I was having problem with learning cucumber from other sources. But the way you explain i didnt have any problem understanding. It feels like i found my source of learning all things from you. Thank you very much for working so hard to teach others.

Hi Raghav, I have watched and recommend this playlist to all my friends and must say its really helpful and easy to understand through your videos. I have one question, can I parameterize rows with no fix column? Such as in 1st row there are 5 column and and in second only 4 and so on. Can I do it using Scenario Outline?

Thank you very much Raghav, thoroughly explained.
could you please make videos for
1. data driven testing using properties file as an input
2. how to test sqls/unix commands in cucumber.
3. how to test soap/rest API's using cucumber.

it would be a great help:)

Thank you Raghav, u made us very simple to learn...please make video on how to handle Multiple Feature files with different combinations in reality and how to handle Datatables with Maps

[nagay]

Nice explanation, glad that I found your videos on many topics - very clear and you make them so simple to remember. great effort and keep going and help all the curious learners.
Have one question, as here passed 2 sets of data, but if we have multiple sets of data(may be 100 sets) then how to parameterize. Should we use a third party file like .xls or .xslx. If so then how to read the data from the file.

Thanks, Raghav for very well explained the Parameterization and Data-Driven Testing. Can we use data files i.e CSV, Excel, and database(Oracle.etc) instead of mentioned data details in the feature files? If yes could you please add that video in near future?

Hi Raghav,

As always, thanks for the tutorial. I've followed this tutorial and saw some exceptions as I switched to use gecko/FireFox (geckodriver-v0.27.0-win64 and Firefox 81.0 64 bit).
For any scenario, at the final step I see the exception:
" Browsing context has been discarded"


Here is the exception from Eclipse terminal:

Thank u Raghav...This is an amazing video for beginners

[seymavural]

At 8:31, line 41, you said put (.*) for a string. What is the difference between {string} and (.*)? My eclipse didn't run on (.*) (MAC computer)

[supriyassampath]

Thank you so much sir, it's very easy to understand the way you explain.
Words fall short to thank you for this service.
I jus wanted to ask you can we implement in the same way in real time too?
