Abstract

The application discloses a comparison method and device of file differences. The method includes: obtaining file contents of a file before a change and file contents after the change; converting thefile contents before the change to a first matrix, and converting the file contents after the change to a second matrix; acquiring a first feature vector of the first matrix and a second feature vector of the second matrix; converting the first matrix to a first hash table according to the first feature vector, and converting the second matrix to a second hash table according to the second featurevector; and determining the differences of smallest structure units of the file contents before the change and the file contents after the change according to a comparison result of the first hash table and the second hash table. Through the method, the problem that in the related art, version management software cannot quickly find changes of smallest structure units of file contents before andafter file changes is solved.

Description

technical field [0001] The present application relates to the field of document difference comparison, in particular, to a method and device for document difference comparison. Background technique [0002] In software development and testing, quickly finding and confirming file changes is an important link to ensure the quality and speed of software development. The comparison of file differences is often used to confirm whether the changes of two versions of a file meet expectations. Specifically, in software development, through the comparison of file differences, you can quickly know whether the changes of software files are consistent with the requirements documents; in the test, pass File difference comparison can quickly determine what needs to be tested, formulate a test plan, and before integration testing, some software design defects can be found through file difference comparison. [0003] In related technologies, file difference comparison is usually done by ve...
