Some different types of integration testing are big-bang, mixed (sandwich), risky-hardest, [[top-down and bottom-up design|top-down, and bottom-up]]. Other Integration Patterns<ref>Binder, Robert V.: ''Testing Object-Oriented Systems: Models, Patterns, and Tools''. Addison Wesley 1999. {{ISBN|0-201-80938-9}}</ref> are: collaboration integration, backbone integration, layer integration, client-server integration, distributed services integration and high-frequency integration.
In big-bang testing, most of the developed modules are coupled together to form a complete software system or major part of the system and then used for integration testing. This method is very effective for saving time in the integration testing process {{cn|date=May 2024}}. However, if the test cases and their results are not recorded properly, the entire integration process will be more complicated and may prevent the testing team from achieving the goal of integration testing.
In bottom-up testing, the lowest level components are tested first, and are then used to facilitate the testing of higher level components. The process is repeated until the component at the top of the hierarchy is tested. All the bottom or low-level modules, procedures or functions are integrated and then tested. After the integration testing of lower level integrated modules, the next level of modules will be formed and can be used for integration testing. This approach is helpful only when all or most of the modules of the same development level are ready. This method also helps to determine the levels of software developed and makes it easier to report testing progress in the form of a percentage.
