The chronicles of a new tester

The general mentality in the software testing industry is ‘Negative thinking is one of the most desired attributes of a software tester’. Ever since my sophomore days I aspired to be a software tester. I wondered if being an optimist would hamper my chances of success in the testing field. Many questions stormed my mind. Some of them were:

1. Does this field belong only to negative thinkers?

2. Is negativity the first criteria to become a software tester?

3. What will be the nature of the teams I work with?

4. Is this profession going to change my attitude?

5. If yes, then what kind of a life am I going to lead?

A lot of times I felt like I was passionate about a profession that did not suit me. Keeping all my apprehensions aside, I continued working towards my goal and left no stone unturned in becoming the tester I dreamt to be.

When I practiced test case writing I would come up with at least 10 negative test cases against 1 or 2 positive test cases. For example, I wrote 30 negative test cases and just 2 positive test cases for a simple ‘Change Password’ scenario. This ratio of 1:15 further increased my ‘positive – negative approach’ dilemma. Eventually, I started to believe that I needed to be more of a negative thinker than a positive thinker.

Determination got me into this field.  I have completed 6 months in an independent testing firm and this period has changed my approach towards testing. Working with vastly experienced people in a positive work environment has answered all my queries.

My new approach is

1. Testing doesn’t belong to negative thinkers at all. It belongs to people who can think along multiple directions.

2. Only people with a positive approach can survive in this field. There is no space for negativity.

3. This profession definitely impacts your behaviour outside office; it enables you to think in a 100 different ways about any situation. You can predict 100 different outcomes of an action or incident. You can come up with a wide range of solutions to any problem. So even if there are changes, they are all good.

When I look back, I wonder, where I went wrong. What made me think that? What caught me off guard?

The answer is -wrong terminology-I got stuck in a game of words!

It is not about 2 positive and 30 negative test cases; it is about 2 valid and 30 invalid test cases I brainstormed in 32 creative ways.

I believe, that the terminology ‘positive’ and ‘negative’ test cases should be refrained since they have a tendency to affect the psychology of testing in a negative way.

For me, in the battle of positive and negative thinking, the winner will always be positive thinking, creative thinking!

Testing the Mobile Apps explosion

It won’t be long before it becomes A-android, B-Blackberry, C-Cupcake, D-Donut,-E-Éclair, F-Froyo, G-Gingerbread, if anything, they are words that probably half the planets population (approx. 3.2 billion people) is well versed with. Not only that another 700 million would be over the next 3 years! If you haven’t guessed it by now…I am referring to the explosion of mobile devices into our lives.

At the core of this explosion in mobile devices and here I mean smartphones and tablets; is the innovation in the field of processors. With processing speeds of these mobile devices increasing dramatically, the demand from users to run complex applications has also gone up. Business users want to have the ability to manage their personal and professional lives through a single interface and have apps that allow them to do this. Add the speed at which innovation in devices, processors and OS takes place and it is not a pretty picture for app. manufacturers.

So, what does all of this mean to you if you are an App. manufacturer or an enterprise trying to create mobile apps for your workforce or customer base?

Some of the areas of impact include:

  • A constant need to keep your app. updated with the latest OS upgrades/ devices in the market
  • Build high secure applications that lend peace of mind to users/ administrators
  • Build apps. that are not very heavy on the device resources (for optimum performance)
  • Constantly upgrade/ enhance your application to keep users engaged

Roll out apps at a speed which would put Formula 1 drivers to shame! Well, just joking on that last one there but for the ones that work in this space, you know what I mean!

Over the years of managing the Quality Assurance programs of multiple Fortune 500 companies and having setup a Mobile Testing Lab fairly early on within this space, I want to share the basic methodology that can be used to mitigate risks for you when developing/ deploying your mobile apps.

Mobile Configuration Optimization
Choose an optimum no. of configurations to test your app on using statistical techniques like Classification tree, Orthogonal Arrays, etc.
Mobile Test Automation
Automate as much of the core testing as possible right from the get go. We have experienced a reduction between 50-70% in the testing effort while ensuring complete coverage across devices. Automation built in on the right design principles also leads to high reusablity of scripts.
Mobile Performance Testing
A holistic approach to performance testing should cover areas such as volume testing, endurance testing, performance monitoring, soak testing and testing under real time scenarios.

An in depth whitepaper has also been written on Mobile is changing the face of Software Testing.I would love to hear from readers on their learning’s when developing or testing mobile apps. Please feel free to write to me

Reducing dependence on automation engineers to manage test automation!

