delays

Demonstrates how to add latency to calls, based on host, and method type. import hoverpy’s main class: HoverPy

>>> from hoverpy import HoverPy

Import requests and random for http and testing

>>> import requests
>>> import random

Create our HoverPy object in capture mode

>>> with HoverPy(capture=True) as hp:

This function either generates a echo server url, or a md5 url it is seeded so that we get the exact same requests on capture as we do on simulate

>>>     def getServiceData():
>>>         for i in range(10):
>>>             random.seed(i)
>>>             print(
>>>                 requests.get(
>>>                     random.choice(
>>>                         [
>>>                             "http://echo.jsontest.com/i/%i" %
>>>                             i,
>>>                             "http://md5.jsontest.com/?text=%i" %
>>>                             i])).json())

Make the requests to the desired host dependencies

>>>     print("capturing responses from echo server\n")
>>>     getServiceData()

There are two ways to add delays. One is to call the delays method with the desired delay rules passed in as a json document

>>>     print(hp.delays({"data": [
>>>         {
>>>             "urlPattern": "md5.jsontest.com",
>>>             "delay": 1000
>>>         }
>>>     ]
>>>     }
>>>     ))

The other more pythonic way is to call addDelay(...)

>>>     print(hp.addDelay(urlPattern="echo.jsontest.com", delay=3000))

Now let’s switch over to simulate mode

>>>     print(hp.simulate())

Make the requests. This time HoverFly adds the simulated delays. these requests would normally be run asynchronously, and we could deal gracefully with the dependency taking too long to respond

>>>     print("\nreplaying delayed responses from echo server\n")
>>>     getServiceData()
