+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
+-----------------
+It's necessary to launch this server before run random-test-client. By
+default, it receives and responses to Modbus query on the localhost
+and port 1502.
+
+random-test-client
+------------------
+This programm 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
+unit-test-client
+----------------
+By default, this program sends some queries with the values defined in
+unit-test.h and checks the responses. These programs are useful to
+test the protocol implementation.
+
+bandwidth-server-one
+bandwidth-server-many-up
+bandwidth-client
+-----------------------
+It returns some very useful informations about the performance of
+transfert rate between the server and the client.
+
+- bandwidth-server-one: it can handles only one connection with a client.
+- bandwidth-server-many-up: it opens a connection each time a new client asks
+ for, but the number of connection is limited. The same server process handles
+ all the connections.
