Market Scope

Why Software Testing as a career ?

World-wide Software Forecast: India may garner 70% of market inSoftware testing-Gartner Report

Domestic Software Market Check : While the market for softwareservices is growing at an average of about 10-12 percent, testing is growing

at more than 50 percent a year

Nasscom Report

Ample Scope for Research : Software testing still remains an art, due tolimited understanding of the principles of software. We are still using thesame testing techniques invented 20-30 years ago, some of which arecrafted methods or heuristics rather than good engineering methods.

Typically, more than 50% percent of the development time is spent in testing.-Carnegie Mellon University

Analytical approach Programming skills for Software Testing:Knowledge of programming languages is required for unit testing, scriptingskill essential for Automation testing Contrary to software myths

Functional Testing: Creation and execution of test cases /scenarios based on functionality

detailed in Software Design or Software Requirements Regression testing and Automation testing also covered

Segregate the Types of

testing according torequirements

Non-functional Testing: Tests created based on non-functional aspects of applications like

application usability, performance, accessibility , compatibility with severalbrowsers, multi-lingual languages support or database migration

The application needs toadhere to the defined

project requirements orindustry standards

Testing techniques: Risk Based Testing Equivalence Class Partitioning Boundary Value Analysis

Formal methods lead tocomprehensive testing

Domain : Insurance

Specific Applications: Life Insurance & Annuities (Functional Testing) Generic Applications: Corporate Applications (Data warehouse Testing))

A Comparison Testing Types

- 1 4 -

1. Applicable to high-end industries likeSemiconductors, Real-time embedded systems

1. Applicable to industries like Banking, insurancecompanies, Manufacturing units and retail units.

2. More of White Box Testing.Require lot of system knowledge.More of software product testing.

2. More of Black-box Testing.Require more of application knowledge.More of software services testing.

3. More involvement of Hardware systems (Test Rigs)during software testing

3. Less need of hardware systems (Test Rigs) duringsoftware testing. Can carry out with lesser hardware

dependendency

4. Extremely regulations driven testing (Avionics DO178B, Railway Signaling CELELEC EN 51028)

4. Lesser of industry wide regulations.Hence defined more at client levels.

5. Very limited and specific market, hence lessersoftware professionals. Testing methods more or lessdefined.

5. Huge market to explore for opportunities.Plethora of software professionals and fastergrowth. Testing methods still evolving.
