Test: Missing Required Sections

Overview

This test project contains a pyproject.toml that is missing the required [project] section.

Test Scenario

The file completely lacks the [project] section, which is required by PEP 621:

# Missing [project] section entirely!

[build-system]
requires = ["hatchling"]
build-backend = "hatchling.build"

A valid pyproject.toml must have a [project] section with at least name and version fields.

Expected Behavior

The dependency tree builder should:

• Detect missing required sections
• Provide clear error message indicating what's missing
• List the required fields that should be present
• Example error:

  Error: Required section [project] not found in pyproject.toml
  Details: PEP 621 requires a [project] section with:
    - name: Project name
    - version: Project version
  Suggestion: Add [project] section with required fields
