To extract a locator for an element in Chrome's Inspect Elements, you can follow these steps:
Right click on the element you want to locate (in this case, the Login button) and select "Inspect" from the context menu. This will open the Chrome DevTools panel and highlight the corresponding HTML code.
In the DevTools panel, locate the highlighted HTML code that represents the Login button. It might be a button, input, or any other relevant HTML tag.
Look for unique attributes of the element that can be used as locators. Commonly used attributes include id, class, name, data-* attributes etc.
Reference :
Using id attribute: If the element has a unique id attribute, you can use it as a locator. For example: By.id("loginButton").
Using class attribute: If the element has a unique class, you can use it as a locator. For example: By.className("login-button").
Using other attributes: If there are no unique id or class attributes, you can use other attributes like name, data-*, or cssSelector. For example: By.cssSelector("button[data-testid='loginButton']").
