Describe some characteristics of a tester.

Question

I want to know some characteristics of a tester in brief.

In many casual conversations with senior level software engineers at Microsoft recently I have heard the same message repeated over and over: finding really good software testers has always been difficult but recently finding great testers has become almost impossible. I have also heard this message from Microsoft and Volt recruiters. In particular I was asked several times last week What makes a great software tester? Microsoft alone consistently has over 400 openings for software testers on a daily basis. Volt has roughly 100 opening for contract testers on any given day. Taking a cue from the title of a well-known management book written by Stephen Covey The Seven Habits of Highly Effective People I decided to sit down and list the characteristics or habits that I'd look for in a great software tester. I put myself in the position of a hiring manager whose product and company depended upon the quality of some hypothetical software system under development. My list ended up having eight attributes rather than seven as in Covey's book but I didn't set out with a predetermined number of characteristics in mind. Here is my list of the eight attributes of a great software tester roughly listed in order of importance although I think all eight are must-have skills. 1. Passion for analysis and testing. 2. Technical skill. 3. Raw intellectual ability. 4. Ability to prioritize and organize. 5. Ability to adapt and learn. 6. Ability to work without direct supervision. 7. Ability to communicate. 8. Ability to understand business strategy. 1. Passion for analysis and testing. The key to success in any job is having an honest passion for what you do. Software testing is primarily about analyzing the work of others. A great software tester will get a greater thrill in writing some test automation which exercises a software application than in writing the application itself. This characteristic is often associated with people who have college degrees in a quantitative field other than Computer Science such as Mathematics or Economics. To a large extent I believe a passion for analysis is primarily an innate rather than learned characteristic. 2. Technical skill. A great software tester must have significant coding skills. Testers may not need skills on par with systems developers but a great tester must have good coding skills in order to understand the system under test communicate with developers and write test automation. Most technical skills can be learned through education (formal college or self-taught) or experience. In either case I believe that at least four years of skill acquisition is a necessary prerequisite for a great software tester. 3. Raw intellectual ability. A great software tester has to be smart. And by that I mean he must have exceptionally strong analytical and logical ability. Software development is essentially an exercise in logic and to operate at a high level in this environment a software tester has to simply be smart. Interestingly intelligence often correlates well with sense of humor and vice versa. 4. Ability to prioritize and organize. The ability to prioritize and organize are generic required skills needed for just about any job but these skills are critically important for software testers. Software development and testing is a highly dynamic and fluid activity where the key variables can change weekly or even daily. The ability to recognize interpret and organize around these frequently changing job environment variables is an essential ability in a great software tester. 5. Ability to adapt and learn. The software engineering field is relatively new (compared with most other forms of engineering) and new technologies appear with a speed that would astonish those not familiar with software. For example the appearance of C# and the .NET Framework in early 2003 completely revolutionized software application development. Great software testers must have an ingrained propensity to be ongoing learners and consistently spend part of every week and maybe even part of every day dedicated to upgrading their skill sets. I performed some research a couple years ago that suggested that a software engineer's skill set half-life is about 18 months — meaning that without a significant upgrade in skills an engineer will be obsolete and not hirable (for leading edge systems development activities) in 36 months. 6. Ability to work without direct supervision. The ability to work effectively without direct supervision is another generic job skill but is a skill that is particularly important for software testers. The requirement for taking independent action — quickly recognizing a technical or business need related to the software testing effort and the ability to know what steps to take without the need of managerial approval (and also the ability to know when not to forge ahead without a management OK) are essential skills. 7. Ability to communicate. A great software tester must have strong written and verbal communication skills. A great tester must be able to read and analyze product documentation write test plans write clear bug reports write coherent status reports to management (both formal report and ad hoc e-mail reports) and have the ability to listen critically and speak rationally in person-to-person meetings. 8. Ability to understand business strategy. The characteristics of great software testers I've listed so far are primarily tactical in nature. The final characteristic of a great software tester on my list is the ability to see the larger picture of a company's overall business strategy. The ability to see the big picture enables a great software tester to actively participate at a level higher than just an individual contributor — instead of merely finding a Priority 2 / Severity 2 bug a great software tester can identify strategic strengths and weaknesses of a software system that can ultimately lead to a business competitive advantage.
