ruby-on-rails – 为什么我的Rails测试没有看到我的内存中SQLite

我在database.yml中的数据库配置如下所示：

test:
  adapter: sqlite3
  database: ":memory:"
  encoding: utf8
  verbosity: quiet

我还按照建议创建了初始化程序：

def in_memory_database?
  Rails.env == "test" and
    ActiveRecord::Base.connection.class == ActiveRecord::ConnectionAdapters::SQLiteAdapter ||
      ActiveRecord::Base.connection.class == ActiveRecord::ConnectionAdapters::SQLite3Adapter and
    Rails.configuration.database_configuration['test']['database'] == ':memory:'
end

if in_memory_database?
  ActiveRecord::Schema.verbose = false
  puts "creating sqlite in memory database"
  load "#{Rails.root}/db/schema.rb"
end

我的所有测试都失败了,因为无法加载灯具,您可以看到：

creating sqlite in memory database
Loaded suite test/unit/vendor_appliance_test
Started
E
Finished in 0.070079 seconds.

  1) Error:
test_the_truth(VendorApplianceTest):
ActiveRecord::StatementInvalid: Could not find table 'advertisers'


1 tests,0 assertions,0 failures,1 errors

初始化程序确实加载了数据库(正如您可以从输出的第一行看到的那样),但由于某种原因,模式对于测试是不可见的,因为它看起来在错误的位置或因为它已被时间擦除测试开始了.

有人见过这个吗？
