HC error message could be improved
Summary
When a tsp(test suite parameter) is not initialized, but it is used in the TTCN code as default value of a parameter of a function, executing test cases that use the function fails. The error message displayed could be made richer to easily spot which tsps are causing the issue. Part of the error message at the moment is: "Assignment of an unbound charstring value.". It does not say which tsp or which line or which function.
Steps and/or TTCN-3 code to reproduce
- Create a tsp and do not assign default value.
- Create a function that uses the tsp as a default value of one of its parameters.
- Use the function in a TC
- Execute the test case
I have attached a TTCN file and a cfg file for this.
What is the current bug behavior?
The TC execution fails with DTE before it starts during configuring the HC. The core error message is: Dynamic test case error: Assignment of an unbound charstring value.
What is the expected correct behavior?
It would be more helpful if the error message specified (if possible)
- The line number where the problem occurs
- The function where the problem occurs
- The tsp causing the problem
