我正在使用http://railstutorial.org/学习Ruby on Rails。在阅读本书第6章时。我遇到了我的用户领域变成零。进而导致authenticate方法失败。
仅供参考，与本教程中提到的宝石不同，我使用过rails 5和ruby 2.6是所有最新的宝石。
这是运行测试后的Rspec结果
$bundle exec rspec spec/
including Capybara::DSL in the global scope is not recommended!

Failures:
1) User should be valid
Failure/Error: it { should be_valid }
expected #<User id: nil, name: nil, email: nil, created_at: nil, updated_at: nil, password_digest: nil> to be valid, but got errors: Password can't be blank

2) User return value of authenticate method with valid password should When you call a matcher in an example without a String, like this:
specify { expect(object).to matcher }
or this:
it { is_expected.to matcher }
RSpec expects the matcher to have a #description method. You should either
add a String to the example this matcher is being used in, or give it a
description method. Then you won't have to suffer this lengthy warning again.

Deprecation Warnings:
Using `should` from rspec-expectations' old `:should` syntax without explicitly enabling the syntax is deprecated. Use the new `:expect` syntax or explicitly enable `:should` with `config.expect_with(:rspec) { |c| c.syntax = :should }` instead. Called from /home/user/rails_projects/sample_app/spec/models/user_spec.rb:96:in `block (4 levels) in <top (required)>'.
If you need more of the backtrace for any of these deprecations to
identify where to make the necessary changes, you can configure
`config.raise_errors_for_deprecations!`, and it will turn the
deprecation warnings into errors, giving you the full backtrace.
