TOSCA Automation Tutorial: Mastering the Model-Based Testing Approach

Introduction

In today’s fast-paced digital world, businesses are rapidly moving towards automation to improve software quality and reduce time to market. Test automation plays a vital role in achieving this goal, and one of the most powerful tools in the market is TOSCA. This tutorial focuses on the model-based approach of TOSCA Automation, offering valuable insights for professionals seeking TOSCA Training Online, enrolling in a TOSCA Testing Course, or pursuing TOSCA Automation Certification.

Model-based test automation is a game changer, making testing more efficient, less code-dependent, and easier to maintain. In this blog, we will walk you through the fundamentals of TOSCA, explain its model-based testing approach, and show you how to apply it in real-world projects.

What is TOSCA?

Overview

TOSCA (Topology and Orchestration Specification for Cloud Applications) is a test automation tool developed by Tricentis. It supports end-to-end testing across various platforms, including web, mobile, API, and desktop applications. What sets TOSCA apart is its model-based testing methodology, which eliminates the need for scripting and simplifies test case creation.

Why TOSCA?

• Scriptless automation with reusable components

• Support for a wide range of technologies

• Seamless integration with CI/CD tools

• Robust reporting and analytics

• Efficient test data management

According to a recent World Quality Report, 44% of organizations find it difficult to maintain test scripts. TOSCA's model-based approach directly addresses this pain point by removing the dependency on traditional scripting.

Understanding the Model-Based Testing Approach in TOSCA

What is Model-Based Testing (MBT)?

Model-Based Testing (MBT) in TOSCA refers to the technique of creating a model of the application under test (AUT) and using it to generate test cases automatically. It emphasizes building business-relevant models instead of focusing on technical scripting.

Key Components of MBT in TOSCA:

1. Modules

Modules are the reusable components representing elements in the AUT. For example, a login button or an input field. TOSCA scans the application and creates these modules for you.

2. Test Cases

Test cases are built using the modules. Testers drag and drop modules into a test case and define the required data.

3. Test Case Design (TCD)

This feature allows testers to create multiple test scenarios by separating test logic and test data.

4. ExecutionLists

Used for organizing and running test cases. You can set execution conditions, schedule tests, and track results.

5. Reusability and Maintainability

Since modules and test steps are reusable, any change in the application requires minimal updates.

Benefits of Model-Based Testing

• Faster Test Development: Build test cases quickly with reusable modules

• Lower Maintenance: Update one module and reflect changes across all test cases

• Improved Test Coverage: Easily manage a wide range of test scenarios

• Collaboration Friendly: Business analysts and testers can collaborate easily due to scriptless design

Setting Up TOSCA for Model-Based Testing

Step 1: Install TOSCA

• Download the latest version from Tricentis website

• Complete the installation wizard

Step 2: Scan the Application

• Launch the TOSCA XScan tool

• Navigate through the application

• TOSCA captures UI elements and creates modules automatically

Step 3: Create a Test Case

• Go to the Test Case section

• Drag modules from the Module folder

• Define input values and expected results

Step 4: Design Test Data

• Use the Test Case Design section

• Define attributes and link them with test cases

Step 5: Execute and Analyze

• Add test cases to ExecutionList

• Run them directly or schedule execution

• Analyze results in the Execution Log

Real-World Example: Login Test Case

Let’s take a practical scenario to solidify our understanding of the model-based approach.

Application: Web-Based Login Page

Step-by-Step Guide:

1. Scan the Page

• Use XScan to capture Username, Password, and Login Button

2. Create Modules

• Username_Field

• Password_Field

• Login_Button

3. Design Test Case

• Drag all three modules into a test case

• Enter valid credentials

• Add verification for successful login

4. Design Test Data

• Define valid and invalid credentials

• Link data to the test case

5. Execute Test

• Add to ExecutionList

• Run and analyze results

Outcome

This process helps reduce errors, saves time, and ensures maintainability of the test case.

TOSCA Test Case Design: Advanced Concepts

Equivalence Class Partitioning

TOSCA allows creating test cases for different data combinations using Equivalence Class Partitioning (ECP). It ensures comprehensive testing with fewer test cases.

TestSheet Linking

Link attributes in the TestSheet to corresponding values in the test case. This promotes a data-driven testing approach.

Constraints and Combinatorial Methods

TOSCA supports constraints to eliminate invalid combinations. You can also choose between different combinatorial methods like All-Pairs to optimize your test coverage.

Integrating TOSCA with DevOps

CI/CD Integration

TOSCA supports integration with Jenkins, Azure DevOps, Bamboo, and other tools. You can schedule tests as part of the build pipeline.

API Testing

TOSCA also provides robust support for API testing. You can scan APIs, define request/response, and validate them using the same model-based approach.

Version Control

TOSCA integrates with Git, allowing teams to version control their test cases and modules.

Reporting and Analytics

TOSCA’s dashboard provides real-time insights. You can view pass/fail status, execution trends, and defect reports directly.

TOSCA Automation Certification: Why It Matters

Getting certified in TOSCA validates your skills and makes you more employable. It proves your understanding of model-based testing and ability to implement it effectively.

Popular Certifications:

• Tricentis Certified Automation Specialist

• Tricentis Certified Automation Engineer

Benefits of Certification:

• Increased job opportunities

• Higher salary packages

• Recognition in QA communities
