Examples

Stubbing

Stubbed request based on uri only and with the default response

stub_request(:any, "www.example.com")

Net::HTTP.get("www.example.com", "/")    # ===> Success

Stubbing requests based on method, uri, body and headers

stub_request(:post, "www.example.com").
  with(body: "abc", headers: { 'Content-Length' => 3 })

uri = URI.parse("http://www.example.com/")
req = Net::HTTP::Post.new(uri.path)
req['Content-Length'] = 3

res = Net::HTTP.start(uri.host, uri.port) do |http|
  http.request(req, "abc")
end    # ===> Success

Matching request body and headers against regular expressions

stub_request(:post, "www.example.com").
  with(body: /world$/, headers: {"Content-Type" => /image\/.+/}).
  to_return(body: "abc")

uri = URI.parse('http://www.example.com/')
req = Net::HTTP::Post.new(uri.path)
req['Content-Type'] = 'image/png'

res = Net::HTTP.start(uri.host, uri.port) do |http|
  http.request(req, 'hello world')
end    # ===> Success

Matching request body against a hash. Body can be URL-Encoded, JSON or XML.

stub_request(:post, "www.example.com").
  with(body: {data: {a: '1', b: 'five'}})

RestClient.post('www.example.com', "data[a]=1&data[b]=five",
  content_type: 'application/x-www-form-urlencoded')    # ===> Success

RestClient.post('www.example.com', '{"data":{"a":"1","b":"five"}}',
  content_type: 'application/json')    # ===> Success

RestClient.post('www.example.com', '<data a="1" b="five" />',
  content_type: 'application/xml')    # ===> Success

Matching request body against partial hash.

stub_request(:post, "www.example.com").
  with(body: hash_including({data: {a: '1', b: 'five'}}))

RestClient.post('www.example.com', "data[a]=1&data[b]=five&x=1",
:content_type => 'application/x-www-form-urlencoded')    # ===> Success

Matching custom request headers

stub_request(:any, "www.example.com").
  with(headers:{ 'Header-Name' => 'Header-Value' })

uri = URI.parse('http://www.example.com/')
req = Net::HTTP::Post.new(uri.path)
req['Header-Name'] = 'Header-Value'

res = Net::HTTP.start(uri.host, uri.port) do |http|
  http.request(req, 'abc')
end    # ===> Success

Matching multiple headers with the same name

stub_request(:get, 'www.example.com').
  with(headers: {'Accept' => ['image/jpeg', 'image/png'] })

req = Net::HTTP::Get.new("/")
req['Accept'] = ['image/png']
req.add_field('Accept', 'image/jpeg')
Net::HTTP.start("www.example.com") {|http| http.request(req) }    # ===> Success

Matching requests against provided block

stub_request(:post, "www.example.com").with { |request| request.body == "abc" }
RestClient.post('www.example.com', 'abc')    # ===> Success

Request with basic authentication header

stub_request(:get, "www.example.com").with(basic_auth: ['user', 'pass'])
# or
# stub_request(:get, "www.example.com").
#   with(headers: {'Authorization' => "Basic #{ Base64.strict_encode64('user:pass').chomp}"})

Net::HTTP.start('www.example.com') do |http|
  req = Net::HTTP::Get.new('/')
  req.basic_auth 'user', 'pass'
  http.request(req)
end    # ===> Success

Important! Since version 2.0.0, WebMock does not match credentials provided in Authorization header and credentials provided in the userinfo of a url. I.e. `stub_request(:get, "user:pass@www.example.com")` does not match a request with credentials provided in the Authorization header.

Request with basic authentication in the url

stub_request(:get, "user:pass@www.example.com")

RestClient.get('user:pass@www.example.com')    # ===> Success

Matching uris using regular expressions

stub_request(:any, /example/)

Net::HTTP.get('www.example.com', '/')    # ===> Success

Matching uris using lambda

stub_request(:any, ->(uri) { true })

Matching uris using RFC 6570 - Basic Example

uri_template = Addressable::Template.new "www.example.com/{id}/"
stub_request(:any, uri_template)

Net::HTTP.get('www.example.com', '/webmock/')    # ===> Success

Matching uris using RFC 6570 - Advanced Example

uri_template =
  Addressable::Template.new "www.example.com/thing/{id}.json{?x,y,z}{&other*}"
stub_request(:any, uri_template)

Net::HTTP.get('www.example.com',

stub_request(:get, "www.example.com").
  with(query: hash_including({"a" => ["b", "c"]}))

