16 Software Testing Questions and Answers:

1 :: A good software tester should be Intelligence?

Intelligence.
Back in the 60's, there were many studies done to try to predict the ideal qualities for programmers. There was a shortage and we were dipping into other fields for trainees. The most infamous of these was IBM's programmers' Aptitude Test (PAT). Strangely enough, despite the fact the IBM later repudiated this test, it continues to be (ab)used as a benchmark for predicting programmer aptitude. What IBM learned with follow-on research is that the single most important quality for programmers is raw intelligence-good programmers are really smart people-and so are good testers.

2 :: A good software tester should be Skeptical?

Skeptical.
That doesn't mean hostile, though. I mean skepticism in the sense that nothing is taken for granted and that all is fit to be questioned. Only tangible evidence in documents, specifications, code, and test results matter. While they may patiently listen to the reassuring, comfortable words from the programmers ("Trust me. I know where the bugs are.")-and do it with a smile-they ignore all such in-substantive assurances.

3 :: low cunning. Street wise is another good descriptor?

"low cunning." "Street wise" is another good descriptor, as are insidious, devious, diabolical, fiendish, contriving, treacherous, wily, canny, and underhanded. Systematic test techniques such as syntax testing and automatic test generators have reduced the need for such cunning, but the need is still with us and undoubtedly always will be because it will never be possible to systematize all aspects of testing. There will always be room for that offbeat kind of thinking that will lead to a test case that exposes a really bad bug. But this can be taken to extremes and is certainly not a substitute for the use of systematic test techniques. The cunning comes into play after all the automatically generated "sadistic" tests have been executed.

4 :: A good software tester should Tolerance Chaos?

Tolerance for Chaos.
People react to chaos and uncertainty in different ways. Some cave in and give up while others try to create order out of chaos. If the tester waits for all issues to be fully resolved before starting test design or testing, she won't get started until after the software has been shipped. Testers have to be flexible and be able to drop things when blocked and move on to another thing that's not blocked. Testers always have many (unfinished) irons in the fire. In this respect, good testers differ from programmers. A compulsive need to achieve closure is not a bad attribute in a programmer-certainly serves them well in debugging-in testing, it means nothing gets finished. The testers' world is inherently more chaotic than the programmers'.

A good indicator of the kind of skill we arelooking for here is the ability to do crossword puzzles in ink. This skill, research has shown, also correlates well with programmer and tester aptitude. This skill is very similar to the kind of unresolved chaos with which the tester must daily deal. Here's the theory behind the notion. If you do a crossword puzzle in ink, you can't put down a word, or even part of a word, until you have confirmed it by a compatible cross-word. So you keep a dozen tentative entries unmarked and when by some process or another, you realize that there is a compatible cross-word, you enter them both. You keep score by how many corrections you have to make-not by merely finishing the puzzle, because that's a given. I've done many informal polls of this aptitude at my seminars and found a much higher percentage of crossword-puzzles-in-ink afficionados than you'd get in a normal population.

5 :: A good software tester should be Tenacity?

Tenacity.
An ability to reach compromises and consensus can be at the expense of tenacity. That's the other side of the people skills. Being socially smart and diplomatic doesn't mean being indecisive or a limp rag that anyone can walk all over. The best testers are both-socially adept and tenacious where it matters. The best testers are so skillful at it that the programmer never realizes that they've been had. Tenacious-my picture is that of an angry pitbull fastened on a burglar's rear-end. Good testers don You can't intimidate them-even by pulling rank. They'll need high-level backing, of course, if they're to get you the quality your product and market demands.

6 :: What makes a good software tester?

1. Know Programming. Might as well start out with the most controversial one. There's a popular myth that testing can be staffed with people who have little or no programming knowledge. It doesn't work, even though it is an unfortunately common approach. There are two main reasons why it doesn't work.

