The document discusses the differences between functional testing and end-to-end testing, and explains that while they are related, they are not the same. It notes that functional testing ensures each application function works as specified, while end-to-end testing checks the full application flow. The document also states that functional testing is a component of system testing and includes performance testing, and that while manual testing is still used, functional testing should be automated as much as possible.

• Functional Testing—makes sure that
each function of an application is in
conformance with specified
requirements.
• End-to-End Testing—used to test
whether the flow of an application is
performing from start to finish.
• Functional testing before end-to-end
testing

• Functional Testing is a component of system testing.
• System testing is a black box test to verify:
• End-to-end testing scenarios
• User’s experience with an application
• Fully integrated applications

• Functional testing and performance testing are in two different categories
• Functional Testing
• Non-Functional Testing
• Performance Testing
• Security Testing
• Reliability Testing

11. All functional testing should be automated.

13. All functional testing should be automated.
• As long as humans are interacting with
applications, manual testing will always be around
• Use manual testing:
• Exploratory testing
• Usability testing
• Ad-hoc testing
• Use manual testing to mimic real world user
interactions
• Manual testing can be useful to look at an
improved customer experience
