Mastering StudioAssist: Your Essential Guide to Data-Driven Testing and Reusing AI-Generated Test Cases


As a software tester, you constantly look for ways to streamline your workflow and enhance your testing capabilities. StudioAssist, an intelligent feature in Katalon Studio, is designed to make your life easier by automating repetitive tasks and generating efficient test scripts. This blog will serve as your cookbook, providing you with step-by-step instructions on how to harness the full potential of StudioAssist. We'll cover two key use cases: data-driven testing with custom keywords and reusing AI-generated test cases and custom keywords.

The Future of Testing: A Roundtable Discussion on AI and Automation

Data-Driven Testing with StudioAssist

Data-driven testing allows you to execute test scripts with multiple sets of data, making your tests more comprehensive and reliable. Here's how you can generate and reuse a custom keyword with StudioAssist:

Step 1: Generate a custom keyword

Start by navigating to the Script tab. In the Keywords folder, create a new class named MyCustomKeyword.

Prepare a prompt that explains the behavior of your custom keyword in plain language. Here is an example.


Step 2: Generate the code

Highlight your prompt and trigger StudioAssist to generate the code. You can do this by right-clicking and selecting StudioAssist → Generate Code or using the hotkeys Ctrl + Shift + C for Windows or ^ + ⌥ + C for macOS.


Step 3: Review the Generated Keyword

StudioAssist will generate the custom keyword and place it right below your prompt.


Step 4: Execute the script

Now execute the script in Studio to ensure it works as expected.



Reusing AI-Generated Test Cases and Custom Keywords

Reusability is key to efficient testing. StudioAssist enables you to reuse generated custom keywords across different test scripts, saving you time and effort. Here’s how:

Step 1: Prepare Your Prompt

Prepare a prompt that mentions the custom keyword you want to reuse. For example, to reuse the clickElement custom keyword, your prompt could be:

Use the clickElement custom keyword to click on the submit button of the login form.


Step 2: Generate the Test Script

Highlight your prompt and trigger StudioAssist to generate the code, just as you did before.


StudioAssist will generate a test script that incorporates the previously created custom keyword.


Step 3: Execute Your Test Script

Finally, execute your test script to ensure it works as expected. 



Advanced Use Case: Generate Test Data and Perform Data-Driven Testing

In this advanced use case, you'll learn how to generate test data and perform data-driven testing using StudioAssist.

Step 1: Generate Test Data

Prepare a prompt in plain language requesting StudioAssist to generate test data in CSV form. For example:

Generate test data for user login credentials and save it in CSV format.


Step 2: Generate the Code

Highlight your prompt and trigger StudioAssist to generate the code.


Step 3: Execute the Script

Once the script is generated, execute it to create the test data. The data will be saved in the Data File/data.csv inside your project. You can access the data in the Data Files folder.

Step 4: Create Test Data in Katalon Studio

In the Test Explorer, create a Test Data by right-clicking on the Data Files folder and selecting New Test Data. Browse to the generated test data, and it will be loaded into a table.



Step 5: Create a New Test Case

Create a new test case and go to the Data Binding tab. Click Add to bind the test data to your test case. Select the test data you created in the Data Files folder and click OK.


Step 6: Map All Variables

Click Map All to populate the data in the Variable Binding table.


Step 7: Write a Prompt for Data-Driven Testing

Go to the Script tab and write a prompt in plain language to use the test data. For example:

Use the test data to perform a login test for multiple users.


Step 8: Generate the Test Script

Highlight the prompt and trigger StudioAssist to generate the code. StudioAssist will generate a test script using the previously created test data.


Step 9: Execute Your Test Script

Execute your test script to verify it works as expected.
