Epic: #21
Story Points: 8

SO THAT I can edit a previous calculation

Acceptance Criteria

GIVEN I am in the CLI mode
WHEN I press the Up arrow key
THEN the current input will cycle backward through the history of the current session

GIVEN I am on the CLI mode
WHEN I press the Down arrow key
THEN the current input will cycle forward through the history of the current session

Subtasks

  • Save history
  • Cycle history function
  • Update tests
  • Update documentation

Test Plan

Generated test plan for #24. Fill in Actual Results and Notes during testing.

Test Plan: #24 — AS a user, I want to be able to cycle the current session's history

Issue: #24
Generated: 2026-06-29
Milestone: 0.1.0

Summary

Verify that interactive CLI mode maintains a per-session input history and lets the user recall prior expressions with the Up and Down arrow keys to edit and re-run previous calculations.

Test Cases

Id Description Expected Results Actual Results Notes
24-0001 Start interactive CLI (calculator cli). Enter and submit 2 + 3, then 10 - 4. At a new prompt, press Up once Prompt shows 10 - 4 Acceptance criterion — Up recalls most recent entry
24-0002 Continuing from 24-0001, press Up again Prompt shows 2 + 3 Up cycles further back in history
24-0003 Continuing from 24-0002, press Down once Prompt shows 10 - 4 Acceptance criterion — Down cycles forward
24-0004 Continuing from 24-0003, press Down again Prompt shows an empty input line (or latest/new entry position) Down reaches the end of history
24-0005 Start a fresh interactive session. Enter and submit three expressions in order: 1 + 1, 2 + 2, 3 + 3. Press Up repeatedly until history stops changing History cycles backward through 3 + 3, then 2 + 2, then 1 + 1 in order Multi-entry backward traversal
24-0006 From the oldest recalled entry in 24-0005, press Down repeatedly until history stops changing History cycles forward back through 2 + 2, then 3 + 3, then empty/latest position Multi-entry forward traversal
24-0007 Enter and submit 5 * 2. Press Up to recall 5 * 2, change it to 5 * 3, and submit Result shows = 15 Recalled expression can be edited and re-run
24-0008 Enter and submit 4 + 4. Press Up to recall it, then press Enter without editing Result shows = 8 again Recalled expression can be re-submitted unchanged
24-0009 In one session, enter and submit 7 - 1. Type quit and exit. Start a new interactive session and press Up at the prompt No prior expression is recalled; history is empty for the new session History is session-scoped only
24-0010 At a fresh prompt with no submitted expressions yet, press Up and Down Input line remains empty; no errors or crashes Empty history edge case
24-0011 Submit 2 + 3, press Enter on an empty line twice, then submit 4 + 5. Press Up once Prompt shows 4 + 5, not a blank line Empty submissions are not stored in history
24-0012 Submit an invalid expression such as 2 +, then submit a valid expression 3 + 3. Press Up once Prompt shows 3 + 3 Only meaningful submitted inputs are recalled
24-0013 Submit 2 + 3, then type quit and exit. Start a new session, submit one expression, and press Up Only the expression from the new session is recalled Prior session history is not persisted
24-0014 Run calculator cli "2 + 3" (single-expression mode, non-interactive) Expression evaluates and exits; arrow-key history is not applicable Out of scope — interactive mode only
