    Let us quickly start with software testing fundamentals for beginners.


    What is Software Testing?

    Software testing is the systematic process of confirming that software or applications meet technical specs, operate without errors, and satisfy user needs.

    Purpose: It identifies and corrects software issues, ensuring correct, efficient, and secure performance, and meeting user expectations.


    Methods: Software Testing Comprises Two Essential Steps:


    1. Verification: Verification focuses on confirming that the software performs its intended functions accurately. In simpler terms, it asks, "Are we building the product correctly?" Verification ensures that the software aligns with its design and technical specifications.

    2. Validation: Validation ensures that the developed software aligns with customer or user requirements. It evaluates whether the software is the right product for its intended use. In other words, it asks, "Are we building the right product?" 

    In summary, software testing enhances software quality, achieved through verification and validation processes.

    Software Testing Significance: Why is it important?:


    Here are some most convincing reasons why software testing is important for your application or software program.

    1. Early Bug Detection: Software testing identifies and fixes bugs before software delivery.

    2. Customer Satisfaction: Reliable, secure, high-performance software saves time, and costs, and satisfies customers. 

    3. Scalability Checks: Non-functional testing pinpoints scalability issues and potential application failures.

    4. Cost and Time Savings: Regular testing during development prevents costly post-launch issue resolution. 


    Need for Software Testing

    The importance of software testing becomes evident through historical incidents showcasing the devastating consequences of software bugs:

    • In 1985, the Therac-25 radiation therapy in Canada malfunctioned due to a software bug, causing lethal radiation doses and resulting in injuries and fatalities.
    • 1994 witnessed the crash of a China Airlines Airbus A300 due to a software bug, leading to the tragic loss of 264 lives.
    • In 1996, a software bug erroneously credited the U.S. bank accounts of 823 customers with a staggering $920 million.
    • 1999 saw a $1.2 billion military satellite launch failure caused by a software bug.
    • In 2015, a software bug in the F-35 fighter plane compromised its target detection capabilities.
    • The same year, a software bug led to the crash of the Bloomberg terminal in London, affecting 300,000 financial traders and necessitating the postponement of a £3 billion debt sale.
    • Starbucks was compelled to close over 60% of its U.S. and Canada outlets due to a software failure in its POS system.
    • Nissan had to recall one million cars from the market in response to a software failure in the airbag sensory detectors. These real-world incidents underscore the critical need for rigorous software testing.

    Types of Software Testing:



    About Manual and Automation Testing


    • Manual Testing:

      • Hands-on, manual testing without automation tools.
      • Testers act as end-users to identify software bugs and unexpected behavior.
      • Different stages: unit, integration, system, and user acceptance testing.
      • Test plans, test cases, and scenarios ensure comprehensive testing.
      • Includes exploratory testing to discover errors.
    • Automation Testing:

      • Involves writing scripts and using automation software to test products.
      • Automates manual processes for quick and repeatable test scenario execution.
      • Ideal for regression testing and assessing load, performance, and stress.
      • Enhances test coverage, accuracy, and efficiency.
      • Saves time and money compared to manual testing.

    Apart from these, software testing is majorly divided into 03 broader categories –

    • Functional Testing:

      • Validates software systems against functional requirements.
      • Ensures the application adheres to specified functional criteria.
      • Includes Unit, Integration, System, and Smoke testing, among others.
    • Non-functional Testing:

      • Checks applications for non-functional requirements like performance and scalability.
      • Assesses aspects such as usability, portability, and stress.
      • Comprises Performance, Stress, and Usability Testing, and more.
    • Maintenance Testing:

      • Involves updating software to meet changing customer needs.
      • Helps to conduct regression testing to verify new changes don't harm existing functionality.

      • White Box Testing:

        • Assesses the internal structures, code, and algorithms of the software.
        • Focuses on verifying the logic and design, looking "inside the box."
        • Examples include Statement Coverage, Decision Coverage, and Path Coverage.

        Black Box Testing:

        • Helps to evaluate the functionality of the software without examining internal code.
        • Concentrates on inputs and outputs, treating the software as a "black box."
        • Includes Functional, Non-functional, and Regression Testing.

        Grey Box Testing:

        • Combines elements of both White Box and Black Box Testing.
        • Testers possess partial knowledge of the internal code, focusing on functionalities.
        • Balances internal logic examination with external behavior assessment.


        Software Testing Levels


    Unit Testing:

      • Focuses on testing individual units or components of the software.
      • Aims to ensure each unit performs its designed functions correctly.
    • Integration Testing:
      • Involves testing groups of integrated units to uncover interaction faults.
      • Check how individual units work together within the system.
    • System Testing:
      • Helps to evaluate the complete, integrated software/system as a whole.
      • Assesses system compliance with specified requirements.
    • Acceptance Testing:
      • Tests the acceptability of a system for delivery and business requirements.
      • Ensures the software is ready for deployment.

    Best Practices for Software Testing


    Continuous Testing: Test each part of the software as soon as it's ready. This helps find problems early and improves how the software works and looks.
    Involve Users: Developers should ask users what they need in the software. This helps make sure the software does what customers want
    Divide Tests: Split tests into smaller parts. This saves time and helps analyze tests and results better.
    Metrics and Reporting: Share goals and test results with the team. Special tools can show project metrics and give an overall view of the project's health.
    Don't Skip Regression Testing: Don't forget to check if everything still works as it should. This is a very important step
    Programmers Avoid Writing Tests: It's best if programmers don't write test cases. They might be too focused on their own code. Others should do the testing
    Service Virtualization: Simulate systems and services that aren't ready yet. This way, teams can start testing sooner and try different scenarios without changing the original setup.
