Test execution from Rational Test RealTime shows zero coverage results

Technote (troubleshooting)


Problem(Abstract)

IBM Rational Test RealTime shows zero coverage results after a successful test execution.

Cause

This could be caused by buffer overflow.

Diagnosing the problem

Verify buffer size set from the value for the field RTRT_ BUFFER_SIZE in the Target Deployment Port (TDP).

Resolving the problem

Extend the value of the RTRT_ BUFFER_SIZE field to avoid the buffer overflow.


For example, if the value is set to 256 bytes, extend it to 512 or 1024 bytes.

Additionally "On the fly frequency dump" setting under Run time analysis > Advanced options can also be used to dump the data while in the middle of execution.
