rasengan 0.2.4

Is a command-line tool for automated testing of multiple kind of integrations tests for domains, with a simple and flexible YAML definition syntax.

Overview

rasengan, is a command-line tool for automated testing of multiple kind of integrations tests for domains, with a simple and flexible YAML definition syntax. The yaml file can contain multiple domains and we could check it in a diferent ways: - Check the DNS resolution - Check redirects, status code and expected URL in the redirect - Check http requests and the content text - Check http using different user-agents - Check SSL expiration date - Check SSL Qualys grade

The exit of the execution is an error if any of the checks fails. You can use a mrpe parameter to get MRPE simple and resume output.

Install & configure

rasengan is developed and tested with a python 3 version. We require >3.4 to install it.

To install rasengan we can use the PyPI package:

pip install rasengan

rasengan.yml

At this file you can specify the different for a domain:

Field	Description
dns	Check the DNS resolution, expect domain_type and result
ssl	Check the SSL status of the domain qualys test and expire date
http	Request the domain from http, expect status_code, redirect or text

Options in plugins

• dns:

  • domain_type: CNAME, A or another type of expected resolution in the domain.

  • expected: list of IPs or domains expected in the result.

• ssl:

  • grade: Qualys test expected grade.

  • days_to_expire: expiration days limit warning in the https certificate for the domain.

• http:

  • status_code: 200, 301, 302, 404, etc. Status code in the http request.

  • protocol: http or https, do the request over different http protocol. Default https.

  • redirect: expected redirect URL when you configure status code in 301 or 302.

  • path: The url path to check in the domain. Default is ‘/’.

  • text: check text in the result page when you expect 200 code.

  • user_agent: use a custom user_agent for the request or stored one from keys: mobile, desktop, google_desktop, google_mobile.

Usage

$ rasengan --help

  -l, --loglevel TEXT    Log level. Default INFO
  -w, --workers INTEGER  Number of threads to make the requests. Default 20.
  --mrpe / --no-mrpe     MRPE output (disable logging options). Default False, and if True disable loglevel.
  --help                 Show this message and exit.

- Integrate tavern to check APIs
- Check http with authentication
- Check http response time
- Manage and show exceptions ocurred in Future threads
