Introduction

“A single hole can sink an entire ship.”

The idiom is much more relatable to this blog on the importance of software quality assurance. Like a single hole, a single flaw in your software can make you lose a chunk of potential traffic.

And the biggest real-life examples are Netflix, Amazon, Spotify, and LinkedIn because they have noticed massive reductions in traffic due to a single bug. Below are some stats:

• Amazon noticed a 30% reduction in traffic in 2013 due to a software bug, disallowing customers from accessing the website.
• Netflix reported half of the traffic reduction in 2016 due to a software bug.
• LinkedIn experienced a 70% reduction in traffic because of a bug disallowing users to log in.
• Spotify, an audio streaming and media service provider, also lost massive traffic due to software bugs.

But what made these big fishes come back and dominate their industry? It was timely assuring the quality of their software and performing rigorous testing.

Now that you know why rectifying even a single bug is important, this blog will introduce you to all the essentials of quality assurance.

What is Software Quality Assurance (SQA)?

Software Quality Assurance is the parallel process to the software development life cycle. It assures that the software product is ready to release for public use when fully developed. The SQA process begins while starting the software development and continues till the release. Quality assurance is an ongoing process of testing the software on different quality standards to improve software quality.

The objective of the SQA is to detect all the bugs and errors before the software release and rectify them so that the end product becomes flawless.

Software Quality Assurance has four basic principles, which include:

1. Preventing Defects

The primary principle of Software QA is to detect defects in the software product in the development stages. Detecting and rectifying bugs proactively will reduce technical debt and save you from the traffic reduction threat. And opting for SQA will help you win customers’ heart because it not only fixes symptoms but also identifies and eliminates the root cause of bugs.

2. Continuous Improvement

Software is developed once, but new features are always added, which might create a bug; this demands continuous attention. When implementing corrective, functional, or recommended updates or indulging in code refactoring to enhance software functionality, it becomes imperative to re-test. Due to this, continuous improvement becomes one of the core principles of Software QA.

3. Stakeholders Contribution

Collaborating with all stakeholders, including clients, developers, testers, the QA team, and the project lead, keeps everyone on the same page. It makes software development and rectifying flaws process easier and swifter.

4. Risk-based Approach

Lastly, Software Quality Assurance ensures identifying and highlighting the potential risks associated with the software product. This way, SQA can rectify those bugs that could hamper your software product.

Importance of Software Quality Assurance for Your Business

Not only is rectifying bugs important, but several other benefits make Software QA worth spending. Keep reading the software quality assurance importance to understand why you must invest in it.

Guaranteed High-quality Software

Once the software undergoes quality assurance, it becomes reliable, user-friendly, and highly efficient. The process ensures that the software abides by quality standards and requirements.

Prevents Downtime

Nothing could be more catastrophic than your software failing to meet its target audience’s demand. Another potential importance of software quality assurance is the prevention of downtime because reviving it once it has stopped functioning could require more investment than before, but if the software has undergone quality assurance, software failure will be a thing of the past.

Develops Competitive Software

Software released without testing will have failures, like disallowing users from accessing or crashing while accessing it. But with Software Quality Assurance and performing granular testing, you can be assured that your software is reliable, usable, portable, and functional.

Secured & Compliance-abided

Software Quality Assurance ensures efficient, trustworthy, and secure software that meets industry standards like data privacy and security. There are several compliances like HIPPA, GDPR, and regulatory compliance.

Dominates Market & Sector

A high-quality software that remains intact no matter how many users access it, doesn’t crash in any environment, and caters to the requirement makes a dominant position in the market.

Diminishes Maintenance Cost

With Software Quality Assurance, you do not need to wait for users facing issues and then rectify them. It automatically gets detected during the development phase and rectified then. This means no long-term, hefty maintenance cost.

What are Different Types of Software Testing for Quality Assurance?

Now you know the importance of software quality assurance but do you know the success of Software Quality Assurance depends on how testing has been performed? Well, it does! But it is also important to consider which testing is essential for your product or particular functionality.

Unit Testing

It is a type of testing that undertakes a single code and tests it meticulously to see if everything works as expected. Such testing assures flawless functioning of the task for which the code is written and tested. Most skilled software QA testers perform unit testing and then only advocate for that functionality to be flawless.

Integration Testing

Another testing type followed by unit testing is Integration. It tests how two different units or functions work together and if there are any performance glitches. Integration testing aims to notice any faults when two or more functions interact.

Functional Testing

When the software passes the functional testing phase, it is said to be ready for public use. The reason is; the software’s functions are marked to deliver the desired outcomes as users expect. This is necessary testing because your users will be satisfied if the product meets their expectations.

Regression Testing

This testing type is also said to double-check what was previously done and see whether it works as expected. For instance, a codebase is tested, and a new feature is introduced for which fresh code is written. When testing the new code, the already tested code is re-tested to see any bugs pop up.

Performance Testing

It is a type of testing that measures the speed, responsiveness, and stability of a device or software product under a certain workload. This will help identify the bottlenecks related to performance.

Security Testing

One of the crucial and must-needed testing for business owners is security testing. This unveils security vulnerabilities, threats, and loopholes in your software application. Besides, running security tests even helps prevent malicious attacks. As a business owner, you must consider a company that performs such testing.

Usability Testing

Another great testing type that most business owners should consider is usability testing. Such testing undertakes the actual use of software products to see whether the functions work as expected. There will be two parties; one using the product and the other taking notes of the software behavior.

Compatibility Testing

A business owner would be happy if their software product works swiftly across databases, devices, operating systems, networks, and hardware. Besides, compatibility testing is all about ensuring that the software product works as expected in varied hardware & network setups. A software product’s success depends on how your software is compatible with meeting and growing demands of its users.

Automated Testing

This is the only software testing that executes without manual intervention. It ensures all the functionalities perform well before the software is made live for public use. By leveraging different automated testing practices, you get faster feedback on failures. Aligning with the “Fail Fast, Fail Early” principle, it allows you to achieve software quality that is unmatched by other testing types.
