How to solve: Write a Robust Selenium Explicit Wait?

Question

Accepted Answer

Using implicit sleep timers like `time.sleep(5)` slows down testing suites.
To optimize synchronization:
1. Define a wait utility using `WebDriverWait(driver, 10)`.
2. Use expected conditions: `EC.visibility_of_element_located((By.CLASS_NAME, "result-container"))`.
3. The driver will poll the DOM dynamically and proceed the microsecond the element renders, up to a maximum timeout of 10s.
