Rules

JSON rules consist of:

• A JSON path and either a literal value or a rule.

The possible rules are (x, y, z in the rules refer to parameters):

Rule	What it means
is a number	checks if every value that matches the JSON path is a number
> x	checks if every value that matches the JSON path is a number greater than x
>= x	checks if every value that matches the JSON path is a number greater than or equal to x
< x	checks if every value that matches the JSON path is a number less than x
<= x	checks if every value that matches the JSON path is a number less than or equal to x
is text	checks if every value that matches the JSON path is text of length 1 or longer
is text containing x	checks if every value that matches the JSON path is text that contains x
is text not containing x	checks if every value that matches the JSON path is text that does not contain x
is any of x y z	checks if every value that matches the JSON path is one of the values
is not x	checks if every value that matches the JSON path is not x
matches x	checks if every value that matches the JSON path matches the regular expression x
count = x	checks if the number of values that matches the JSON path is x
count > x	checks if the number of values that matches the JSON path is greater than x
count >= x	checks if the number of values that matches the JSON path is greater than or equal to x
count > x	checks if the number of values that matches the JSON path is greater than x
count >= x	checks if the number of values that matches the JSON path is greater than or equal to x
count < x	checks if the number of values that matches the JSON path is less than x
count <= x	checks if the number of values that matches the JSON path is less than or equal to x
each has x	checks if each of values that matches the JSON path is an object with a property called x
properties limited to x y z	checks if each of values that matches the JSON path is an object the properties of which cannot be anything other than x y or z

Header expectations consist of:

Header name followed by a colon and the expected value or a rule. There is one header rule, it is "must not be present". Examples:

"X-Powered-By":"Express"
"X-Powered-By": must not be present /* will fail if this header is sent */
