In Protractor, you can get data from promises using the then method or by using async/await syntax. Protractor is built on top of WebDriverJS, which returns promises for most of its actions and interactions with the browser.

Here's how you can get data from promises in Protractor:

  1. Using then method: The then method is used to handle the resolved value of a promise. It takes a callback function as an argument, which will be executed when the promise is resolved.

    Example:

    javascript
    const myElement = element(by.css('.my-element-class')); myElement.getText().then(function(text) { console.log('Text from element:', text); });
  2. Using async/await: async/await is a more convenient way to work with promises and make the code look more synchronous. You can use await to wait for a promise to resolve and get its result directly.

    Example:

    javascript
    const myElement = element(by.css('.my-element-class')); async function getElementText() { const text = await myElement.getText(); console.log('Text from element:', text); } getElementText();

Both methods will work to retrieve data from promises in Protractor, but keep in mind that when using async/await, the function containing await must be marked as async. Also, ensure that you have enabled the SELENIUM_PROMISE_MANAGER in your Protractor configuration to use the WebDriver control flow.

Additionally, you can chain multiple promises using then, or use await inside async functions to handle asynchronous operations more elegantly.

Remember that Protractor is primarily designed for testing AngularJS and Angular applications, so it is best suited for handling Angular-specific asynchronous operations. If you're testing non-Angular applications or websites, you might need to handle asynchronous operations differently, such as using explicit waits or other techniques.
