Tosca Mobile Automation: Tools and Techniques
With the growing reliance on mobile applications, ensuring high-quality mobile user experiences is more important than ever. To meet this demand, test automation tools have evolved to support both Android and iOS platforms. Tosca, a model-based testing tool by Tricentis, is widely known for its powerful capabilities in enterprise test automation—including support for mobile automation.
In this blog, we'll explore the key tools and techniques used in Tosca mobile automation, covering how it works, what technologies it integrates with, and best practices to ensure effective mobile test coverage.
What is Tosca Mobile Automation?
Tosca Mobile Automation enables testers to automate functional and regression tests for mobile apps without writing code. It leverages Tosca's model-based approach, allowing users to scan applications and create reusable test components called TestCases, Modules, and TestSteps.
Tosca supports mobile testing through integration with Appium, a popular open-source tool for automating native, hybrid, and mobile web apps.
Key Tools in Tosca Mobile Automation
1. Tosca Mobile+
Tosca Mobile+ is the enhanced mobile testing solution in Tosca. It offers:
Native support for iOS and Android
Integration with real devices and emulators
Connection to cloud-based device farms (e.g., Sauce Labs, BrowserStack)
2. Appium Integration
Appium acts as the bridge between Tosca and the mobile device. Tosca creates and executes test cases while Appium communicates directly with the device or emulator.
You must install:
Appium Server
Android SDK or Xcode (for iOS)
Required drivers for Android/iOS
3. Mobile Engine 3.0
This is the latest engine for mobile automation in Tosca, replacing older versions. It provides better performance, more stability, and full support for Appium-based test execution.
Techniques for Tosca Mobile Automation
1. Scanning the Mobile Application
Using Tosca Mobile+ and connected Appium server:
Connect a real device or emulator
Launch Tosca Commander
Use Tosca’s Scan functionality to capture UI elements of the mobile app
Automatically create Modules for each screen/view
2. Creating Reusable Test Cases
After scanning:
Drag and drop Modules into TestCases
Define TestSteps by assigning values and conditions
Use TestCase Templates for data-driven testing
3. Test Execution
Define execution lists in ExecutionLists
Run tests locally or remotely on real devices/emulators
View detailed execution logs and screenshots for each step
Best Practices for Mobile Automation in Tosca
Use Stable Locators:
Always prefer stable identifiers like accessibility id or resource-id over XPath to ensure test reliability.
Run on Real Devices and Emulators:
Test on both to ensure compatibility and catch device-specific issues.
Modularize Your Tests:
Create reusable Modules for each screen or component. This improves maintainability.
Implement Data-Driven Testing:
Use TestCase Templates and TestSheets for scalable and flexible test coverage.
Integrate with CI/CD Pipelines:
Use Tosca’s CLI to run mobile tests as part of continuous integration workflows.
Conclusion
Tosca’s model-based, no-code approach makes it an excellent choice for enterprises looking to automate mobile application testing efficiently. By combining Tosca with tools like Appium and leveraging Mobile Engine 3.0, QA teams can deliver robust, reusable, and scalable tests across devices and platforms. As mobile applications become more complex and critical, investing in structured automation using Tosca ensures quality, speed, and continuous delivery.
