A team is developing a critical financial application with strict regulatory requirements. They have a limited budget and a tight release schedule. They must ensure high confidence in the correctness of transactions. The team is considering whether to invest in more unit tests or more end-to-end tests. What is the most balanced approach?

Use manual testing for regulatory scenarios and automate only unit tests

Invest heavily in end-to-end tests to cover all regulatory requirements

Focus solely on unit tests since they are the most reliable and cost-effective

Prioritize unit tests for the transaction logic and add a small set of end-to-end tests for critical regulatory scenarios

What is the primary purpose of automating acceptance tests?

To verify that the system satisfies business requirements and is ready for delivery

To test the performance and load-handling capacity of the system

To check that individual functions return correct values

To verify that modules communicate correctly with each other

A team is automating tests for a payment processing module. They want to verify that the module correctly calculates discounts and taxes, and that it communicates properly with the inventory system. Which combination of automation levels is most appropriate?

Integration tests that test the payment module with the inventory system only

System tests that simulate the entire payment flow from the user interface

Acceptance tests that validate the business rules with real user scenarios

Unit tests for the calculation logic and integration tests for the inventory interface

A team is automating tests for a mobile application that relies heavily on device-specific features (e.g., camera, GPS). They have a limited device lab and need to balance coverage with cost. What is the most effective automation strategy?

Automate unit and integration tests for business logic, and use a small set of device-specific tests on real devices for critical features

Automate all tests on real devices to ensure maximum accuracy

Skip automation for device-specific features and test them manually

Automate all tests on emulators to save cost

In a project with a very tight schedule and high risk of regression in core business logic, which automation level should be prioritized?

Integration-level automation, because it checks module interactions

System-level automation, because it tests the entire application end-to-end

Unit-level automation, because it is fast and provides quick feedback on regressions

Acceptance-level automation, because it validates business requirements
