Hi all,
I am following the Agile Rails book and have a problem with unit
testing. Here is my products test file:
require File.dirname(FILE) + ‘/…/test_helper’
class ProductTest < Test::Unit::TestCase
fixtures :products
def setup
@product = Product.find 1
end
def test_load_in_db
assert_kind_of Product, @product
assert_equal 29.95, @product.price
end
def test_destroy
@product.destroy
assert_raise(ActiveRecord::RecordNotFound) { Product.find
@product.id }
end
end
According to the book this should work, as different tests are not
dependent on each other, e.g. the destroy test should be independent
of the load_in_db test. I do howeveg get this after running the test:
:!ruby test/unit/product_test.rb
Loaded suite test/unit/product_test
Started
.E
Finished in 0.259161 seconds.
- Error:
test_load_in_db(ProductTest):
ActiveRecord::RecordNotFound: Couldn’t find Product with ID=1

2 tests, 1 assertions, 0 failures, 1 errors
If I remove the destroy test everything works as expected?
Any ideas as to why this is happening?
Many thanks in advance,
Nicky
