These tests + * fall into two categories; run_api_tests() checks basic functionality of the + * kprobes API, and run_test_cases() is a comprehensive test for kprobes + * instruction decoding and simulation. + * + * run_test_cases() first checks the kprobes decoding table for self consistency + * (using table_test()) then executes a series of test cases for each of the CPU + * instruction forms. coverage_start() and coverage_end() are used to verify + * that these test cases cover all of the possible combinations of instructions + * described by the kprobes decoding tables. + * + * The individual test cases are in kprobes-test-arm.c and kprobes-test-thumb.c + * which use the macros defined in kprobes-test.h. The rest of this + * documentation will describe the operation of the framework used by these + * test cases. + */ + +/* * TESTING METHODOLOGY * ------------------- * |
