**Primary Purpose:**
Test utility file for exploring debugpy's breakpoint validation messages across different line types (comments, blank lines, executable code, docstrings).
**Structure & Key Elements:**
- **Module-level variable:** `x = 10` (L5) - simple assignment for testing
- **test_function()** (L12-18) - basic function with docstring (L13-16) and executable content (L17-18)
- **Main execution block** (L22-25) - demonstrates function call and output
- **Strategic comments throughout** - placed on various line types to test debugpy behavior
**Testing Strategy:**
The file systematically tests breakpoint placement on:
- Comment-only lines (L4, L7, L8, L10, L21, L27)
- Blank lines (L11, L20)
- Executable statements (L5, L17, L18, L23, L24, L25)
- Function definitions (L12)
- Docstring content (L13-16)
- Main guard (L22)
**Dependencies:**
None - pure Python test file with no external imports.
**Notable Patterns:**
- Extensive inline comments indicating line numbers for precise breakpoint testing
- Mix of indented and non-indented comments to test various scenarios
- Comment at L28 suggests testing breakpoints beyond file boundaries (line 100)
- Simple, minimal code to isolate debugpy message behavior
