http_voodoo_mongo ~ remote control your MongoDB over HTTP

@github: https://github.com/abhishekkr/http_voodoo_mongo

project name: http_voodoo_mongo

platform:     linux

requirement:  ruby

usage: it's a remote controller for your local/remote MongoDB instances working over an HTTP mocking service

What it consists of?

[] a rakefile 'Rakefile' allowing you to auto install and start 'http_voodoo_mongo' as a system service using "rake http_mongo:install" task.

[] a ruby script 'mongo_voodoo.rb' which mocks HTTP Server and allows you control MongoDB using HTTP Requests.

[] a system service script 'mongo_voodoo' which enables you to start||stop||status||restart the Ruby Script as a System Service

*currently I've just added "mongodump" task to it (with & without authorization detail), will slowly add more..... it's all opensource, even you can update if you want

======================================================

a REST API for Remote Controlling MongoDB Server over HTTP using the same 'authentication' as of MongoDB Server

[] need to access the service at HTTP_URL => http://[MongoDB_IP]:30303/

[] Optional GET Request Parameters [name] the username permitted access [pass] the password linked to username [port] the port at which MongoDB Server is running

 ::MongoDB Database Backup 

  http://[MongoDB_IP]:30303/[db_name]?action=dump&dir=[dir]&more_switch=[more_switch]&userniame=[username]&password=[password]&port=[port] 

[] GET Parameters [dir] the directory to take in backup using mongodump [more_switch] any options you wanna add to mongodump command

Make *nix automatic re-spawn a process/service if stopped

To make your *nix system automatic re-spawn a process/service if stopped ~

Write a shell script to check for presence of a service and start it if it is not running.
Then attach that shell-script to a cronjob running at frequent intervals.

Example Script to monitor Apache HTTPD web server and start it if is not started ~

#!/bin/sh
pids_=`ps ax | grep /usr/sbin/httpd | grep -v grep | wc -l `
if [ $pids_ -ne 0 ];
then
     echo "Apache is running"
else
     echo "Apache was stopped. Starting..."
     apache_start_=`/etc/init.d/httpd start`
     if [ $? -eq 0 ];
     then
         echo "Apache Started Successfully"
     fi
fi
#############################

 this simply checks for HTTPD process to be present and re-spawn the service in absence of even a single process thread.

There is a wonderful Ruby utility "bluepill" to achieve the same solution in a more advanced and comfortable manner. Cover it sooooon.....

derailed_cuke ~ now test any website using cucumber as an independent testing utility

GitHub Link: https://github.com/abhishekkr/abk-labs.cucumber

[] What is "Cucumber"?
+ http://cukes.info/

Cucumber lets software development teams define the behavior of any application in Business Readable DSL as plain text.
Hence serves as documentation, automated tests and development aid ~ All In One.

[] What is "derailed_cuke"?
+ Project Repo @GitHub


[] How To get "derailed_cuke"? + you could either clone the repo or download compressed project in following ways ~

Clone Repository:
#git clone git://github.com/abhishekkr/abk-labs.cucumber.git

Download As Zip: https://github.com/abhishekkr/abk-labs.cucumber/zipball/master

[] Pre-requisites for "derailed_cuke"?
+ Ruby, RubyGems & Bundler Gem installed


[] How to use "derailed_cuke"?
+ The downloaded project would have a directory "abk-labs.cucumber" with a directory "derailed_cuke" inside it.
~~~~~~~~~~
Step#1 Now all you need to do is open a console, change current working directory to "derailed_cukes".|
Step#2 Run "#bundle install" to install all required gems.
|
Step#3 If your ruby binary file is accessible by any name other than 'ruby' {i.e. say you are jruby and thus access it using 'jruby'}; then edit the file "Fcuke.rb" and replace the value of variable "RUBY_BIN" in line number 2 with the name you access your Ruby Binary.
|
Step#4 Now simple execute "Fcuke.rb" and by default it will check for two (already present for testing) features checking Google.com and Twitter.com
|
Step#5 To add custom web-application behavioral tests ~ user will need to write the custom Cucumber Features and respective Step Definitions {as in general scenario for using Cucumber}. For reference present feature and step definitions can be seen & used.
~~~~~~~~~~

[] Where to learn cucumber?
+ http://wiki.github.com/cucumber/cucumber/tutorials-and-related-blog-posts
In current release of "derailed_cuke", user need to know writing Cuke Features and Step Definitions.

………………………………………………………
[] Planned Goals for the Project involves
+ auto-generation of basic tests by analysis of application,
 then major task left would be to add uncovered custom tests
 and tweak the generated tests (if required).
