[英]How to test enum validation?
I have a variable that has a specific set of answer options.我有一个具有一组特定答案选项的变量。 In my model I have:在我的模型中,我有:
validates :article_type, presence: true
enum article_type: [ :type1, :type2, :type3 ]
I have the following model test:我有以下模型测试:
test "type test" do
assert @article.valid?
@article.article_type= "type1"
assert @article.valid?
@article.article_type= "type5"
assert_not @article.valid?
end
Error: The line @article.article_type= "type5"
generates the error: ArgumentError: 'type5' is not a valid article_type
.错误: @article.article_type= "type5"
行生成错误: ArgumentError: 'type5' is not a valid article_type
。
For all other sorts of validations where I include invalid data and then use assert_not
these kinds of tests work.对于我包含无效数据然后使用assert_not
的所有其他类型的验证,这些类型的测试工作。 Why not in this case?为什么不在这种情况下? How should I rewrite this model test?我应该如何重写这个模型测试?
Here's the explanation from Rails team: https://github.com/rails/rails/issues/13971这是 Rails 团队的解释: https ://github.com/rails/rails/issues/13971
If you want to test that invalid values are rejected, use assert_raises
to expect the ArgumentError
如果要测试无效值是否被拒绝,请使用assert_raises
来预期ArgumentError
test "type test" do
assert @article.valid?
@article.article_type = "type1"
assert @article.valid?
assert_raises ArgumentError do
@article.article_type = "type5"
assert_not @article.valid?
end
end
