Having a problem asserting that an element does not exist.

[Bobby Johnson (NotMyself)]

I don't seem to be able to figure out how to tell if an element does
not exist in a way that makes me confident that the test is actually
valid. Here is my scenario. I am writing a bit a functionality that
will prompt the user using impromptu if a cookie does not exist. If
the cookie does exist, it should not prompt the user. Here is my spec:

describe 'and the user has already been notified of an error for the
specific date'
mock_request().and_return('{ "tradeDateIsValid" : false }',
'application/json')

$.cookie($('#ExportDate').val(), "true");

$(document).fileLoadHealthCheck({
datePicker: '#ExportDate',
notificationArea: '#HealthCheckArea'
});

it 'should display the red light'
$
('#HealthCheckArea').children('img').attr('src').should.include
'red_light.png'
end

it 'should make the health check area visible'
$('#HealthCheckArea').should.be_visible
end

it 'should not warn the user'
$('#jqibox').should.be_null
end
end

How should I be validating that #jqibox does not exist in the dom?

$('#jqibox') will return a jQuery selector, even if it doesn't find anything, so it won't evaluate to null. However, the length of the object should be zero (meaning that jQuery did not match any elements).

So substitute $('#jqibox').should.be_empty in, and you should be all set! :-)

Hrm... this works as long as I have no other specs. Here is the full
spec file am I missing something?

describe 'when a page with the file load health check initially
loads'

it 'should have the health check area not visible'
$('#HealthCheckArea').should.not.be_visible
end

it 'should have the green light already loaded'

$
('#HealthCheckArea').children('img').attr('src').should.include

'green_light.png'
end
end


describe 'when checking the health of the currently selected trade
date'

before_each
end
after_each
$.cookie($('#ExportDate').val(), null);
$.prompt.close();
end

describe 'and all files have loaded for the given date'
mock_request().and_return('{ "tradeDateIsValid" : true }',
'application/json')

$(document).fileLoadHealthCheck({
datePicker: '#ExportDate',
notificationArea: '#HealthCheckArea'
});

it 'should display the green light'

$
('#HealthCheckArea').children('img').attr('src').should.include

'green_light.png'

end

it 'should make the health check area visible'
$('#HealthCheckArea').should.be_visible
end

end

describe 'and all files have not loaded for the given date'

mock_request().and_return('{ "tradeDateIsValid" : false }',
'application/json')

$(document).fileLoadHealthCheck({
datePicker: '#ExportDate',
notificationArea: '#HealthCheckArea'
});

it 'should display the red light'
$
('#HealthCheckArea').children('img').attr('src').should.include
'red_light.png'
end

it 'should make the health check area visible'
$('#HealthCheckArea').should.be_visible
end

it 'should warn the user that the given date is incomplete'
$('#jqibox').should.be_visible
end
end

describe 'and the user has already been notified of an error for
the specific date'
mock_request().and_return('{ "tradeDateIsValid" : false }',
'application/json')

$.cookie($('#ExportDate').val(), "true");

$(document).fileLoadHealthCheck({
datePicker: '#ExportDate',
notificationArea: '#HealthCheckArea'
});

it 'should display the red light'
$
('#HealthCheckArea').children('img').attr('src').should.include
'red_light.png'
end

it 'should make the health check area visible'
$('#HealthCheckArea').should.be_visible
end

it 'should not warn the user'

$('#jqibox').should.be_empty
end
end
end

Oh god, I am friggin dense. The prompt fades out... 8(

adding a $('#jqibox').remove(); in my after_each did the trick.

Sorry for the newb flailing...
