Final answer:
Integration testing verifies that separate systems can work together.
Step-by-step explanation:
The type of testing that verifies that separate systems can work together is called integration testing. Integration testing is focused on testing the interactions and interfaces between different components or systems to ensure that they function correctly when integrated together.
For example, in software development, integration testing is used to test the interoperability of different software modules or components. It helps identify any issues or bugs that may arise when multiple systems are combined.
Integration testing can be done using various techniques, such as top-down integration testing, bottom-up integration testing, or sandwich integration testing. These techniques ensure that all the individual components function properly when integrated into a larger system.
