Integration Testing Services

A typical project comprises multiple modules coded by a team of programmers. Even with fastidious unit testing, miscommunication between team members or changes in requirements can cause issues when individual modules are put together.

By pinpointing these issues early, our integration testing services enable clients to save time and money on projects of various size and complexity.

Leverage our know-how to examine interfaces and data flow between components, track down functional, performance, and reliability defects early on, and respond to them before they turn into serious problems.

Our Strategies

When working on your project, our QA experts take into account scope complexity, time constraints, and other factors to work out the best-fitting integration testing strategy.

Incremental Integration Testing

We start with testing the communication between a few logically related components and add new ones after each test is success­fully completed. This approach has multiple advantages:

  • The team can choose between top-down, bottom-up, and other methods for adding new modules.
  • Easier bug localization in large, complex systems.
  • It’s possible to prioritize certain components when necessary.
  • Testing can start before all components are complete.

Big Bang Integration Testing

When the development of all components is complete, we integrate them en masse and test the communication in the resulting system. The approach makes it possible to:

  • Save testing time on smaller projects with a relatively low number of modules.
  • Uncover more errors early in the testing process.
  • Save resources, as there’s usually no need for mock programs like drivers and stubs.
