Use this rule to control that the YAML documents do not contain a key. Key names can be defined as a regular expression.
With key-name = [tT]e.*t
the following code snippet would PASS:
Test1: value
tesT: {key1: 4, key2: 8}
the following code snippets would FAIL:
test: value
tesT: {Test: 4, key2: 8}
