Error: SimpleCov failed with exit 1

[John Cowan]

Hey all

I'm upgrading a rails app from rails 4.2 to 5.0.  It is using ruby 2.6.4.

When I run my spec tests, I get the error: SimpleCov faild with exit 1.   I cannot find any info on this using Google.  I've read through the documentation for the gem, but I cannot find any info that helps me with what is causing this or how to fix it.

Gemfile:

    `gem 'rails', '~> 5.0'

I also made these changes in Gemfile to get bundle update rails to work.

-gem 'sass-rails', '~> 4.0.3'
+gem 'sass-rails'
-gem 'coffee-rails', '~> 4.0.0'
+gem 'coffee-rails'

----------------------------

Gemfile.lock

simplecov (0.18.5)

  docile (~> 1.1)

  simplecov-html (~> 0.11)

simplecov-html (0.12.2)

----------------------------

To quiet a couple of un-related deprecation warnings, I had to make changes to these files

config/environments/production.rb

-  config.serve_static_files = false
+  config.public_file_server.enabled = false

config/environments/staging.rb
-  config.serve_static_files = false
+  config.public_file_server.enabled = false

config/environments/test.rb
-  config.serve_static_files = true
+  config.public_file_server.enabled = true
 
-  config.static_cache_control = "public, max-age=3600"
+  config.public_file_server.headers = { 'Cache-Control' => 'public, max-age=3600' }

to be rendered by your app:

Example:
  //= link_tree ../images
  //= link_directory ../javascripts .js
  //= link_directory ../stylesheets .css
and restart your server

----------------------------

I do not think the manifest.js output is related, but left it in just in case it is a clue to anyone.

Lines 18 - 21 are files we wrote (not created by ruby/rails).

----------------------------

I do not know of any log files that might contain any clues.  I've read many threads via Google, but did not find any with my actual topic.

Any help would be greatly appreciated.

Thank you.

I ended up blowing away my Gemfile.lock and running bundle install again and that did the trick.  I think I must have ran a `bundle update` at one point and that updated the simplecov gem to the higher version.

Thank you for the input on the manifest.js error.  I did add the recommended file and that solved that issue.

Now, on to some feature specs that no longer pass.

Thanks again,

Cheers!
