Strongly typed vs loosely types

By | September 23rd, 2018|

Strongly typed vs loosely typed languages

What is it and what’s the difference

Some programming languages have more checks at the compile time (while building the code), and have checks on method calling, data types, return types and so on

In short you cannot ‘loosely’ use variable types and change them on the go

Examples of such languages would be Java and C#, each variable must be declared with a specific datatype

The opposite off course is loosely typed, where there are no such checks on the compile time

A major reason for that is some languages don’t have to be ‘compiled’ to build code

Such an example would be JavaScript, these languages are called ‘interpreted’ languages

In JavaScript’s example, it’s code is mostly used in browsers, and that’s one of the reasons why some websites look different

They can ‘interpret’ the same JavaScript code differently.

So, mostly ‘compile time’ languages (e.g. Java, C#..) would be ‘Strongly typed’, and ‘interpreted’ languages (e.g. JavaScript) would be ‘loosely’ typed

Never give up

By | September 22nd, 2018|

Never give up

You are defeated only when you give up

I always give an example of a little kid and a wrestler

If the kid keeps coming back to fight, no matter what happens, or how long it takes, eventually he will win

Persistence and being tenacious are fine qualities

A quality of ‘Winners’

In the words of the Great Muhammad Ali:

“I don’t count my sit-ups; I only start counting when it starts hurting because they’re the only ones that count.”

As he said, ‘float like a butterfly and sting like a bee’

What is programming

By | September 21st, 2018|

While learning automation, I feel it’s important to learn:

What is programming?

While there are many metaphors people give, most cannot fit 100%

I am too confused (was confused) how to define programming

A LOT of people just run away from learning to code

One reason is, IMHO, we don’t necessarily teach it in the best way

And a good place to start it, what is programming?

The best answer I found is:

It’s like writing, you take an idea in your head and you write it down

Similarly, in programming you think of an algorithm and write it down

If we broaden this definition, I even call playing Real Time Strategy games ‘programming’

Sure, you’re not writing code, but you are thinking of an ‘algorithm’ to beat another person or ‘algorithm’ (Computer as a player)

Automation batch issues

By | September 20th, 2018|

Automation batch issues

Passes individually but fails in the batch..

This would be an all too common for anyone who has worked in automation

While the reasons for this can be ‘infinite’, here are some common ones I’ve observed on top of my head:

– Dependent test data. When running individually no other script can change the data, in a batch run that is a possibility

– Tool / browser reset. If the previous script failed, the browser was still in error state and the next script starts executing, resulting in failure

– Delay. Browser response time can change when running in a batch, must have dynamic delays before interacting with EVERY object

– Application down. While this might seem a remote possibility, in some cases this does happen in very sbtle ways.

Any other ‘very common’ factor you have noticed?

Standardized platforms for evolution

By | September 16th, 2018|

A key ingredient in my observation for evolution in technology:

A standard platform, here’s why

When a new technology emerges, it takes more than a few people to evolve it

A very large group of people collectively working with it helps in pushing boundaries

Take the PC for example, having a standardized OS on PC (Windows) was one of the main causes that fueled advancement in software development

On the other and, embedded devices (IoT) has been out there around since the PC, but we are far behind there

Embedded platforms were very fragmented and challenging to develop, therefore layers of abstraction were not built there as rapidly

Only in recent years we have seen things like Raspberry pi and so on

The same would go for automation, having a standard platform and building layers of abstraction on top of it would make the difference

The same way standardized JavaScript execution on all browsers has fueled front end platforms like Angular, Sencha and so on.

 

Thoughts?

Community building

By | September 15th, 2018|

Community building, the reason why humanity survived

And a core factor in any idea’s success.

One person alone is weak and fragile compared to other species walking the earth

But one of the reason why we went from the bottom of the food chain to the top is community building

For any idea to gain success, there must be a community around it.

And make no mistake, there is an idea / story behind everything,

Every product, every service and every person is telling a story (weather they know it or not)

So, if you are building a product, build a ‘tribe’ around the idea your product serves

Or whatever you are willing to accomplish, the idea should be worthwhile for at least a few select people

Then build a tribe around it.

