Mastering Parameterization in TestRigor – A Complete Guide for Test Engineers

TestRigor is a powerful AI-driven automation tool that enables testers to write plain English test cases. One of the most useful features is parameterization, which allows test engineers to reuse tests with different inputs, making tests scalable and maintainable.

🔍 What is Parameterization?

Parameterization means replacing hardcoded values in your test steps with variables or placeholders. These placeholders are filled with real data at runtime, helping you run the same test multiple times with different inputs.

🎯 Why Use Parameterization in TestRigor?

• Reduces duplication of test cases
• Supports data-driven testing
• Makes tests easier to maintain
• Improves test coverage with less effort

🛠️ Method 1: Basic Parameter Declaration

At the start of your test, declare your parameters like this:

parameter email
parameter password

enter "${email}" into "Email"
enter "${password}" into "Password"
click "Login"

During test execution, you can pass different values for email and password.

🧩 Method 2: Using CSV Data Files

Upload a CSV file in the Test Data section:

email,password
user1@example.com,pass123
user2@example.com,pass456

TestRigor will iterate over the rows in the CSV file and apply the data to each test run.

📦 Method 3: Reusable Steps with Parameters

You can define a step (like a function) that takes parameters:

Step name: login with ${email} and ${password}

enter "${email}" into "Email"
enter "${password}" into "Password"
click "Login"

Then use it in a test like this:

login with "admin@example.com" and "admin123"

✈️ Example: Parameterized Flight Booking Test

parameter departure
parameter destination
parameter date

enter "${departure}" into "From"
enter "${destination}" into "To"
enter "${date}" into "Departure Date"
click "Search Flights"

You can test different booking scenarios like:

• From: New York
• To: London
• Date: 2025-06-01

💡 Best Practices

• Use clear and descriptive parameter names
• Group related test data in CSV files
• Define reusable steps for login, search, etc.

🚀 Final Thoughts

TestRigor makes parameterization incredibly easy with plain English syntax. Whether you’re testing login flows or flight booking systems, parameterization helps you scale testing without creating duplicate cases.
