After all units have been tested in isolation and verified working correctly, the next of testing begins: Integration Testing.

Two Possible Processes

Two modules integrated and tested

Another module added to them and tested

Continues until all units are added

OR

Units grouped by functional area

Tested together as assemblies

Top Down Testing

Top layers tested

Lower layer integrated and tested

Process continues until full integration

Bottom Up Testing

Lowest levels validated

Higher level component integrated and tested

Process continues until full integration

By testing the units in aggregate, it’s easier to identify the source of the issues found.

 

Defects generally found in this phase

Inter-process communication

Parameter issues

Data issues

Testers involved in this phase should have a solid background in integration testing techniques.
