[INCA] Error-Code: 54

Issue

I am receiving an Error-code: 54 in my testcases.

What should I do to fix it?

Solution

In general, INCA error-code: 54 implies that INCA cannot deliver any measurement value.

You'll need to take a look at what is happening in INCA during testcase execution by pausing the test run, this can be done by inserting test steps that hold the execution ( e.g. message dialog test step) before the test step that you need to monitor. it's also possible to insert a breakpoint by right click on the test step under investigation and select Create/remove breakpoint, then run the test case in debug mode as shown below:
