Software Testing Tutorial

Software testing is an important part of Software Development, in which it checks that the software works as expected with the help of Software testing techniques. As developers grow from beginners to more experienced ones, it becomes even more important to understand the various types of testing, methods, tools, and best practices that can be used throughout the development process.

In this Tutorial, we will see the important parts of the Software testing topics that we are discussing here in detail.

What is Software Testing?

Software Testing is a method to assess the functionality of the software program. The process checks whether the actual software matches the expected requirements and ensures the software is bug-free. The purpose of software testing is to identify the errors, faults, or missing requirements in contrast to actual requirements. It mainly aims at measuring the specification, functionality, and performance of a software program or application.

Software Testing is an important part of the Software Development Lifecycle, which includes many more Types of Software Testing.

Manual Testing

Manual Testing is a technique to test the software that is carried out using the functions and features of an application. In manual software testing, a tester tests the software by following predefined test cases. In this testing, testers make test cases for the codes, test the software, and give the final report about that software. Manual testing is time-consuming because it is done by humans, and there is a chance of human errors.

There are different Methods to Implement Manual Testing, but it is broadly classified into three types of manual testing:

• Black Box Testing: In Black Box Testing technique, the tester or the QA analyst will only check the functionality of the particular module or particular method or sometimes the entire application by providing the different test cases manually. 
• White Box Testing: In White Box Testing technique, the person will check the internal structure of the system like designs, coding, etc., manually. Here, the development team will review the entire coding part line by line to ensure the correctness of the code.
• Gray Box Testing: In Gray Box Testing this technique is the combination of both white-box testing and black-box testing. Here, the internal structure of the application is partially known by the tester

Automation Testing

Automated Testing is a technique where the Tester writes scripts independently and uses suitable Software or Automation Tools to test the software. It is an Automation Process of a Manual Process. It allows for executing repetitive tasks without the use of a Manual Tester.

• It is used to automate the testing tasks that are difficult to perform manually.
• Automation tests can be run at any time of the day as they use scripted sequences to examine the software.
• Automation tests can also enter test data compare the expected result with the actual result and generate detailed test reports.

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.

Here are the Seven 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

Software Testing Tutorial

In these tutorial we are covering the Basic level to advance topics which is need to learn the Software Testing, one by one we are discussing here in detail:

Software Testing Can be Divided into Two Steps:

Software testing mainly divides into the two parts, which is used in the Software Development Process:

1. Verification: This step involves checking if the software is doing what is supposed to do. Its like asking, “Are we building the product the right way?“
2. Validation: This step verifies that the software actually meets the customer’s needs and requirements. Its like asking, “Are we building the right product?“

Prerequisites

Testing is an important part of the software development process, and it happens in different stages throughout the project. As a developer, it’s really helpful to understand what happens at each stage so you can create software that’s solid, reliable, and easy for users to enjoy. Every phase plays a key role in making sure the final product works as it should.

Importance of Software Testing

• Defects can be Identified Early: Software testing is important because if there are any bugs they can be identified early and can be fixed before the delivery of the software.
• Improves Quality of Software: Software Testing uncovers the defects in the software, and fixing them improves the quality of the software.
• Increased Customer Satisfaction: Software testing ensures reliability, security, and high performance which results in saving time, costs, and customer satisfaction.
• Helps with Scalability: Software testing type non-functional testing helps to identify the scalability issues and the point where an application might stop working.

Why Learn Software Testing?

Here are the following that it is important to learn Software Testing:

1. Helps to create reliable software: Software testing is compulsory to provide facilities to the customers like the delivery of software applications which require maintenance costs, and need to be more accurate, consistent, and reliable.
2. Helps to deliver quality products: It is very important to check the quality of the product. Quality products delivered to the customers help in gaining their profitable and effective output this can be done by using software testing methods.
3. Helps to achieve effective performance: Software testing is required for the effective performance of the software application or software product.
4. Ensures application is failure-free: Software testing ensures that the application should not result in any failures because the cost of fixing is larger in the later stage of the development of software.
5. Helps to detect bugs: Software testing points out the defects and errors made during the development phase which helps individuals receive quality products.