Define Leadership

By | September 14th, 2018|

My favorite interview question and answer:

Q: “How do you define leadership”? Ans:

“Leading by example”

This was asked to me when I was interviewing for my current role

I always felt a leader was the one who sacrificed his wishes and wants for his/her tribe

Probably why Simon Sinek’s book: “Leaders eat last” resonated with me so much

I was reminded of this answer yesterday when Tom Bilyeu asked LeVar Burton the same question,

His answer: the EXACT same words I gave my ‘to be’ manager 4 years ago ‘Leading by example’

And BTW, you don’t need to have a ‘lead’/’manager’ title to be a leader

‘Genuinely’ help solve people’s problems, the law of reciprocity will make you a leader

Most leaders in history were a ‘leader’ long before they ever got the ‘title’.

Learning automation steps

By | September 13th, 2018|

Step 1: Install Selenium and implement POM? ABSOLUTELY NOT..

Step 1: Un-learn the crap which is holding you back

Step 2: Learn how software works

Step 3: Lean how to develop algorithms

Step 4: Understand what automation’s goal is and what to achieve from it

Step 5: Install the tool, libraries etc..

Step 6: Take algorithms from Pseudo code to actual running code

Step 7: Develop a simple and messy framework

Step 8: Learn programming best practices

Step 9: Revamp the framework and script a neat one

I know this might be longer and not as easy, but IMHO the right way to do it

I’d rather spend TWICE the time on WHY than on HOW

Automation supporting different application versions

By | September 12th, 2018|

How to manage your code for different UI?

Our automation is reaching yet another level of complexity hence the question..

Elaborating the question:

If we have an application with different versions we support

And there are UI differences across versions (off course), which means different automation code needed,

How to structure your automation code base?

Now off course it would depend on the kind of changes we are seeing.

Here are a few strategies I’ve used / seen / read aboout:

1. Automation code residing alongside production code, in the same repo (@Angie Jones).
– Sounds awesome, never used it. But Angie says it works so I will surely take her word for it!

2. Separate code branches for different versions.
– E.g. for product version 1.0, 2.0 & 3.0, automation code base with a trunk and branches: 1.0, 2.0 and 3.0
– I’ve seen this for prod code, it can get messy, but works

3. Conditions / variables within same branch
– Have conditions within the framework, data selection and POM classes to run based on app version
– I don’t like this. should work in few cases. But things can get out of control fairly quickly and become WAY complex.

Any other ideas you might have?

Adding test data choices and our journey

By | September 11th, 2018|

From add on the fly, to using random data to saving seed data in DB (Link to the story in first comment)

After using seed data which resides in a baseline DB and restoring it when needed,

Now we’ve moved on to the next problem:

How to add data to ‘Six’ baselines, that’s right, one test which has to run on 6 different environments needs the same seed data

We have been adding seed data manually, but for 6 it’s not going to be easy

Since it does not have to be created just 6 times, but every time before we create the seed data on baseline, we test it by creating on the ‘restoring’ DB,

So the number jumps to ’12’ times

The few options we talked about to help with this:
– Use UI scripts to create seed data (for data which is simple)
– Improve the API automation and use it to create seed data, just like UI above
– Finally (which I don’t want to do AT ALL), create data to the DB directly

The last option has many problems, schema across versions is not the same, data creation is not the same, existing data might not be exactly same either..

The brainstorming is going on, but an interesting challenge to have.

Thoughts?

Philly visit and the rocky Stairs

By | September 10th, 2018|

With Rocky motivation..

The two week long Philly visit ended few days ago.

And like each year, did the ‘Rocky thing’ again.

What fascinates me the most about Rocky is persistence.

No one can compete with sheer hard work and persistence

And there is no substitute for it,

No short cuts, no hacks, tricks, jacks, inside edges, cutting corners,

Plain and simple hard work and persistence will ALWAYS take the day.

Because it tells the God / the universe you are willing and ready to pay the price.

And you are granted success.

Handling and becoming unicorn employees

By | September 7th, 2018|

Now you know what a ‘Unicorn’ employee is (See previous two posts)

What to do about it…

For employers:
– If you have a Unicorn on your team or someone who has the potential to become one
– Go out of the way to take care of their interests
– That’s what happens in sports, extraodrinaty talent is paid extraordinarily, and have an extraordinary impact on results
– So the extra mile you go will get returned back many folds

– If you don’t have unicorns (or any) on your team, you are far away from success
– This is the information economy, you can’t muscle your way to success anymore

For employees:
– If you are a unicorn, know your value
– You should not be working for anything less than ‘changing the world’, and be treated as such

– If you are not a unicorn yet
– Put in the effort to become one, it will be all the worth while

Who are ‘Unicorn’ employees

By | September 6th, 2018|

If you guessed unicorn’s don’t exist, well that’s true, but..

