Have you ever wondered how software developers ensure their products are bug-free and deliver a seamless user experience? That’s where Quality Assurance (QA) Engineers come in. QA Engineers are the backbone of software development, ensuring that everything works as intended. In this guide, we’ll explore the path to becoming a QA Engineer, covering everything from essential skills to career advancement.
Who is a Quality Assurance (QA) Engineer?
A QA Engineer is a professional responsible for testing software applications to ensure they are free of bugs and meet user expectations. They play a crucial role in delivering high-quality software by identifying issues before the product reaches users.