(1) They're testing software. Without knowing programming, they can't have any real insights into the kinds of bugs that come into software and the likeliest place to find them. There's never enough time to test "completely", so all software testing is a compromise between available resources and thoroughness. The tester must optimize scarce resources and that means focusing on where the bugs are likely to be. If you don't know programming, you're unlikely to have useful intuition about where to look.
(2) All but the simplest (and therefore, ineffectual) testing methods are tool- and technology-intensive. The tools, both as testing products and as mental disciplines, all presume programming knowledge. Without programmer training, most test techniques (and the tools based on those techniques) are unavailable. The tester who doesn't know programming will always be restricted to the use of ad-hoc techniques and the most simplistic tools.

Taking entry-level programmers and putting them into a test organization is not a good idea because:

(1) Loser Image.
Few universities offer undergraduate training in testing beyond "Be sure to test thoroughly." Entry-level people expect to get a job as a programmer and if they're offered a job in a test group, they'll often look upon it as a failure on their part: they believe that they didn't have what it takes to be a programmer in that organization. This unfortunate perception exists even in organizations that values testers highly.

(2) Credibility With Programmers.
Independent testers often have to deal with programmers far more senior than themselves. Unless they've been through a coop program as an undergraduate, all their programming experience is with academic toys: the novice often has no real idea of what programming in a professional, cooperative, programming environment is all about. As such, they have no credibility with their programming counterpart who can sluff off their concerns with "Look, kid. You just don't understand how programming is done here, or anywhere else, for that matter." It is setting up the novice tester for failure.

(3) Just Plain Know-How.
The programmer's right. The kid doesn't know how programming is really done. If the novice is a "real" programmer (as contrasted to a "mere tester") then the senior programmer will often take the time to mentor the junior and set her straight: but for a non-productive "leech" from the test group? Never! It's easiest for the novice tester to learn all that nitty-gritty stuff (such as doing a build, configuration control, procedures, process, etc.) while working as a programmer than to have to learn it, without actually doing it, as an entry-level tester.

7 :: A good software tester should be Honest?

Testers are fundamentally honest and incorruptible. They'll compromise if they have to, but they'll righteously agonize over it. This fundamental honesty extends to a brutally realistic understanding of their own limitations as a human being. They accept the idea that they are no better and no worse, and therefore no less error-prone than their programming counterparts. So they apply the same kind of self-assessment procedures that good programmers will. They'll do test inspections just like programmers do code inspections. The greatest possible crime in a tester's eye is to fake test results.

9 :: A good software tester should Know the Application?

Know the Application.
That's the other side of the knowledge coin. The ideal tester has deep insights into how the users will exploit the program's features and the kinds of cockpit errors that users are likely to make. In some cases, it is virtually impossible, or at least impractical, for a tester to know both the application and programming. For example, to test an income tax package properly, you must know tax laws and accounting practices. Testing a blood analyzer requires knowledge of blood chemistry; testing an aircraft's flight control system requires control theory and systems engineering, and being a pilot doesn't hurt; testing a geological application demands geology. If the application has a depth of knowledge in it, then it is easier to train the application specialist into programming than to train the programmer into the application. Here again, paralleling the programmer's qualification, I'd like to see a university degree in the relevant discipline followed by a few years of working practice before coming into the test group.

10 :: A good software tester should be Hyper-Sensitivity to Little Things?

Hyper-Sensitivity to Little Things.
Good testers notice little things that others (including programmers) miss or ignore. Testers see symptoms, not bugs. We know that a given bug can have many different symptoms, ranging from innocuous to catastrophic. We know that the symptoms of a bug are arbitrarily related in severity to the cause. Consequently, there is no such thing as a minor symptom-because a symptom isn't a bug. It is only after the symptom is fully explained (i.e., fully debugged) that you have the right to say if the bug that caused that symptom is minor or major. Therefore, anything at all out of the ordinary is worth pursuing. The screen flickered this time, but not last time-a bug. The keyboard is a little sticky-another bug. The account balance is off by 0.01 cents-great bug. Good testers notice such little things and use them as an entree to finding a closely-related set of inputs that will cause a catastrophic failure and therefore get the programmers' attention. Luckily, this attribute can be learned through training.