Unicorn employees DO exist, and here’s (IMHO) who they are:

0. Attitude – This is a given (hence point 0)
– If this is not understood already, then we have a big problem

1. Technical skills – Skills that will do today’s job.
– They know (or potential to learn) the tool, language, platform you want them to work on.
– Have demonstrated competence in similar areas.

2. The Architect mindset – They don’t think about JUST the current problem
– When developing solutions they solve problem they foresee in coming years.

These two skills are hard to find, now let’s move on..

3. Communication – They talk like a marketing / sales pro
– Can communicate their point of view effectively and are good listeners
– They are social and pros at building relationships

A good software engineer who communicates well is like a singing tree, you don’t see them very often..

And lastly..

4. Leadership – Not a manager, a leader
– Can inspire, instill purpose and drive in their team
– Develop ‘psychological safety’

Now THAT is a unicorn!

The engineers hiring dilemma

By | September 5th, 2018|

Mostly ideal candidates don’t know how to sell themselves, and the ‘not so ideal’ ones sometimes know exactly how to..

Ideal candidates are good with technical skills, they know the’re stuff and are passionate about it

Since they spend more time polishing their skill, might not be as great communicators or leaders

Hence don’t know how to sell, and are difficult to find and persuade

Not so ideal ones lack technical skills, and sometimes make it up by being good at selling

They know how to up-sell and might be good communicators as well

They come up easily in the net, but can be hard to fish out,

And, IMHO, can be equally destructive for your team

So the trick I use is to stick to the few fundamental traits/skills only, and do not compromise on them.

Tomorrow I’ll talk about the candidates I call ‘unicorns’. Want to guess..?

Eleventh Hour Changes

By | August 8th, 2018|

Small code changes at the 11th hour?

It’s always a very tricky question, but here’s how I handled it

There were some fundamental changes we were working on for our UI automation project

We were not able to get to the changes in time and release time was upon us

Despite the very urgent need to check in those changes, we holded off

The dates were changed a few times but still we didn’t try to ‘sneak in’ the change

Deciding against releasing a featue is surely more stressful than this case,

But the fundamentals are the same.

I talk more about this in the linked article:

What is Compatibility Testing

By | August 7th, 2018|

How to do Compatibility Testing?

Wrong question, first let’s talk WHY compatibility testing.

We all know it’s meant to test our AUT’s UI on different front-end platforms (browsers, devices, OS etc.)

But it’s paramount to understand what creates the difference when running on different platforms

Let’s take a web app running on a browser for example,

It would help to understand the different components of a ‘browser’ and what portions are different

Each browser has a different ‘driver’, e.g. Chrome uses the Gecko driver.

This causes it to probably display a piece of JavaScript slightly differently than let’s say Firefox.

I’ve seen compatibility tests meaning “Run ALL tests on each device / combination)

Instead, just run tests which are checking the ‘JavaScript’ or ‘UI’ functionality of your app

The rest will be the same on every browser

Jenkins just for Automation

By | August 6th, 2018|

Jenkins benefits even if you are not using a CI process,

Having the collective results in one place has a lot of advantages

Can get results from different tools (might be using separate ones for UI, API and unit level) in one place

Even for one tool, having all parallel runs in one place is a big blessing

Secondly can have a combined history of all the results (in Junit format used by Jenkins by default)

Thirdly, it allows for parallelization to your tests

To scale your automation, this is going to be a must

Number Four: One can centrally control the automation execution resources from one place

Having parameterization will make things even more easier

Evolution in Automation

By | August 5th, 2018|

Evolution in automation didn’t start just few years ago.

It’s been around for decades and here’s a crude synopsis:

> 1980’s: computers found their way into businesses.

> 1985: First wave of automation tools started.

> 1990’s – Advent of GUI bases OS like Windows 3.0, UI based automation tools start to pop up.

> 1995 onwards: In the race to dominate the UI automation market, eventually WinRunner dominated.

> Around 2000: New technologies like Java jump in; web takes off. New paradigm shift, from desktop to web.

> Around 2004: First version of Selenium RC introduced.

> Around 2005: WinRunner becomes QTP after the acquisition by HP.

> Web has built a lot of momentum, big push to support web UI automation started.

> 2007: Selenium Webdriver’s first version launched.

