TestDriver provides custom error classes with rich debugging information. These are exported from the SDK and can be used for instanceof checks in your tests.
import TestDriver, { ElementNotFoundError, AIError } from 'testdriverai';
Thrown when find() cannot locate an element on screen, or when calling click()/hover() on an unfound element.
try {
await testdriver.find('nonexistent button').click();
} catch (error) {
if (error instanceof ElementNotFoundError) {
console.log(error.description); // "nonexistent button"
console.log(error.screenshotPath); // path to debug screenshot
console.log(error.pixelDiffPath); // path to pixel diff image
}
}
