Add hello module with src/hello.py and tests

Add a hello module to freematters/testbed. Create src/hello.py with a function hello(name: str) -> str that returns 'Hello, !' and add tests/test_hello.py with basic tests.

Plan

• Step 1: Implement hello module with tests

Summary

Design

A single-module architecture: src/hello.py provides a hello(name: str) -> str function that returns a greeting string. No external dependencies, no error handling — the function passes through all inputs using Python f-string formatting. Tested by tests/test_hello.py with basic unit tests.

E2E Testing

E2E testing was not included in this spec — the feature is too simple to warrant agent-level testing. Unit tests provide sufficient coverage.

Where would you like to start?

1. Requirements clarification (recommended) — refine the idea through Q&A
2. Research first — investigate specific technical topics before refining requirements

[bot reply] Great, let's clarify requirements!

Q1: How should the hello() function handle edge cases like empty strings, None, or non-string inputs? Should it raise an error, return a default greeting, or just pass them through?

[jamesrxian]

Just pass them through. No special error handling needed — keep it simple.

[jamesrxian]

[bot reply] Got it — keep it simple, pass through whatever is given.

Q2: This is a very simple module. I'd recommend skipping e2e agent tests since they're slow (two agent sessions per run) and the feature is trivially testable with unit tests alone. Does that sound right, or do you want e2e coverage anyway?

[jamesrxian]

Agreed, no e2e tests needed. Unit tests are sufficient.

Rough Idea

Add a hello module to freematters/testbed. Create src/hello.py with a function hello(name: str) -> str that returns 'Hello, <name>!' and add tests/test_hello.py with basic tests.

Q1: How should the hello() function handle edge cases like empty strings, None, or non-string inputs?

A1: Just pass them through. No special error handling needed — keep it simple.

Q2: Should we include e2e (end-to-end) agent tests for this feature?

A2: No e2e tests needed. Unit tests are sufficient.

Requirements Summary

• Module: src/hello.py with a single function hello(name: str) -> str
• Behavior: Returns 'Hello, <name>!' — simple string formatting
• Edge cases: Pass through whatever is given, no special error handling
• Tests: tests/test_hello.py with basic unit tests (e.g., normal name, empty string)
• E2E tests: Not needed — too simple to warrant agent-level testing

[jamesrxian]

[bot reply] Requirements captured! Here's what we have:

• Module: src/hello.py with hello(name: str) -> str returning 'Hello, <name>!'
• Edge cases: Pass through, no error handling
• Tests: Unit tests in tests/test_hello.py
• E2E tests: Not needed

What would you like to do next?

1. Revise requirements — revisit and refine
2. Research first — investigate technical topics
3. Proceed to design — move to architecture & design
4. Fast forward — generate design, plan, and summary in one shot (no intermediate approvals)

Overview

Add a simple hello module to the freematters/testbed repository. The module provides a single function hello(name) that returns a greeting string. This is a minimal utility with no dependencies, no error handling, and straightforward unit test coverage.

Goal & Constraints

Goal:

• Provide a hello(name: str) -> str function in src/hello.py that returns 'Hello, <name>!'
• Provide unit tests in tests/test_hello.py covering basic usage and edge cases

Constraints:

• MUST NOT add any external dependencies
• MUST NOT add special error handling — pass through all inputs
• MUST NOT include e2e tests

Architecture Overview

graph LR
    A[src/hello.py] -->|tested by| B[tests/test_hello.py]

Loading

Single module, single test file. No additional components needed.

Components & Interfaces

src/hello.py

Responsibility: Provide the hello greeting function.

API Surface:

def hello(name: str) -> str:
    """Return a greeting string for the given name."""
    return f"Hello, {name}!"

tests/test_hello.py

Responsibility: Verify the hello function behaves correctly.

Test cases: See Integration Testing section below.

Data Models

No data models needed — the function takes a string and returns a string.

Integration Testing

Since this is a single-function module with no external dependencies, integration tests and unit tests are equivalent.

• Given: The hello function is imported from src.hello
  When: Called with "World"
  Then: Returns "Hello, World!"

• Given: The hello function is imported
  When: Called with "" (empty string)
  Then: Returns "Hello, !"

• Given: The hello function is imported
  When: Called with "Alice"
  Then: Returns "Hello, Alice!"

E2E Testing

Not applicable — skipped per requirements. Unit tests provide sufficient coverage for this trivial module.

Error Handling

No error handling. The function passes through whatever input it receives, relying on Python's default f-string behavior. If a non-string is passed, Python's string formatting will handle it (e.g., hello(42) → "Hello, 42!").

Checklist

Step 1: Implement hello module with tests

Depends on: none

Objective: Create the hello module and its unit tests in a single step, since the module is trivially small and the tests are tightly coupled to it.

Related Files:

• src/hello.py (create) — the hello function
• tests/test_hello.py (create) — unit tests
• pyproject.toml (read) — check for test runner config

Test Requirements (TDD — write tests first):

• Test hello("World") returns "Hello, World!"
• Test hello("") returns "Hello, !"
• Test hello("Alice") returns "Hello, Alice!"

All three test cases from design.md's Integration Testing section are covered here.

Implementation Guidance:

• Create src/hello.py with the hello(name: str) -> str function per design.md Components & Interfaces
• Create tests/test_hello.py importing from src.hello and testing all cases above
• No external dependencies, no error handling
• Run tests with pytest to verify

Next Steps

The spec is ready for implementation. The plan has 1 step: implement the hello module with tests.

[jamesrxian]

[bot reply] ## Spec Complete!

The spec is ready. How would you like to proceed?

1. Full auto — implement the spec and submit a PR without any human approvals. Spec-to-code runs in fast-forward mode and PR submission starts automatically.
2. Fast forward — proceed to implementation, but pause before starting and before creating the PR for your confirmation.
3. Stop here — keep the spec artifacts and end the workflow.

Reply with your choice (1, 2, or 3).