> 2007 – 2008: iOS v1.0.x released, Android v1.0 released, Mobile is born.

> 2008: Cucumber is introduced.

> 2009: Mike Cohn introduces the Automation Pyramid.

> 2014: Appium v1.0 is launched.

> Meanwhile mobile has taken off, cloud computing is picking momentum and CI/CD is spreading in the backdrop.

> 2016: Jenkins 2.0 released.

> 2018: Docker CE is launched.

Automation ROI

By | August 3rd, 2018|

Automation ROI calculation

It’s not about calculating man hours saved

While automation has a lot of benefits,

Equating time spent by a tester to a machine running the test is not accurate.

Most people (including myself in the past) calculate automation ROI by man hours saved

Automation is provides only data points, they do not necessarily mean a failure.

A person has to interpret the data and conclude if we have a failure.

But then how does automation benefit us?

Learning API automation

By | August 2nd, 2018|

How to learn API automation?

I’d follow the following steps:

1)

Don’t start with instaling an API automation tool

2)

Do NOT START with installing an API automation tool, learn what are API’s first then think about tools.

3)

Understanding how APIs / the HTTP request / response works. Lots of tutorials out there.

A video covering the basics linked in the comments.

4)

Test some sample APIs with POSTMAN.

That would give you an idea of how API calls are constructed and some common responses

You can try using this website as a sample:
https://jsonplaceholder.typicode.com/

5)

Look into learning RestAssured.

There are a bunch of courses out there on it. It can work in parallel with Selenium.

All you need to do is just add the Maven dependency –

P.S.
I’m using RestAssured with spring Boots!

Automation is NOT just UI Automation

By | July 31st, 2018|

TestAutomation != Ui_AutomationOnly;

AutomationInTest == UI_Automation + API_Automation + UnitTests + WhateverYouCanComeUpWith; // This can be a long list

Any mundane test programmed to be checked through a tool would classify under automation

Since UI automation is the most widely implemented form of automation, it has become synonymous with automation

API automation is very valuable and should come directly under an automation engineer’s core responsibilities

Often since we start off ‘not as aware’ about the technology stack, we’re not really sure how API testing is done

Linked article stacks up UI vs API automation to illustrate the benefits.

McCabe Code Complexity

By | July 30th, 2018|

Configurability and complexity go hand in hand

Thanks to Thomas J McCabe for proving this concept

I have to say, over time things do get streamlines when layers upon layers of abstraction are added

But while developing a product, or automation framework, the more configurable we try to make it, the more complex it becomes

For that reason, Thomas McCabe came up with this algorithm to calculate complexity

Embedded / IoT devices standards dictate to keep the McCabe cyclomatic complexity (Code complexity) below 30

It’s not a bad idea to calculate your code’s complexity level and stick to a limit

Makes life a lot easier down the road.

Learn automation or go technical

By | July 29th, 2018|

Want to learn or hire for automation?

“To be technical or not to be, that is the question”..

While speaking at a conference I tried to outline the journey of a tester

While there were a lot of lessons to learn, the premise was to focus on learning the underlying technology

Familiarity with just an automation tool will not bring the results you want, for both, as an employer or as an employee

What you really are looking for is a technical background AND be able to program tests at the same time

DevOps and Tenacity

DevOps and Tenacity

Here’s the relationship..

The differential between the good and the great is Tenacity

The great know to hashtag#NeverBackDown / hashtag#NeverGiveIn, and that’s what makes them great

Success consists of going from failure to failure without loss of enthusiasm (Winston Churchil)

In delivering software there are a lot of unknowns, many things can go wrong, and you’ll never get it right the first few times

So, keep on improving and at an accelerating speed. For which you and your team must be tenacious

And to me that’s what DevOps is, keep improving at speed, keep going from failure to failure without loss of enthusiasm, or simply put ‘fail fast’

Programming an important skill

By | July 27th, 2018|

I’m often asked how to learn automation

On of the most important skill is programming..

Firstly, often times this subject is not approached the right way

Folks attempt at ‘codeless’ or ‘keyword based’ automation at first

IMHO, while it might work for a finite scope and technology stack, generally it’s seen not to deliver

In the end, to do automation well you’ll have to program. there is no way around it

Secondly, learning programming is not about being good with Java or any one language’s syntax

It’s about building the right APTITUDE and the right ATTITUDE

With those two, the language becomes irrelevant. And without them your skill in any language will not create desired results
