# proc mytestMain*() =
#   # put anything you want here
# and then give it a name `test_mytest.nim`
# the `mytest` part should match between
# the proc name and the module name

# if this executable called without any params
# it will execute each of the test by executing itself
# repeatedly until all sub-tests are executed.
# you can execute the sub-test by a number start from zero.
