@jeromecoutant Is there a reason why we want to remove the customized durations? Are you seeing unnecessary timeouts?

[jeromecoutant]

This duration looks to be the timeout value for serial init time before test start.
So it doesn't need any customization...

[bridadan]

@jeromecoutant I believe the duration value is also used to determine if a test should TIMEOUT or not. And this can vary depending on how long the test runs. If the test is a very short test, it is often set to a smaller value so the tester isn't waiting too long for it to finish. But for long tests, this can be customized to be a larger value. So it's basically just an optimization to reduce the amount of time you're waiting for a test result from a potentially failing test.

For this reason, I don't think we'd want to mess with the customized duration values inside test.py.

Hi

I didn’t see this… Test timeout value looks to be set in the main.cpp file with for ex:
MBED_HOSTTEST_TIMEOUT(10);

duration value is used while executing host_test.py
with -t parameter

@jeromecoutant Ah yes, that bit totally slipped my mind! Should probably be ok. I'll run mbed 2 testing

Failure is from a build issue on an unrelated target, LGTM
