Software Testing Definition
Software testing is a process that ensures whether the current software product matches the expected needs and to find that software products are bugs-free. Software testing involves the execution of software/system components using manual or automated tools to review more than one properties
The main purpose of doing software testing is to identify errors, gaps, or missing requirements as opposed to actual requirements. Some prefer saying, White Box and Black Box Testing are used as Software testing. In simple words, it means the Verification of Application Under Test (AUT). In this tutorial, software testing justifies the importance to the audience

What are the benefits of Software Testing?
The benefits of software testing are as follows:
- Customer satisfaction.
- Product quality.
Cost-effective.: It is one of the major benefits of software testing. Testing any IT project can help you to save your money for the long term. In case if the bugs are caught in the earlier stage of software testing, it is less costly to fix them.
Security: This advantage is the most sensitive and vulnerable of software testing. People are looking for reliable products. It helps in removing attribute factors and problems earlier.
Customer Satisfaction: This is the main purpose of the product to give satisfaction to customers with their quality. UI/UX Testing ensures the best user experience.
Product Quality: This is an important need for any software product. Testing ensures quality products to the customers.
Testing in Software Engineering
The testing process involves checking the software product features programs behavior or requirements in terms of any missing requirements, defects, security, reliability, and performance. According to ANSI/IEEE 1059, testing in Software engineering is a process that ensures whether the current software product meets the expected requirements and or not.
Types of Software Testing
Testing is generally classified into three categories.
- Functional Testing
- Non-Functional Testing
Functional testing is a process, which is involved in the testing of the functional aspects of the software application. When you are doing the functional testing, you need to test every functionality. You have to see if you are getting the desired results or not.
These categories of functional testing are
- Unit Testing
- Integration Testing
- UAT ( User Acceptance Testing)
- Interoperability, SO On
Here are some of the tools information that you can use for functional testing such as Micro Focus UFT (previously known as QTP, and UFT stands for Unified Functional Testing), Selenium, JUnit, soapUI, Watir, etc.
Non- Functional testing is a process, which is involved in the testing of non-functional aspects of a software application such as security, reliability, performance, and usability. it can be performed after a functional test. Through non-functional testing, you can improve the quality of software to a great extent. functional tests can also improve the quality but through non-functional tests, you can make your software even better. This category includes several types of testing
This is not a complete list of types; there are more than 150 types and still adding. All testing types do not apply to all projects, these types are used according to the nature and scope of the project.
Testing Strategies in Software Engineering
Some important strategies of software engineering are here
- Unit Testing
- Integration Testing
- System Testing
Unit Testing: In the unit testing strategy, A programmer tests the unit of the program by following the approach of software testing. It helps developers to determine that the code is working properly or not.
Integration Testing: This strategy focuses on the design and construction of the software and also needs to see that the integrated unit is working properly or not.
System Testing: In the final testing strategy, to check the whole system’s security, functionality, portability, amongst others.
Program testing in software testing is executing a current software program to test the program’s behavior and find bugs. A good program testing is that has a high chance of finding errors. The software program is implemented with the test data to analyze the program’s behavior or response to the test data.
