User testing is a vital aspect of user research, essential for uncovering insights at various stages of the design process. From cost-effective early-stage methods like guerilla testing with paper mockups to more sophisticated techniques like eye-tracking, different tests offer varying insights.

While some methods require minimal resources and can be employed quickly, others necessitate specialized equipment, high-fidelity prototypes, or even dedicated user research laboratories.

Regardless of the technique, the fundamental goal of user testing remains the same — to gather valuable feedback. This feedback helps designers identify and address potential issues as early in the design process as possible, ensuring a more user-centered and effective final product.
