179.1. Test Programs
Some Mbed TLS specific tests are built and can be used to verify correct operation of the Mbed TLS library.
This test executes the internal Mbed TLS sanity tests to verify correct operation of the various features.
This is a simple sanity test that the Mbed TLS headers can be included in C++ compilations.
When an eCos network configuration is available (lwIP or FreeBSD) then this test will perform a client/server local loopback SSL connection using certificates. This is a complete test of a secure
HTTPSconnection using BSD style sockets. To make it easier to work with either the client or the server side the source for the test is split into multiple files, with the client and server side implementations being in their own source files. The relevant client and server side sources are, lightly modified for eCos, versions of the original Mbed TLS source files found respectively in
The following is example output from a run of the test:
