Compilation

After installation, you can use pkg-config to compile these tests. For example, to compile random-test-server run:

gcc random-test-server.c -o random-test-server pkg-config --libs --cflags libmodbus

• random-test-server is necessary to launch a server before running random-test-client. By default, it receives and replies to Modbus query on the localhost and port 1502.

• random-test-client sends many different queries to a large range of addresses and values to test the communication between the client and the server.

• unit-test-server and unit-test-client run a full unit test suite. These programs are essential to test the Modbus protocol implementation and libmodbus behavior.

• bandwidth-server-one, bandwidth-server-many-up and bandwidth-client return very useful information about the performance of transfert rate between the server and the client. bandwidth-server-one can only handles one connection at once with a client whereas bandwidth-server-many-up opens a connection for each new clients (with a limit).
