Quality Assurance Engineer Technologies
and Coding Languages

Automation Testing Tools

Automation testing tools are used to streamline the quality assurance process. These tools rely on scripts and software to perform software testing with limited human interaction. QA engineers must understand how to use automation testing tools. This skill makes the software testing phase quicker and easier.

Functional Testing Tools

Functional testing is a form of black-box testing to ensure software functions as intended. QA engineers use functional testing tools by supplying the correct input data and verifying the output data against software standards. Functional testing tools help QA engineers confirm that software servers are functioning correctly.


Learning SQL is pivotal for QA engineers to update, verify, and delete test data in the software database. SQL is also a vital skill for QA engineers to recognize different databases, interpret complex queries, and connect database servers. Having SQL expertise makes verifying data easier and more accurate.

Agile Testing Tools
