Software Testing Tutorial
What is Testing?
Testing is a collection of methods to evaluate an application’s suitability for use in accordance with a predetermined script, however, testing is not able to detect every application flaw. The basic goal of testing is to find application flaws so that they may be identified and fixed. It merely shows that a product doesn’t work in some particular circumstances, not that it works correctly under all circumstances.
Testing offers comparisons between software behavior and state and mechanisms since mechanisms can identify problems in software. The method may incorporate previous iterations of the same or similar items, comparable goods, expected-purpose interfaces, pertinent standards, or other criteria, but is not restricted to these.
What is Software Testing?
Software testing involves executing a program to identify any error or bug in the software product’s code. This process takes into account all aspects of the software, including its reliability, scalability, portability, reusability, and usability. The main goal of software testing is to ensure that the system and its components meet the specified requirements and work accurately in every case.
Types of Software Testing
In this section, we have covered the different aspects of some of the most popular testing types and their subtypes.
Types of Software Testing
1. Manual Testing
Manual testing is the process of verifying an application’s functionality in accordance with client requirements without using any automated techniques. We do not need to have in-depth knowledge of any testing tool in order to do manual testing on any application; rather, we should have a thorough grasp of the product in order to quickly create the test document.
Manual testing is further divided into three types of testing :
For more information refer to the article – Manual Testing
2. Automation Testing
With the use of automation tools or a programming language referred to as automation testing, any manual test cases may be converted into test scripts. We can increase the pace of our test execution with the aid of automated testing as there is no need for human labour. It is necessary to create and run test scripts.
For more information refer to the article – Automation testing
Software Testing Principles
Software testing is putting software or an application to use in order to find errors or faults. We must go by certain guidelines while testing software or applications in order to ensure that the final result is free of flaws. This saves the test engineers’ time and effort as they can more efficiently test the program. We will learn about the seven fundamental tenets of software testing in this part.
Let us see the seven different testing principles, one by one:
- Testing shows the presence of defects
- Exhaustive Testing is not possible
- Early Testing
- Defect Clustering
- Pesticide Paradox
- Testing is context-dependent
- Absence of errors fallacy
Prerequisites
Before initiating software testing its recommended one must have a basic understanding of the Software Development Life Cycle(SDLC) and basic programming.
