Test automation has evolved significantly from its early days in computing. This concept dates back to the 1970s when the first practical implementations of automated testing began to take shape. Fast forward to the 2000s, the emergence of various testing tools revolutionized the way teams handle software quality, offering greater speed, consistency, and efficiency.

If you’re currently exploring automation tools, it’s essential to understand the key differences between popular options like Leapwork vs Tosca. Additionally, there’s another tool worth mentioning – Testsigma.

What does Leapwork offers ?

Leapwork simplifies test automation by allowing users to create automation flows visually, making it accessible even for non-technical users. With the help of Smart Recorder, users can capture interactions with desktop and web applications to build automated processes without the need for code.  Additionally, the platform supports cross-browser testing, ensuring consistency across different platforms and browsers.

1. Visual Test Creation

  • Users can build automation flows without needing any coding skills.
  • Tasks like adding items to a shopping cart and checking out can be automated through simple screen recordings.
  • Even non-technical users can design tests by interacting with the application.

2. Data-Driven Testing

  • Tests can be run with different data sets, like checking pricing for members vs. non-members.
  • This allows thorough validation of different scenarios using the same test flow.

3. Reusable Components (Sub-Flows)

  • Sub-flows enable users to create reusable automation blocks, such as login/logout functions.
  • These can be reused in different test scenarios, saving time and reducing maintenance.

4. Cross-Browser and Cross-Platform Testing

  • Tests can be executed across multiple browsers like Chrome, Safari, etc., ensuring consistent results on different platforms.
  • This enhances test coverage across various devices and operating systems.

5. Smart Recorder

  • The Smart Recorder captures interactions with web and desktop applications, making it easy to automate tasks.
  • This streamlines the process of building automation flows. 

6. Automation Scheduling

  • Automation flows can be scheduled to run on various platforms.
  • This allows users to automate repetitive tasks and focus on other priorities while the system handles testing.
  •  Users can set up visual dashboards to track the status and outcomes of automation flows.

Where does Leapwork falls short? 


1. Debugging Complexity

  • Leapwork’s debugging capabilities are often challenging when dealing with complex flows. When bugs occur within nested sub-flows, it’s difficult to trace the exact point of failure. 
  • Users lack the ability to inspect context-specific data feeding into or out of problematic blocks, making troubleshooting time-consuming. Unlike traditional code-based environments where you can set breakpoints and inspect variables in real time, Leapwork’s visual flow needs the  users to manually trace each step, which slows down the debugging process.

2. Sensitivity to UI Changes

  • Leapwork’s automation flows are highly sensitive to changes in the user interface (UI). Even minor changes, like renaming a button from “Add to Cart” to “Add Item,” can cause all related test flows to fail. 
  • This reliance on visual recognition means every small UI update can trigger a need for manual flow adjustments, requiring extensive retesting and increasing the overall maintenance effort.

3. Image Recognition Issues

  • Leapwork’s image recognition struggles with certain tasks, particularly electronic signature recognition, which is reported to be slow and prone to timeouts. This limitation can lead to delays and inefficiencies when running automated tests that involve images or signatures.

What does tosca offers ?

Tricentis Tosca is a no-code automation tool that makes testing faster and easier across digital applications. It removes common bottlenecks and reduces risks in software releases.

1.Comprehensive Object Repository

  • Tosca’s object repository stores UI elements, ensuring reusability and consistency across tests. For example, you can define a “Login Button” once and reuse it in different test cases.
  • Tosca’s Comprehensive Object Repository acts as a central hub for managing all UI elements in your test cases. For instance, while testing an online banking app, you can store crucial UI components like the “Login Button” here. 
  • This means you only need to define it once—if its design changes, a single update in the repository ensures all tests reflect the new design. This significantly cuts down on maintenance time and guarantees consistency across your testing efforts.

2. Model-Based Testing

  • With Tosca’s model-based testing, Tests are created visually using flowcharts or JSON, making it accessible to non-technical users. 
  • Imagine testing an online shopping platform; you can effortlessly map out the process of adding items to the cart and checking out—all without writing a line of code. This visual approach not only simplifies the testing process but also makes it easier for team members with varying technical backgrounds to contribute.

3. Integrated Reporting

  • Tosca provides built-in reporting tools that generate clear, detailed feedback after tests. This allows teams to quickly identify and fix issues, improving the software quality. 
  • For example, after running tests on the shopping platform, you’ll receive clear and concise reports that indicate which tests succeeded and which didn’t. This immediate feedback enables teams to swiftly pinpoint and rectify issues, enhancing the overall quality of the application and boosting confidence in the release process.

4. Tosca Copilot

  • Tosca Copilot is an AI-powered assistant that boosts productivity by helping users manage and optimize test assets. It makes onboarding faster and reduces redundant efforts.

5. Service Virtualization

  • Tosca simulates system responses, allowing tests even when systems are not accessible or haven’t been built yet.

Pitfall of tosca:


1. Steep Learning Curve

  • Tosca is a powerful tool, but it’s not the easiest to learn. Just like a programming language, there are many ways to achieve the same goal, which can be overwhelming for new users. Without regular practice, it’s easy to forget how to perform tasks, making it necessary to stay active in the tool to retain knowledge.

2. License-Heavy

  • Tosca requires multiple licenses to access its various features, and a single license often isn’t enough to solve all your needs. You have to activate each feature in the settings, which can be time-consuming and adds an extra step before you can start working.

3. Performance Limitations

  • Tosca’s performance can slow down when handling applications with many elements. Before running tests, Tosca scans and stores each UI component, which can take extra time, especially for complex applications like retail websites with many product listings. This leads to longer execution times, impacting efficiency in larger projects.

These limitations show that while Tosca is feature-rich, it requires a significant investment in time, training, and licensing to use effectively.
