QA establishes and maintains set requirements for developing or manufacturing reliable products.

A quality assurance system is meant to increase customer confidence and a company's credibility, while also improving work processes and efficiency, and it enables a company to better compete with others.

For example when you buy any fruit or vegetable, you can instantly evaluate its quality: the size and shape, ripeness, and the absence of visible bruising. But only as you take the first bite, will you be able to see if it's really that good. Even an extremely good-looking fruit or vegetable might taste sour or have a worm in it!

The same applies to almost any product, be it a physical object or a piece of software. A website you find on the Internet might seem fine at first, but as you scroll down, go to another page, or try to send a contact request, it can start showing some design flaws and errors or plain bugs.

This makes quality control so important in every field, where an end-user product is created and especially important in software development.

Even more critically, a sour fruit won’t cause as much damage as a self-driving car with poor quality autopilot software. A single error in an EHR system might put a patient’s life at risk, while an eCommerce website that has performance issues might cost the owner millions of dollars in revenue!

What is a QA engineer?

A Quality Assurance (QA) Engineer is responsible for ensuring that software meets quality standards and is free of bugs before its release to the public.

They work closely with the development team to ensure that the software is functional, reliable and meets the requirements set by the stakeholders.

To become a QA Engineer, typically you need a degree in computer science or a related field. Experience with software development and testing, as well as knowledge of programming languages and test automation tools, are also important. Some companies also require certifications in software testing or quality management.

What does a QA engineer do?


QA Engineers are responsible for ensuring that software meets quality standards and is free of bugs by creating test cases, executing manual and automated tests, and analyzing test results. They also communicate with stakeholders to understand requirements and work closely with development and testing teams to ensure timely delivery of projects. Additionally, they may suggest changes to enhance product features and stay up-to-date with industry developments and regulations.

Below are some duties that a QA engineer is likely to perform on a weekly or even daily basis:

  • Create standards and procedures for developers to follow
  • Execute both manual and automated test scripts
  • Code and implement automated tests
  • Communicate with stakeholders to understand and clarify software requirements
  • Analyze test results to predict user behavior, identify bugs and suggest solutions to minimize problems
  • Work closely with product development and testing teams to ensure timely delivery of the project
  • Keep track of quality metrics
  • Verify that the final product meets the requirement
  • Analyze product features and suggest changes to enhance them to make them more efficient and user friendly
  • Stay up-to-date with the latest industry developments, standards and regulations

Why are QA Engineers important? What are the emerging challenges?

As a part of technological progress, testing is continually evolving to meet ever-changing business needs as it adopts new tools that allow the tester to push the boundaries of quality assurance. New subjects expected to affect software testing in the near future are security, artificial intelligence, and big data.


The World Quality Report survey shows that security is one of the most important elements of an IT strategy. Input from security is vital to protecting the business. Security vulnerabilities can seriously tarnish brand reputation. For those reasons, test environments and test data are considered the main challenges in QA testing today. The four main focus areas in security testing include:

  1. Network security
  2. System software security
  3. Client-side application security
  4. Server-side application security

It is highly recommended that security testing is included as part of the standard software development process.

Artificial Intelligence

The challenges of testing are increasing and their solutions have an unlimited number of situations requiring artificial intelligence to test them thoroughly. Different implementations of AI using machine learning-based algorithms will soon become embedded in applications to perform tasks once reserved for humans. Although test automation solutions in the intelligence area are not well-established yet, the shift towards more intelligence in testing is inevitable. 

A Boston-based startup mabl already simplify functional testing by combining it with machine learning. With mabl there is no need to write extensive tests by hand. Instead, you show the application the workflow you want to test and the service performs those tests. Mabl can even automatically adapt to small user interface changes and alert developers to any visual changes, JavaScript errors, broken links, and increased load times.

Big Data

Currently, the two major concerns regarding test data management are data compliance and big data.

First, with many onerous protection laws arriving on the scene, simply copying real-world data presents a risk of violating them. For example, the EU’s General Data Protection Regulation (GDPR) became law in May 2018 for all companies operating in the EU. Given the threat of significant fines, data compliance concerns are on the front burner of most IT departments today. Second, managing huge volumes of data that are constantly uploaded on various platforms demands a unique approach for testing as traditional techniques can no longer cope.

Big data testing is aimed at checking the quality of data and verifying data processing. Data quality check involves various characteristics like conformity, accuracy, duplication, consistency, validity, data completeness, etc. Data processing verification comprises performance and functional testing. Big data testing demands a high level of testing skills as the processing is very fast.

In conclusion, despite a widespread misbelief that a tester’s only task is to find bugs, testing and QA have a greater impact on the final product success.

Having a deep understanding of the client’s business and the product itself, QA engineers add value to the software and ensure its excellent quality. Moreover, applying their extensive knowledge of the product, testers can bring value to the customer through additional services, like tips, guidelines, and product use manuals. This results in reduced cost of ownership and improved business efficiency.

How is automated QA different from manual QA?


Automated and manual quality assurance are both methods used to ensure the quality of a product or service.

Automated quality assurance uses software tools and scripts to test and verify that the product or service meets the specified requirements and works as intended. This method is efficient and can be run frequently and quickly, but it may not be able to detect all bugs or issues.

Manual quality assurance, on the other hand, involves manual testing by a human tester to verify that the product or service meets the specified requirements and works as intended. This method allows for more thorough testing and can detect issues that automated testing may miss, but it can be time-consuming and expensive.

Some more elements to consider:

Manual Testing

  • Human errors can reduce the accuracy, making this method less reliable
  • Manual testing requires a dedicated team of individuals, this makes the process time consuming
  • Need to invest in finding the right team
  • Better suited for a project where test cases are run once or twice and there is no need for repetition frequently
  • Human observation can help evaluate the user-friendliness quotient and help in achieving a better experience for the end user

Automated Testing

  • Testing performed using tools and scripts makes this method more reliable
  • It is relatively faster as the testing is done using software tools, making it better than a manual process
  • You need to invest in acquiring testing tools
  • It is a practical choice when the test cases need to run regularly over a significant amount of time
  • User-friendliness and end-user experience cannot be defined due to the lack of human observation
As we can see both manual and automated QA methods have their own advantages and disadvantages, and organizations often use a combination of both automated and manual testing to ensure the highest level of quality assurance.

What technologies does a QA engineer use?


QA (Quality Assurance) engineers use a variety of technologies to ensure the quality of a product or service. Some of the common technologies used by QA engineers include:
