are run on single browser first and then pick up the next browser in sequence. Any reference to git repo will really help.

I really appreciate if any body can assist or direct me to sources.

Thanks

Hello wonderful people,

wish you all a very happy new year.

any leads on this post is more than appreciated.

AFAIK, Cucumber isn't intended to be a cross browser testing tool.

I just want to understand how teams already using cucumber JVM are coping up with cross browser testing. There must be a way of saving time by running test in parallel.

Thanks

Without getting into the specifics of CucumberJVM, since I've only done this in Ruby myself, the general approach I've used is this...

1. Choose a main browser for testing the overall behavior of my app. I usually prefer a headless browser for this for speed. Use this most of the time when I run Cucumber on my dev machine.

2. Tag scenarios that are likely to expose differences between browsers.

3. Allow the browser driver to be chosen via a configuration setting of some sort, e.g. an environment variable or maybe through Maven. 

4. Run the tagged scenarios with other browsers as needed on my dev machine and regularly on a CI machine.

A few important things to note here:

1. Cucumber doesn't care about browsers. All the browser-related stuff goes in your own code in step defs, hooks, etc.

2. You'll do a separate run of your Cucumber scenarios for each browser. 

3. Not every scenario is worth running in every browser, especially if you're good about keeping scenarios that test non-UI behaviors from touching the UI. 

Hope that helps,

Richard

Thanks Richard, each point is worthy enough.

Currently I am already picking up browser from properties file. properties file exist in .gitignore too, which saves me from any confusion , whilst running\pushing test on CI.

Locally I keep toggling between browser. this approach works well for few test but in that case too I want some mechanism by which I can log each browser log4j logs in different file.

On the other thoughts, would it be good idea to run test on each browser overnight on CI build. The test & browser can be managed by the time of test run.

Thanks again for your valuable suggestion.

Hi Kunal,

We used Gradle tasks to switch browsers, the Gradle task setting an environment variable for the browser and environnent, eg

gradle testDevFirefox

Then we had a Bamboo setup that executed separate tasks for each browser, triggered by a change in the test of Dev codebase. Each Bamboo track ran in a separate AWS instance, executing a Gradle task each.

Hope this helps,

Nick

Hi Kunal,  

Hope you are doing good. I want to  know if we can implement cross browser testing using cucumber . it would be really great if you take few minutes to help me out.

I have a feature file and i want to execute that feature file parallel in all the 3 browser ie, chrome, firefox.....i am using cucumber with maven. Can i please know if there is a way to get that done.

thanx in advance
