tests: support skipping to test method with STEP
Allow entering a test name on stack trace window with STEP=y option instead of a number. This allows to run a whole suite and skip all tests until a particular test is hit. Type: improvement Signed-off-by: Klement Sekera <ksekera@cisco.com> Change-Id: I23e45f8022b82545365b8921390e0e106e02b39c
