Which of the following are capabilities of Datadog browser tests?

The capability of Datadog browser tests being code-free signifies that users can create and manage tests without the need for programming skills. This is particularly beneficial for teams that may not have dedicated developers or those who want to conduct testing quickly without getting bogged down in code syntax and complexities. With a focus on user-friendliness, the capability allows testers to utilize a visual interface, making it more accessible and faster to set up tests compared to traditional coding methods.

In contrast, importing Selenium tests involves leveraging existing scripts written for that specific framework, which does require coding knowledge and may not be fully code-free. Running API tests within browser tests indicates integration and security checks that occur outside browser functionality, which might require additional configurations and is not purely focused on a code-free experience. Manual configuration denotes a requirement for hands-on adjustments or technical setup that contradicts the ease of the code-less approach championed by the correct answer.
