FeelUntil

FeelUntil is a concept or function often found in programming libraries designed for user interface automation or testing. Its primary purpose is to pause program execution until a specific condition is met or a certain element appears on the screen. This is crucial for ensuring that automated scripts interact with applications in a stable and reliable manner, as web pages or application interfaces can take time to load or update.

The core idea behind FeelUntil is to avoid hardcoded delays, which are often inefficient and brittle. Instead of waiting a fixed amount of time, FeelUntil actively monitors the application's state. When a predefined condition is satisfied, such as a button becoming visible, a text field being populated, or a specific element's attribute changing, the execution resumes. This dynamic waiting mechanism makes automated tests more robust to variations in network speed and application performance.

The implementation of FeelUntil typically involves a timeout parameter. This sets an upper limit on how long the program will wait for the condition to be met. If the condition is not satisfied within the specified timeout, an error or exception is usually raised, indicating a failure in the automation process. This prevents scripts from running indefinitely if an expected element or state never materializes.

FeelUntil contributes significantly to the reliability and maintainability of automated testing frameworks and UI interaction scripts. By ensuring that actions are performed only when the interface is ready, it reduces the chances of false positives or negatives in test results and makes the automation logic easier to understand and debug.
