Why Quality Assurance is Important in Web Application?

What is quality assurance?



Quality Assurance (QA) is a vital aspect of software development, which:

  • Certifies and guarantees a fully functioning user interface

  • Provides quality user experience

  • Allows initial feedback to be collected from end-users using the web application


Overall, quality assurance ensures that applications follow proper steps and procedures before the deployment to end-users.

Where is quality assurance implemented?


Quality Assurance is a standing prerequisite for most software application projects.

QA practices are implemented in most types of development projects, regardless of the underlying software being used.

When a web application is developed for a customer-facing application, it's vital for it to pass through a state of testing and analysis to certify the functionality of the website.

Why is quality assurance important?


Web applications are now an indispensable aspect of businesses around the world. More businesses are now migrating from out-dated applications to a new type of web-based business model.

With such colossal volumes of applications that need to be hosted online, there is now a dire need for quality assurance — a need for measurable and quantifiable analysis — that can help in gauging the quality of these web-based applications.

The importance of this cannot be overemphasized, as the development life cycle of web applications cannot be completed without proper testing.

In fact, this vital process is just as important as the development phase itself. However, it’s frequently misunderstood to the point where people even ask if it’s necessary.

Proper quality assurance on a web application project helps to determine and analyse the quality and usability of a website which will be visible to the end-users (the consumers).

The user experience understood within the QA testing phases will help to provide ways to deliver maximum usability and subsequently an optimal user experience.

Furthermore, it helps to identify bugs that couldn’t have been determined during the initial development and design phases.

Therefore, security holes and risks that may have caused data leaks or data breaches could be detected and corrected for the overall better performance of an application.

When should quality assurance take place?


In the past, quality assurance testing has generally been brought into the process relatively late in the development cycle.

The best way to prevent disaster and minimize the risk of defects while also maximizing end-user experience is by introducing software and quality assurance testing throughout the entire development process.

Therefore, QA testing should be undertaken routinely, both whilst developing the application and even after it’s complete.

Whilst doing so, it allows the opportunity to continually locate and correct any issues that might crop up within your website or web application.

Catching defects early in the life cycle of a web application development will be much more cost-effective than fixing them later on after the product is almost fully developed or released.

If QA specialists are involved from the very beginning, they will help ensure that the product doesn’t progress too far along with bugs that will impact its quality, which is both more difficult and more expensive to resolve once a project reaches their final stages.

QA Testing Prevents Disasters


The best way to prevent disaster and minimize the risk of defects while also maximizing end-user experience is by introducing software and quality assurance testing throughout the entire development process.

QA testing prevents disasters. Most times, conflicting development methodologies complicate the tracing and visibility of information between teams.

During testing, especially deployment and integration, it is critical that software teams know what they are testing for, and the reasons for the tests.

This includes knowing what changes have been made to which data, what triggers the change (requirements, specifications, risk mitigations, etc.), which software builds and patch to use, and which hardware abstraction levels are required for specific test methods.

In the other direction, the teams responsible for implementation need visibility to test results so they can make updates and resolve issues uncovered in testing.

Solutions are available today that help to track and manage the complex and concurrent tasks involved in the application development and quality assurance process.

How Quality Assurance and Software Testing Work Together


While fixing software defects is essential, it is important to remember that software testing and quality assurance are interwoven which represent two sides of the same coin.

You cannot talk about quality assurance without mentioning application testing. Besides mitigating and eliminating errors, it is vital to determine what ‘quality attributes’ should be in place, because when it comes to user's experience, anything that does not meet the needs of the end-user could be assessed as a defect.

Conclusion


Quality assurance testing is about more than fixing problems. It’s about establishing quality standards and implementing the checks and balances needed to ensure the end-product meets said standards.
