如何在Ruby测试中模拟HTML多选输入

post :create, :post => { :multiselect1 => ['value1', 'value2'] , :multiselect2 => ['value3', 'value4'] }

"post[multiselect1][]"

"post[multiselect2][]"

post :create, {:multiselect1 => ['value1', 'value2'] , :multiselect2 => ['value3', 'value4'] }

"multiselect1[]"

"multiselect2[]"
