eventualWait
eventualWait is a concept or mechanism used in software development, particularly in asynchronous programming and testing, to handle situations where a certain condition is expected to become true after some delay. It is not a specific, universally defined programming language keyword or function, but rather a pattern or a utility function implemented in various libraries and frameworks. The core idea behind eventualWait is to repeatedly check for a specific condition until it is met, or until a predefined timeout occurs. This is especially useful when dealing with operations that do not complete instantaneously, such as network requests, database updates, or UI rendering. Instead of blocking the main thread while waiting, eventualWait allows the program to continue executing other tasks and periodically polls the state of the condition. If the condition is met within the allocated time, the waiting process terminates successfully. If the timeout is reached before the condition is satisfied, it typically results in an error or a failure indication. This pattern is common in automated testing frameworks, where tests often need to wait for an element to appear on a web page or for a background process to finish before asserting its state. The implementation details of eventualWait can vary, often involving parameters for the polling interval and the maximum waiting time.
