Vinayak,
You are mixing several things, it seems.
What you should do in your unit test is something along the lines:
ParameterHandler prm;
MyLovelyParameters::declare_parameters(prm);
// parameters
std::ostringstream oss;
oss << "set Something = 3" << std::endl
<< "set LAMMPS input = " << SOURCE_DIR <<
"/relative/path/to/input.xyz" << std::endl;
prm.parse_input_from_string(oss.str().c_str());
// use it to do the same as in main.cc
// (depends on how things are implemented)
Obviously, you need to adjust this code to what you are actually doing.
The point is, dealII have functionality to run user tests in two ways:
1) take the main executable and pass .rpm file as an argument
This won't work when you need some auxiliary data which is a part of the
test.
That is because you don't know the path from which the test will be
executed.
2) compile .cc file and run it. In this case, you should populate whatever
parameter
within that .cc file. But this also requires that you separate your program
into a library (say with a single class Problem) and
executable main.cc which actually creates an instance of that class and
runs it.
So what you do here is essentially the same thing as your main.cc but you
feed parameters NOT from the command line argument,
but create them yourself dynamically (SOURCE_DIR will be dynamic macro
depending on where you actually configure/build).
Regards,
Denis
