Software testing method and device

The invention discloses a software testing method and device. The software testing method includes that sending a test message to an appointed part to be tested in a network program to be tested, and enabling the appointed part to be tested to process the test message and send the processed test message to a target device, wherein the appointed part to be tested in the network program to be tested is determined through reverse analysis; receiving an execution result from the target device, and determining a test result according to the execution result. According to the software testing method, the part to be tested in the network program to be tested is determined through the reverse analysis, the test message is sent to the appointed part to be tested, and therefore, the message to be tested can be smartly sent through multiple threads or a progress set to achieve high concurrency to test network software online on a large scale and improve the test efficiency. Because the test message is sent to the appoin
