✅ Tosca TestCase Design: Best Practices for Beginners

TestCase Design in Tosca refers to a powerful feature that helps create data-driven and modular test cases using reusable templates and data combinations. It reduces duplication and improves test coverage.

🔍 Key Concepts in Tosca TestCase Design

Concept Description

TestCase A single automated test scenario

TestCase Template A reusable test structure that can run with different data sets

TestSheet A table of test data combinations (used with templates)

TestSteps Individual actions like click, input, verify, etc.

Modules Represent UI elements or controls scanned from the application

Test Data Data used in TestCases, stored in TestSheets or TestData Management (TDM)

🎯 Best Practices for TestCase Design in Tosca

🔹 1. Use Templates with TestCase Design

Create a template once and link it to a TestSheet.

This allows you to run the same steps with different data combinations, enabling data-driven testing.

🧠 Example: Test a login page with multiple username/password combinations using one template.

🔹 2. Keep TestCases Modular

Break down complex flows into reusable business modules.

Example: Create separate modules for login, search, logout—then reuse across multiple TestCases.

🔹 3. Use Naming Conventions

Follow clear, consistent naming for:

TestCases (TC_Login_Valid)

Modules (Login Page - Username)

Templates (TPL_Login)

TestSheets (TS_LoginData)

🧠 Helps with readability, reusability, and team collaboration.

🔹 4. Link TestSheets Properly

Use drag and drop or link a TestSheet to your TestCase Template.

Make sure the TestSheet columns match the template’s dynamic test step values.

🔹 5. Use Placeholders in Templates

Use ={ColumnName} as placeholders inside templates to map TestSheet values dynamically.

Example:

plaintext

Copy

Edit

Username: Input = {User}

Password: Input = {Pass}

LoginBtn: Click

🔹 6. Avoid Hardcoding Values

Always use test data parameters from TestSheets or Tosca’s Test Data Service (TDS).

Makes tests flexible and easy to maintain.

🔹 7. Validate After Each Step

Use verification steps (e.g., page title, success message) to ensure your app behaves as expected.

🔹 8. Organize TestCases Logically

Structure by:

Feature (e.g., Login, Orders)

Module or Screen

Priority or risk

📁 Use folders and subfolders in Tosca Commander to keep everything clean.

🔹 9. Use ExecutionLists Wisely

Group related TestCases into ExecutionLists for batch execution.

Schedule or prioritize based on business needs.

🔹 10. Review and Reuse

Reuse existing Modules and TestSteps where possible.

Periodically review and refactor TestCases as the application evolves.

🚀 Getting Started Tip:

If you're new to TestCase Design in Tosca:

Start by scanning your app to create Modules.

Build a simple TestCase using drag-and-drop.

Convert it to a Template.

Add a TestSheet with multiple rows of data.

Run and analyze your results in ExecutionLists.
