What Are Tosca Test Cases and How to Create Them

In the world of test automation, Tosca by Tricentis is a powerful tool that allows teams to automate tests efficiently across different technologies and platforms. One of the core components of Tosca is the test case—a structured sequence of steps designed to validate application functionality.

In this blog, we’ll explain what Tosca test cases are, how they work, and walk through the steps to create them effectively.


What Are Tosca Test Cases?

A Tosca test case is a sequence of reusable and modular steps that simulate user interactions or system operations to validate the behavior of an application. Each test case consists of various components like test steps, test data, and business logic to ensure the application behaves as expected under different conditions.

Unlike traditional code-based test automation frameworks, Tosca uses a model-based approach. This means testers do not need to write code. Instead, they work with graphical interfaces and reusable modules, making automation faster and more accessible.


Key Components of Tosca Test Cases

  1. Modules: Reusable building blocks created by scanning the application under test. Each module represents a UI element (like buttons, input fields) or a technical function.
  2. Test Steps: Actions taken on the application, built using the scanned modules. Each test step corresponds to an interaction, like entering text or clicking a button.
  3. Test Case: A container that organizes a sequence of test steps to perform a specific verification.
  4. Test Data: Parameters used in test steps to support data-driven testing.
  5. Test Configuration Parameters: Custom settings to control the behavior of tests across different environments or conditions.


How to Create a Test Case in Tosca

Step 1: Scan the Application

Use Tosca’s Scan feature (Tosca XScan) to explore the user interface of the application and identify elements to automate. This process generates Modules that are stored in the Tosca repository.


Step 2: Create a Test Case

  • Right-click the TestCases folder and choose Create TestCase.
  • Name your test case according to its purpose, such as LoginFunctionalityTest.


Step 3: Add Test Steps

  • Drag the relevant modules from the Modules section into your test case.
  • Each module will create a test step that simulates a user action.

Example:

  • Drag the Username module and set the value (e.g., test_user).
  • Drag the Password module and set the value.
  • Drag the Login Button module to simulate a click action.


Step 4: Parameterize Test Data

Use TestCase Variables or TestSheets to parameterize the test inputs. This enables data-driven testing, where the same test case runs with different sets of data.


Step 5: Add Validations

After performing actions, you can validate outcomes by using verification steps. For example, check if the dashboard page is displayed after login.


Step 6: Execute the Test Case

Run the test case using Tosca Commander or Tosca ExecutionLists. You can also schedule or trigger tests as part of a CI/CD pipeline.


Benefits of Tosca Test Cases

  • No scripting required: Ideal for non-programmers.
  • Reusable modules: Saves time and reduces duplication.
  • Data-driven testing: Supports broad test coverage.
  • Integration-ready: Works well with CI/CD tools like Jenkins, Azure DevOps.


Conclusion

Tosca test cases are central to efficient, scalable test automation using the model-based testing approach. They make it easy to build, manage, and reuse automated tests with minimal coding, while ensuring high test coverage. By learning how to create and optimize Tosca test cases, QA teams can significantly improve their testing speed, accuracy, and agility in fast-paced development environments.

Tosca vs Selenium: Which One to Choose?

Choosing the right test automation tool can make or break the efficiency of your QA process. Two widely discussed tools in the test automation space are Tosca by Tricentis and Selenium, the open-source web automation framework. While both tools aim to automate testing and accelerate software delivery, they cater to different needs and teams. In this blog, we’ll provide a comprehensive comparison between Tosca and Selenium to help you decide which one suits your project best. Overview Selenium is an open-source framework primarily used for automating web applications. It supports multiple languages (Java, Python, C#, etc.) and browsers, making it ideal for custom, flexible automation solutions. Tosca, on the other hand, is a commercial test automation tool that supports model-based testing, API testing, mobile, desktop, and even SAP testing. It's designed for enterprise-grade testing with minimal scripting. Key Comparison: Tosca vs Selenium Feature          ...

Flask API Optimization: Using Content Delivery Networks (CDNs)

When building APIs with Flask, performance and speed are key metrics that directly affect user experience and application scalability. One powerful but often overlooked way to enhance these metrics is through the use of Content Delivery Networks (CDNs). While CDNs are traditionally associated with delivering static assets like images, CSS, and JavaScript, they can also play a significant role in optimizing your Flask-based APIs. What Is a CDN? A Content Delivery Network is a globally distributed network of proxy servers that cache content closer to end-users. Instead of every user hitting your central Flask server, a CDN enables them to access cached responses or assets from a nearby server, significantly reducing latency and improving response times. Benefits of Using CDNs with Flask APIs 1. Reduced Latency Latency is the time it takes for a request to travel from the client to your server and back. By caching static or semi-static responses at edge locations, CDNs reduce the distance...

Using ID and Name Locators in Selenium Python

When automating browser tasks with Selenium in Python, one of the first challenges is identifying and interacting with web elements. Selenium offers multiple strategies for locating elements, and two of the simplest and most effective methods are using the ID and Name locators. These locators are fast, reliable, and easy to use, making them ideal for beginners and experienced testers alike. In this blog post, we’ll dive into how ID and Name locators work in Selenium Python, provide examples, and share best practices to help you write clean and maintainable test scripts. What Are Locators in Selenium? Locators in Selenium are methods used to find elements on a web page. Selenium supports several locator types, including: ID Name Class Name Tag Name Link Text CSS Selector XPath Among these, ID and Name locators are often the most efficient because browsers optimize them for speed and accuracy. Setting Up Selenium with Python Before using locators, ensure you have Selenium installed: bash...
