A test method for simulating system failure based on usb disk

Abstract

The invention discloses a test method for simulating system faults based on a USB disk. Connect the USB disk to the device under test; restart the target test system in the device under test to trigger the fault corresponding to the preset fault injection script; execute the test in the fault state; remove the target USB disk after the test is completed. The function of making a USB disk into a system installation startup disk, and connecting the USB disk with preset faults to the device of the system under test, so that the fault is directly injected into the system under test, at this time, the verification of the fault handling process can be carried out. Moreover, the fault can be automatically resolved after the USB disk is removed, so as to realize the next step of processing the system under test after simulating the fault repair, which not only achieves the purpose of the test, but also makes the test method more simple, direct and accurate.

Description

technical field [0001] The invention relates to the technical field of software system testing, in particular to a testing method for simulating system faults based on a USB disk. Background technique [0002] In the process of system testing, in order to test the reliability of the system, it is necessary to simulate various abnormal faults for testing, so that various methods are used to simulate the fault scene to the greatest extent. Therefore, various methods are used to simulate the fault scene to the greatest extent, so as to verify the reliability and fault recovery function of the system. [0003] Some failure simulations can be done manually directly, such as plugging and unplugging components to simulate component failures and system hot standby. Some faults can be simulated remotely by scripts written directly, such as the port failure of the switch, the restart of the system, etc. However, some system startup faults cannot be simulated closer to the fault site...

AI Technical Summary

Problems solved by technology

However, some system startup faults cannot be simulated closer to the fault site through manual or scripting. For example, the system is suspended during the system upgrade process and cannot continue to upgrade, and system data is lost during system startup.

Although a similar scenario can be simulated manually or with a script, the timing of the injection cannot be grasped manually, and the simple and rude method often kills some processes that affect the fault. Systems with relatively complex software are often very difficult to implement, such as remote monitoring of various processes in the system, controlling the duration of fault states, etc., which is time-consuming and laborious and often fails to achieve the expected results
