System tests are often performed by independent teams.

Functional testing is used more than structural testing.

Faults found during system tests can be very expensive to fix.

End-users should be involved in system tests.

Incidents should always be fixed.

An incident occurs when expected and actual results differ.

Incidents can be analysed to assist in test process improvement.

An incident can be raised against documentation.

time runs out.

the required level of confidence has been achieved.

no more faults are found.

the users won’t find any serious faults.

Incident resolution is the responsibility of the author of the software under test.

Incidents may be raised against user requirements.

Incidents require investigation and/or correction.

Incidents are raised when expected and actual results differ.

syntax testing

equivalence partitioning

stress testing

modified condition/decision coverage

In a system two different failures may have different severities.

A system is necessarily more reliable after debugging for the removal of a fault.

A fault need not affect the reliability of a system.

Undetected errors may lead to faults and eventually to incorrect behaviour.

They are used to support multi-user testing.

They are used to capture and animate user requirements.

They are the most frequently purchased types of CAST tool.

They capture aspects of user behaviour.

They are cheapest to find in the early development phases and the most expensive to fix in the latest test phases.

They are easiest to find during system testing but the most expensive to fix then.

Faults are cheapest to find in the early development phases but the most expensive to fix then.

Although faults are most expensive to find during early development phases, they are cheapest to fix then.

To find faults in the software.

To assess whether the software is ready for release.

To demonstrate that the software doesn’t work.

To prove that the software is correct.
