[PATCH net-next 1/1] tools: tc-testing: Can pause just before post-suite

[Brenda J. Butler]

At debug level 5 or above, the test script will pause just before
the post_suite functions are called.  This allows the tester to
inspect the system before it is torn down.

[PATCH net-next 1/1] tools: tc-testing: Can refer to $TESTID in test spec

[Brenda J. Butler]

At debug level 5 or above, the test script will pause just before
the post_suite functions are called.  This allows the tester to
inspect the system before it is torn down.

When processing the commands in the test cases, substitute
the test id for $TESTID.  This helps to make more flexible
tests.  For example, the testid can be given as a command
line argument.

As an example, if we wish to save the test output to a file
named for the test case, we can write in the test case:

"cmdUnderTest": "some test command | tee -a $TESTID.out"

I've asked for changes in that patch, which means this needs updating
too.

Re: [PATCH net-next 1/1] tools: tc-testing: Can refer to $TESTID in test spec

[Brenda Butler]

The patches are independent and can be applied in any order.

I will change my process, to use send-email in separate invocations
for unrelated patches, so the patches are more obviously independent.
Sorry for the misleading submission.

Thanks for feedback.  I will resubmit the patches.

When someone adjusts the debug level, they expect that this is a control
over verbosity.

They don't expect it to potentially make the test hang at the TTY
waiting for user input.

Make a separate, appropriately named, knob for this.
