Answer 9

involves testing the individual modules of code or classes with comprehensive test data

Question 10

Component Testing

Answer 10

This is testing a collation of dependant components with the usual wide range of test data to ensure robustness and reliability. This may also flag up parameter passing issues.

Question 11

Beta Testing

Answer 11

involves delivering a system to a number of potential customers . They report problems to the system developers. This exposes the product to real use and detects errors that may not have been anticipated by the system builders

Question 12

Acceptance Testing

Answer 12

The final stage of testing when the system is complete . Will use real data supplied by the customer . The aim is to ‘prove’ the functionality, reliability and robustness of the system
