Parameterised Scheduler Plugin

“VJ, I want you to run the automation job on all our three environments on a nightly basis. So that we can compare the results & find out any discrepancies across environments.”

My team lead said this to me one day out of the blue.A small background on this – we have automation scripts used to test Rest APis on our cloud. This normally runs on a single environment every night, mainly pre-prod.Now the requirement was to run the same set of scripts on all environments i.e staging/dev, pre-prod & prod.

This was a new and exciting task for me and I got on with it right away!

Till now, I only knew how to schedule a job periodically as I had earlier written a blog post regarding it. But I did not know how to schedule the same job, multiple times with different parameters.

I found exactly what I needed in the Parameterised Scheduler Plugin!!

So once you install this plugin,restart the jenkins application for it to take effect. Very important. I tried scheduling it without restart and the plugin did not work.

Here’s how you can schedule the same job multiple times throughout the day with different parameters:-

Build_periodically_with_parameters

The % symbol separates the cron notation from the parameters(if any) that you want to give for your run. ‘env’ is my parameter which my scripts pick up.

Another example of scheduling the same job with multiple parameters :-

Scheduling_With_Multiple_Params

The parameters have to be separated by a ; for it to take effect. Here ‘env’ and ‘param’ are 2 params that my automation scripts accept.

So there’s the solution for it.Hope this post was helpful to some.

I love Jenkins for it’s plug-ability & wide range of solutions to commonly faced problems/requirements. Simply  superb!

Alright guys.. Have fun… Enjoy 🙂

This is VJ signing off!

 

 

 

Responsive Design: How device usage is changing the way we build websites

Nice article …Rebloggin this one..

Seven hours behind.

How many web enabled devices do you own? A very simple question. A phone? A tablet? A laptop? A desktop? These are just the basics. The most common. There are also web enabled TV’s, games consoles, and even fridges. Slowly more and more devices are connecting to the web.

As a developer or stakeholder, you will want your website to be visible and fully functional on as many devices as possible. The problem is that devices have different sized screens with different numbers of pixels.

If you write your website to work on desktop devices you don’t want to have to write another whole website to do exactly the same thing for mobile devices. Doing so would be a massive waste of time and resources that could be better used somewhere else.

That being said, you don’t want mobile device users to see a broken site that just doesn’t…

Python Tutorial: Dictionaries (Key-value pair Maps) Basics

Nice one..Rebloggin this..

Shafiul Azam's Weblog

Dictionary in Python is a dat type also known as map. You may be already familiar with them, if using Associative Arrays in PHP or Hash-tables in C++ or Java. You may imagine a dictionary as an array, where instead of numericalindexes (the first element of array is indexed as 0, the second element indexed by 1 and so on) you can use stringindexes. Each element of a map is accessed (or, indexed) by an unique key, and so they are known as key-value pairs. Dictionaries are not sequences, hence maintains no left-to-right order.

Dictionaries are not sequences, hence maintains no left-to-right order.

Operations

You can create a map by the declaration: var_name = {key:value}

Code after “>>>” in following examples means: you need to type the code in Python command line. Any line not beginning with “>>>” indicates an…

In the shell, what is “ 2>&1 ”?

1 is stdout. 2 is stderr.

Here is one way to remember this construct (altough it is not entirely accurate): at first, 2>1 may look like a good way to redirect stderr to stdout. However, it will actually be interpreted as “redirect stderr to a file named 1“. & indicates that what follows is a file descriptor and not a filename. So the construct becomes: 2>&1.
