The trace-cmd runtime test has a typo and fails with output:
Traceback (most recent call last):
File "/build/buildroot/support/testing/tests/package/test_trace_cmd.py", line 53, in test_run
self.assertEquals(exit_code, 0)
^^^^^^^^^^^^^^^^^
AttributeError: 'TestTraceCmd' object has no attribute 'assertEquals'. Did you mean: 'assertEqual'?
The issue can be reproduced with the command:
support/testing/run-tests \
-d dl -o output_test \
tests.package.test_trace_cmd
This commit fixes the issue by removing the extra 's'.
