The present invention is applicable to the technical field of embedded software detection, and provides a detection method for uninitialized variables and a terminal device. The method includes: resetting the system under test, making the pointer point to the main function of the system under test; Fill the specified data in the memory segment storing the global variable in the test system; run the pointer to the function position where the variable initialization is completed, read the data of the memory segment, and obtain the total number of memory units corresponding to the name of the global variable and the specified data The total number of units; when the total number of memory units corresponding to the name of the global variable is the same as the total number of units of the specified data, then determine that the global variable is an uninitialized global variable. The method can realize rapid detection of uninitialized global variables in the embedded software through the script automatic detection method.
Description
technical field [0001] The invention belongs to the technical field of embedded unit testing, and in particular relates to a detection method for uninitialized variables and a terminal device. Background technique [0002] The referenced global variables need to be declared and initialized before the embedded software system runs. If the global variable is not initialized before the variable reference, its initial value is not fixed. When a global variable is referenced, its operation result is unpredictable, and the phenomenon is different each time, which may not only bring economic losses, but also bring difficulties to software developers in locating the problem, resulting in the inability to find all software vulnerabilities and increasing software development. Human time investment in debugging the program. SUMMARY OF THE INVENTION [0003] In view of this, the embodiments of the present invention provide a method for detecting uninitialized variables and a termina...
