问题描述

我一直在尝试在我最近负责的 Rails 应用程序中运行真实"单元测试 mac_test.rb.它看起来像这样:

I've been trying to run a "truth" unit test, mac_test.rb in the Rails app I've recently been put in charge of. It looks like this:

    require 'test_helper'

    class MacTest < ActiveSupport::TestCase
      # Replace this with your real tests.
      test "the truth" do
        assert true
      end
    end

我已经运行了 rake db:test:prepare 并且我正在尝试使用 ruby -I test test/unit/mac_test.rb 运行测试.

I've run rake db:test:prepare and I'm trying to run the test using ruby -I test test/unit/mac_test.rb.

但是，我得到以下缩写的错误输出:

However, I get the following abbreviated error output:

    Loaded suite test/unit/mac_test
    Started
    EEEEEEEEEEEEEEE
    Finished in 0.377261 seconds.

      1) Error:
    test_datas(ActionController::IntegrationTest):
    ActiveRecord::StatementInvalid: SQLite3::SQLException: no such table: vendors: DELETE FROM "vendors" WHERE 1=1


      2) Error:
    testjigs(ActionController::IntegrationTest):
    ActiveRecord::StatementInvalid: SQLite3::SQLException: no such table: vendors: DELETE FROM "vendors" WHERE 1=1


      3) Error:
    test_datas(ActionController::TestCase):
    ActiveRecord::StatementInvalid: SQLite3::SQLException: no such table: vendors: DELETE FROM "vendors" WHERE 1=1

    <more errors here>

    15 tests, 0 assertions, 0 failures, 15 errors

所有 15 个错误都与前三个类似 - 他们抱怨缺少供应商表.供应商显然曾经存在 - 有一些像 vendor_helper 这样的剩余文件，并且在 routes.rb 文件中还有一个 map.resources :vendor.我删除了旧的供应商文件并删除了 map.resources :vendor 行.

All of the 15 errors are similar to the first three - they complain about a missing vendors table. Vendor apparently used to exist - there were some leftover files like vendor_helper and there was also a map.resources :vendor in the routes.rb file. I've deleted the old vendor files and deleted the map.resources :vendor line.

所以没有模型、视图、控制器、测试、数据库表或任何命名供应商/供应商的东西.使用 TextMate 在项目(不区分大小写)中搜索供应商"，只有一次出现供应商"不在评论、日志文件、自述文件或 boot.rb 文件中，而且是在 Capfile 中.(我认为这不会影响测试?)

So there is no model, view, controller, test, database table or anything that named vendor/vendors. Using TextMate to search the project (case-insensitive) for "vendor", there was only one occurrence of "vendor" that wasn't in a comment, a log file, the README, or the boot.rb file, and that was in the Capfile. (Which I don't think should affect the tests?)

我已经尝试使用 rake db:reset 来查看它是否是一些奇怪的数据库问题，但它仍然爆炸.

I've tried using rake db:reset to see if it was some weird database thing, but it's still exploding.

如果我尝试使用 rake test:units --trace，(只是为了获取跟踪，我不知道如何通过单个测试获取跟踪)我得到了缩写输出:

If I try to use rake test:units --trace, (just to get the trace, I don't know how to get the trace with the individual test) I get the abbreviated output:

我不知道如何让它不爆炸.谁能帮我找到一种方法让 Rails 意识到不应该再有任何供应商"?

I'm at a loss for how to get this to not explode. Can anyone help me find a way to get Rails to realize that there should no longer be any "vendors"?

我使用的是 Rails 2.3.2 和 ruby​​ 1.8.7 (2009-06-12 patchlevel 174) [i686-darwin9.7.0]

推荐答案

检查测试文件夹中是否有名为 vendor.yml 的夹具文件.如果它在那里并且您没有 vendor 表，您将收到这些错误，因为 Rails 在默认情况下会尝试使用该文件中的数据填充您的 vendor 表.

Check the test folder for a fixture file called vendors.yml. If it's there and you don't have a vendors tabler, you'll get those errors because Rails is, by default, trying to populate your vendors table with data from that file.
