If you find tests like these, DELETE THEM IMMEDIATLY. They provide less value than
not having a test. It's better to know that this wasn't tested.

Given I have 10 dollars
When I purchase a lottery ticket for 2 dollars
Then I will have 8 dollars
And I will get a lottery ticket
And I will be congratulated for paying the mathematically challenged tax.
