Software is a collection of programs, data and instructions that tell a computer or device how to perform specific tasks. In simple terms, software makes hardware functional by providing it with instructions.

A program is a set of instructions written in a programming language that tells a computer how to complete a specific task or solve a problem. Programs are created by developers using languages like Python, Java, C++, etc.

In simple words, programming refers to writing instructions that tell the computer how to conduct particular tasks as well as solve problems.

What are the main components of any application

Most applications are made up of the following key components, here below 8 are: GUI (Graphical User Interface): The part of the application that users interact with. Roles: Define user permissions and access levels. Backend Processes: System-generated programs that run in the background. Database: Stores application data. Reports: Present data in a structured and readable format. Logs: Record system activities and errors for monitoring and troubleshooting. Interfaces: Enable communication between different systems or modules. Business Rules: Define application logic and validations. Example: Facebook age validation.

What is the difference between a Process, Project, and Product

Process A process defines how work is standardized and carried out. Its main purpose is to improve the quality and consistency of a project. Project A project is a temporary effort undertaken to create a product. It has a clearly defined scope, objectives, and timeline for delivery. Product A software product is the final outcome of a software project. It focuses on delivering value to users and does not have a fixed time period like a project.

What is software testing and why is it important

The process of software testing evaluates a software application to find defects while checking whether it meets requirements and performs according to expectations. The process helps find bugs at an early stage and creates better software while making products reliable and secure and cutting development expenses which leads to higher customer contentment.

When was Software Testing considered an important part of the SDLC, and Why

The Y2K problem involved a situation where, after 1999, the year wasn't changing to 2000; systems were failing, and bank accounts were displaying "00". Indian IT companies tested and solved this issue. Since then, software testing has been made compulsory in the IT industry and essential part of the SDLC.

What does quality mean in software testing

Quality in software means high user satisfaction and a low level of defects. It reflects the software’s ability to consistently meet customer needs in terms of: Requirements - The software does what it is supposed to do. Cost - Delivered within the agreed budget. Delivery Schedule - Delivered on time. Service - Provides support and assistance as promised. Maintenance - Can be easily maintained and updated. Increasing quality can directly lead to higher productivity and efficiency.

How do customers define quality in software products

From a customer’s perspective, quality means: Delivering the right product - Ensuring the product fulfills its intended purpose. Satisfying customer needs - Meeting the functional and non-functional requirements of the user. Meeting customer expectations - Providing the features and experience the customer anticipates. Treating every customer properly - Offering respectful, helpful and responsive service.

What is the supplier’s perspective on software quality

From a supplier’s perspective, quality means: Doing the right thing - Choosing the correct actions and processes. Doing it the right way - Following proper methods and standards. Doing it right the first time - Minimizing errors and rework. Doing it on time - Delivering products or services as scheduled.

How do you measure software quality

Software quality can be measured by evaluating several key factors: Correctness - How well the application meets requirements. Reliability - Whether or not the software functions without errors. Efficiency - Optimal usage of system resources (memory, CPU/network). Maintainability - Ease in Updating/Fixing Software. Usability - Ease of following us interactions. Security - The level of protection the application provides to its users against un-authorized access to data. Performance - Speed, Responsiveness, Scalability under different operating conditions. By following metrics including defect density, mean time to failure, code coverage and user satisfaction, organizations can be able to measure the software quality and act suitably on it.

When to start Software Testing

Software testing should start from the requirements phase and continue throughout the development lifecycle until release.

What is the goal of Software Testing

The main goal of software testing is to find bugs as early as possible and make sure that they are fixed before release. To verify that the software meets customer requirements and expectations.

What is the objective of starting Software Testing early

Early testing reduces cost and rework time by identifying defects at an early stage. Requirement-related defects, if detected later in the Software Development Life Cycle (SDLC), result in a much higher cost to fix.

When does software testing need to stop

Software Testing should stop when the acceptance level of remaining bugs reaches a point where the cost of further testing exceeds the benefits. This stage is known as the "Optimum Point". Software testing may also stop due to the following reasons: Project deadlines are reached. The test budget has run out. All planned test cases have been executed. Functional and code coverage have reached an acceptable level.

Participants of Software Testing

Customer - Participates in Alpha and Beta testing User / End User - Validates the software from a real-world usage perspective Developer - Performs Unit Testing Software Tester - Plans, Designs, and Executes Test Cases Project Lead / Manager / Auditor - Monitors quality, Process, and Compliance

What are common Misconceptions about Software Testing

Anyone can test software without proper knowledge or skills. Testing can find all bugs in the software. More testing always means better quality. Only testers are responsible for software quality. Testing is only done at the end of development. Manual testing is outdated and less important than automation.

What skills are required for Software Testing

Key skills for software testing include attention to details, analytical thinking, knowledge of testing types and communication skills no further any programming language required for starting Software Testing as beginner.

Can non-technical people join Software Testing

Yes, non-technical people can definitely join software testing. You don’t need any advanced programming skills to start. Key skills like attention to detail, curiosity and good communication are enough for most entry-level testing roles.

Software Testing Explained Simply

What is Software Testing in simple words

Software Testing is the process of executing a program or software application with intend to finding errors. It helps ensure the completeness, correctness, security and overall quality of the developed application.
Software testing acts as a destructive process for better construction meaning that by identifying defects, we can improve the reliability and performance of the software.
Software testing involves validating both positive scenarios (expected behavior) and negative scenarios (unexpected or invalid inputs).

Types of Software Testing

Software testing is generally divided into two main categories - Manual Testing and Automation Testing, can also be classified based on purpose or level.

Manual Testing - Test cases are executed manually without any automation tools using only excel sheet.
Automation Testing - Test cases are executed using automation tools or scripts like Selenium.

Other Specialized types of Software Testing

API Testing - Ensures APIs work correctly and data is exchanged properly.
Performance Testing - Checks Spike, scalability (Load, Stress, Endurance), speed, stability etc.
Mobile Application Testing - Tests apps on multiple devices, OS versions, and screen sizes.
Security Testing - Detects vulnerabilities and protects against unauthorized access.

Why Software Testing Is Important

Software testing ensures that the product or application is free from any error(like defects, bugs) and meets customer or business requirements and specifications.
Software testing helps identify faults and removing these faults improves the reliability of the software.
By identifying and fixing bugs before the software becomes operational - software testing significantly reduces the risk of failure in production.
Software testing enhances the development process by providing feedback to developers, improving code quality and ensuring a more stable and maintainable product.

Conclusion

Software Testing involves executing software applications to find errors while testing their completeness and correctness and security and overall quality. The process tests two things, which are expected system behavior and system operation under invalid input conditions. The main types of software testing are Manual Testing, which testing needs to be done without using automated testing systems and Automation Testing, which testing requires the use of testing tools or scripts. Organizations use specialized testing methods, which include API Testing, Performance Testing, Mobile Application Testing, and Security Testing. The value of software testing comes from its capacity to discover and fix defects while it strengthens system reliability and decreases operational hazards and boosts the software development process through developer feedback.
