This is close to what I was thinking of, but I am doing the compilation
inside RSpec. My specifications look like this:
it 'fail to compile if foo is assigned to int' do
x = system ENV[COMPILER] test_int_assign_fail.cpp
x.should_not == 0
end
it 'allow use of foo as bool' do
x = system ENV[COMPILER] test_use_as_bool.cpp
x.should == 0
x = system test_use_as_bool
x.should == 0
end
My shell script or batch file sets the environment variables needed to
compile.
My problem is that I do not like the following line in Ruby :
system spec spec1.rb
it looks very inefficient, so I am looking for a better solution.
