Hello Nidhi,
Basically in order to create tests’ suite you need to create a driver test which will contain calls from all your external test cases, this feature is only available in the ZAPTEST Enterprise Edition – Please check the differences between ZAPTEST Free and Enterprise Editions at:
https://www.zaptest.com/get-started?free-trial
In the ZAPTEST Free Edition you can only create a single test, this test can contain all your test cases’ steps, but please note that in the Free Edition you’ll be able to use only 3 rows of Datatable.
Thanks,
ZAPTEST Team
