Embodiment Construction

[0026] Below in conjunction with the embodiment of the present invention figure 1 , figure 2 and image 3 To clearly and completely describe the technical solutions in the embodiments of the present invention, it is obvious that the described embodiment is only one embodiment of the present application, not all of the embodiments.

[0027] like figure 1 Be the flow chart of software dynamic test operation data extraction method of the present invention, concrete implementation steps are as follows:

[0028] Step 101, the garrison process starts the program under test through a system call, and the specific implementation is as follows:

[0029] (1) The program under test

[0030] The program under test can be an ordinary program deployed on a desktop operating system, or a real-time program running on an embedded system; according to the classification of test business, the program under test can be the object of dynamic testing of all software, such as program coverage t...

Abstract

The invention discloses a method for extracting software dynamic test operation data, which comprises the following steps: a resident process starts a program under test through a system call; when the program under test runs to a preset data monitoring point, sends signal; after the garrison process saves the scene, suspend the program under test, and search for a processing routine in the data acquisition processing routine vector table according to the received signal type; the processing routine found is provided by the garrison process Calling, after obtaining the specific operation data at the current location, send a data acquisition completion signal to the resident process; after receiving the acquisition completion signal, the resident process restores the site and makes the program under test continue to run. This method does not require code stubs, does not increase the code size of the program under test, does not affect the operating efficiency of the program under test, and does not depend on the hardware platform. It can obtain rich, accurate and real-time data types, and has high universality.

Description

technical field [0001] The invention belongs to the field of computer software testing, in particular to a method for extracting running data required by dynamic testing of software in an embedded system. Background technique [0002] In software dynamic testing, the extraction methods of program operation data can generally be divided into three categories, which are pure hardware extraction methods, pure software extraction methods and combined software and hardware extraction methods. Among them, the pure hardware method usually uses sampling to obtain program running data, which will inevitably lose some important signals, and its analysis range is also very limited, so it is difficult to obtain satisfactory test results in practical applications. The pure software method generally adopts software instrumentation technology, by inserting probes into the program under test, and using the probes to complete the extraction of operating data. Due to the existence of a large...
