Tosca Test Case Library: Building and Maintaining

Tricentis Tosca is a leading model-based test automation tool used by enterprises for end-to-end functional testing. At the heart of any effective Tosca automation project is the Test Case Library (TCL)—a centralized repository where test cases, test steps, and reusable modules are created, organized, and maintained.

In this blog, we’ll explore how to build and maintain a robust Test Case Library in Tosca, ensuring your testing efforts are scalable, maintainable, and aligned with business goals.


🚀 What is the Tosca Test Case Library?

The Test Case Library (TCL) in Tosca is a structured storage area where all test case designs, templates, and test step modules reside. It acts as a blueprint for generating actual test cases in the Execution List, and it’s tightly integrated with other components like Modules, Test Data, and Requirements.

A well-maintained TCL helps teams:

Avoid duplication

Reuse test steps efficiently

Manage large-scale projects

Adapt quickly to changes in the application under test


🏗️ Building Your Test Case Library

Here are the key steps to build a scalable Test Case Library in Tosca:

1. Define a Folder Structure

Use a clear and consistent folder hierarchy to organize test cases by:

Application area (e.g., Login, Checkout, Dashboard)

Functional module

Business process

Example structure:


pgsql


TestCaseDesign

├── Login

│   ├── Valid Login

│   └── Invalid Login

├── Orders

│   ├── Place Order

│   └── Cancel Order

This structure improves navigation and simplifies test case management.


2. Use Reusable Test Step Modules

Tosca promotes modular testing. Design reusable test steps (TSMs) for common actions like:

Launch application

Enter username/password

Click login

Log out

You can drag and drop these into different test cases, saving time and reducing maintenance effort.


3. Leverage Test Case Templates and Test Case Design (TCD)

Use Tosca TCD to create template-based test cases that separate logic from data. This enables data-driven testing where one template can generate multiple test instances using different datasets.

Benefits:

Easier maintenance

Better coverage

Dynamic test generation


4. Link with Requirements and Modules

Associate your test cases with requirements to ensure traceability and coverage. Also, link test steps to Modules (automated representations of UI elements) created using Tosca's Scan functionality.


🧹 Maintaining the Test Case Library

Once your TCL is up and running, follow these best practices to maintain it effectively:


✅ 1. Perform Regular Reviews

Schedule periodic reviews to:

Archive outdated test cases

Identify and remove redundancies

Validate folder structure


✅ 2. Update Affected Modules Proactively

If the application UI changes, use Tosca’s Impact Analysis to identify all test cases that depend on the changed modules and update them accordingly.


✅ 3. Use Naming Conventions

Maintain consistent naming conventions for test cases, modules, and folders (e.g., TC_Login_ValidCredentials, TSM_ClickLogin). This helps improve readability and searchability.


✅ 4. Use Version Control

Leverage Tosca's versioning features (or integrate with tools like Git) to track changes in test assets and roll back if needed.


✅ Conclusion

Building and maintaining a clean and modular Tosca Test Case Library is essential for scaling your test automation efforts. With reusable components, logical structures, and data-driven templates, teams can ensure their tests remain efficient, maintainable, and aligned with the application’s evolving requirements.

By investing in a strong TCL foundation, QA teams can maximize ROI from Tosca and deliver faster, more reliable releases.

How to Use Tosca's Test Configuration Parameters

Tosca by Tricentis is a powerful model-based test automation tool widely used in enterprise environments for end-to-end testing. One of its most useful features is Test Configuration Parameters (TCPs), which provide flexibility and control in managing test execution. TCPs enable testers to create reusable test cases by passing dynamic values without hardcoding them. This significantly enhances test maintenance, scalability, and efficiency. In this blog, we’ll explore what Test Configuration Parameters are, how to create and use them, and the best practices to follow when working with TCPs in Tosca. What Are Test Configuration Parameters? Test Configuration Parameters are custom-defined key-value pairs that can be associated with test cases, test case folders, or execution lists in Tosca. They help manage configuration data such as environment URLs, browser types, credentials, or any other variable data that may differ across test runs. By using TCPs, you can avoid duplicating test case...

Using Hibernate ORM for Fullstack Java Data Management

In the world of fullstack Java development, managing data efficiently and seamlessly across the application is critical. One of the most powerful tools in the Java ecosystem for handling database operations is Hibernate ORM (Object-Relational Mapping). Hibernate simplifies the interaction between Java applications and relational databases, reducing boilerplate code and improving maintainability. This blog explores how Hibernate ORM works, why it’s widely used, and how it fits into the data management strategy of a fullstack Java application. What is Hibernate ORM? Hibernate ORM is an open-source Java framework that provides a powerful and flexible mechanism for mapping Java objects to database tables. It abstracts the low-level JDBC code, allowing developers to work with high-level object-oriented concepts. Instead of writing raw SQL queries, Hibernate allows developers to define database interactions using simple Java classes (also known as POJOs) and annotations or XML configurations...

Creating a Test Execution Report with Charts in Playwright

Modern test automation isn't just about running tests—it's also about presenting clear, visual feedback on test results. When working with Playwright, one of the most powerful end-to-end testing tools for modern web apps, generating detailed execution reports can help your team track progress, identify issues quickly, and make data-driven decisions. A visual report with charts brings your testing efforts to life. In this blog, we’ll walk through how to create a test execution report with charts using Playwright’s built-in capabilities along with third-party tools for enhanced visualization. Why Visual Reports Matter Plain text logs and console outputs are hard to parse at scale. A good report should answer questions like: How many tests passed or failed? What’s the overall success rate? Which tests are flaky or slow? How have test results changed over time? Visualizing this data with charts—like pie charts, bar graphs, or timelines—helps QA teams and stakeholders better underst...
