The terms “testing” and “quality assurance” go hand in hand when it comes to software development. Since they are so closely related, they are often mistaken for using them interchangeably. Contrary to this belief, they are entirely different from each other in the technical world.

In this article, we will take a journey to break down the two terms from the point of view of the tech world, then will move on to find out the difference and maybe will settle down in finding a common ground.

What is Software Testing?

The process of software development requires evaluation and verification which is a check for software that is working up-to-date. Most importantly it confirms that the software is working under the guidelines as it is supposed to.

By the means of testing, the business owners are able to estimate the risk factors that are associated with the software launch.

The basic idea behind testing is to analyze the accuracy of the software that was built through the channel of mind mapping.

It catches the software drawbacks, which leads up to fixing bugs at the initial phase cuts down the development cuts and generates higher performance.

Types of software testing

Following are the types of software testing that are used for different purposes:

  • Acceptance testing: this type of test verifies if the whole setup is working as it is supposed to or not. It analyzes whether your business goals are being aligned with the software results and it is verified once it meets the user requirements. Some of the most common acceptance tests are User acceptance testing, business acceptance testing, alpha testing, and beta testing.
  • Integration testing: this type of testing analyzes a different set of modules of the same software setup and tests them as a group. It assesses the system’s conformity with the distinct functional specifications. This test clubs the unit and system testing together. The main aim of this testing is to check the functional flow between the different units in software.
  • Unit testing: this test breaks down the testing into more fragments. This test validates the functioning of each unit of the software code and checks if it is meeting the expectations or not. This test is done during the later stage of the development phase of the software. It is similar to WhiteBox testing. If this test is done properly, it can result in saving a lot of money as well as time.
  • Functional testing: it is the kind of test that is usually done by the QAs and it determines the functional aspect of software according to the prerequisite requirements. Some of the typical examples of functional testing are smoke testing, regression testing API testing, UI testing, and so forth.
  • Performance testing: during this testing, it mainly checks the responsiveness and stability when the workload is imposed on the software hence analyzing its performance. The test determines the speed, accuracy, robustness, and size of the application, this has a proportionate impact on the browser, network, response time, CPU memory consumption, and kinds of errors.
  • Regression test: when changes are made in the existing application, running this test determines the issues that got generated with the new implications that may hamper the launch of the software. Re-execution of this test analyzes the proper functionality of the concerned software.
  • Sanity testing: this test is a quick scan of the analytics of software. While running this test, it distinguishes the unique false results instead of pooling all sets of errors. This provides a quick check of functionalities of calculations, systems, computer programs, and so on.

What is quality assurance?

Quality assurance determines the proper chain of actions that are being carried forward that ensures delivery of the service or the product is matching the benchmark of the anticipated level of quality.

In this process, possible errors resurface and it is fixed in a way that might also prevent the forthcoming bugs during the software development cycle.

Quality assurance is among the most important phases in the lifecycle of the software development chain and it demands the consolidated efforts of the whole project team.

By enhancing the product or service’s quality, you will be able to establish a competitive advantage in the market.

Types of quality assurance

  • Regression testing: the tester analyzes the performance of the software when the new piece of code is added in order to know if it still functions the same without further interruption to the existing framework.
  • Mobile testing: as the name suggests, the testing is done to determine the performance and functioning of the cellular devices that spots light on mobile-related queries such as incoming calls, screen gestures, or multiple application interfaces.

This testing is rather different and also challenging since a cell phone device has a different set of characteristics that must all be analyzed before the final showdown.

  • User acceptance testing: this test also falls under quality assurance testing. Here, user experience and device performance are managed in the context of balancing out unforeseen shortcomings.
  • Data conversion testing: it checks the smooth functioning of the different applications that interact with each other hence determining the failings. It tells about the compatibility between the two software.

Differences between Software Testing and Quality Assurance

  • When quality assurance is concerned it is involved at every stage of the software development lifecycle, whereas software testing is done when the whole setup has been written.
  • In quality assurance, the determination is done prerequisite to standing upon the agreed standard quality guidelines, while on the other hand, software testing is done when analyzing the functionality of the application or the service as per the request by the user.
  • Primary focus on quality assurance services is on the alignment of the product to the user’s expectations. On the other hand, software testing determines the working of the software and resurfaces the bugs in it.
  • Quality assurance is a game of management to ensure the beneficial implementation of the anticipated quality objectives of the company. It is a wide field that includes tools, policies, and training that are coherent to a standard product.

Contrary to this, testing is itself a small portion of the quality assurance strategy itself.

Relationship between Software Testing and Quality Assurance

When quality assurance and software testing are clubbed together they are together called Quality Control. It is a management approach that makes sure to identify errors in software while using different sets of software testing.

The more precisely done tests will reveal better results hence the quality of the product or service will enhance.

To ensure the high quality that matches the benchmark set, testing must be done frequently throughout the software development lifecycle.

Quality control focuses on customer requirements and recommendations to validate a product. Therefore, the QC approach balances out compliance with demands.

Impact of software testing and QA on business

No matter how meticulous and precise we are with our job, we are bound to make mistakes. In this scenario, software testing and quality assurance are the knights in shining armor.

The only concern that you must have is to narrow down the possibility of getting into a bigger mess. Huge errors equal high cost, more time, and may also be dangerous. That is why it is prescribed to prepare a dynamic software testing and a quality assurance team.

Finding errors in the initial phase and rectifying them in advance will help your business in the long run.

When assuming at the initial stage that the final product might have its share of errors, gives us an upper hand to navigate the working approach.

By the means of combining above mentioned approaches, we stand a better chance of success in the market.
