Abstract

The invention discloses an intelligent contract operation code coverage rate calculation method and system. The method comprises the steps that when a source code file of an intelligent contract is obtained, a deployment request is sent to a blockchain, and thus the blockchain can deploy the intelligent contract according to the deployment request and return a contract address of the intelligent contract; according to the contract address of the intelligent contract returned by the blockchain, identification information of the intelligent contract is obtained, a transaction request which contains the identification information is constructed, the transaction request is sent to the blockchain, and thus the blockchain can output a corresponding statistical result file to a preset storage medium according to the identification information of the transaction request; according to the identification information, the statistic result file is obtained in the storage medium, and according to the statistic result file and a preset formula, the intelligent contract coverage operation code rate is calculated. The method and system simplify the calculation process of the intelligent contract coverage rate and improve the calculation precision of the intelligent contract coverage rate.

Description

technical field

[0001] The present invention relates to the technical field of block chains, in particular to a method and system for calculating the coverage ratio of operation codes of smart contracts. Background technique

[0002] Coverage is a measure used to measure the integrity of software functional testing and a measure of the effectiveness of testing techniques. At present, there are mainly two coverage calculation methods in the blockchain field. One is the interface method for manual or script recording of test case execution calls, followed by statistical summary of data, and finally output of analysis results. The other is to use the log event mechanism of the smart contract, first transcompile the source code of the smart contract, insert the custom log event information by analyzing the source code, and send a transaction request to the blockchain, and finally analyze it through the script Log event information of blockchain transactions, summarize the data...
