Method and device for processing multi-version test data

The invention discloses a method for processing multi-version test data. The method comprises the following steps: acquiring a difference result between a current version and a previous version, and acquiring a code coverage rate of the previous version; performing differential processing on the difference result between the current version and the previous version, and the code coverage rate of the previous version to obtain a processed code coverage rate of the previous version; acquiring a code coverage rate of the current version; and combining the code coverage rate of the current version with the code coverage rate of the previous version to obtain a total code coverage rate of the current version and the previous version. The invention also discloses a device for processing the multi-version test data. Through adoption of the method and the device, combination processing of test data among a plurality of versions is realized, so that convenience is brought to checking of the test data and quality evalu
