Careers in Software Testing

Those who say software testing as a career is inferior to software

development need to get a sanity check done. Software testing is as important as

software development activity. Do you know how much a simple software mistake

can cost you? Rs 1 lakh, 2 lakhs, 3 lakhs...?? No clues?



$125 mn!!. Yes, in the year 1999 when NASA lost the $125 million Mars orbiter, a
spacecraft that was meant to be launched in space to study Martian climate,

weather, CO2, etc. This happened due to a flaw in its software.

Actually, there were two different teams involved in the mission-Lockheed

Martin Engineering which built and developed Mars Orbiter for NASA and the other

was the NASA flight team-both of which used their own units of measurement

during the operation. Lockheed Martin engineering team used English units of

measurement while NASA's team used the conventional metric system for a key

spacecraft operation, which caused the navigation information to go haywire and

the spacecraft crashed. Had proper procedures for the navigational software been

followed, this irregularity might have been detected and the loss could have

been averted. This is a classic example that shows the importance of having good

software testing practices at place and the consequences one might have to face

for not following them.

Arun Rao, Vice President, Global Human Resources, AppLabs A Testing professional needs to understand the technicalities of databases, languages, GUI frameworks and OSes. He also needs to have analytical sense of mind and the ability to break open applications that seem to be perfect, and that how he can find loopholes in the applications. Today, organizations don't just want testers to have knowledge of testing but also require to have business domain knowledge, as well.

Mukesh Sharma, Founder & CEO, QA InfoTech The demand for niche skills like SOA testers are on the rise. Also, there are lot of avenues in test automation areas - scripting skills in the tools languages like VB, Java and other scripting languages like Perl, Shell, Python etc. Technical resources with capabilities to evaluate automation tools, create automation framework and reusable components are on demand. There is always a demand for good performance testers who can analyze performance test results, identify the bottlenecks and recommend tuning techniques.

Today organizations have realized the importance of software testing and they

do not want to face the embarrassment of their product or solution failing just

because of a small mistake that gets overlooked.

Ramanan R V, Head of Global Delivery and Chief Software Architect, Hexaware Technologies Software defects are so prevalent and detrimental that they cost the U.S. economy an estimated $59.5 billion annually -about 0.6% of the GDP, according to a study commissioned by the Department of Commerce's National Institute of Standards and Technology (NIST) in 2002. So Quality assurance is a very decisive stage as testers should guarantee that all functional needs are met even when there's higher load.

Ananda rao Ladi, Vice President, MindTree Specializations like security testing, SWOT testing, performance testing are the ones one can pursue in addition to create a lane for himself in the industry. There is a lot of need for testers to have industry domain specialization. For example, if you have been testing in the insurance world, you will be valued very high. Specializations with respect to type of testing or specialization with respect of the industry domain can be a good thing to pursue. Unlike developers, testers are expected to know everything about the product and application. Therefore, testers can even become a domain specialist, or a business analyst or even a product manager.

Nowadays companies work at avoiding such defects from the start, so it is not

just about detection of defects anymore. That's why they adopt standards like

CMM, ISO, Six Sigma etc and taking all these developments as a cue, some IT

companies have begin to leverage the power of good quality assurance practices,

which has opened several new avenues in the field of software testing. Some

companies have started positioning themselves as Independent Software Testing (IST)

service providers who provide specialized software testing services to other

organizations, to test their products or to device software testing practices

for their processes.

Shreyas Merchant, PMP Associate Practice Director - Applications & Integration Services, Fujitsu Consulting India Today clients are very cognizant of the cost implications of poorly tested products or solutions and strive to avoid this situation under all circumstances, since these directly result into financial as well as opportunity loss. Comprehensive and effective testing is the only “knight in shining armor” that could help businesses to plug these holes successfully. The only challenge is the current gap between demand-supply of Professional Testers which is widening across all geographies.

Manish Rathi, Head — Delivery Management, Version 1.0/ New Venture Services, GlobalLogic In software testing area any knowledge which is gained as part of courses can just act as a starting point; however the major evolution happens on the job. Testing pros should look for opportunities to get hands-on experience which will help them sharpen their software testing skills. Software testing is more about being applied and pragmatic rather than just following academic experience. My organization while assuming that pros have a good academic back ground looks for a good attitude & ability to work in fast-paced environment.