I have always wondered what would it be to separate test automation and automation engineers. Considering that Test Automation has always been treated as the holy grail of testing! Enterprises that have managed to achieve high levels of automation in the testing process have enhanced productivity exponentially while improving coverage and thus reducing risk. This has translated into automation engineers holding  design approaches close to their heart and controlling scripting tightly. Given this dynamic, the adoptions of test automation have remained low over the years.

Test Automation today has transitioned from a “Record and Playback” mode to a virtually “Scriptless” mode thus enabling rapid on the go Test Automation

It has resulted in enterprises automating testing to be oblivious to tool specific coding thus making automation suites maintainable and resource independent. However, scriptless automation frameworks still have many missing links. For example, most scriptless automation frameworks  demand extensive Business User involvement particularly to test the technology enablement. There is a possibility it takes longer than acceptable time to market. Among many causes for greater time to market, one cause is extensive manual testing of the solution. It hamstrings the time taken to market since there is heavy dependence on business analysts (from business or IT) in QA (test design and execution). There is a strong dependence on skilled & expensive technical resources for automation. There is a need to manage spikes in demand for QA resources which results in increase of QA costs.

Considering these dynamics, the next stage in the evolution of test automation is driving in the direction of Business Process Model based test automation that aims at synchronizing Operations, Product Management and Quality functions.

At Zen Test Labs we are innovating with multiple products in this space. Our flagship test automation framework, ZenFRAME is one such example. ZenFRAME improves BA and business testers productivity while reducing dependence on technology teams by up to 40%. The GUI enables most non-technical users to create automated test cases faster  thus resulting in close to 33% lesser creation time, read our whitepaper to know how you can implement a business Process model for you QA environment. Would love to hear thoughts from everyone…

Top 6 solutions for software testing failures

The cost of software testing is still not valued by its worth. Although it is a critical investment companies avoid spending on testing because they don’t realize the ROI on testing and/or a quantifiable cost of quality. The most common complaints against testing that we repeatedly hear are:

  • It is a necessary evil that stalls a project the closer it gets to a release
  • It is too costly, time consuming without any guaranteed outcome
  • Many a times regression testing is not effective to identify new defects

Having worked on a number of testing projects over the past 12 years, I realize why there is a high tendency to look at testing with such a skeptical eye. I would like to share what we have learnt over time.The top six points in our view to improve the effectiveness of manual testing are:

6. Reducing effort and time in Test Documentation

A lot of teams spend unnecessary time detailing test scenarios during the planning phase which are rarely referred to after 2-3 rounds of testing. This increases maintenance overheads and reduces flexibility and coverage in the long run thus resulting in inefficient testing. Post the initial 6-8 months a large % of test scenarios are outdated and require the same effort in updating. Instead of detailing each and every step for every test scenario, one can cover it with test conditions and the expected results.

5. Focusing on breadth and depth of testing

Many a times when execution is not prioritized the depth of testing takes lead over breadth. By aiming at covering more breadth, we align testing with the business objectives. By doing this the teams aim at being effective first and then efficient. Breadth referring to covering positive  critical cases (across the application) that are frequently used by end user.Depth referring to covering all the test cases for a module.

4. Testing, a continuous activity

Many companies look at testing as a one-time investment. They outsource/ execute in-house once during the start of the development of the product and then rarely test it during the maintenance phases. The primary reason is invariably budget driven and goes onto harm the quality of the product when not tested after newer versions. For every minor release one should ensure all the regression test cases are executed and for every major release all the high and medium priority test cases are executed at least once.

3Remembering the objective of testing

The key objective of testing is to break the system and not to prove that the system works as per the requirements.This has a direct impact and can improve testing effectiveness and the number of defects one will find. It is often observed that many senior testers habitually start proving that system is working as per the requirements which is against the primary objective of testing.

2Strategize Test optimization

Coverage is important but not at cost of redundant test cases. Test optimization is an intelligent way to ensure test coverage in less time. That’s why testing teams need to collaborate more with the development teams. Understanding the high level design and structure of the application makes testing more effective. In development, one of the main principles followed is reuse. So, we can use the same principle while testing the same code which is reused. Why not optimize and test the class/object once and just test the implementation of the class/object on other screens/modules. If the test cases are reusable maintainable and scalable it is an additional advantage to roll out in time and under budget.

1. Focusing on the Business for which you are testing

Testing cannot be done in isolation. Business priorities and challenges are equally and in most of the cases more important than testing needs. One thing I have learnt is that testing cannot drive business decisions, business drives testing most of the times. Aligning testing to the business requirements results in a disciplined and ready to market high quality product.

These are some of the solutions with which I could overcome testing failures. Do share yours if you have new solutions or methods
