While automated testing saves time on repetitive tasks, however, manual testing remains essential for QA engineers to understand user experience and identify unexpected bugs that scripts might miss.
Functional testing focuses on verifying that the software works as expected in terms of functionality. In most cases, it looks at whether specific actions produce the correct results. This includes testing user interface elements, database operations, and APIs.
Non-functional testing, however, evaluates the system's performance, reliability, and usability under various conditions. It includes tests like load testing, stress testing, and security testing. While functional testing verifies that the software does what it’s supposed to do, non-functional testing confirms it performs well, remains secure, and scales effectively under heavy loads.
A test plan is a strategic document that outlines the scope, approach, resources, and schedule for testing activities. A QA tester starts by reviewing your product's requirements and specifications. They do this to understand what needs to be tested. Based on their evaluation, the QA tester will then define the test objectives, scope, and key deliverables.
The test plan will include details such as the testing environment, the types of testing to be performed (e.g., unit testing, system testing), and the responsibilities of each team member. It also outlines the criteria for test completion and how defects will be tracked and resolved. The test plan acts as a roadmap for the entire testing process.
Whenever new features are added or bugs are fixed, there’s a risk that these changes might break other parts of the software. Regression testing confirms that new updates or changes in the software don’t negatively affect the existing functionality of the product.
Regression testing involves re-running previously executed tests to confirm that everything still works as expected. This type of testing is critical for maintaining the software’s stability over time. This is especially important in fast-paced development environments with frequent releases. Automated testing tools can run regression tests rather efficiently.
Test engineers use a variety of tools for bug tracking and test management. Popular bug-tracking tools include JIRA, Bugzilla, and Trello.
