Adaptive Server Enterprise 11.5 Summary of Testing Techniques

• Production load capture

Table 7-1: Summary of testing techniques

Technique Description Advantages Disadvantages

Ad hoc

testing

Manually walk

through important

application processes,

screens, and reports.

• Easy to implement.

• Tests front-end

applications and

back-end servers.

• For complex applications, code

coverage is too small.

• Difﬁcult to distinguish front-end

and back-end bottlenecks if

response time is a determining

factor.

• Impossible to obtain production

multiuser load, which misses

concurrency and capacity issues

altogether.

Manual

performance

scripts and

cases

Specify input and

compare with known

outputs.

• Easy to implement.

• Common basis for

regression test

suites.

• Only tests back- end server.

• Back-end focus may help locate the

cause of a problem.

• Impossible to obtain production

multiuser load, which misses

concurrency and capacity issues

altogether.

• No ad hoc query testing.

• Depends on strong analysis of

process or transaction proﬁles.

Keystroke

capture

Record and replay

keystrokes and mouse

clicks into an

application.

• Tests front-end

applications and

back-end servers.

• Tool may include

powerful language

and looping

capabilities to

manipulate inputs

for multiuser

concurrency and

capacity testing

• Heavy processing requirements.

May require additional hardware.

• May increase development time for

creating multiuser test simulations,

and add time for debugging test

harness.

• Depends on strong analysis of

process or transaction proﬁles.
