when testing a directive, I get typeerror compile is not a function

When I try to test my directive I get the TypeError: compile is not a function. Here is my test case:

describe('directive tests', function () {
var element, $compile, scope;

beforeEach(module('App'));

beforeEach(inject(function (_$compile_, $rootScope) {
    $compile = _$compile_;
    scope = $rootScope.$new();
}));

it('should be Hello', function () {
    element = $compile('<div Hello></div>')(scope);
    ...
});

});

If I comment the like that define the module, (beforeEach(modue('App')), the compile works, but I can't get reference to my directive.
