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