A method and device for detecting and locating exception throwing processing defects

Abstract

The invention discloses a method and a device for detecting and locating exception throwing processing defects. In this method, the program to be tested is firstly instrumented, and the control code is inserted before the method that may throw an exception, so that after the program to be tested is executed, the information of the instrumented method and the call information are output through the control code, and the matching of the configuration information triggered by the exception is determined. Whether to throw an exception and what kind of exception is thrown. Then, according to the list of instrumented methods, a collection of exception types that may be triggered is obtained. Then, according to the exception type set, a suspicious exception trigger test is performed on each exception type to obtain a suspicious method exception information set. Finally, the exception throwing defect location information is obtained by performing the context combination exception trigger test on each suspicious method exception information in the suspicious method exception information set. The present invention greatly reduces the scope of abnormal throwing and processing defect positioning through the filtering of suspicious abnormality triggering tests, thereby greatly improving the positioning efficiency.

Description

technical field [0001] The invention relates to testing technology, in particular to testing of exception throwing processing defects. Background technique [0002] Exception handling (Exception Handling) is a mechanism in high-level programming languages ​​to deal with abnormal conditions that occur in software or information systems. Exception handling is usually a measure taken to prevent unknown errors. It provides an effective method for dealing with certain types of errors, which can improve programming efficiency and program robustness. In Android applications, there are two ways to handle exceptions. One is to use the throws keyword in the method signature to throw exceptions, and the other is to use try and catch modules to handle exceptions that occur in the program. However, it is very difficult to verify the correctness of the exception handling module of an Android application, especially when it involves exception handling code related to external resource ope...