RestClient.get("http://www.example.com/?a[]=b&a[]=c&x=1")    # ===> Success

Matching partial query params using hash_excluding

stub_request(:get, "www.example.com").
  with(query: hash_excluding({"a" => "b"}))

RestClient.get("http://www.example.com/?a=b")    # ===> Failure
RestClient.get("http://www.example.com/?a=c")    # ===> Success

Stubbing with custom response

stub_request(:any, "www.example.com").
  to_return(body: "abc", status: 200,
    headers: { 'Content-Length' => 3 })

File.open('/tmp/response_body.txt', 'w') { |f| f.puts 'abc' }

stub_request(:any, "www.example.com").
  to_return(body: File.new('/tmp/response_body.txt'), status: 200)

Net::HTTP.get('www.example.com', '/')    # ===> "abc\n"

Response with JSON body

stub_request(:any, "www.example.com").
  to_return_json(body: {foo: "bar"})

Net::HTTP.get('www.example.com', '/') # ===> "{\"foo\": \"bar\"}"

Response with custom status message

stub_request(:any, "www.example.com").
  to_return(status: [500, "Internal Server Error"])

req = Net::HTTP::Get.new("/")
Net::HTTP.start("www.example.com") { |http| http.request(req) }.
  message    # ===> "Internal Server Error"

Replaying raw responses recorded with `curl -is`

curl -is www.example.com > /tmp/example_curl_-is_output.txt

raw_response_file = File.new("/tmp/example_curl_-is_output.txt")

from file

stub_request(:get, "www.example.com").to_return(raw_response_file)

or string

stub_request(:get, "www.example.com").to_return(raw_response_file.read)

Responses dynamically evaluated from block

stub_request(:any, 'www.example.net').
  to_return { |request| {body: request.body} }

RestClient.post('www.example.net', 'abc')    # ===> "abc\n"

Responses dynamically evaluated from lambda

stub_request(:any, 'www.example.net').
  to_return(lambda { |request| {body: request.body} })

RestClient.post('www.example.net', 'abc')    # ===> "abc\n"

Dynamically evaluated raw responses recorded with `curl -is`

curl -is www.example.com > /tmp/www.example.com.txt

stub_request(:get, "www.example.com").
  to_return(lambda { |request| File.new("/tmp/#{request.uri.host.to_s}.txt") })

Responses with dynamically evaluated parts

stub_request(:any, 'www.example.net').
  to_return(body: lambda { |request| request.body })

RestClient.post('www.example.net', 'abc')    # ===> "abc\n"

Rack responses

class MyRackApp
  def self.call(env)
    [200, {}, ["Hello"]]
  end
end

stub_request(:get, "www.example.com").to_rack(MyRackApp)

RestClient.post('www.example.com')    # ===> "Hello"

Raising errors

Exception declared by class

stub_request(:any, 'www.example.net').to_raise(StandardError)

RestClient.post('www.example.net', 'abc')    # ===> StandardError

or by exception instance

stub_request(:any, 'www.example.net').to_raise(StandardError.new("some error"))

or by string

stub_request(:any, 'www.example.net').to_raise("some error")

Raising timeout errors

stub_request(:any, 'www.example.net').to_timeout

RestClient.post('www.example.net', 'abc')    # ===> RestClient::RequestTimeout

Multiple responses for repeated requests

stub_request(:get, "www.example.com").
  to_return({body: "abc"}, {body: "def"})
Net::HTTP.get('www.example.com', '/')    # ===> "abc\n"
Net::HTTP.get('www.example.com', '/')    # ===> "def\n"

#after all responses are used the last response will be returned infinitely

Net::HTTP.get('www.example.com', '/')    # ===> "def\n"

Multiple responses using chained `to_return()`, `to_raise()` or `to_timeout` declarations

stub_request(:get, "www.example.com").
  to_return({body: "abc"}).then.  #then() is just a syntactic sugar
  to_return({body: "def"}).then.
  to_raise(MyException)

Net::HTTP.get('www.example.com', '/')    # ===> "abc\n"
Net::HTTP.get('www.example.com', '/')    # ===> "def\n"
Net::HTTP.get('www.example.com', '/')    # ===> MyException raised

Specifying number of times given response should be returned

stub_request(:get, "www.example.com").
  to_return({body: "abc"}).times(2).then.
  to_return({body: "def"})

Net::HTTP.get('www.example.com', '/')    # ===> "abc\n"
Net::HTTP.get('www.example.com', '/')    # ===> "abc\n"
Net::HTTP.get('www.example.com', '/')    # ===> "def\n"

Removing unused stubs

stub_get = stub_request(:get, "www.example.com")
remove_request_stub(stub_get)

Real requests to network can be allowed or disabled

WebMock.allow_net_connect!

stub_request(:any, "www.example.com").to_return(body: "abc")

Net::HTTP.get('www.example.com', '/')    # ===> "abc"

Net::HTTP.get('www.something.com', '/')    # ===> /.+Something.+/

WebMock.disable_net_connect!

