Final answer:
Wireframes should test interaction, not color schemes or code syntax.
Step-by-step explanation:
Wireframes are visual representations of a website or application's layout and design. They are created in the initial stages of the design process to outline the structure and functionality of the interface. One key component of wireframes is testing interaction. This involves simulating how users will interact with the interface and ensuring that it is intuitive and user-friendly.
Color schemes, on the other hand, are not a key component of wireframes. While color can be used in wireframes to distinguish different elements or highlight important information, it is not the primary focus at this stage of the design process.
Code syntax is also not a key component of wireframes. Wireframes are typically created using specialized wireframing tools or graphic design software, and do not involve programming or writing code.
