Software Testing: Principles and Practice

This tutorial introduces the seven basic Software Testing Principles that every Software tester and QA professional should know. Background It is important that you achieve optimum test results while conducting software testing without deviating from the goal. But how you determine that you are following the right strategy for testing? For that, you need to stick to some basic testing principles.

Here are the common seven testing principles that are widely practiced in the software industry. To understand this, consider a scenario where you are moving a file from folder A to Folder B. Think of all the possible ways you can test this. Apart from the usual scenarios, you can also test the following conditions Trying to move the file when it is Open You do not have the security rights to paste the file in Folder B Folder B is on a shared drive and storage capacity is full.

We need certain principles and strategies to optimize the testing effort Here are the 7 Principles: 1 Exhaustive testing is not possible Yes! Exhaustive testing is not possible. Instead, we need the optimal amount of testing based on the risk assessment of the application.

And the million dollar question is, how do you determine this risk? To answer this let's do an exercise In your opinion, Which operation is most likely to cause your Operating system to fail? I am sure most of you would have guessed, Opening 10 different application all at the same time. So if you were testing this Operating system, you would realize that defects are likely to be found in multi-tasking activity and need to be tested thoroughly which brings us to our next principle Defect Clustering 2 Defect Clustering Defect Clustering which states that a small number of modules contain most of the defects detected.

By experience, you can identify such risky modules. But this approach has its own problems If the same tests are repeated over and over again, eventually the same test cases will no longer find new bugs. The same applies to software testing. If the same set of repetitive tests are conducted, the method will be useless for discovering new defects.

Testers cannot simply depend on existing test techniques. He must look out continually to improve the existing methods to make testing more effective. Software Testing reduces the probability of undiscovered defects remaining in the software but even if no defects are found, it is not a proof of correctness.

This can be the case if the system is tested thoroughly for the wrong requirement. Software testing is not mere finding defects, but also to check that software addresses the business needs. The absence of Error is a Fallacy i. So that any defects in the requirements or design phase are captured in early stages.

It is much cheaper to fix a Defect in the early stages of testing. But how early one should start testing? It is recommended that you start finding the bug the moment the requirements are defined. More on this principle in a later training tutorial. You might use a different approach, methodologies, techniques, and types of testing depending upon the application type. Myth: "Principles are just for reference. I will not use them in practice.

Test Principles will help you create an effective Test Strategy and draft error catching test cases. But learning testing principles is just like learning to drive for the first time. Initially, while you learn to drive, you pay attention to each and everything like gear shifts, speed, clutch handling, etc. But with experience, you just focus on driving the rest comes naturally. Such that you even hold conversations with other passengers in the car. Same is true for testing principles.

Experienced testers have internalized these principles to a level that they apply them even without thinking. Hence the myth that the principles are not used in practice is simply not true. What is Software Engineer?

 - Я не из севильской полиции. Меня прислала сюда американская правительственная организация, с тем чтобы я нашел кольцо. Это все, что я могу вам сказать. Я уполномочен заплатить вам за. На мгновение в комнате повисла тишина, затем Росио приоткрыла губы в хитрой улыбке. - Ну видите, все не так страшно, правда? - Она села в кресло и скрестила ноги.  - И сколько вы заплатите.

Она не доверяла Грегу Хейлу. Он был из другого теста - не их фирменной закваски. Она с самого начала возражала против его кандидатуры, но АНБ посчитало, что другого выхода. Хейл появился в порядке возмещения ущерба. После фиаско Попрыгунчика. Четыре года назад конгресс, стремясь создать новый стандарт шифрования, поручил лучшим математикам страны, иными словами - сотрудникам АНБ, написать новый супералгоритм.
