85 * The macro UNIT_TEST() is used to create a linker generated list entry. These

87 * The list entries are used both by the implementation of the ut command as
88 * well as in a related Python test.
90 * For Python testing the subtests are collected in Python function
91 * generate_ut_subtest() by applying a regular expression to the lines of file

93 * matched by the expression.
