What is a QA tester? – Genislab Technologies

A Quality Assurance (QA) tester is a professional responsible for testing a software application’s quality. They ensure that the software meets the end user’s requirements and is free of any defects. QA testers use various tools and techniques to test the software, including manual testing, automated testing, or a combination of both.

A QA tester is a quality assurance specialist who tests software to ensure it meets customer expectations and is free of defects. They work closely with software developers to investigate and resolve issues. QA testers typically have a background in computer science or engineering.

Origins of QA tester role

The QA tester role originated in the 1950s with the advent of computer technology in the workplace. Companies began to recognize the need for employees who could evaluate computer programs and hardware for accuracy and effectiveness.

The first QA testers began working closely with computer engineers to learn the programming language, Using hand-drawn flowcharts, they created detailed test plans and organized lists of test cases.

The QA testers would report their findings and lists of test cases after they complete the test. Once the tests were completed, the QA testers would report their findings to programmers. Together, they would analyze the results and identify bugs and critical errors in the software.

Over time, the QA testers developed the skills to perform some of the basic debugging functions themselves. Over the next decades, the QA testing role expanded to include black box testing and other duties.

What do they do?

A QA tester is a professional who evaluates software to ensure that it meets quality standards. They are also involved in writing and executing test plans and test cases.

Automated testing

Automated testing is the use of software to perform the test execution. This allows for many tests to be run in a short amount of time. While this does remove some of the human error from the testing process, it is important to note that automated testing only confirms that the software works according to its internal logic. It does not assess whether the software meets the needs of its users.

Manual testing

Manual testing is the purest form of testing and involves using the software to test its functionality.

This is often the first step in the testing process as it allows testers to discover and report critical bugs. While manual testing is time-consuming, it is highly effective at finding critical bugs and confirming that the software meets the needs of its users.

Black-box testing

Black-box testing refers to the test environment being a black box. The tester has access to an external interface of the application under test and can execute their tests based on their knowledge of the system,

This is the most common testing method and involves both execution time and complexities.

White-box testing

White-box testing refers to a white-box test environment, where the tester has direct knowledge of the application source code.

Using this knowledge, the tester can strategize and effectively test the system.

This highly effective testing method involves both execution time and complexity.

Regression testing

Regression testing refers to the process of re-running previously completed tests to ensure that recently changed code has not altered the functionality of the application.

Most software aims to ensure that all tests are run in each regression cycle to identify any bugs as soon as possible.

What is required to be a QA tester?

QA testers need to have strong attention to detail, excellent communication skills, and experience with various testing tools and methodologies.

To be successful, a QA tester must be able to work collaboratively with developers and other stakeholders to identify and resolve any issues.

Attention to the details

The ability to look at all the details ensures overall productivity, performance, efficiency, and client satisfaction. This ability can be applied wherever you see an opportunity to implement a higher level of task performance.


You can become more productive and efficient in the workplace by practicing your organizational skills. While some ways can be learned, others need to be taught.

If you neglect the development in this area, you may have trouble getting things done.

Skills of listening

QA testers need to be diligent as to how they listen to and follow instructions given by supervisors, as well as how they communicate with their QA peers.

Communication skills

It is common for quality assurance testers to communicate with and collaborate with other team members. This communication may be about issues and errors with your product, so the ability to discuss it tactically is a must.

Solving problems

Quality assurance (QA) testers play a key role in identifying errors at work, QA testers often use repetitive, computer-based tasks to identify subtle problems in their work.

Additionally, good thinking and reasoning skills are necessary for these positions.

Showing cause and effect

An important type of logical thought that is part of the Logical Thinking module is Deductive Reasoning.

In Deductive reasoning, we are using statements or conclusions to lead to one or more particular outcomes. We find this in if-then statements.

How to organize your time

Depending on varying wildfire-related issues, the time required by a quality assurance tester to complete their duties and tasks can often vary greatly. They are also often required to thrive under strict and potentially unexpectedly tight deadlines.

Being able to allocate their time efficiently to perform their duties and meet their deadlines is vital to a QA tester’s ability to execute their duties and responsibilities.

What education is required?

QA testers typically have a bachelor’s degree in computer science or a related field. They must have strong analytical and problem-solving skills and be able to work independently. Although the position does not require it, many QA testers also have a certification in software testing, such as a CASA or CSTA certification.

QA tester salary

How well you do in your job and your experience level is the two most important factors that influence your salary as a quality assurance tester. Other factors that may be involved are the business’s location, the industry it is in, and the demand for that position.

The government assessed that the national average wage for quality assurance testers is $53,688 per year or $27.73 per hour. This will likely vary depending on your location, experience, and working style and may fluctuate.


A QA tester’s job is important because they play a vital role in ensuring that the software meets the quality standards set by the client or company. A career as a QA tester can be both challenging and rewarding, and it offers opportunities for career growth.
