httptest (version 3.0.0)

expect_verb: Expectations for mocked HTTP requests

Description

The mock contexts in httptest can raise errors or messages when requests are made, and those (error) messages have three elements, separated by space: (1) the request method (e.g. "GET"); (2) the request URL; and (3) the request body, if present. These verb-expectation functions look for this message shape. expect_PUT, for instance, looks for a request message that starts with "PUT".

Usage

expect_GET(object, url = "", ...)
expect_POST(object, url = "", ...)
expect_PATCH(object, url = "", ...)
expect_PUT(object, url = "", ...)
expect_DELETE(object, url = "")
expect_no_request(object, ...)

Arguments

object

Code to execute that may cause an HTTP request

url

character: the URL you expect a request to be made to. Default is an empty string, meaning that you can just assert that a request is made with a certain method without asserting anything further.

...

character segments of a request payload you expect to be included in the request body, to be joined together by paste0

Value

A testthat 'expectation'.

Examples

# NOT RUN {
library(httr)
without_internet({
    expect_GET(GET("http://httpbin.org/get"),
        "http://httpbin.org/get")
    expect_PUT(PUT("http://httpbin.org/put", body='{"a":1}'),
        'http://httpbin.org/put',
        '{"a":1}')
    expect_PUT(PUT("http://httpbin.org/put", body='{"a":1}'))
    expect_no_request(rnorm(5))
})
