Processes And Protocols Of Software Testing In Software Development

Software Testing

The influence of software in business is huge and software technology is advancing rapidly to improve life standards, enhance business prospects and stay competitive. It helps to improve the efficiency and effectiveness of the company’s activities, and reduce workload. A smooth and foolproof functioning of the software is vital to ensure uninterrupted functioning and efficiency. So, to ensure superior quality of the product and avoid any software failures, software testing and quality assurance is a must. A Long Island software development company can help businesses with software testing and make sure that it functions the way it should and that users get the desired results.

What Is Software Testing and Why Is It Important?

Software testing refers to the process of determining whether the actual software product meets the expected requirements and making sure that the product has no defects. It aims to identify and evaluate whether the developed software application meets the Business Requirement Specifications. The objective of this process is to detect errors, gaps, or missing requirements in comparison to the actual requirements. When a software is developed, there may be errors in any phase of its lifecycle. There are high chances that the final code has errors of functionality and design. For the identification of the issues before the occurrence in the critical environment, it is a vital to perform the testing of software.

A properly tested software product ensures dependability, security, and excellent performance. It helps save valuable time, is cost-effective and ensures customer satisfaction.

Software testing is a continuous process of verification and validation to deliver an excellent product. Every phase of the test examines the performance and efficiency of the software application and makes sure that it aligns with technical and business parameters. Testing of the software is also important in the final quality assurance report. Quality assurance helps to monitor the software engineering processes and methods used in a project to ensure proper quality of the software.

Why Is Quality Assurance Important?

When a software is developed, its quality assurance is also as important as software testing. While software testing focuses on the technical aspects of the systems, quality assurance deals with the software specifications. Quality assurance evaluates the development and the test cycles, including the techniques, tools, and processes.

Quality assurance checks the standard of software components. It is a process that involves data collection and documentation. It focuses more on preventive measures than restorative practices. The quality assurance process is used all across the development cycle and also prevents any bugs in the development process.

Types of Software Testing

Software testing is conducted in two ways, manual and automated.

Manual Testing: As the name says, it is the process of testing the software manually and needs no automation tools. It is a test from a user perspective and it detects the errors and bugs manually through different levels of testing. For manual testing the tester follows a plan, case and scenario-based execution to complete a software test.

Automated Testing: Here the tester writes a script and uses external software to perform the test. It helps double check the quality of the product. The manually tested software also undergoes automation testing to ensure better accuracy and cost-efficiency.

Different Methods of Software Testing

White Box: It is also called structural testing, as it is based on the application source code structure. It ensures that the internal performance of the software is aligned with the specifications.

Black Box: It is a method that measures the functionality of the application. It is an interface-level trial-and-error software test also renowned known by the name input-output/data-driven test.

Grey Box: This is combination of White Box and Black Box testing methods. The tester requires both the knowledge and accessibilities of the other two methods to perform the Grey Box test. It is a hybrid method that provides better test cases in the software test process from the user’s perspective.

Software Testing Models

Waterfall Model: It is a well-structured software development model that follows a distinct approach to perform the testing. In this model, the software will be divided into multiple phases and works on each stage – Requirements-Design-Implementation-Verification-Maintenance. It is a simple engineering model to perform software testing with ease and efficiency.

Iterative Development: In this model, each component goes through repeated test processes. It involves three steps – formulate, test, evaluate. Right after the iteration of each part, a new model will be developed that undergoes testing.

Agile Methodology: It is an advanced model with an incremental testing approach. As the requirement varies with time, no other models could offer a flexible development/test cycle. The agile model is more resilient to incorporate changing conditions and this model gives more importance to customers and developers. Here, every component is tested immediately and reduces the risk factor in the process.

Extreme Programming: It is similar to agile methodology and promotes short test/development cycles. The project is divided into numerous pieces, and each piece is subjected to the user test at its release. Integrating the immediate response from customers, this type of test works mostly for the project that needs frequent changes.

Software testing ensures that the software is free from any errors and helps to bring improvement in the software. If businesses fail to test their software, then it can have a negative impact. A 2017report by Tricentis reveals that global enterprises faced a loss of 1.7 trillion in assets and affected 3.7 million people across the globe. In 2018, across the US, poor software quality incurred a huge loss of $2.84 trillion collectively. Therefore, software testing and quality assurance is important.
