Software Testing Types

Overview

Software Testing, being an integral part of Software Development Life Cycle (SDLC), is used to help identify the correctness, completeness, security, and quality of developed computer software. It is an inherent process to ensure that all the quality standards are met and that the software stands good against the defined business requirements ensuring quality assurance, verification and validation, or reliability estimation.

Training Objective

In this series of articles, we will be looking at different Testing methods, e.g. Ad-Hoc, White Box, Black Box, Unit, Regression, Acceptance, etc. that are used by testers to help aid in validating all the qualities of a software/product. These methods could either be performed manually or automated by means of scripts using automation tools. You will be learning about various software testing types along with advantages and disadvantages.

Target Audience

Software Testing tutorials provides concrete self-learning platform for beginners and will strengthen the fundamentals for intermediate software testing professionals.

1. What is Ad Hoc Testing

   What exactly is Ad Hoc Testing When Will you use Ad Hoc Testing Ad-hoc testing is an unscripted software testing method. Often people confuse it with the exploratory negative and monkey testing. In the domain of software testing the word ad-hoc” means that the test is for a particular purpose at hand only. You cannot use the same

2. What is Acceptance Testing

   Acceptance testing is the last important test among many tests that a developed software system undergoes. Acceptance testing facilitates the end-users to test the software created and ascertain if the developed software actually meets their requirements or not. The functionality of the software is most likely acceptable as software system produced

3. What is Alpha Testing

   Alpha Testing Essentials Alpha testing makes use of prototypes to test the software in its beta stage. However you cannot expect the software to possess complete functionality for which it is designed especially at this stage. This is because alpha testing is usually conducted to ensure that the software that is being developed provides all

4. What is Beta Testing

   Beta testing is the last important step that software developers conduct before they launch new software. Software systems at their beta stages are not fully developed. Hence you should not expect it to be completely functional. However it does give you a first look and a brief glimpse of what it can do for the users before its final launching

5. What is Black Box Testing

   Black box testing is a curious kind of testing as it is somewhat mysterious to the person who is testing the product. The tester will not have any prior knowledge or information about the internal mechanisms of the system that will be tested. In a typical software testing environment the tester will only know what the inputs are and the expected

6. What is Comparison Testing

9. What is Cross Browser Testing

   A web page is created to have an online presence. Visitor traffic is a very important factor for online success. One of the variables that significantly affect the web pages accessibility to the targeted visitors is the web browser. However several browsers are currently in use and each of these web browser interprets the HTML tags differently

10. What is Database Testing

    Database testing is perhaps the most important test that can check the overall functionality of the software. A complete software system will enhance functionality of different aspects like stored functions stored procedures and triggers. Database testing is almost similar to regression testing as it can run automatically to ensure the integrity

11. What is Dynamic Testing

    Dynamic testing or dynamic analysis is an intricate process of inspecting and evaluating software applications as the user uses them. In sharp contrast static tests are conducted on an application when it is not in use. Dynamic testing evaluates the software applications that work under different environments. Software testing is an intricate

12. What is End-to-End Testing

    Software testing is an important aspect of software quality assurance. It represents the final process to ensure the correctness and fineness of the product. A quality software product always increases the customer confidence and satisfaction. In other words a premium product means zero defects bugs and errors which are derived from a better

13. What is Exploratory Testing

    Is exploratory testing similar to an ad-hoc test or monkey testing Among software testers there is admittedly still some confusion with regard to the term exploratory testing" .  The confusions lie in its technicalities; An exploratory test is almost similar to monkey testing or an ad-hoc testing and these 3 testing methods

14. What is Functional Testing

    Functional testing is an efficient method of testing an application to validate its stability.  It is almost similar to black box testing. Functional testing is a common method that almost all software testers use to validate a given set of software applications. This is a popular testing method just like white and black box testing. Topics

15. What is Incremental Integration Testing

    Incremental integration testing  encompass the basic concepts of integration testing.  It is continuous or repetitive testing of a software application as new and fresh functionality is advised. You may need different aspects of software application’ s functionality that are independent to work separately before you complete all parts

16. What is Install and Uninstall Testing

    Installation and Uninstall testing is generally accomplished by a software test engineer with the concurrence of a configuration manager CM .

    Regression test is a powerful tool designed to test the application after the introduction of changes. The basic concept behind regression testing involves testing procedures that ensure the software’ s ability to perform intended tasks even with improvements or modifications. Regression testing is also a form verification test because it

24. What is Sanity Testing

    Sanity testing is a cursory test to confirm if a particular software produces the desired results or not. This implies that the software has already passed other kinds of testing before they can undergo sanity testing. It is important to note that sanity test  is not as in-depth as other kinds of testing.  Topics Why Sanity
