When working with Selenium Webdriver in Node.js, one common task you might encounter is setting the value of an input field instead of using the `sendkeys` method. This can be particularly useful when you need to bypass certain front-end validation or simply want to directly populate an input field without simulating keystrokes.
To achieve this in Selenium Webdriver with Node.js, we can use the `executeScript` method provided by Webdriver to execute a custom JavaScript code snippet that directly sets the value of the input field.
Here's how you can accomplish this step by step:
1. Locate the Input Element: First, you need to identify the input element you want to set the value for using the standard techniques provided by Selenium Webdriver, such as locating it by id, class name, XPath, or other attributes.
2. Execute JavaScript to Set the Value: Once you have located the input element, you can proceed to execute a JavaScript snippet using the `executeScript` method. The JavaScript code will directly set the value of the input field without triggering any events.
const inputElement = await driver.findElement(By.id('your_input_id'));
await driver.executeScript("arguments[0].value = 'Your desired value';", inputElement);In the code snippet above, we first locate the input element by its id using `driver.findElement`. Then, we use `driver.executeScript` to set the `value` property of the input element directly to the desired value.
It's important to note that by setting the value using this approach, you are bypassing any input event listeners or validations that may be attached to the input field. Therefore, make sure this is the desired behavior for your test case.
3. Verify the Value is Set: After setting the value of the input field, you can perform any necessary verification checks to ensure that the value has been successfully populated. You can use assertions or other validation techniques provided by testing frameworks like Mocha, Chai, or Jest.
In conclusion, setting the value of an input field directly in Selenium Webdriver with Node.js can be a handy technique when you need to interact with input fields in a more controlled manner. By utilizing the `executeScript` method to execute custom JavaScript code, you can bypass event listeners and validations to efficiently set input values during your automated testing process.
