What Does a Quality Assurance Engineer Do?

Quality assurance engineering mainly entails improving products and ensuring there are no defects in production. To properly check on the software development team’s work, you need to be proficient at testing on four different levels.

Performs Test Analysis

Test analysis is the process of checking the test requirements for completeness and consistency. In other words, you check what a product is designed to do and what optimal performance would look like. Usually, you gather the statistical requirements, set test objectives, and then determine which tests to use for a given product.

Performs Test Design

Once you decide which test to use, you then create the test and plan how each test will be executed. You should ensure all test documents and anything else you need for the tests are ready.

Performs Test Execution

In carrying out the planned tests, you need to keep detailed records of bugs and other issues found while developing the software. Also, you must outline the steps the software developer needs to take to fix the problems.

Performs Test Management

Finally, you are in charge of ensuring all deadlines are met, work schedules are followed, and tasks are assigned to the team. You must also keep track of what resources are needed for testing and communicate with the stakeholders throughout the process.

Essential Quality Assurance Engineer Skills

As part of your job, you must know how the software works, where it fails, and whether there are any glitches. You must be able to quickly determine the cause of an error and know how to fix it. To do these things effectively, you must possess the following technical skills.

Programming Languages

While a QA engineering job doesn’t involve developing code, you will test the code written by programmers and developers. You need to know at least one or two programming languages, preferably the one used in your line of work.

If you’re working in front end web development, for example, you’ll want to learn HTML, CSS, and JavaScript. If you get a QA job in the gaming industry, you should learn C++ and Java.

Test Case Development

You must be able to create test cases for different applications and plan how to execute those tests. A test case refers to a single requirement or group of requirements written by a QA engineer to show how an application functions.


While you don’t need to carry out the software tests by yourself, you need to be familiar with various automation tools such as CircleCI and also be able to create automation scripts. This can make your job as a quality assurance engineer much faster.

Bug Tracking

You must identify and record any bugs during testing and report them to the software development team for fixing. This is one of the most important skills that a QA engineer can have.
