Techniques for tracing the real-time operation of software for the purposes of testing, debugging, or performance analysis are disclosed. Diagnostic instrumentation for generating records containing details of software operation is incorporated in the software by inserting calls to diverse macros or inline functions. Each macro takes an argument specifying both a subsystem and a category of instrumentation within the subsystem. Based on the specified subsystem and category, the instrumentation can be included or excluded from the compiled object code and, if included, can be dynamically enabled at run-time. Disabled instrumentation does not result in a function call, but only a single, inline “if,” thereby reducing overhead. One macro accepts both software parameters and a custom format specifier describing how the parameters should be displayed. However, the parameters are not formatted during logging, nor is the format specifier included in the record. Instead, the formatting is performed when displayed.

The invention discloses a test method of an engine controller software diagnosis module on the basis of the USB-CAN (Universal Serial Bus-Controller Area Network) network communication equipment and the automobile diagnosis instruction set tool of the NI Company (National Instruments). The method comprises the following steps: designing an Excel-based diagnosis software test template file; according to the test template, compiling a diagnosis software test case which conforms to a test template format; obtaining the test template file input by a user, analyzing the test template appointed by the user, and generating a data structure used for describing a test template test case and controlling a test process; controlling a test flow; analyzing a simulation working condition; generating a diagnosis communication data frame; receiving and transmitting the communication data frame; judging a test result; realizing interaction with the working condition environment of an engine controller; and outputting a test report and a log file. The invention also discloses a test system of the engine controller software diagnosis module on the basis of the USB-CAN network communication equipment and the automobile diagnosis instruction set tool of the NI Company. The test method can improve the test efficiency and the test quality of the test work of the engine controller software diagnosis module.
