The main aim of the whole exercise is to have a comprehensive set of tests, and no false positives. --- core/spec/models/spree/tax_rate_spec.rb | 184 +++--------------------- 1 file changed, 18 insertions(+), 166 deletions(-) diff --git a/core/spec/models/spree/tax_rate_spec.rb b/core/spec/models/spree/tax_rate_spec.rb index 1b3849a1b5e..a2d57b9358f 100644 --- a/core/spec/models/spree/tax_rate_spec.rb +++ b/core/spec/models/spree/tax_rate_spec.rb @@ -557,6 +557,19 @@ it 'has 15% additional tax' do expect(line_item.additional_tax_total).to eq(3) end + + it "should delete adjustments for open order when taxrate is deleted" do + new_york_books_tax.destroy! + federal_books_tax.destroy! + expect(line_item.adjustments.count).to eq(0) + end + + it "should not delete adjustments for complete order when taxrate is deleted" do + order.update_column :completed_at, Time.now + new_york_books_tax.destroy! + federal_books_tax.destroy! + expect(line_item.adjustments.count).to eq(2) + end end # This is a fictional case for when no taxes apply at all. @@ -609,177 +622,16 @@ end end end - end - end - - context 'old tests' do - before do - @country = create(:country) - @zone = create(:zone, :name => "Country Zone", :default_tax => true, :zone_members => []) - @zone.zone_members.create(:zoneable => @country) - @category = Spree::TaxCategory.create :name => "Taxable Foo" - @category2 = Spree::TaxCategory.create(:name => "Non Taxable") - @rate1 = Spree::TaxRate.create( - :amount => 0.10, - :calculator => Spree::Calculator::DefaultTax.create, - :tax_category => @category, - :zone => @zone - ) - @rate2 = Spree::TaxRate.create( - :amount => 0.05, - :calculator => Spree::Calculator::DefaultTax.create, - :tax_category => @category, - :zone => @zone - ) - @order = Spree::Order.create! - @taxable = create(:product, :tax_category => @category) - @nontaxable = create(:product, :tax_category => @category2) - end - - context "not taxable line item " do - let!(:line_item) { @order.contents.add(@nontaxable.master, 1) } - - it "should not create a tax adjustment" do - Spree::TaxRate.adjust(@order.tax_zone, @order.line_items) - expect(line_item.adjustments.tax.charge.count).to eq(0) - end - - it "should not create a refund" do - Spree::TaxRate.adjust(@order.tax_zone, @order.line_items) - expect(line_item.adjustments.credit.count).to eq(0) - end - end - context "taxable line item" do - let!(:line_item) { @order.contents.add(@taxable.master, 1) } - - context "when price includes tax" do - before do - @rate1.update_column(:included_in_price, true) - @rate2.update_column(:included_in_price, true) - Spree::TaxRate.store_pre_tax_amount(line_item, [@rate1, @rate2]) - end - - context "when zone is contained by default tax zone" do - it "should create two adjustments, one for each tax rate" do - Spree::TaxRate.adjust(@order.tax_zone, @order.line_items) - expect(line_item.adjustments.count).to eq(1) - end - - it "should not create a tax refund" do - Spree::TaxRate.adjust(@order.tax_zone, @order.line_items) - expect(line_item.adjustments.credit.count).to eq(0) - end - end - - context "when order's zone is neither the default zone, or included in the default zone, but matches the rate's zone" do - before do - # With no zone members, this zone will not contain anything - # Previously: - # Zone.stub_chain :default_tax, :contains?
