How to Efficiently Share Test Data Across Multiple Test Cases in Katalon Studio?

Miscellaneous

Hi everyone :waving_hand:,

I’m currently building a fairly large-scale test suite in Katalon Studio and I’m looking for the best practices to share and manage test data across multiple test cases efficiently.

Specifically, I’m wondering:

What’s the recommended way to pass dynamic test data between different test cases without hardcoding or relying heavily on global variables?

Is there a clean way to use Test Data files or Data Files binding for multiple test cases within a single Test Suite Collection?

Are there any working examples or patterns that scale well with TestOps integration or CI/CD pipelines?

I’d appreciate if anyone could share some real-world examples or approaches that helped keep things organized, maintainable, and reusable.

Thanks in advance for your help!

Q1. Why do you want to avoid Global Variables? Please describe the reason.

Q2. Do your Test Case/TC1 and TC2 read-only the data externally given to the project? Or, does your TC1 dynamically update the data and TC2 wants to refer to the updates?

Q3. Katalon offers a feature named “Data-driven testing” as described at Data-driven testing with Katalon Studio | Katalon Docs. Why don’t you use it? Anything unsatisfactory for you? Please describe what you find insufficent.

If you are looking for best practices and recommendations. I would suggest to use all the differents parametrization features.

In short words, I ofter use this approach:

  • For variables that would be used in a lot of test cases: I use Global Variables grouped by different execution profiles depending on the environment / scenarios i want to test.
  • For variables that will only be used inside a Test cases or for those tests scenarios when a mayor (main) test cases calls other test cases (childs) inside: I use Test Case Variables and I share the information from the mayor test case through the childs test cases using the test case parametrization feature.
  • If I have to deal with some kind of loop with different information required, such as Data-Driven tests scenarios: I use Test Cases variables and a Data File, using the Data Binding feature at a Test case or test Suite level, depending on what i want to achieve.

So, as you can see, It depends on what you aim to achieve I guess. If you share more information about you test cases maybe we can give you more recommendations.

Bests,
