Coverage Analysis
|
|
=================
|
|
|
|
RTEMS is used in many critical systems. It is important that the RTEMS Project
|
|
ensure that the RTEMS product is tested as thoroughly as possible. With this
|
|
goal in mind, the RTEMS test suite was expanded with the goal that 100% of the
|
|
RTEMS executive is tested.
|
|
|
|
RTEMS-TESTER takes the following arguments to produce coverage reports:
|
|
|
|
`--coverage :`
|
|
When the coverage option is enabled the tester produces coverage reports for
|
|
all the symbols in cpukit. To generate a coverage report for a specific
|
|
symbol-set ( e.g.: score) the symbol-set is passed as an argument to the
|
|
option, e.g.: --coverage=score.
|
|
|
|
`--no-clean :`
|
|
Tells the script not to delete the .cov trace files generated while running
|
|
the coverage. These trace files are used for debugging purposes and will not
|
|
be needed for a normal user.
|
|
|
|
For example: To generate a coverage report of hello.exe for leon3 on SIS, the
|
|
following command is used:
|
|
|
|
.. code-block:: none
|
|
|
|
rtems-test \
|
|
--rtems-tools=$HOME/development/rtems/5 \
|
|
--log=coverage_analysis.log \
|
|
--no-clean \
|
|
--coverage \
|
|
--rtems-bsp=leon3-sis-cov \
|
|
$HOME/development/rtems/kernel/leon3/sparc-rtems5/c/leon3/testsuites/samples/hello.exe
|
|
|
|
The command will create the coverage report in the following tree structure:
|
|
|
|
.. code-block:: none
|
|
|
|
├── coverage_analysis.log
|
|

|
|
│ └── uncovered.txt
|
|
└── leon3-sis-report.html
|
|
|
|
The html on top of the directory, i.e., leon3-sis-report.html is the top level
|
|
navigation for the coverage analysis report and will let the user browse through
|
|
all the generated reports from different subsystems.
