YAML with erb is not parsing

Question

Why this yaml file won\'t parse?

---
<% sensor_types = YAML.load_file(\'db/seed-fixtures/sensor_type.yml\') %>
<% sensor_types.each do |sensor_type|

You can't load a YAML file containing ERB like a basic YAML file. Checkout this post.

What you can do instead is (in a spec initializer or a before hook):

FIXTURE_CONFIG = YAML.load(ERB.new(File.read("#{Rails.root}/path_to_your_file.yml.erb")).result)

And then use this variable in your test.
