Instance Method Details

#affected_input_name=(name) ⇒ Object

Overrides Capabilities::Mutable#affected_input_name= to allow for non-string data of variable depth.

Parameters:

  • name (Array<String>, String)

    Sets the name of the fuzzed input.

    If the name is an Array, it will be treated as a path to the location of the input.

def affected_input_name=( name )
    if name.is_a?( Array ) && name.size == 1
        name = name.first
    end

    @affected_input_name = name
end

#each_mutation(payload, options = {}) {|mutation| ... } ⇒ Object

Note:

Vector names in Capabilities::Mutable#immutables will be excluded.

Overrides Capabilities::Mutable#each_mutation to allow for auditing of non-string data of variable depth.

Parameters:

Yields:

  • (mutation)

    Each generated mutation.
