Source: R/stub_body_diff.R
stub_body_diff.Rd

Requires the Suggested package diffobj

Usage

stub_body_diff(stub = last_stub(), request = last_request())

Arguments

stub

object of class StubbedRequest. required. default is to call last_stub(), which gets the last stub created

request

object of class RequestSignature. required. default is to call last_request(), which gets the last stub created

Value

object of class Diff from the diffobj package

Details

Returns error message if either stub or request are NULL. Even though you may not intentionally pass in a NULL, the return values of last_stub() and last_request() when there's nothing found is NULL.

Under the hood the Suggested package diffobj is used to do the comparison.

webmockr_configure() to toggle webmockr showing request body diffs when there's not a match. stub_body_diff() is offered as a manual way to compare requests and stubs - whereas turning on with webmockr_configure() will do the diff for you.
