What is Quality Assurance Testing | Types, Significance

In this FAQ post, we will talk about a very common question "what is quality assurance testing" and also will cover its types and significance in the software world.

What is Quality Assurance Testing 

It is the process of using the whole system to test the quality of a piece of software. QA is a part of the software development life cycle, which includes planning, designing, and coding. The QA team tests how well each component works with other components to make sure that there are no bugs or defects in your code. The main goal for this stage is to identify any problems before they become bigger issues later on down the road during production or deployment phases after you've released your application into production environments such as AWS Elastic Beanstalk applications or Heroku apps using the Ruby on Rails framework.

>Quality assurance is a process, not just a tool. It's not just for testers and developers.

it's also for your entire team, who must be involved in the process as they work on their tasks. It should be continuous throughout the project, rather than just at the end of it (like testing). In other words: no one should ever stop doing quality assurance.

QA will never find all errors or defects, but it may help you find problems that would not normally be noticed by human testers. QA is needed for all software development projects, not just those that are large and complex. The quality of your product depends on how well the developers can test their code before they release it to the public. If your customers don't like bugs in their software, then they won't buy from you.

So, what is quality assurance testing and why it matters, well, it is an important part of software development because it ensures that the final product meets all of its requirements. In other words, QA testing ensures that there are no bugs in your software before it goes live. It's not just about ensuring that you've tested everything and found no problems; it's also about making sure that any new builds don't introduce new bugs into your existing code base—and this can only be done by performing proper QA testing on each iteration of development work (or release). 

>There are five levels of testing in QA: unit testing, integration testing, acceptance testing, system testing, and stress testing.

Unit testing: A unit test is a piece of code or code fragment that tests one feature. It's usually written in isolation from other features and can be run independently on its own without affecting any other part of the application.

Integration testing: This type of test checks whether different parts of your software work together as expected, which means it involves integration between several modules or components within your application.

Acceptance testing: An acceptance test verifies whether an end-user can successfully perform all the tasks he needs to perform with your product to use it effectively (for example, entering data into forms). It also covers functionality related to usability and accessibility issues that may not have been addressed during earlier stages of development.

System tests: They check a complete working installation to make sure it is functioning properly, including all installed modules and all program files. For example, a system test of the software might be performed by running a set of scripts that exercise each module in the system and checking their return values. The purpose of this type of test is to ensure that each aspect works as it should.

Stress testing: It involves simulating unusually difficult conditions to determine how well a system performs under those conditions. Stress testing, also called acceptance testing, is a method of determining how well a system performs under unusually difficult conditions. It involves simulating the extreme circumstances that might occur in production and assessing how the system responds. Stress testing can be used to test resilience against unexpected circumstances and recovery from those same conditions. For example, if your application is designed for only one kind of input (for example, customer orders), then you should stress test it to make sure it works properly when presented with an extremely large amount of something else (like an army marching across its screen).


This concludes the topic for this post“what is quality assurance testing”. Quality assurance testing is vital to the success of a software project. This can be done through several methods explained above. We recommend performing QA testing for your product with WeTest wide array of testing procedures and state-of-the-art techniques.
