关于 ruby??：为什么我在 ONE 模型上的 rspec Rails 测试需要 10 分钟？！ (Rails 3.2/rspec 2/Guard/spork)

codeneng 2023-03-28 原文

Why do my rspec Rails tests on ONE model is taking 10 minutes ?! (Rails 3.2/rspec 2/Guard/spork)

我在我的应用程序中定义了 rspec 测试，但它们需要很长时间！
在我的整个应用程序中，我在 37 分钟内运行了 438 个测试。每分钟只有 10 次测试。

我将 Guard 用于 rspec、Spork，所以我认为它应该更快。一定是出了什么问题。

例如，模型 \\'Prize\\' 的 rspec 测试需要 13 分钟进行 134 次测试。它非常慢！这是我的奖品规格：

我阅读了几篇关于如何改进时间的文章，但我想先了解为什么它会这么慢(30 分钟！)，然后我才能选择正确的测试优化技术。

似乎它大部分时间都在为您的验证生成错误消息。您可以尝试对其进行优化，但如果您正在寻找一个简单的加速，您可以只Stubbing整个过程的一部分。我只会用 "error message" Stubbing ActiveModel::Errors#generate_message，这样可以节省大量处理时间。

1	ActiveModel::Errors.any_instance.stub(:generate_message).and_return('error message')

@Alex_Siri 谢谢，你会把它放在哪个文件中？在 spec_helper.rb 中？
我会把它放在你的规范文件中的 before 块中，所以它只适用于那里

ruby-on-rails - 使用 Ruby on Rails 进行自动化测试 - 最佳实践 - 2
很好奇，就使用rubyonrails自动化单元测试而言，你们正在做什么？您是否创建了一个脚本来在cron中运行rake作业并将结果邮寄给您？git中的预提交Hook？只是手动调用？我完全理解测试，但想知道在错误发生之前捕获错误的最佳实践是什么。让我们理所当然地认为测试本身是完美无缺的，并且可以正常工作。下一步是什么以确保他们在正确的时间将可能有害的结果传达给您？最佳答案不确定您到底想听什么，但是有几个级别的自动代码库控制:在处理某项功能时，您可以使用类似autotest的内容获得关于哪些有效，哪些无效的即时反馈。要确保您的提
ruby-on-rails - rails : keeping DRY with ActiveRecord models that share similar complex attributes - 2
这似乎应该有一个直截了当的答案，但在Google上花了很多时间，所以我找不到它。这可能是缺少正确关键字的情况。在我的RoR应用程序中，我有几个模型共享一种特定类型的字符串属性，该属性具有特殊验证和其他功能。我能想到的最接近的类似示例是表示URL的字符串。这会导致模型中出现大量重复(甚至单元测试中会出现更多重复)，但我不确定如何让它更DRY。我能想到几个可能的方向...按照“validates_url_format_of”插件，但这只会让验证干给这个特殊的字符串它自己的模型，但这看起来很像重溶液为这个特殊的字符串创建一个ruby类，但是我如何得到ActiveRecord关联这个类模型
ruby-on-rails - 在 Rails 中将文件大小字符串转换为等效千字节 - 2

ruby-on-rails - Ruby net/ldap 模块中的内存泄漏 - 2
作为我的Rails应用程序的一部分，我编写了一个小导入程序，它从我们的LDAP系统中吸取数据并将其塞入一个用户表中。不幸的是，与LDAP相关的代码在遍历我们的32K用户时泄漏了大量内存，我一直无法弄清楚如何解决这个问题。这个问题似乎在某种程度上与LDAP库有关，因为当我删除对LDAP内容的调用时，内存使用情况会很好地稳定下来。此外，不断增加的对象是Net::BER::BerIdentifiedString和Net::BER::BerIdentifiedArray，它们都是LDAP库的一部分。当我运行导入时，内存使用量最终达到超过1GB的峰值。如果问题存在，我需要找到一些方法来更正我的代
ruby-on-rails - unicode 字符串的长度 - 2
在我的Rails(2.3，Ruby1.8.7)应用程序中，我需要将字符串截断到一定长度。该字符串是unicode，在控制台中运行测试时，例如'א'.length，我意识到返回了双倍长度。我想要一个与编码无关的长度，以便对unicode字符串或latin1编码字符串进行相同的截断。我已经了解了Ruby的大部分unicode资料，但仍然有些一头雾水。应该如何解决这个问题？最佳答案 Rails有一个返回多字节字符的mb_chars方法。试试unicode_string.mb_chars.slice(0,50)
ruby-on-rails - Ruby on Rails 迁移，将表更改为 MyISAM - 2
如何正确创建Rails迁移，以便将表更改为MySQL中的MyISAM？目前是InnoDB。运行原始执行语句会更改表，但它不会更新db/schema.rb，因此当在测试环境中重新创建表时，它会返回到InnoDB并且我的全文搜索失败。我如何着手更改/添加迁移，以便将现有表修改为MyISAM并更新schema.rb，以便我的数据库和相应的测试数据库得到相应更新？最佳答案我没有找到执行此操作的好方法。您可以像有人建议的那样更改您的schema.rb，然后运行:rakedb:schema:load，但是，这将覆盖您的数据。我的做法是(假设
