Wings-enterprise-level unit use case automatic coding engine can move software testing to the left (in advance intervention) to unit testing. The Wings product allows the computer to perform global analysis and in-depth understanding of the program under test, and then the computer performs fully automatic unit test coding, while ensuring that the automatically written code runs directly without syntax and semantic errors. This computer-based intelligent algorithm Automatically generated test code to verify that the logic input and output of the source code written by the developer is right or wrong, and belongs to the most high-end test mode in the field of software testing. Great strides completed the overall technical leap of related technologies, and achieved multi-party commercial landing verification in actual user scenarios.
