次のメソッドは、テストに適切に合格します。
def associate_grid_location
devices.each do |device|
if device.grid_location and grid_location_id.nil?
update_attribute(:grid_location_name,device.grid_location.grid_name)
update_attribute(:grid_location_id,device.grid_location_id)
break
end
end
end
ただし、このメソッドの呼び出しで同じテスト ロジックを実行すると、各キャビネットの grid_location_name と grid_location_id の更新に失敗します。
def self.associate_grid_locations
Cabinet.all.each do |cabinet|
cabinet.associate_grid_location
end
end
失敗する理由を教えてください。
合格テスト:
test "Cabinet associate grid location from device where device has grid location" do
@cabinet = cabinets(:one)
@cabinet.grid_location_id = nil
@device = devices(:one)
@grid_location = grid_locations(:one)
@grid_location.grid_name = "test location"
@device.grid_location = @grid_location
@cabinet.devices << @device
@cabinet.associate_grid_location
assert_equal @grid_location.grid_name, @cabinet.grid_location_name, "Failed: Did not update cabinet grid location"
assert_equal @device.grid_location.id, @cabinet.grid_location_id, "Failed: Did not update cabinet grid location"
end
失敗したテスト:
test "Cabinet associate grid location from device where device has grid location (Called on Cabinet)" do
@cabinet = cabinets(:one)
@cabinet.grid_location_id = nil
@device = devices(:one)
@grid_location = grid_locations(:one)
@grid_location.grid_name = "test location"
@device.grid_location = @grid_location
@cabinet.devices << @device
Cabinet.associate_grid_locations
assert_equal @grid_location.grid_name, @cabinet.grid_location_name, "Failed: Did not update cabinet grid location"
assert_equal @device.grid_location.id, @cabinet.grid_location_id, "Failed: Did not update cabinet grid location"
end
ありがとうございました。
