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-serveris 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-clientsends many different queries to a large range of addresses and values to test the communication between the client and the server.
unit-test-clientrun a full unit test suite. These programs are essential to test the Modbus protocol implementation and libmodbus behavior.
bandwidth-clientreturn very useful information about the performance of transfert rate between the server and the client.
bandwidth-server-onecan only handles one connection at once with a client whereas
bandwidth-server-many-upopens a connection for each new clients (with a limit).
