In an .erb template, I want to test if a value is in an array (and if yes do something).

I thought the way to do it might me something like:

<% if @testservers.include? @fqdn %>
environment = test
<% else %>
environment = production
<% end %>

However that blows up complaining that .include is an undefined function.

It will do so if @testservers is not an array (or, more properly, if it does not have a method named "include?").  Perhaps this will do what you want:

<% if (defined? @testservers) and (@testservers.class == 'Array') and (@testservers.include? @fqdn) %>
