Assets precompilation is run when running tests

[diaclavijo]

You can visit this project

It is an small application to show that sprockets-rails 3.1 is precompiling the assets when
the specs require them even having the configuration assets.compile = true.

This application raise an exception when the precompilation of the assets is executed. This is to
proof that assets precompilation is run when running tests that require them.

The test spec/views/welcome/index.html.erb_spec.rb just renders a view which calls
<%= stylesheet_link_tag 'index' %> .

This test fails in sprockets-rails 3.1 when trying to run the assets precompilation.
You can checkout from the commit and run specs.

But it passes in sprockets-rails 2.3 as it compiles the file on demand.
You can checkout from the commit and run specs.

I expected that if you have assets.compile = true it will never run precompilation and always
compile assets on demand.

Am I understanding something wrong here?

I may be seeing something related to this issue. I have tests failing during asset compilation following an upgrade of Rails 4.1.16 to Rails 4.2.7.1, which brings with it an upgrade of sprockets-rails from 2.3.3 to 3.1.1. My remedy thus far is to lock sprockets-rails at 2.x
