Hi Team, I was looking forward to contributing to the Discourse project, and I noticed that your RSpec tests load in 0s! Are there any tips on how to reduce that time, please? In a project of mine, it’s around 30s !

What command did you run? What happened? What did you expect to happen? [圖片] Hanaffi: Are there any tips on how to reduce that time, please? In a project of mine, it’s around 30s ! You say that the time is zero, but you want it less than zero? The amount of time your project takes has no bea…

No, I was looking forward to learn how you made it, please. I want to do the same on my project

>You say that the time is zero, but you want it less than zero? I have my own project which is taking 30s and I want to reduce that time for my own rails project, so Im using this as a learning opportunity to know how Discourse team reduced their spec files loading to zero.

I think that might be a side-effect of using parallel_tests . The process which is writing the output doesn’t actually load any tests itself. Instead, it spins up multiple worker processes to run the tests.

I see, thanks so much! Do you think using spring in CI is good idea?

Rspec 加载时间为零？！

您运行了什么命令？发生了什么？您期望发生什么？

您说时间是零，但您希望它小于零？您的项目花费的时间与 Discourse（一个包含数千个测试的非常大的项目）花费的时间无关。
