如何让Minitest跑得更快？

Question

在一个新的Rails项目中，Minitest的运行速度很慢：

首先我设置Spring binstubs：

david$ bundle exec spring binstub --all
* bin/rake: spring inserted
* bin/rails: spring inserted

接下来，我通过Spring运行默认测试（navigation_test.rb）：

david$ time bundle exec spring rake test
Run options: --seed 32313

# Running:

.

Finished in 0.003368s, 296.9121 runs/s, 296.9121 assertions/s.

1 runs, 1 assertions, 0 failures, 0 errors, 0 skips

real    0m5.171s
user    0m0.581s
sys     0m0.098s

接下来的运行速度略快，但仍然很慢（大约3秒）：

david$ time bundle exec spring rake test
Run options: --seed 48522

# Running:

.

Finished in 0.003506s, 285.2253 runs/s, 285.2253 assertions/s.

1 runs, 1 assertions, 0 failures, 0 errors, 0 skips

real    0m3.159s
user    0m0.579s
sys     0m0.088s

如果我在没有捆绑器的情况下再次运行它，它会更快一些：

david$ time spring rake test
Run options: --seed 55025

# Running:

.

Finished in 0.003413s, 292.9974 runs/s, 292.9974 assertions/s.

1 runs, 1 assertions, 0 failures, 0 errors, 0 skips

real    0m2.677s
user    0m0.087s
sys     0m0.032s

任何使用Minitest + Spring的人？如何让它跑得更快？

使用Rails 4.1.1

Answer 1

设置spring和binstub后，没有理由继续调用bundler。试试这个：

$ time bin/rake test
