# Add an helper method named `let_tmp_file` to spec example, this
# helper will create a temporary file with the content from the block,
# it behave like a normal `let` statement. Also to make things easier temporary
# debug it will create another `let` statement with the actual content of the block.
#
# Example:
# ```
# let_tmp_file(:hello_world_file) { "Hello world" } # return a path to a tmp file containing "Hello World"
# and will create this debug `let`, the value of the file will be the same.
# let(:hello_world_file_content) # return "Hello world"
#
