Class Method Details
.parse(lcm_output, test_dsc_configuration) ⇒ Object
Parses the output from LCM and returns a list of Chef::Util::DSC::ResourceInfo objects that describe how the resources affected the system
Example for WhatIfParser:
parse <<-EOF
What if: [Machine]: LCM: [Start Set ]
What if: [Machine]: LCM: [Start Resource ] [[File]FileToNotBeThere]
What if: [Machine]: LCM: [Start Set ] [[File]FileToNotBeThere]
What if: [C:\ShouldNotExist.txt] removed
What if: [Machine]: LCM: [End Set ] [[File]FileToNotBeThere] in 0.1 seconds
What if: [Machine]: LCM: [End Resource ] [[File]FileToNotBeThere]
What if: [Machine]: LCM: [End Set ]
EOF
would return
[
Chef::Util::DSC::ResourceInfo.new(
'[[File]FileToNotBeThere]',
true,
[
'[[File]FileToNotBeThere]',
'[C:\Shouldnotexist.txt]',
'[[File]FileToNotBeThere] in 0.1 seconds'
]
)
]
Example for TestDSCParser:
parse <<-EOF
InDesiredState : False
ResourcesInDesiredState :
ResourcesNotInDesiredState: {[Environment]texteditor}
ReturnValue : 0
PSComputerName : .
EOF
would return
[
Chef::Util::DSC::ResourceInfo.new(
'{[Environment]texteditor}',
true,
[
