Create Open Source "Eval" Suite

[handstandsam]

We currently don't have an open source "Eval" suite to verify basic interactions. There is a test suite that is not public, but it would be good to create a public test suite to ensure evaluations are run on open source changes.

This change relies on #48 being done first.

Examples:

Level 1 - Basic Screen Interaction

• Tap on UI elements
• Verify that a string exists or does not exist on screen
• Enter text into a text field
• Verify up to 2-3 commands in a prompt

Level 2 - Screen Navigation and Basic Logic

• Manipulate the correct screen or transition to the next screen:
  • Scroll to find something in a list
  • Tap on a button (e.g., Review Sale, Charge)
• Perform basic math verifications:
  • Example: Stock quantity increases correctly after an action
• Handle use of the back button
• Navigate a ten-key (numeric keypad)
• Fail gracefully if:
  • Element is impossible to tap
  • Text is impossible to enter
• Edit existing text
• Verify up to 5 commands in a prompt

Level 3 - Complex Interaction and Timing-Based Verification

• Locate and select the correct text input field when multiple fields exist
• Navigate screens with large number of interactive elements
• Verify math or data consistency on a busy screen with many updates
• Verify up to 10 commands in a prompt
