json = application/json
xml = application/xml
html = text/html
text = text/plain
urlencoded = application/x-www-form-urlencoded
form = application/x-www-form-urlencoded
form-data = application/x-www-form-urlencoded

Parameters:	value (str) – type alias or header value to match.
Returns:	`pook.Response` current instance.
Return type:	self

xml(xml)[source]¶

Defines the mock response XML body.

For not it only supports str as input type.

Parameters:	xml (str) – XML body data to use.
Returns:	`pook.Response` current instance.
Return type:	self

class pook.MatcherEngine[source]¶

Bases: list

HTTP request matcher engine used by pook.Mock to test if an intercepted outgoing HTTP request must be mocked out or not.

add(matcher)[source]¶

Adds a new matcher function to the current engine.

Parameters:	matcher (function) – matcher function to be added.

flush()[source]¶: Flushes the current matcher engine, removing all the registered matcher functions.

match(request)[source]¶

Match the given HTTP request instance against the registered matcher functions in the current engine.

Parameters:	request (pook.Request) – outgoing request to match.
Returns:	`True` if all matcher tests passes, otherwise `False`. Also returns an optional list of error exceptions.
Return type:	tuple(bool, list[Exception])

class pook.MockEngine(engine)[source]¶

Bases: object

MockEngine represents the low-level mocking engine abstraction layer between pook and the underlying mocking mechanism responsible of intercepting and trigger outgoing HTTP traffic within the Python runtime.

MockEngine implements the built-in pook mock engine based on HTTP interceptors strategy.

Developers can implement and plug in their own MockEngine in order to fit custom mocking logic needs.

You can see a custom MockEngine implementation here: http://bit.ly/2EymMro

Custom mock engines must implementent at least the following methods:

engine.__init__(self, engine)
engine.activate(self)
engine.disable(self)

Custom mock engines can optionally implement the following methods:

engine.add_interceptors(self, *interceptors)
engine.flush_interceptors(self)
engine.disable_interceptor(self, name) -> bool

Parameters:	engine (pook.Engine) – injected pook engine to be used.

engine¶: pook.Engine – stores pook engine to be used.

interceptors¶: list[pook.BaseInterceptor] – stores engine-level HTTP traffic interceptors.

activate()[source]¶

Activates the registered interceptors in the mocking engine.

This means any HTTP traffic captures by those interceptors will trigger the HTTP mock matching engine in order to determine if a given HTTP transaction should be mocked out or not.

add_interceptor(*interceptors)[source]¶

Adds one or multiple HTTP traffic interceptors to the current mocking engine.

Interceptors are typically HTTP client specific wrapper classes that implements the pook interceptor interface.

Parameters:	interceptors (pook.interceptors.BaseInterceptor) –

disable()[source]¶: Disables interceptors and stops intercepting any outgoing HTTP traffic.

flush_interceptors()[source]¶

Flushes registered interceptors in the current mocking engine.

This method is low-level. Only call it if you know what you are doing.

remove_interceptor(name)[source]¶

Removes a specific interceptor by name.

Parameters:	name (str) – interceptor name to disable.
Returns:	True if the interceptor was disabled, otherwise False.
Return type:	bool

Matchers API¶

Interceptors API¶

pook.interceptors.add(*interceptors)[source]¶

Registers a new HTTP client interceptor.

Parameters:	interceptors (interceptor*) – interceptor(s) to be added.

pook.interceptors.get(name)[source]¶

Returns an interceptor by class name.

Parameters:	name (str) – interceptor class name or alias.
Returns:	found interceptor instance, otherwise `None`.
Return type:	interceptor

class pook.interceptors.BaseInterceptor(engine)[source]¶

Bases: object

BaseInterceptor provides a base class for HTTP traffic interceptors implementations.

activate()[source]¶: Activates the traffic interceptor. This method must be implemented by any interceptor.

disable()[source]¶: Disables the traffic interceptor. This method must be implemented by any interceptor.

name¶: Exposes the interceptor class name.

class pook.interceptors.Urllib3Interceptor(engine)[source]¶

Bases: pook.interceptors.base.BaseInterceptor

Urllib3 HTTP traffic interceptor.

activate()[source]¶: Activates the traffic interceptor. This method must be implemented by any interceptor.

disable()[source]¶: Disables the traffic interceptor. This method must be implemented by any interceptor.

class pook.interceptors.HTTPClientInterceptor(engine)[source]¶

Bases: pook.interceptors.base.BaseInterceptor

urllib / http.client HTTP traffic interceptor.

activate()[source]¶: Activates the traffic interceptor. This method must be implemented by any interceptor.

disable()[source]¶: Disables the traffic interceptor. This method must be implemented by any interceptor.

class pook.interceptors.AIOHTTPInterceptor(engine)[source]¶

Bases: pook.interceptors.base.BaseInterceptor

aiohttp HTTP client traffic interceptor.

activate()[source]¶: Activates the traffic interceptor. This method must be implemented by any interceptor.

disable()[source]¶: Disables the traffic interceptor. This method must be implemented by any interceptor.
