Final answer:
The value set on the executionlist takes precedence over the value set on the testcase level.
Step-by-step explanation:
When a test configuration parameter is set on the testcase level and the same one is set on an executionlist, the value set on the executionlist will be used for the testcase when the executionlist is run.
For example, let's say there is a test configuration parameter called 'timeout' and it is set to 5 seconds on the testcase level. However, on an executionlist, the same parameter is set to 10 seconds. When the executionlist is run, the 'timeout' value of 10 seconds will be used for the testcase.
In summary, the value set on the executionlist takes precedence over the value set on the testcase level.
