Software Testing Tutorial

The Software Testing Tutorial serves as a comprehensive guide for learning Software Testing. It covers all software testing basics to the most advanced concepts, making it beneficial for both beginners and experienced professionals.

Testing is basically a collection of methods to evaluate an application’s suitability for use by a predetermined script. The basic goal of testing is to find application flaws so that they may be identified and fixed.

Software Testing Tutorial

What is Software Testing?

Software testing involves executing a program to identify any error or bug in the software product’s code.

1. This process takes into account all aspects of the software, including its reliability, scalability, portability, reusability, and usability.
2. 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.

Manual Testing

Manual testing is the process of verifying an application’s functionality by client requirements without using any automated techniques. We do not need to have in-depth knowledge of any testing tool to do manual testing on any application; rather, we should have a thorough grasp of the product to quickly create the test document.

Manual testing is further divided into three types of testing :

• White box testing
• Black box testing
• Grey box testing

For more information refer to the article – Manual Testing

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.

Software Testing Principles

Software testing is putting software or an application to use to find errors or faults. We must go by certain guidelines while testing software or applications 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:

1. Testing shows the presence of defects
2. Exhaustive Testing is not possible
3. Early Testing
4. Defect Clustering
5. Pesticide Paradox
6. Testing is context-dependent
7. 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.
