API testing and UI testing are two distinct challenges in software development, each with its own complexity and difficulties. While API tests may be easier to implement due to their simplicity and scalability, UI tests are harder to write and maintain because they deal with the high complexity of modern web applications. However, neither approach is inherently better than the other; what matters most is understanding the specific needs and goals of your product and testing strategy. Automated testing should focus on shipping great features without breaking things, keeping customers happy, and ensuring a stellar user experience. The key to effective testing lies in finding the right balance and choosing the tests that matter most, rather than chasing vanity numbers or trying to compare different approaches. Ultimately, both API and UI testing have their place in software development, and what's important is adopting a user and value-first approach to testing.
