Creating Test Steps and Test Step Values in Tosca

Tricentis Tosca is a popular test automation tool that enables teams to perform model-based testing across web, desktop, API, and mobile applications. One of the core concepts in Tosca is the use of Test Steps and Test Step Values, which form the foundation of how test cases are designed and executed.

In this blog post, we’ll explore what Test Steps and Test Step Values are, how to create and configure them, and best practices to make your test automation more maintainable and efficient.


What are Test Steps in Tosca?

A Test Step in Tosca represents a single unit of action or verification within a test case. It can be anything from clicking a button, entering text into a field, or validating a message on the screen. Each Test Step uses a Module (a reusable component created during scanning) and defines how that module is used in a specific test.

Modules in Tosca are like blueprints of UI or API elements that have been scanned from the application under test. When you add a Module to a test case, it becomes a Test Step.


What are Test Step Values?

Test Step Values define what action the test should perform or what value should be verified for each control (field, button, label, etc.) in the Test Step. Each control in the module becomes a Test Step Value in the test step.

Depending on the type of interaction, you can:

  • Input data (e.g., enter a username in a text field).
  • Verify values (e.g., check if a label contains a specific message).
  • Perform actions (e.g., click a button or select an item from a dropdown).


Creating Test Steps in Tosca

Here’s how to create Test Steps in Tosca:

  1. Scan the Application: Use Tosca’s Tosca XScan tool to scan your application and create Modules.
  2. Create a Test Case: Right-click a Test Case folder and select Create TestCase.
  3. Add a Module to the Test Case: Drag and drop a Module onto your Test Case. Tosca will automatically create a Test Step with all the controls as Test Step Values.
  4. Edit Test Step Values: Enter the desired data or verification values into the appropriate fields.

Example:

Suppose you’re automating a login page with two fields (Username, Password) and a Login button.

  • The Module will contain three controls: Username, Password, and Login.
  • In the Test Case:

  1. For Username, enter a value like testuser.
  2. For Password, enter password123.
  3. For Login, set the action to Click.


Types of Actions in Test Step Values

You can define various actions using the ActionMode:

  1. Input: Enter or send data to a field.
  2. Verify: Check that a value matches an expected result.
  3. Buffer: Save a value for later use.
  4. Select: Choose from a dropdown or list.
  5. Click: Simulate clicking a button or link.

Each Test Step Value can also be enhanced with dynamic values, expressions, or references to Tosca Buffers and Business Parameters.


Best Practices

  1. Reuse Modules: Avoid scanning the same screen repeatedly. Use reusable Modules to keep tests maintainable.
  2. Use Descriptive Naming: Clearly name your Test Steps and Test Cases to make them readable and understandable to team members.
  3. Modularize Test Cases: Break complex workflows into smaller, reusable test cases or modules.
  4. Parameterize: Use TestCase Templates and parameters for data-driven testing.


Conclusion

Test Steps and Test Step Values are at the heart of Tosca’s model-based testing approach. By mastering how to create, configure, and optimize them, testers can design robust, scalable, and maintainable test cases. Whether you're new to Tosca or enhancing an existing test suite, understanding these concepts will significantly improve your efficiency in test automation.

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...
