Instance Method Details

#stub(name, val_or_callable, *block_args)

Add a temporary stubbed method replacing name for the duration of the block. If val_or_callable responds to #call, then it returns the result of calling it, otherwise returns the value as-is. If stubbed method yields a block, block_args will be passed along. Cleans up the stub at the end of the block. The method name must exist before stubbing.

def test_stale_eh
  obj_under_test = Something.new
  refute obj_under_test.stale?

  Time.stub :now, Time.at(0) do
    assert obj_under_test.stale?

end
