我們什么時候在 ruby?? on rails 測驗中使用 assert 和 asert_not，to 有什么區別？例子：
test 'email should not be too long' do
@user.email = 'a' * 244 '@example.com'
assert_not @user.valid?
end
test 'email validation should accept valid addresses' do
valid_addresses = %w[[email protected] [email protected] [email protected]
[email protected] alice [email protected]]
valid_addresses.each do |valid_address|
@user.email = valid_address
assert @user.valid?, "#{valid_address.inspect} should be valid"
end
end

assert_not當您期望結果為 時使用false。

assert當您期望結果為 時使用true。
