condition-based-waiting

Condition polling replaces fixed delays by repeatedly checking for a specific state change, such as an element becoming visible or an item count updating, ensuring tests proceed only when the condition is met.

You replace setTimeout or sleep by implementing a polling mechanism with configurable timeouts that repeatedly evaluates a condition, such as cart item count exceeding zero, and proceeds only when that condition is satisfied.

The best approach is condition polling, which evaluates desired states repeatedly within a configurable timeout window and proceeds only upon success, avoiding arbitrary delays that cause inconsistent pass/fail behavior.

Yes, this approach requires a polling mechanism with configurable timeouts to define the maximum wait duration and generates clear error reporting when conditions remain unmet, ensuring robust test failure visibility.

Use condition polling in scenarios involving race conditions, timing dependencies, or inconsistent pass/fail behavior, where server load or network latency makes fixed delays unreliable for waiting on state changes.

Tests fail intermittently because arbitrary timeouts guess timing rather than verifying state. Condition polling eliminates this by waiting for actual state changes, ensuring tests proceed only when conditions are truly met.
