Tosca’s Model-Based Test Automation Explained

Tosca’s Model-Based Test Automation (MBTA) is a modern and efficient approach to test automation that focuses on creating reusable models of applications instead of writing scripts. It’s part of Tricentis Tosca, a leading test automation tool for enterprise applications.

✅ What is Model-Based Test Automation in Tosca?

Model-Based Test Automation in Tosca means:

Testing is driven by models of the application under test (AUT)

These models are created by scanning the UI or API and stored as reusable components

Tests are created by combining and configuring these reusable modules, not by writing code

🧱 Key Components of Tosca MBTA

Component Description

Modules Represent UI elements or API endpoints (buttons, fields, services)

Test Cases Built by combining modules and assigning test data

Test Steps Actions performed on modules (e.g., click, enter text)

Test Data Separated from test logic using TestCase Design

Execution Lists Group of test cases to be executed together

🔍 How MBTA Works in Tosca

1. Scan the Application

Use Tosca XScan tool to scan the UI or API

Create Modules from screen elements (e.g., login button, username field)

2. Create Reusable Modules

Each UI or API component becomes a Module with defined properties and actions

These modules are stored in the Modules folder

3. Build Test Cases

Drag and drop Modules into Test Cases

Add Test Steps by filling in input values and expected results

4. Use TestCase Design (optional)

Create parameterized test cases using templates and combinations

Data-driven testing becomes easy and scalable

5. Execute Tests

Run tests using Tosca Execution Lists

Results are logged in Tosca Commander with screenshots and logs

🎯 Benefits of Tosca’s MBTA

Benefit Explanation

✅ Scriptless No need for code—ideal for business users and testers

♻️ Reusable Components Changes in the app require updates only in modules, not all test cases

⚙️ Fast Maintenance Easier to update and scale tests

📊 Data-Driven Testing Built-in support for parameterization and test case design

🧪 Supports UI & API Unified approach for end-to-end testing

🔄 CI/CD Integration Supports Jenkins, Azure DevOps, etc.

📌 Example: Login Test with Tosca

Scan login page → Create UsernameField, PasswordField, LoginButton modules

Test Case → Add steps using the modules and values (e.g., enter username, password, click)

Test Data → Use TestCase Design for different login credentials

Execution → Run via Execution List and view report

🛠 Tools That Support MBTA in Tosca

Tool Purpose

Tosca Commander Central interface for building and managing tests

Tosca XScan Scans applications to create Modules

TestCase Design For creating parameterized test logic

Tosca ExecutionLists For scheduling and running tests

Tosca CI/CD Integration Automates tests as part of deployment pipeline

🧩 Final Thoughts

Tosca’s Model-Based Test Automation is:

A scriptless, scalable, and maintenance-friendly approach

Well-suited for complex enterprise applications

Ideal for teams looking to bridge the gap between business and IT in test automation
