How it works
Use this as part of your automated test flow. Wait for the element or state you are acting on to be ready rather than assuming it, and pair the call with an assertion so a failure is explicit rather than a silent pass. Small, focused snippets like this are easier to debug and reuse than long, tangled test steps.
When to use it
Reach for this when you need Run a query and assert in Java. Keep your locators stable and your waits explicit, and confirm the snippet against your installed version — automation APIs shift between major releases, so the exact signature can change over time. When in doubt, check the official documentation for the current form.
