Automation is required in testing to increase efficiency, reduce human error, save time, and improve test coverage.

• Automation helps in executing repetitive test cases quickly and accurately.

• It allows for running tests on multiple configurations and environments simultaneously.

• Automation can be used for regression testing to ensure that new code changes do not break existing functionality.

• It helps in increasing test coverage by running a large number of test cases that would b...read more

To test an API without a real entity, use mock data or create dummy data for testing purposes.

• Create mock data that simulates the expected behavior of the real entity

• Use tools like Postman or cURL to send requests to the API using the mock data

• Verify that the API responds correctly to the requests and returns the expected results

• Test different scenarios and edge cases to ensure the API handles them properly

• Monitor the API's performance and check for any errors or inconsistenc...read more

• Class name - class attribute value of an element

• Name - name attribute value of an element

• Tag name - HTML tag of an element

• Link text - text of a link element

• Partial link text - partial text of a link element

• XPath - XML path expression to locate elements

Regression testing is testing the entire application after changes, while retesting is testing a specific bug fix.

• Regression testing is done to ensure that new code changes do not affect existing functionality.

• Retesting is done to verify that a specific bug or issue has been fixed.

• Regression testing involves testing the entire application, while retesting focuses on a specific area.

• Examples: After adding a new feature, regression testing is done to check if existing features ...read more

CSS selector is the fastest locator.

• CSS selector is faster than XPath

• ID and class selectors are faster than tag and attribute selectors

• Avoid using complex CSS selectors for better performance

Absolute XPath specifies the location of an element from the root of the document, while relative XPath specifies the location of an element relative to another element.

• Absolute XPath starts with a single forward slash (/) and specifies the complete path from the root element to the desired element.

• Relative XPath does not start with a forward slash and specifies the path from the current node to the desired element.

• Absolute XPath is more brittle as any changes in the structur...read more
