The embodiment of the invention discloses an electric vehicle controller model in-the-loop test system and a method. The system comprises an input signal processing module, an output signal processing module, a first controlled object model, a vehicle controller model, and a second controlled object model, wherein the first controlled object model is used for generating a test signal according to a test case and sending the test signal to the vehicle controller model through the input signal processing module; the vehicle controller model is respectively connected with the input signal processing module and the output signal processing module for executing logic processing on the test signal to generate a control command and sending the control command to the second controlled object model through the output signal processing module; and the second controlled object model is used for executing the control command to generate an output signal and sending the output signal to the vehicle controller model through the input signal processing module. The system and the method disclosed by the embodiment of the invention have the advantages that manpower and material resources can be saved; the cost is reduced; the software integration test can be executed at the early development stage of the vehicle controller; and defects in the software can be timely found out and eliminated.

The invention discloses a test device, aims to provide a voltage or current transformer on-line test device without current interruption, a test power source and a standard voltage or current transformer and further discloses a voltage or current transformer on-line test method which is simple to test and operate and flexible in test. The device comprises a CPU (central processing unit) (8), a signal generator (1), an A / D (analog to digital) converter (7), a display module (9), an input interface circuit (2) and a sampling circuit (6), wherein the signal generator (1), the A / D converter (7) and the display module (9) are electrically connected with the CPU (8), the input interface circuit (2) is electrically connected with the signal generator (1) and is electrically connected onto a primary loop (3) on one side of a tested transformer (4), and the sampling circuit (6) is electrically connected with the A / D converter (7) and is electrically connected onto a secondary loop (5) on the other side of the tested transformer (4). Therefore, a loop for on-line test of the tested transformer (4) is formed.

The invention discloses an automatic software automated testing method based on cloud computing, relating to the field of software testing. The method comprises the following steps of: a master server sends a test script to each end server; the end server with received test script tests the test script and returns the test result to the master sever; the master server judges whether all test scripts in the set of test scripts are completely sent; if so, the testing is finished; or, the master server sends a new test script to an end server returning the test result, and performs corresponding steps. In the method, all test scripts are distributed to the end server by the master server, and the end server performs the test scripts one by one and acquires new test script after the test result is returned; therefore, all resources of the end server are ensured to be fully utilized in the whole test procedure and the availability of resources is improved.
