A team is testing an application that depends on a legacy mainframe system. The mainframe is slow and often unavailable during peak hours. What is the best way to handle this dependency in end-to-end testing?

Increase the timeout values in the tests to handle the mainframe's slowness.

Test only during off-peak hours when the mainframe is available.

Use a simulator for the mainframe in most tests, and run a few tests against the real mainframe when possible.

Remove the mainframe from the test scope.

What is a key characteristic of a well-designed end-to-end test scenario?

It tests a single component in isolation

It covers a complete business process across multiple components and interfaces

It focuses only on the user interface

It is independent of any business process

An end-to-end test for a flight booking system passed, but the business owner reports that the booking confirmation shows the wrong departure time. The test data used a specific flight with a known departure time. What is the most likely reason the test did not catch this defect?

The test was not run against the real booking system.

The test did not verify the departure time in the confirmation output.

The test environment was not synchronized with production.

Which statement best describes what end-to-end testing validates?

The security of the system against external attacks

The performance of individual database queries

The complete business process from start to finish, including all integrated systems and interfaces

The interaction between two adjacent modules in a system

An end-to-end test for an online payment system depends on an external payment gateway that is only available during business hours. The team needs to run tests at any time. What is the best mitigation strategy?

Extend the business hours of the payment gateway by contacting the provider.

Skip tests that depend on the payment gateway.

Run tests only during business hours when the gateway is available.

Use a virtualized or simulated version of the payment gateway for most tests, and run a smaller set against the real gateway when available.
