Prevent Automatic Dosing with Future Glucose

[marionbarker]

This is a work-in-progress PR is in response to Issue #1890.

Configuration

• Test phone configured with future glucose and dosing strategy set to automatic bolus.
• Running dev, phone automatically boluses every 5 minutes, creating undesirable levels of IOB.
• With commit (updated to) fffcf50 of this branch, tested that the future glucose is detected and automated dosing stops

Display to User:

• Loop goes red over next 15 minutes, but need to add a better alerting system
• Tapping on glucose leads to the CGM
• Main screen continues to show the future glucose value (not CGM value)
• Tapping on bolus shows no recommendation with the new "Glucose in Future: Check for data in the future on phone" warning
• Tapping on meal entry allows the meal entry, but meal bolus screen is set for Save without Bolusing (no recommended bolus) with Glucose in Future warning
• In both cases, can bolus successfully if bolus value is added

Edited to change figure to that displayed with commit: ffbdc46

Debug log message:

Updated - not sure about translation request.
Edited original comment with updated figure.

Tests all passed, but I wonder if one should be added to: LoopTests/ViewModels/BolusEntryViewModelTests.swift

[marionbarker]

Added two tests to LoopTests/ViewModels/BolusEntryViewModelTests.swift.

Just noticed a typo, and made an optional name change recommendation.

[marionbarker]

All test cases succeeded in Xcode.
Built and tested on test phone (after last changes), commit 3038bc7.

• Saved carbs with no bolus

  • It was not planned, but glucose was below low end of correction range, therefore no autobolus, which is expected behavior
  • Lowered low end of correction range and modified simulated CGM entry so Loop should give an autobolus and it did

• At 15:57, add single glucose 13 minutes in the future (16:10)

  • Main screen shows the glucose, no trend is visible
  • Got automatic dose at 15:58, might have been 15:58 by the time I hit save on glucose in health
  • Invalid Future Glucose when tap on Manual Bolus until time is 16:05
  • Next automatic dose given when next CGM reading comes in 16:06

Thanks!