Net::HTTP.get('www.something.com', '/')    # ===> Failure

External requests can be disabled while allowing localhost

WebMock.disable_net_connect!(allow_localhost: true)

Net::HTTP.get('www.something.com', '/')    # ===> Failure

Net::HTTP.get('localhost:9887', '/')    # ===> Allowed. Perhaps to Selenium?

External requests can be disabled while allowing specific requests

Allowed requests can be specified in a number of ways.

With a String specifying a host name:

WebMock.disable_net_connect!(allow: 'www.example.org')

RestClient.get('www.something.com', '/')    # ===> Failure
RestClient.get('www.example.org', '/')      # ===> Allowed
RestClient.get('www.example.org:8080', '/') # ===> Allowed

With a String specifying a host name and a port:

WebMock.disable_net_connect!(allow: 'www.example.org:8080')

RestClient.get('www.something.com', '/')    # ===> Failure
RestClient.get('www.example.org', '/')      # ===> Failure
RestClient.get('www.example.org:8080', '/') # ===> Allowed

With a Regexp matching the URI:

WebMock.disable_net_connect!(allow: %r{ample\.org/foo})

RestClient.get('www.example.org', '/foo/bar') # ===> Allowed
RestClient.get('sample.org', '/foo')          # ===> Allowed
RestClient.get('sample.org', '/bar')          # ===> Failure

With an object that responds to #call, receiving a URI object and returning a boolean:

denylist = ['google.com', 'facebook.com', 'apple.com']
allowed_sites = lambda{|uri|
  denylist.none?{|site| uri.host.include?(site) }
}
WebMock.disable_net_connect!(allow: allowed_sites)

RestClient.get('www.example.org', '/')  # ===> Allowed
RestClient.get('www.facebook.com', '/') # ===> Failure
RestClient.get('apple.com', '/')        # ===> Failure

With an Array of any of the above:

WebMock.disable_net_connect!(allow: [
  lambda{|uri| uri.host.length % 2 == 0 },
  /ample.org/,
  'bbc.co.uk',
])

RestClient.get('www.example.org', '/') # ===> Allowed
RestClient.get('bbc.co.uk', '/')       # ===> Allowed
RestClient.get('bbc.com', '/')         # ===> Allowed
RestClient.get('www.bbc.com', '/')     # ===> Failure

Connecting on Net::HTTP.start

HTTP protocol has 3 steps: connect, request and response (or 4 with close). Most Ruby HTTP client libraries treat connect as a part of request step, with the exception of Net::HTTP which allows opening connection to the server separately to the request, by using Net::HTTP.start.

WebMock API was also designed with connect being part of request step, and it only allows stubbing requests, not connections. When Net::HTTP.start is called, WebMock doesn't know yet whether a request is stubbed or not. WebMock by default delays a connection until the request is invoked, so when there is no request, Net::HTTP.start doesn't do anything. This means that WebMock breaks the Net::HTTP behaviour by default!

To workaround this issue, WebMock offers :net_http_connect_on_start option, which can be passed to WebMock.allow_net_connect! and WebMock.disable_net_connect! methods, i.e.

WebMock.allow_net_connect!(net_http_connect_on_start: true)

This forces WebMock Net::HTTP adapter to always connect on Net::HTTP.start. At the time of connection being made there is no information about the request or URL yet, therefore WebMock is not able to decide whether to stub a request or not and all connections are allowed. To enable connections only to a specific domain (e.g. your test server) use:

WebMock.allow_net_connect!(net_http_connect_on_start: "www.example.com")

Setting Expectations

Setting expectations in Test::Unit

require 'webmock/test_unit'

stub_request(:any, "www.example.com")

uri = URI.parse('http://www.example.com/')
req = Net::HTTP::Post.new(uri.path)
req['Content-Length'] = 3

res = Net::HTTP.start(uri.host, uri.port) do |http|
  http.request(req, 'abc')
end

assert_requested :post, "http://www.example.com",
  headers: {'Content-Length' => 3}, body: "abc",
  times: 1    # ===> Success

assert_not_requested :get, "http://www.something.com"    # ===> Success

assert_requested(:post, "http://www.example.com",
  times: 1) { |req| req.body == "abc" }

Expecting real (not stubbed) requests

WebMock.allow_net_connect!

