Coverage Analysis

The project aims are as follows:

• To perform automated coverage testing on the RTEMS code base and analyse the object level coverage provided by the RTEMS test suite
• Identify and report parts of code that are not being exercised under the test suites
• Analyse each case separately and classify into categories previously identified.
• Address each of these cases and eliminate them.

We took up erc32/sparc as the first BSP/ARCH for coverage.

The coverage stats when we started off for erc32/sparc are as follows:

Total Uncovered Ranges: 208 Total Bytes Analysed: 71604 Total Bytes not executed: 2732 Percentage of executed bytes: 0.9618 Percentage of not executed bytes: 0.03815

The coverage stats as per the mid term evaluations were as follows:

Total uncovered ranges: 83 Total Bytes analyzed: 70900 Bytes not executed: 944 Percentage executed: 0.9867 Percentage not executed: 0.01331

The coverage stats as per 08/01/2009 are as follows:

Total uncovered ranges: 16 Total Bytes Analyzed: 70916 Total Bytes Not Executed: 148 Percentage Executed: 0.9979 Percentage Not Executed: 0.002087
