Wait for some HTTP response

Written in order to make functional tests less complicated.

Retries a HTTP request until it responds as expected or reaches the max attempt number.

Lets say we have an endpoint http://localhost:8080/health that give us a json, e.g., { "status": "UP" }. This script keep checking that endpoint until it receives the UP status or it reaches the max number of attempts.

Module

You can use a function from the module to wait for status responses.

import waitresponse
from waitresponse import waitresponse

# Make 2 attempts to get status=UP, trying every 1 seconds. 
respCode = waitresponse('http://localhost:8080/health', 2, 1, 'UP')
print(respCode) # 0 if success or else, 1

Script

python waitresponse.py url [OPTIONS]

url is the required endpoint, e.g., http://localhost:8080/health.

Options

• --max-attempts default=20 The max number of attempts.
• --sleep defaul=1 Sleep time, in seconds, between checks.
• --status default=UP The status to wait for. E.g., GREEN or YELLOW.