Net::HTTP.get('www.example.com', '/')    # ===> Success

assert_requested :get, "http://www.example.com"    # ===> Success

Setting expectations in Test::Unit on the stub

stub_get = stub_request(:get, "www.example.com")
stub_post = stub_request(:post, "www.example.com")

Net::HTTP.get('www.example.com', '/')

assert_requested(stub_get)
assert_not_requested(stub_post)

Setting expectations in RSpec on `WebMock` module

This style is borrowed from fakeweb-matcher

require 'webmock/rspec'

expect(WebMock).to have_requested(:get, "www.example.com").
  with(body: "abc", headers: {'Content-Length' => 3}).twice

expect(WebMock).not_to have_requested(:get, "www.something.com")

expect(WebMock).to have_requested(:post, "www.example.com").
  with { |req| req.body == "abc" }
# Note that the block with `do ... end` instead of curly brackets won't work!
# Why? See this comment https://github.com/bblimke/webmock/issues/174#issuecomment-34908908

expect(WebMock).to have_requested(:get, "www.example.com").
  with(query: {"a" => ["b", "c"]})

expect(WebMock).to have_requested(:get, "www.example.com").
  with(query: hash_including({"a" => ["b", "c"]}))

expect(WebMock).to have_requested(:get, "www.example.com").
  with(body: {"a" => ["b", "c"]},
    headers: {'Content-Type' => 'application/json'})

Setting expectations in RSpec with `a_request`

expect(a_request(:post, "www.example.com").
  with(body: "abc", headers: {'Content-Length' => 3})).
  to have_been_made.once

expect(a_request(:post, "www.something.com")).to have_been_made.times(3)

expect(a_request(:post, "www.something.com")).to have_been_made.at_least_once

expect(a_request(:post, "www.something.com")).
  to have_been_made.at_least_times(3)

expect(a_request(:post, "www.something.com")).to have_been_made.at_most_twice

expect(a_request(:post, "www.something.com")).to have_been_made.at_most_times(3)

expect(a_request(:any, "www.example.com")).not_to have_been_made

expect(a_request(:post, "www.example.com").with { |req| req.body == "abc" }).
  to have_been_made

expect(a_request(:get, "www.example.com").with(query: {"a" => ["b", "c"]})).
  to have_been_made

expect(a_request(:get, "www.example.com").
  with(query: hash_including({"a" => ["b", "c"]}))).to have_been_made

expect(a_request(:post, "www.example.com").
  with(body: {"a" => ["b", "c"]},
    headers: {'Content-Type' => 'application/json'})).to have_been_made

Setting expectations in RSpec on the stub

stub = stub_request(:get, "www.example.com")
# ... make requests ...
expect(stub).to have_been_requested

Clearing stubs and request history

If you want to reset all current stubs and history of requests use WebMock.reset!

stub_request(:any, "www.example.com")

Net::HTTP.get('www.example.com', '/')    # ===> Success

WebMock.reset!

Net::HTTP.get('www.example.com', '/')    # ===> Failure

assert_not_requested :get, "www.example.com"    # ===> Success

Clearing request counters

If you want to reset only the counters of the executed requests use WebMock.reset_executed_requests!

stub  = stub_request(:get, "www.example.com")
stub2 = stub_request(:get, "www.example2.com")

Net::HTTP.get('www.example.com', '/')
Net::HTTP.get('www.example.com', '/')

Net::HTTP.get('www.example2.com', '/')

expect(stub).to have_been_requested.times(2)
expect(stub2).to have_been_requested.times(1)

WebMock.reset_executed_requests!

expect(stub).not_to have_been_requested
expect(stub2).not_to have_been_requested

Disabling and enabling WebMock or only some http client adapters

# Disable WebMock (all adapters)
WebMock.disable!

# Disable WebMock for all libs except Net::HTTP
WebMock.disable!(except: [:net_http])

# Enable WebMock (all adapters)
WebMock.enable!

# Enable WebMock for all libs except Patron
WebMock.enable!(except: [:patron])

Matching requests

An executed request matches stubbed request if it passes following criteria:

When request URI matches stubbed request URI string, Regexp pattern or RFC 6570 URI Template
And request method is the same as stubbed request method or stubbed request method is :any
And request body is the same as stubbed request body or stubbed request body is not specified
And request headers match stubbed request headers, or stubbed request headers match a subset of request headers, or stubbed request headers are not specified
And request matches provided block or block is not provided

Precedence of stubs

Always the last declared stub matching the request will be applied i.e:

stub_request(:get, "www.example.com").to_return(body: "abc")
stub_request(:get, "www.example.com").to_return(body: "def")

Net::HTTP.get('www.example.com', '/')    # ====> "def"

Matching URIs

WebMock will match all different representations of the same URI.

