The invention is applicable to the technical field of embedded software detection, and provides a method for detecting uninitialized variables and terminal equipment, and the method comprises the steps: resetting a tested system, and enabling a pointer to point to a main function of the tested system; Filling specified data in a memory segment for storing a global variable in the tested system; Enabling a pointer to run to a function position where variable initialization is finished, reading the memory segment data, and obtaining the total number of memory units corresponding to the name of the global variable and the total number of units of the specified data; And when the total number of the memory units corresponding to the name of the global variable is the same as the total number of the units of the specified data, determining that the global variable is an uninitialized global variable. According to the method, uninitialized global variables in the embedded software can be rapidly detected through a 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 is referenced, its initial value is not fixed. When global variables are referenced, the running results are unpredictable, and the phenomenon is different each time, which not only may cause economic losses, but also makes it difficult for software developers to locate problems, resulting in the inability to find all software vulnerabilities and increasing software development. The time investment of personnel debugging the program. Contents of the invention [0003] In view of this, an embodiment of the present invention provides a method for detecting uninitialized variables and a...
