Problems solved by technology

Random testing may hit any function point in the input state space, and it may hit a function point that the tester has not thought of, thereby reducing the workload of the tester, but this randomness may lead to repeated coverage of the function point, random Tests often fail to achieve the expected test target set coverage, and many test vectors are redundant for function points, requiring multiple rebuild tests, which reduces test reliability and test efficiency

Embodiment 1

[0050] The embodiment of the present invention provides a test system for large-scale software, see figure 1 , the test system consists of:

[0051] Vector generation module 1, is used for adopting the method for random test to generate test vector for the object under test;

[0052] The monitoring module 2 is configured to monitor the path coverage rate of the test target set of the object under test according to the generated test vector, and when the path coverage rate of the test target set reaches a critical state, search for and acquire the Paths not covered by the set of test targets for the object under test; and,

[0053] The model calculation module 3 is configured to establish a mathematical model according to the paths not covered by the test target set, and solve the mathematical model to obtain test vectors of the paths not covered by the test target set.

[0054] It should be noted that before the test is executed, a test platform is built to integrate various...

Embodiment 2

Abstract

The present invention discloses a test system and method for scale software. The test system comprises: a vector generating module, used for generating a test vector by a function drive and random test method for a tested object; a monitoring module, used for monitoring a path coverage of a test target set of the tested object according to the generated test vector, and when it it monitored that the path coverage of the test target set reaches a critical state, searching for and acquiring a path that is not covered of the test target set of the tested object; and a model calculation module, used for establishing a mathematical model according to the path that is not covered of the test target set, and solving the mathematical model to obtain a test vector of the path that is not covered of the test target set. The present invention provides a simple test vector set construction scheme, which can improve the coverage of the test target set and improve reliability and efficiency of tests.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a large-scale software testing system and method. Background technique [0002] Software testing describes a process used to facilitate the verification of the correctness, integrity, security, and quality of software. In other words, software testing is a process of reviewing or comparing the actual output with the expected output. The classic definition of software testing is: the process of operating the program under specified conditions to find program errors, measure the quality of the software, and evaluate whether it can meet the design requirements. Software testing is an important technical means to ensure software quality in software development and software verification and confirmation activities. [0003] The real problem faced by software testing is that for software with complex algorithm logic and large-scale input state space, it is difficult for the test to...
