如何对Rails 3应用程序的测试套件进行基准测试

I want to optimise a test suite. First I need to know where the time is being spent. As a minimun I want to know how much time is spent in each test.

我想优化测试套件。首先,我需要知道花费的时间。作为最小化,我想知道每次测试花费了多少时间。

I came across this gem https://github.com/timocratic/test_benchmark but is no longer maintained.

我遇到了这个宝石https://github.com/timocratic/test_benchmark但不再维护了。

Notice that my goal is to benchmark the test suite, not the application.

请注意,我的目标是对测试套件进行基准测试,而不是应用程序。

Is there any other gem that I could use?

我还可以使用其他宝石吗?

Rails
Rspec
Capybara

2 个解决方案

#1

Rspec has a minimum functionality profiler included. Have you looked at it? (blog post tutorial for rspec1 but still valid for rspec2)

Rspec包含最小功能分析器。你看过了吗? (rspec1的博客文章教程,但对rspec2仍然有效)

Basically, if you specify -p then you get a list of the slowest 10 tests.

基本上,如果指定-p,则会获得最慢的10个测试的列表。

#2

Are you familiar with the unix time command? If you're just looking to see how long your test suite took to run you can just prepend the time commmand:

你熟悉unix time命令吗?如果您只是想看看测试套件运行了多长时间,您可以先添加时间命令:

time rake spec

After your rspec output you should see something like

在您的rspec输出后,您应该看到类似的东西

Finished in 5.31 seconds
195 examples, 0 failures, 27 pending

real    0m26.580s
user    0m14.085s
sys     0m2.168s

Of course, this is assuming you're on a *nix platform :-)

当然,这是假设你在* nix平台上:-)
