The world of technology has witnessed unprecedented growth recently, and with it comes the need for top-notch software applications. In this highly competitive realm of technology, staying ahead of the curve means delivering the best results while being cost-effective and saving time.

Software Development Life Cycle (SDLC) emerges as a critical software component to make this happen. SDLC reduces software development costs, enhances quality, and streamlines production processes. It accomplishes these conflicting objectives by following a well-defined plan that mitigates the usual pitfalls of software development projects. With SDLC, you can create software that meets and surpasses your expectations.

An Overview of the Software Development Life Cycle

A typical Software Development Life Cycle consists of the following stages:

• Stage 1: Planning and Requirement Analysis
• Stage 2: Defining Requirements
• Stage 3: Designing the Product Architecture
• Stage 4: Building or Developing the Product
• Stage 5: Testing the Product

The software testing process cycle pertains to the tasks carried out by developers and testers to evaluate the effectiveness and performance of a computer program.

The software development life cycle usually has five phases of testing:

Static Testing

In static testing, developers perform manual reviews of the supporting documents for the software without running the code. Static testing is done to pre-empt defects before introducing them to the software system.

Unit Testing

Unit testing is the phase where specific units, such as functions and procedures, are assessed to ensure their proper functionality. Developers often use white box testing to evaluate the software’s internal structure and code, typically before formal testing by testers. Unit testing is conducted whenever there is a modification to the code, enabling prompt issue resolution.

Integration Testing

Integration testing process involves testing all the program units as a group to find issues with how the separate software functions interact. Through integration testing, the developers can determine the overall efficiency of the units as they run together. This phase is essential because the program’s functionality relies on the units operating simultaneously as a complete system, not isolated procedures.

System Testing

In the system testing phase, the software undergoes its first test as a complete, integrated application to determine how well it carries out its purpose. For this, the developers pass the software to independent testers. These testers are not involved in software development, ensuring that the testing results stem from impartial evaluations. System testing is vital because it ensures that the software meets the requirements determined by the client.

Acceptance Testing

Acceptance testing is the last and final phase of software testing. Its purpose is to evaluate the software’s readiness for release and practical use. Testers may perform acceptance testing alongside individuals representing the software’s target audience. Acceptance testing aims to show whether the software meets the needs of its intended users and that any changes the software experiences during development are appropriate for use. The representative individuals are crucial to this phase because they can offer insight into what customers may want from the software. Once the software passes acceptance testing, it moves on to production.

In addition to the five main testing phases, you may need additional tests to evaluate the software. These tests’ necessity depends on the company you work for and the software you’re creating. These tests include:

1. Performance Testing
2. Regression Testing
3. Usability Testing
4. Compatibility Testing
5. Security Testing

Why is Software Testing Important?

To understand why software testing is important, we need to analyze real-world examples of the consequences of inadequate testing.

Nissan, a well-known brand, recalled over 1 million cars due to a software defect in the airbag sensor detectors.

Test Issues:

Patriot Missile Failure

During the Gulf War, on February 25, 1991, an American Patriot Missile battery in Dharan, Saudi Arabia, failed to intercept an incoming Iraqi Scud missile. The Scud struck an American Army barracks and killed 28 soldiers.

Mars Rover Pathfinder

The Mars Pathfinder expedition was widely acclaimed as a remarkable achievement in the initial days following its landing on the Martian surface on July 4, 1997. The mission’s accomplishments included its innovative “landing” technique of bouncing onto the Martian surface with the assistance of airbags, deployment of the Sojourner rover, and successful transmission of vast quantities of data back to Earth, including the immensely popular panoramic photographs posted on the Web. However, several days into the mission, shortly after the Pathfinder had begun collecting meteorological information, the spacecraft started encountering complete system reboots, causing data loss. The media reported these setbacks using terms such as “software malfunctions” and “the computer was attempting to execute too many tasks simultaneously.

Overflow Issues

Two Disasters Caused by Computer Arithmetic Errors

A Patriot Missile system stationed in Dharan, Saudi Arabia, could not intercept an incoming Scud missile from Iraq, resulting in the tragic deaths of 28 American soldiers when the Scud hit an Army barracks.

Likewise, the cause of the failure of the Ariane 501 rocket was due to critical errors in the software design and specifications of the inertial reference system, resulting in a complete loss of guidance and attitude information. This failure occurred 37 seconds after the main engine ignition sequence started, approximately 30 seconds after the rocket’s lift-off.
It is widely recognized that quality control is crucial when developing software. Failing to deliver software on time or releasing it with defects can negatively impact a brand’s reputation, causing customers to become dissatisfied and possibly lose interest in the product. In severe cases, a single bug or defect can have far-reaching consequences, disrupting interconnected systems or leading to significant malfunctions.

Software quality assurance (QA) testing is an essential component of the software development life cycle, ensuring that the final product meets high functionality and user satisfaction standards. Our online software QA testing course equips students with the knowledge and skills required to conduct effective testing at every stage of the development process. From unit testing to system testing and beyond, our course covers various topics and provides hands-on experience with various testing tools and methodologies.
