What are the different integration testing methodologies?

There are several integration testing methodologies, including Big Bang, Top-Down, Bottom-Up, and Sandwich testing. Each has its own approach to integrating and testing components.

Can you explain the Big Bang integration testing methodology?

Sure! In Big Bang integration testing, all components are integrated at once, and then the entire system is tested as a whole. This method can be quick but may lead to challenges in identifying specific issues.

What are the pros and cons of Top-Down integration testing?

Top-Down integration testing starts with the top-level modules and progressively integrates lower-level modules. Pros include early detection of design flaws, while cons include the need for stubs for lower-level modules.

How does Bottom-Up integration testing work?

Bottom-Up integration testing begins with the lower-level modules and integrates them upwards. It allows for early testing of individual components but may delay the discovery of issues in higher-level modules.

What is Sandwich testing?

Sandwich testing is a combination of Top-Down and Bottom-Up approaches. It allows for parallel testing of both high and low-level modules, providing a balanced integration strategy.
