How to Check an Element's Value in Playwright

With the release of Playwright version 1.20, the framework introduced the toHaveValue() assertion, enhancing the process of verifying the value held by elements such as input fields:

await expect(page.locator('input#name-input')).toHaveValue('John Doe');

This assertion also supports the use of regular expressions for more dynamic checks:

await expect(page.locator('input#name-input')).toHaveValue(/\w+/);

When dealing with select elements that permit multiple selections, the toHaveValues() assertion comes into play, allowing verification against multiple expected values:

await expect(page.locator('select')).toHaveValues([/Red/, /Green/]);

If your intention is merely to retrieve an element's value without making an assertion, the inputValue() method is applicable for <input>, <textarea>, and <select> elements:

const value = page.locator('input#name-input').inputValue();

For retrieving text from other element types, innerText() is the method of choice, while toHaveText() serves to assert the text content:

const value = await page.getByRole('heading').innerText();

await expect(page.getByRole('heading')).toHaveText('A heading');
