Steps
Use `Retry.WhileFalse(() => element.IsEnabled, timeout: TimeSpan.FromSeconds(5))` (namespace `FlaUI.Core.Tools`) to poll a boolean condition instead of a fixed sleep
Use `Retry.WhileException(() => element.Click())` to retry an action that may throw while the UI is still settling, rather than catching and sleeping manually
Use `Retry.WhileNull(() => window.FindFirstDescendant(cf => cf.ByAutomationId("target")))` to poll for an element's appearance before interacting with it
Tune `timeout` and `interval` per call (defaults are 1000ms timeout / 100ms interval) rather than relying on the library-wide default for slow operations
Set `throwOnTimeout: true` when you want a hard failure instead of silently returning the last/default value after the retry window elapses
Check `RetryResult<T>.Success` on the returned result when `throwOnTimeout` is false, since a timed-out retry still returns a value instead of throwing
Known gotchas
Default timeout/interval (1000ms/100ms) is tuned for fast local UI; slow CI machines or heavy apps commonly need explicit longer `timeout` values or you'll get spurious "not found" failures
`Retry.While` and its overloads have many optional parameters (`ignoreException`, `lastValueOnTimeout`, `defaultOnTimeout`) — pin the ones you rely on explicitly rather than trusting positional defaults, since the wrong combination silently changes failure behavior instead of erroring
