Integration Testing
Integration testing is a crucial phase in software development where software modules are logically integrated and tested together. Since most software projects involve multiple modules created by various programmers, this testing level is essential to uncover errors in how these modules interact once integrated. It focuses on verifying data communication between modules, often referred to as string testing or thread testing.
At TechCryptors, we employ various strategies to execute integration testing:
- Big Bang Approach: Testing all modules together at once after integration.
- Incremental Approach: Integrating and testing modules in steps, which is further divided into:
- Top-Down Approach: Testing starts from the top-level modules and progresses downwards.
- Bottom-Up Approach: Testing begins with lower-level modules and proceeds upwards.
- Sandwich Approach: Combining top-down and bottom-up approaches for a comprehensive integration test.
We use a range of tools for integration testing, including:
- Rational Integration Tester: For automated integration testing.
- Protractor: For end-to-end testing, especially in Angular applications.
- Steam: For testing in continuous integration environments.
- TESSY: For testing embedded systems.
These strategies and tools ensure that the integration of software modules is seamless and that any issues are identified and resolved efficiently, leading to robust and reliable software applications.
