More readable value change testing in rspec

01 Sep 2015 Some simple but effective rspec syntax that I just learned:

expect{Object.method}.to change{Object.count}.from(0).to(1)

I think this is fairly straightforward, but essentially it just lets you test for value changes. This is basically just a clearer way of writing expectations and would replace something like this:

expect(Object.count).to eq(0)
Object.method
expect(Object.count).to eq(1)

Check the rspec docs for more details.
