LANG.FUNCS.ASSERTS : Not Enough Assertions

JavaScript is not currently enabled, but is required for full CodeSonar manual search and browse functionality.

If you are viewing this file in your hub's Web GUI, enable JavaScript in your browser: you will also need it for GUI functionality.

If you opened this file directly from disk, your browser may be directly suppressing JavaScript functionality: certain browsers perform this suppression on local files (but not files delivered by web servers) for security reasons.

If you access the manual through the hub's Web GUI, the functionality will not be suppressed because the hub is a web server.
Alternatively, your browser may allow you to explicitly disable the security setting that suppresses functionality. See the CodeSonar FAQ for more information.

A function does not contain enough assertion statements.

The functions whose calls should be considered "assertion statements" are specified by the ASSERT_FAIL_FUNCTIONS setting. (The factory setting includes assert() and other functions.)

The definition of "enough" is specified by the MIN_ASSERTS setting. (The factory setting is 2.)

Functions are not subjected to this check if they contain fewer lines with code than the minimum specified by the MIN_ASSERTS_FUNCTION_LENGTH setting. (The factory setting is 0.)