Looking at the pace of the recent developments happening in this field, there

is no denying the fact that software testing is fast emerging as a lucrative

career option; it enables rapid career growth, and has substantially moved away

from the myth that if somebody can't make a career in development, then only

does he settle down into testing.

Opportunities



Although testing is an integral part of SDLC, emphasis is given to keep it

independent from development. In the past, testing was carried out after

development was over. Today this has changed and the testing activity starts

right from the requirements definition stage. In many organizations today, 'test

driven development' is the norm. This increased focus on quality has greatly

increased the scope of testing activity. Testing has become a serious career

option for software engineers; in fact a fresher or some one with 2-3 years of

experience, might eventually find testing to be the fastest way to gain domain

expertise. This niche area created demand for testers and quality assurance

professionals for myriad of opportunities. Careerwise and also remuneration

wise, the growth opportunities for a professional in testing domain has

increased. Testing is now compared at par with other IT services in terms of

revenue for companies and also for the kind of remuneration and career growth it

has on offer for a professional to enter this domain.

However, software testing should not be taken as an alternative to software

development. And as a career option it is not just open for software

professionals but also for professionals from other industry domains, as today

software testing has not just been confined to application testing but to the

whole process of development and also the need to adhere to quality norms.

Because of that, testers do not have to look at the propriety of the software

code, but have to look at all the scenarios that the software will be subjected

to when it is deployed across production systems or when it will be deployed at

the client's end. This not only requires software knowledge but also requires

you to have to have the knowledge of the domain itself. For example, if you have

to test a BFSI application, you not only have to check the UI or security or

load but the actual requirements of the domain you are testing the application

for. For eg, for the BFSI domain, you can use your knowhow of user requirements

in banking and the various working procedures to create test scenarios for the

application.

Harini Raghavan, Senior Software Test Development Engineer, Microsoft India Development Center “Understanding different types of testing (performance, stress, security, etc) as well as knowledge of a few testing techniques, experience in creating test plans and test cases, knowledge of different software development cycles are a plus for a fresher. If one possesses the right skill set with a good technical background the opportunities are plenty. At Microsoft, the developer to tester ratio is 1:1. About half of our annual hiring for Software Development Engineer in Test (SDET) comes through the campus recruiting pipeline.

Shashikant Mohite Chief Manging Director, SQTL The knowledge gained in academia software testing is not sufficient as chances of the person going in depth to study a specific topic is rare. For example, topics like GUI testing, database testing, systems test design may not be taken up in their curriculum. Certifications for software testing help them in gaining additional knowledge about the subject and also in terms of employment. Certifications like CSTE (QAI), CSTP (IIST), ISTQB Foundation Level, ISEB Foundation Level are some of the recognized certifications recognized worldwide.

Skillsets required



The primary skill that one expects from a software tester, apart from

computer science fundamentals, is good problem solving and analytical skills,

ability to understand patterns in problems and creative thinking to fulfill

requirements of a million customers. They should also have skills on test

automation tools for regression automation and performance testing, database

skills, analytical and lateral thinking skills, programming skills, knowledge of

test management and test processes (including test planning, test design, test

execution, defect management and testing metrics), knowledge of the platform

used for developing the application (Microsoft, Mainframes, Java, etc). Software

test engineers need to have knowledge of programming languages like C, C++, VB

and scripting languages like VBscript, Shell, Python, Perl. These skills are in

demand with the increasing demand for automation engineers. The technical skills

should be supplemented with domain expertise also to form a holistic team for

testing. Gaining prior exposure to usage of some of the prominent automation

testing tools from companies like IBM, HP, Mercury etc can boost chances of

employability especially for fresh graduates who aspire to become professional

testers.

Nowadays domain knowledge is being preferred from software testers by the

companies. Professionals coming from different industries like banking, Finance,

Insurance, Retail, etc have strong understanding of business knowledge and

business processes. These people can work as business analysts in software

organizations. They can also help to validate business processes and provide

valuable comments during software requirements and design phase and also devise

requirements for the end user for an application or product.

