2 Documentation Robot keyword library (Resource) for runtime changes to config subsystem state using restconf calls.

11 ... The purpose of this library is to make runtime changes to ODL configuration
12 ... easier from Robot suite contributor point of view.
14 ... Different ODL parts have varying ways of configuration,
15 ... this library affects only the Config Subsystem way.
16 ... Config Subsystem has (apart Java APIs mostly available only from inside of ODL)
17 ... NETCONF server as its publicly available entry point.
18 ... Netconf-connector feature makes this netconf server available for RESTCONF calls.
19 ... Unfortunately, URIs and data payloads tend to be quite convoluted,
20 ... so using RequestsLibrary directly from test cases is unwieldy.
22 ... The main strength of this library are *_Template_Folder_Config_Via_Restconf keywords
23 ... User gives a path to directory where files with templates for URI fragment
24 ... and XML (or JSON) data are present, and a mapping with substitution to make;
25 ... the keywords will take it from there.
28 ... * netconf-connector feature installed on ODL.
29 ... * Setup_Config_Via_Restconf called from suite Setup
30 ... (or before any other call to a keyword from this library) at least once.
