edatool
The diagnostics tools include edatool. To test the basic functionality of the system, use the edatool.
The edatool executes a script of simple commands, similar to commands in the CLI. Usually, the diagnostics tools run these types of
tests. The success or failure of these tools is reported. At the end of the edatool run, reports the PASSED or FAILED results in a
standard format the test scripts can easily parse.
Tests
The edatool does not have a test command, but instead runs all the tests that are scripted.
