This provides valuable data on visual attention patterns, revealing areas that attract or repel users' gaze. It's particularly useful for evaluating website design and user interface elements.

5. Heuristic Evaluation: Experts in usability principles evaluate the software based on established guidelines and best practices (heuristics). This approach can quickly identify potential usability problems without involving actual users, though it's less effective at identifying issues that only real users would encounter.

6. Cognitive Walkthrough: This technique focuses on understanding the cognitive processes involved in using the software. Testers step through a specific task, considering what the user would be thinking at each step and identifying potential points of confusion or difficulty.

7. User Surveys and Questionnaires: Gathering feedback through surveys and questionnaires is a cost-effective method to collect broader user perspectives and opinions on various aspects of the software, including satisfaction, ease of use, and overall experience.

Choosing the right technique depends on the specific goals, budget, and timeline of the testing process. Often, a combination of techniques is employed for a comprehensive evaluation.

Simple Answer:

Common software user testing techniques include usability testing (watching users interact), A/B testing (comparing versions), beta testing (releasing to a wider group), eye-tracking (measuring visual focus), and heuristic evaluation (expert review).

Reddit Style Answer:

Dude, so you wanna test your software? Here's the lowdown. Usability testing is like watching people try it out – hilarious to see them struggle sometimes! A/B testing is all about comparing two versions to see which one's better (data-driven, yo!). Beta testing is letting a bunch of random peeps loose on it before launch. Eye-tracking is super cool – you can see exactly where their eyes go on the screen. And heuristic evaluation is when the experts get to nitpick – basically, professional critics for your app.
