class Thing
def self.count
@count ||= 0

self.class.count += 1

require_relative "../test.rb"
describe Thing do
after(:example) do
puts "called"
#Thing.reset_count
end
context "using subject!" do
subject!(:thing) { Thing.new }
it "returns 1" do
expect(Thing.count).to eq(1)
end
it "returns 2" do
expect(Thing.count).to eq(2)
end
end
end
If I run the test :-
arup@linux-wzza:~/Ruby> rspec spec/test_spec.rb
.F
Failures:
1) Thing using subject! returns memoized version on first invocation
Failure/Error: expect(Thing.count).to eq(1)
expected: 1
got: 3
(compared using ==)
# ./spec/test_spec.rb:13:in `block (3 levels) in <top (required)>'
Finished in 0.00173 seconds (files took 0.13718 seconds to load)
2 examples, 1 failure
Failed examples:
rspec ./spec/test_spec.rb:11 # Thing using subject! returns memoized
version on first invocation
Now my question is how @count incremented by 3, shouldn't it be by 2 ?