I.e all the following representations of the URI are equal:

"www.example.com"
"www.example.com/"
"www.example.com:80"
"www.example.com:80/"
"http://www.example.com"
"http://www.example.com/"
"http://www.example.com:80"
"http://www.example.com:80/"

The following URIs with userinfo are also equal for WebMock

"a b:pass@www.example.com"
"a b:pass@www.example.com/"
"a b:pass@www.example.com:80"
"a b:pass@www.example.com:80/"
"http://a b:pass@www.example.com"
"http://a b:pass@www.example.com/"
"http://a b:pass@www.example.com:80"
"http://a b:pass@www.example.com:80/"
"a%20b:pass@www.example.com"
"a%20b:pass@www.example.com/"
"a%20b:pass@www.example.com:80"
"a%20b:pass@www.example.com:80/"
"http://a%20b:pass@www.example.com"
"http://a%20b:pass@www.example.com/"
"http://a%20b:pass@www.example.com:80"
"http://a%20b:pass@www.example.com:80/"

or these

"www.example.com/my path/?a=my param&b=c"
"www.example.com/my%20path/?a=my%20param&b=c"
"www.example.com:80/my path/?a=my param&b=c"
"www.example.com:80/my%20path/?a=my%20param&b=c"
"http://www.example.com/my path/?a=my param&b=c"
"http://www.example.com/my%20path/?a=my%20param&b=c"
"http://www.example.com:80/my path/?a=my param&b=c"
"http://www.example.com:80/my%20path/?a=my%20param&b=c"

If you provide Regexp to match URI, WebMock will try to match it against every valid form of the same url.

I.e /my path/ will match www.example.com/my%20path because it is equivalent of www.example.com/my path

Matching with URI Templates

If you use Addressable::Template for matching, then WebMock will defer the matching rules to Addressable, which complies with RFC 6570.

If you use any of the WebMock methods for matching query params, then Addressable will be used to match the base URI and WebMock will match the query params. If you do not, then WebMock will let Addressable match the full URI.

Matching headers

WebMock will match request headers against stubbed request headers in the following situations:

Stubbed request has headers specified and request headers are the same as stubbed headers
i.e stubbed headers: { 'Header1' => 'Value1', 'Header2' => 'Value2' }, requested: { 'Header1' => 'Value1', 'Header2' => 'Value2' }
Stubbed request has headers specified and stubbed request headers are a subset of request headers
i.e stubbed headers: { 'Header1' => 'Value1' }, requested: { 'Header1' => 'Value1', 'Header2' => 'Value2' }
Stubbed request has no headers
i.e stubbed headers: nil, requested: { 'Header1' => 'Value1', 'Header2' => 'Value2' }

WebMock normalises headers and treats all forms of same headers as equal: i.e the following two sets of headers are equal:

{ "Header1" => "value1", content_length: 123, X_CuStOm_hEAder: :value }

{ header1: "value1", "Content-Length" => 123, "x-cuSTOM-HeAder" => "value" }

Recording real requests and responses and replaying them later

To record your application's real HTTP interactions and replay them later in tests you can use VCR with WebMock.

Request callbacks

WebMock can invoke callbacks stubbed or real requests:

WebMock.after_request do |request_signature, response|
  puts "Request #{request_signature} was made and #{response} was returned"
end

invoke callbacks for real requests only and except requests made with Patron

WebMock.after_request(except: [:patron],
                      real_requests_only: true) do |req_signature, response|
  puts "Request #{req_signature} was made and #{response} was returned"
end

If you have any suggestions on how to improve WebMock please send an email to the mailing list groups.google.com/group/webmock-users

I'm particularly interested in how the DSL could be improved.

Development

In order to work on Webmock you first need to fork and clone the repo. Please do any work on a dedicated branch and rebase against master before sending a pull request.

Background

Thank you Fakeweb! This library was inspired by FakeWeb. I imported some solutions from that project to WebMock. I also copied some code i.e Net:HTTP adapter. Fakeweb architecture unfortunately didn't allow me to extend it easily with the features I needed. I also preferred some things to work differently i.e request stub precedence.
