Problems solved by technology

The automatic theorem proving system is a general search process, which is relatively successful in solving various combination problems; the interactive theorem proving system needs to interact with the user, requiring the user to provide the most creative part of the verification (establishing assertions, etc.), so its Low efficiency, difficult to verify large systems

Embodiment Construction

[0046] The present invention will be further described below in conjunction with the accompanying drawings.

[0047] Such as figure 1 As shown, a mixed method for verifying the correctness of a JavaScript program includes the following steps:

[0048] Step 1. Determine whether the program component contains dynamic grammatical features. If so, the program component is divided into two parts: the static part and the dynamic part: the static part does not contain the dynamic grammatical feature, and the program proof method is used for verification; the dynamic part uses the model detection method For verification, the combination of static and dynamic parts is divided into dynamic parts, and the program proof method is used for verification.

[0049] Step 2. Statize the divided static part through the program specification method, and use the open temporal logic to formalize the JavaScript program; the open temporal logic expands the calculation tree logic, specifically by in...

Abstract

The invention discloses a method for verifying the correctness of a JavaScript procedure in a mixed mode. The method for verifying the correctness of the JavaScript procedure in the mixed mode comprises the following steps that the JavaScript procedure is divided into a static portion and a dynamic portion; the correctness of the JavaScript procedure is specified based on the open temporal logic; the correction of the static portion and the correction of the composition of the static portion and the dynamic portion are verified according to the procedure verification method; the correctness of the dynamic portion is verified according to the model checking method. The method for verifying the correctness of the JavaScript procedure in the mixed mode can be applicable to multiple grammar characteristics and application occasions of the JavaScript language, can support an automatic model detection tool and can effectively reduce the state searching space, and therefore the verification efficiency of the JavaScript procedure is effectively improved.

Description

technical field [0001] The invention belongs to the field of computer software verification, in particular to a method for verifying the correctness of JavaScript programs. Background technique [0002] JavaScript language is a scripting language widely used in Internet applications. Because it supports various dynamic grammatical features, JavaScript language has good expressive ability and flexibility. Using JavaScript language can improve the development efficiency and speed of software systems, and improve Readability and reusability of software systems. [0003] The JavaScript language supports dynamic grammatical features including: dynamic type, implicit type conversion, runtime solution and reflection, etc. Due to the introduction of various dynamic grammatical features, JavaScript programs are difficult to use traditional program proofs and model checking (model checking) methods. verify. [0004] Formal method is to use mathematical methods to study related probl...
