Question

我有一个包含以下内容的gemfile：

# frozen_string_literal: true
source "https://rubygems.org"

gem 'cucumber'
gem 'minitest', '~> 5.10', '>= 5.10.3'
gem 'minitest-focus'
gem 'minitest-reporters', '~> 1.1.9'
gem 'rspec'
...

用于加载并需要宝石的黄瓜.env文件：

require 'bundler'

Bundler.require

带有以下内容的Ruby文件：

require 'minitest/autorun'
require_relative './../../../../RubyProjects/mksta-common/common'

class VerifyApi < MiniTest::Test

  include Common

  def initialize(has_authorization)
    @has_authorization = has_authorization
  end

  def test_id_correct
    assert_equal(20, 20)
  end
end

我在尝试执行断言时收到此错误：

未定义的方法`+'代表nil：NilClass

在Assertions.rb中：

def assert_equal exp, act, msg = nil
      msg = message(msg, E) { diff exp, act }
      result = assert exp == act, msg

      if exp.nil? then
        if Minitest::VERSION =~ /^6/ then
          refute_nil exp, "Use assert_nil if expecting nil."
        else
          where = Minitest.filter_backtrace(caller).first
          where = where.split(/:in /, 2).first # clean up noise

          warn "DEPRECATED: Use assert_nil if expecting nil from #{where}. This will fail in Minitest 6."
        end
      end

      result
    end

def assert test, msg = nil
      self.assertions += 1
      unless test then
        msg ||= "Expected #{mu_pp test} to be truthy."
        msg = msg.call if Proc === msg
        raise Minitest::Assertion, msg
      end
      true
    end

错误发生在：“self.assertions + = 1”，所以我不确定“断言”的设置在哪里..

我想知道我的要求流程是否不正确，或者我是否缺少要求。或许Cucumber / Rspec正在阻碍？任何帮助将不胜感激。

好吧，问题是当您初始化VerifyApi时，您没有初始化MiniTest :: Test。因此，self.assertions为零。为了解决这个问题，您只需要在初始化函数中再添加一行

super(name)

当然，您需要在函数中添加一个参数。

Ruby Minitest assert_equal失败
