Rails - Test validation of enum fields
Your migration could be the issue, it should look something like:
t.integer :type, default: 1
You may also consider testing this another way.
Maybe more like:
it "validates the category" do
expect(invoice with category fee).to be_valid
end
Try this:
it { should validate_inclusion_of(:category).in_array(%w[sale sale_with_tax fees lease tax_free other payroll].map(&:to_sym)) }
Additionally, for code-cleanup, try putting the valid categories/types in a corresponding constant. Example:
class Invoice < ActiveRecord::Base
INVOICE_CATEGORIES = [:sale, :sale_with_tax, :fees, :lease, :tax_free, :other, :payroll]
enum category: INVOICE_CATEGORIES
end
Using Shoulda matchers we can use the following to test the enum
it { should define_enum_for(:type).with([:receivable, :payable]) }
it { should define_enum_for(:category).
with(:sale, :sale_with_tax, :fees, :lease, :tax_free, :other, :payroll) }