The visual shows a typical career path for a fresher who can choose either Testing or QA has the growth path.

Automation, non-functional testing (performance testing, security testing,

usability testing, localization testing) are niche areas in testing. One can

learn these skills after getting expertise in the basic testing area. Test

professionals can also learn new test case designs and optimization techniques

to boost their career in this domain.

New trends in testing



New and emerging technologies such as Service Oriented Architecture (SOA),
Software-as-a-Service (SaaS), Cloud Computing, virtualization and advent of

mobile technologies are radically changing the trends in application testing.

Some of the recent trends in software testing domain indicate an



upsurge in:


a) SOA Testing


b) Security testing


c) Testing in Cloud Computing environments


d) Tool based regression automation and performance testing


e) On-demand testing services


f) Risk-Based testing


g) VoIP application testing


h) Health care

Risk-based testing is a new concept. As software organizations face increased

pressure to complete testing in available time, risk-based testing approach is

followed. Due to increase in business complexity, testing scope has been

steadily increasing, but at the same time the testing window remains the same or

is shrinking. In risk-based testing, areas having major business risks are

tested before others. This way, it is ensured that at least business critical

functionality is tested properly.

Anthony D'souza, Director-Testing Business Unit,Tech Mahindra “Although there is an economic slowdown, focus on software quality has not been reduced. In many cases there is a tremendous pressure on IT services providers to do more testing in lesser time. This is resulting in testing attracting some of the finest talent as we see many game-changing methodologies being introduced that are bringing greater efficiencies and provide opportunities to testing professionals. Product testing is a very big market, and many product companies spend upto 50% or more of product development costs on testing products. This trend is a good one for software testers.

Professionals from these domains can become business analysts and quality

testers by lending their expertise for creating test bases for applications.

Having the domain experience helps an individual to understand user requirements

and also to devise test scenarios for applications based on experience, thus

going beyond the manual testing of a code for a given application.

Career path



Software testing professionals have many interesting options today to design

their career path based on individual preferences. One can take a plunge into

the world of business applications by moving into functional testing or keep in

constant touch with technology by focusing on automation testing.

They also have the option to get into ground-breaking areas such as

professional games testing and mobile device testing.

A fresher who enters the industry as a test engineer, can choose the testing

line or else move towards the quality assurance line where he can become QA lead

and then QA manager. A typical career path for a professional tester would

unfold as a junior test engineer, test engineer, test analyst, test lead, QA

manager, followed by program manager/COE head.

Certifications



Academic knowledge in software testing is the starting point which brings in

more awareness of the available career options in IT industry. This needs to be

further augmented with specialized trainings in different areas of testing based

on individual preferences and market needs. Certifications in testing also play

a major role in meeting the industry trends. A stamp of approval from a credible

institute by means of certifications improves the confidence of the employers as

well as clients on the testing professionals. There are several institutes such

as, International Software Testing Qualifications Board (ISTQB), American

Society For Quality (ASQ) and Quality Assurance International (QAI) that offer

vendor neutral certifications. Tool specific certifications are available from

OEMs such as IBM, HP, Borland, etc. Obtaining certifications like CSTE

(Certified Software Test Engineer) from recognized institutions or from online

certification site like Brainbench can help a professional get a competitive

edge over others during recruitment.

There are institutions like Edista Testing Institute dedicated for Quality

and Testing curriculum. Professionals who want to seek their career in software

testing or want to enhance their understanding of various quality standards can

gain certifications from these institutes. For freshers, the organizations

themselves train them on various testing tools and quality standards. But, a

test engineer who has already gained some experience can look forward for a

specialized certification to jump-start his career.

Talking about the requirements in Indian IT industry for software testers,

Pradeep C, CEO of Edista Testing Institute (ETI) says, “Indian market itself

requires 35,000 testers approximately to bridge the gap. And, that gap is

continuously increasing to almost 1,65,000 in the year 2013, as per the



projection.” Thus a professional can safely bet on this niche domain for his
career and having some domain experience behind can be of much demand by

software testing organizations.
