Handling Asynchronous Operations in WebDriverIO with JavaScript

When working with WebDriverIO and JavaScript for test automation, it is essential to handle asynchronous operations effectively. Asynchronous operations, such as waiting for elements to load or resolving promises, can cause timing issues if not handled properly. In this article, we will explore how to handle asynchronous operations in WebDriverIO to ensure stable and reliable test execution.

Using the waitUntil() Method

await browser.url("https://en.wikipedia.org/wiki/Main_Page");
await browser.waitUntil(async () => {
  const element = await $('YOUR_LOCATOR');
  return await element.isDisplayed();
}, { timeout: 5000, timeoutMsg: 'Element not displayed within 5 seconds' });

The waitUntil() method in WebDriverIO allows us to wait for a certain condition to be fulfilled before proceeding with the test. It takes a callback function that returns a boolean indicating whether the condition is met or not. In this case, we are waiting for an element specified by the locator to be displayed.

Here is an example test that uses the above code snippet.

By utilizing the waitUntil() method, you can ensure that your tests wait for necessary conditions to be fulfilled, allowing for smooth and synchronized test execution.
