Sneak Preview of STB Suite 8.7

Custom Log entries for DMM

The upcoming next release of the STB has, as usual, a number of new features and improvements. One of these is Custom Log entries for DMM.

A customizable field for each test step

Each test step can have a user-entered text field which is defined while defining the test step, using the Advanced Options page –

Each test step can have it’s own entry, and of course these entries are stored in any sequence file that you save.

An “Overall” field for the entire test

When a test is run you are given the opportunity to enter an operator ID and also an overall test description –

The final result

Here is an edited example log file generated by the “DoD5220DiskPurge” test sequence
