Sometime it is necessary to execute a test application on a different machine than the one running the qmtest application itself. For example, if the test involves executing an application previously cross-compiled, the binary needs to be uploaded to an appropriate host and run there.

QMTest provides a host abstraction for this purpose. To use this mechanism, test classes need to provide explicit support for it. A number of built-in test classes support cross-testing.

To run the compile test on a remote target machine, specify a CompilationTest.target variable in the context file to contain a host descriptor:

CompilationTest.compiler=/path/to/cross_compiler
CompilationTest.target=ssh_host.SSHHost(host_name="192.168.0.100")
   

This will run the compiled executable on the machine with the IP address 192.168.0.100, using ssh for communication.
