ABAP Runtime Environment (BC-ABA)

Code coverage is a measure used in testing of software for quality assurance. Code coverage measures the extent to which a program or module is exercised by a unit test, test suite, or production use of the software. A high degree of code coverage is an indication that the software under test has been adequately tested; most of the code under test has been executed.

In the ABAP Web AS, code coverage can be measured with the Coverage Analyzer (transaction SCOV).

Depending upon the release, the Coverage Analyzer provides up to three different measures of code coverage. These are as follows:

• Procedure coverage: The proportion of procedures (form routines, methods, modules) that have been called during the measured period. Available as of Release 6.40.
• Statement coverage: The proportion of source code statements that have been executed during the measured period. Available as of Release 7.02.
• Branch coverage: Commonly, the proportion of control structures that have evaluated to both true and false during the measured period. In the Coverage Analyzer, the proportion of all branches in control structures that have been executed. Available as of Release 7.02.

There is a considerable literature as to the significance and use of code coverage in effective testing of software. Branch coverage is considered to be the most significant measure of code coverage, since a high degree of branch coverage indicates that most paths through a program or module have been executed.
