The configs field is an array of structures containing the same content as usual configs files.

For example:

configs = {
    # Set videotestsrc0 pattern value to `blue`
    "core, action=set-property, target-element-name=videotestsrc0, property-name=pattern, property-value=blue",
    "$(validateflow), pad=sink1:sink, caps-properties={ width, height };",
}

Note: Since this is GstStructure syntax, we need to have the structures in the array as strings/within quotes.

Warning: This field is validate only for .validatetest files, and not .scenario.
