Common Tosca Errors and How to Fix Them

 🛠️ Common Tosca Errors and How to Fix Them

Tosca by Tricentis is a powerful test automation tool, but like any enterprise software, it comes with its own set of common errors. Whether you’re new to Tosca or a seasoned tester, here’s a list of frequently encountered issues — and how to resolve them.


✅ 1. “Object not found” / “Control not identified”

📌 Cause:

Application UI has changed (e.g., new XPath, ID)


Dynamic controls (e.g., changing IDs)


Incomplete or incorrect XScan mapping


🔧 Fix:

Re-scan the application with Tosca XScan


Use Dynamic IDs or buffered properties


Apply “Anchor” or “Automation Anchor” techniques


Use TBox Identify by Properties instead of fixed XPath


✅ 2. “Execution failed: Module not found”

📌 Cause:

Missing or deleted module


Module path has changed


🔧 Fix:

Right-click the test step → Choose Repair Links


Re-scan and re-link the correct module


Ensure no module reference is broken in the workspace


✅ 3. “Buffer not found”

📌 Cause:

Trying to use a buffer that was never set


Misspelled buffer name or improper case


🔧 Fix:

Check spelling and casing of buffer name (buffers are case-sensitive)


Make sure the buffer is defined before it's used


Use Set Buffer or Write to Buffer module before using the value


✅ 4. “No test cases found” in Execution List

📌 Cause:

TestCases are not linked to an ExecutionList


ExecutionList has no valid test cases in scope


🔧 Fix:

Drag TestCases manually into the ExecutionList


Check filters or dynamic folders that may be excluding TestCases


✅ 5. “Verification failed” for a field value

📌 Cause:

Incorrect verification value


Unexpected runtime value (timing issue or dynamic content)


🔧 Fix:

Add a WaitOn condition or synchronization (e.g., Wait for Control)


Use buffers or regular expressions for partial matching


Check actual value in Execution Log or Live View


✅ 6. “Cannot open workspace” or “Workspace is locked”

📌 Cause:

Another instance is already open


File lock wasn’t released correctly after a crash


🔧 Fix:

Close all Tosca sessions


Navigate to the workspace folder and delete .lock file manually


Restart Tosca Commander and reopen the workspace


✅ 7. “ActionMode is not valid”

📌 Cause:

Incorrect ActionMode value (e.g., typo in “Verify” or “Input”)


🔧 Fix:

Valid ActionModes: Input, Verify, Buffer, Constraint, WaitOn


Ensure correct spelling and casing


✅ 8. “Tosca not recognizing SAP / Web elements”

📌 Cause:

Missing browser or SAP engine support


Required plugins not installed or enabled


🔧 Fix:

Install and enable the appropriate Tosca engines (e.g., SAP, HTML)


For web apps:


Ensure Tosca Extensions are installed in Chrome/Edge


Launch browser via Tosca or AutomationHost


For SAP:


Enable scripting in SAP GUI


Set sapgui/user_scripting = TRUE in SAP


✅ 9. “TestStep has invalid configuration”

📌 Cause:

Required test data or module attribute missing


Invalid combination of ActionMode and value


🔧 Fix:

Validate that all required fields in the Module are filled


Use the Consistency Check feature (Ctrl + F6)


✅ 10. “Test Configuration Parameter (TCP) not found”

📌 Cause:

TCP not inherited or defined at the right level


🔧 Fix:

Define TCPs at Project, TestCase, or ExecutionList level


Check inheritance chain and override settings


Ensure correct usage via @{TCPName} in expressions


💡 General Troubleshooting Tips

🧪 Use ExecutionLog and Log Viewer for detailed error messages.


🔍 Use Search & Replace to find broken module or buffer references.


🧹 Run Consistency Checks on TestCases and ExecutionLists.


🔄 Restart Tosca Commander if things behave oddly — it helps in many cases.

Handling Frames and Iframes Using Playwright

Handling Frames and Iframes Using Playwright When automating modern web applications, you’ll often come across frames or iframes—HTML elements used to embed another HTML document within the current page. If you're using Playwright for browser automation, knowing how to handle frames properly is crucial for interacting with elements inside them. In this blog, we’ll walk through how to identify, access, and interact with frames and iframes using Playwright with code examples in JavaScript and Python. 🧾 What Are Frames and Iframes? <frame>: Rarely used now; part of the outdated <frameset> HTML structure. <iframe> (inline frame): Embeds another HTML page inside the current one. Common for third-party content like ads, maps, or payment gateways. 🎯 Why Frames Matter in Automation Elements inside an iframe are not part of the main DOM, so trying to interact with them directly will result in errors unless you switch the context to the frame. 🔍 Locating an Iframe in Pla...
