“test/models/user_test.rb”文件中有什么？ –

模型用户测试（名称，电子邮件和通过bcrypt）所以我测试例如密码是空的或具有指定数量的字符。 – Drekoo

https://github.com/Mroczeks/first_project/blob/master/test/models/user_test.rb – Drekoo

此错误的原因似乎user_test.rb文件保存@user对象时要失败验证。试着用下面的代码替换这个测试并运行这个测试时，你会看到验证失败：

test "email addresses should be saved as lower-case" do 
    mixed_case_email = "[email protected]" 
    @user.email = mixed_case_email 

    # Calling `save!` here will raise an exception if failed to save @user. 
    @user.save! 
    assert_equal mixed_case_email.downcase, @user.reload.email 
end

解决您的setup方法相应地满足所有验证，再尝试。

在User模式，你必须defined password length validation为6作为最小的，但在测试设置，created the user与password: 'pies'。因此，你让所有的错误和失败：

FAIL["test_schould_be_valid", UserTest, 0.6801217989996076] 
test_schould_be_valid#UserTest (0.68s) 
    Expected false to be truthy. 
    test/models/user_test.rb:9:in `block in <class:UserTest>'

要解决所有的错误，你需要在UserTest#setup初始化有效数据的用户。在这种情况下，您只需提供一个最小长度为6的密码。
