Information from QA Consultants: Testing Types Classification

Tests can be classified as follows: by scope, purpose, life-cycle phase.

By the basic of positive scenario, software testing can be categorized into 2 types:

  • Positive testing
  • Negative testing

1. Positive testing is intended to verify that a software application is working correctly against the valid input data. A test fails if an error occurs during negative testing. This is a sign that the application does not work as desired even in an ideal environment. (Moreover, it can be supposed that the program will be functioning much worse under favorable conditions). To speed up the testing process, several tests cases are integrated, though this may make it difficult to detect defects, however, the risk is offset by the significant time savings.

QA consultants have huge expertise in software testing & QA area, therefore, you can expect them to find a perfect solution to any problem with development/testing/deployment of your products.

2. Negative testing (invalid testing) focuses on the evaluation of the application’s behavior to make sure that it is functionally correct. In this
testing, invalid data is passed to a test so that to check if the program can gracefully handle it.  

As usual, there are almost twice as many negative test cases as positive ones. Unlike positive test cases, negative ones should not be integrated, because it may lead to an erroneous assessment of the application’s behavior and, besides, defects may be missed.

Testing can be classified by type of software application:

Web-application testing is the kind of activity associated with compatibility testing  (especially cross-browser testing), performance testing, automated testing by using a variety of testing tools.

Mobile application testing is also the process during which the app is validated for compatibility in an unlimited number of devices and it is aimed at optimizing the performance of the program, at that in terms of efficient energy consumption; mobile app testing is frequently automated by using mobile device emulators.

Desktop application testing is a traditional testing type within this classification. It depends on a domain of the application, architectural peculiarities, key quality characteristics, etc.

There are many other types to be classified, for instance, console application testing GUI-application testing, server applications testing, client applications testing and so on and on….

But what you cannot do without – usability testing services that are meant to prove that the chosen app meets all your needs and is easy to use, operate, maintain, update.
