Data-Driven Testing in Tosca

July 03, 2025

Data-driven testing is a powerful technique that allows you to run the same test case multiple times with different sets of input data. In Tricentis Tosca, data-driven testing helps improve test coverage, reduces duplication, and makes your automated tests more flexible and maintainable.

Whether you’re new to Tosca or looking to enhance your test automation skills, here’s how to implement data-driven testing step by step.

🛠️ What is Data-Driven Testing in Tosca?

Data-driven testing separates test logic from test data. Instead of writing multiple tests for each input combination, you create one reusable test case and feed it data from an external source or Tosca’s TestSheet.

📋 Prepare Your Test Case

Create a reusable test case module for the feature you want to test. For example, if you’re testing a login form:

✅ Parameterize input fields like Username and Password.

✅ Parameterize expected results (e.g., success or error message).

📊Create a TestSheet

Tosca’s TestSheet is where you define different data sets for your test case.

1️⃣ Right-click your test case in Tosca Commander.

2️⃣ Select Convert to Template → your test case becomes a template test case.

3️⃣ Right-click the template and choose Create TestSheet.

4️⃣ In the TestSheet, add columns matching your test case parameters (e.g., Username, Password, ExpectedResult).

5️⃣ Add rows with the different data sets you want to test.

🔗 Bind Data to Your Test Case

Link your TestSheet to your template test case:

✅ Go to your test step values.

✅ Reference the columns from your TestSheet using {=ColumnName} syntax.

For example:

Username → {=Username}

Password → {=Password}

Tosca will automatically create separate test instances for each row in your TestSheet.

🚦 Execute the Data-Driven Tests

When you execute the template test case, Tosca runs it multiple times:

✅ Once for each data row in the TestSheet.

✅ Each execution uses different data, giving you broad test coverage with a single test case.

💡 Tips for Data-Driven Testing in Tosca

✔️ Keep your TestSheets organized—use descriptive column names.

✔️ Store common test data centrally so multiple tests can reuse it.

✔️ Combine data-driven testing with Tosca’s Business Components for scalable test design.

✔️ Use Tosca’s integration with Excel or databases for external data sources if your test data changes frequently.

✅ Conclusion

Data-driven testing in Tosca allows you to build flexible, reusable, and maintainable automated tests with minimal duplication. By converting test cases to templates and linking them to TestSheets, you can cover many scenarios efficiently—saving time and ensuring more reliable software releases.
