Function test method and device based on bus development environment

The invention discloses a function test method and device based on a bus development environment. The method is applied to a bus box, the bus box is connected between a tested controller and a bus, has a gateway simulation function and is provided with a test configuration interface, and the method comprises the following steps: receiving test configuration parameters inputted by a user through the test configuration interface, and carrying out corresponding test configuration according to the test configuration parameters; receiving the bus data, and processing the bus data based on the testconfiguration; and if the processed bus data exists, sending the processed bus data to the tested controller so as to realize testing of related functions of the tested controller. According to the method and the device, a complex test framework does not need to be built, expensive equipment does not need to be arranged, and in the real vehicle test process, the received data signal can be directly changed through the met
