Background
Suppose a monolithic architecture services needs to migrated to microservices architecture. There are numerous apis for that and many apis data are inter-dependent. Data between the services/apis are exchanged.
Requirements
So to ensure that the microservices apis has data and keys same as of monolithic one and code is capable to intelligent, then there comes numerous scenarios and testcases corresponding to the scenarios.
Challenges
It becomes difficult to manually check all the scenarios or automate from scratch using python or java scripts.
Why Gempyp
Even if you use Python/Java Frameworks to automate the scenarios, you won’t be able to achieve the level of ease of automation, the time saved while automation, performance metrics of the apis, intelligent inter-dependency handling between testcases, data passing between testcases and many more.
As per our data,
Project 1:
Count of Legacy APIs – 150
Count of Current APIs – 200
Total Testcases – 1453
Time Taken to write first testcase – 5 mins
Time Taken to automate the all testcases using Gempyp – 120 hours.
How do we achieve the automation:
API 1: Login API
API 2: Suite API
API 3: Testcase API
Each api has multiple positive and negative scenarios and data is exchanged between them.

</data>Deep diving into features :
1. To achieve inter-dependency between testcases, we use <dependency> tag.
2. To pass data between testcases we create a suite variable(using <post-variables> tag) and use that variable in other testcases.
