9.6 DEC Performance and Coverage Analyzer

• Ada multitasking data—Many types of multitasking data can be gathered to

determine which tasks consume the most resources.

• Exact execution counts—Information about the exact number of times

speciﬁed program locations are executed helps illuminate an application’s

dynamic functions.

• Test coverage data—Information that reveals which code paths are or are not

executed when an application is tested enables users to create more complete

tests.

• Event markers—Signiﬁcant events in the execution of the program (for

example, entering a routine) can be marked to permit later ﬁltering of the

data.

Coverage Analyzer for VMS Systems.

9.7 DEC Test Manager

DEC Test Manager is a component of DECset. Like the other components of

DECset, it provides a DECwindows Motif user interface and a consistent look and

feel across platforms. It also provides a command-line user interface.

DEC Test Manager is based on the concept of regression testing. Regression

testing is a method of ensuring that a program being developed runs correctly

and that new features added to the program do not affect the correct execution of

previously tested features.

In regression testing, users run established software tests and compare the actual

test results with the results that were expected. If these actual results do not

agree with the expected results, the software being tested may contain errors. If

errors do exist, the software being tested is said to have regressed.

DEC Test Manager automates regression testing of software during the

development and maintenance phases by executing user-supplied tests and

automatically comparing the results with expected test results. Programmers

supply and select the tests they want to run.

The use of DEC Test Manager by itself can improve programmer productivity and

software reliability. You can organize, run, compare, and store test results

efﬁciently. You can repeat tests and review results as often as needed.

Integration of the DEC Test Manager with PCA and CMS provides a further

enhanced testing environment with corresponding productivity gains.

Manager for VMS Systems.
