我想知道的TestCase.assertQuerysetEqual方法是如何工作的。 我尝试了不同的方式,他们每个人带我到另一条错误消息。
#create a backup of all records in the tree
tree_record_backup = list(Tree.objects.all())
#do some updates on another table, which should not affect the tree table if everything goes wrong
#check if list of tree records did not changed
tree_record_qs = Tree.objects.all()
#Number1:
self.assertQuerysetEqual(tree_record_qs,[repr(tree_record_backup)])
#Number2:
self.assertQuerysetEqual(tree_record_qs,tree_record_backup)
为数字1出现错误信息:
First list contains 21 additional elements.
First extra element 1:
node.pk: 2 - node: node2 - pk: 2 - level: 0 - ancestor: 2
对于2号错误消息:
AssertionError: Lists differ: ['<Tree: node.pk: 1 - node: ro... != [<Tree: node.pk: 1 - node: roo...
First differing element 0:
<Tree: node.pk: 1 - node: root - pk: 1 - level: 0 - ancestor: 1>
node.pk: 1 - node: root - pk: 1 - level: 0 - ancestor: 1
谢谢你的提示如何正确使用方法assertQuerysetEqual。
