setUp function

void setUp(
  1. dynamic callback(

    Registers a function to be run before tests.

    This function will be called before each test is run. callback may be asynchronous; if so, it must return a Future.

    If this is called within a test group, it applies only to tests in that group. callback will be run after any set-up callbacks in parent groups or at the top level.

    Each callback at the top level or in a given group will be run in the order they were declared.


    void setUp(dynamic Function() callback) => _declarer.setUp(callback);
