4. Element Locators: Finding What You Need

• Types of Locators: Exploring various locator strategies (ID, Name, XPath, CSS Selectors, etc.).
• Best Locator Practices: Choosing the most reliable and maintainable locators.
• Locator Debugging: Techniques for identifying and resolving locator issues.
• Reliable vs. Unreliable Locators: Understanding the stability of different locator strategies.
• Element Lists: Locating elements within a list or table.
• Locating Within Elements: Finding elements nested within other elements.
