Release Notes

## [1.1.1-preview0001] - 2025-10-04

### Added

- `Assert-ObjectProperty`
- Added parameter `NoTypeCheck` to opt-in for lenient type checking, allowing
   PowerShell type coercion when comparing values.
- Added private functions:
- `Get-TypeName` - Gets the full type name of a value as a string, or 'null'
   if the value is null.
- `New-AssertionError` - Creates a Pester assertion error record with optional
   'because' reasoning to standardize error creation across assertion commands.
- `Test-ObjectHasMethod` - Tests whether an object has a specified method,
   supporting various object types including PSCustomObjects and .NET objects.
- `Test-ObjectHasProperty` - Tests whether an object has a specified property,
   supporting hashtables, PSCustomObjects, and .NET objects.
- `Test-ObjectType` - Tests whether two values have the same type for strict
   type checking in assertion commands.
- `Test-ValueEquality` - Tests whether two values are equal, supporting both
   scalar values and arrays with structural comparison.

### Changed

- `Assert-ObjectProperty`
- Added parameter `Each` to opt-in for element-by-element checking when
   passing arrays via pipeline or parameter. Without this parameter, the
   command now checks properties on the array object itself (e.g., `Count`,
   `Length`).
- Improved error messages to distinguish between type mismatches and value
   mismatches when strict type checking is enabled.
- `Assert-ObjectMethod`
- Added parameter `Each` to opt-in for element-by-element checking when
   passing arrays via pipeline or parameter. Without this parameter, the
   command now checks methods on the array object itself.
- `Assert-BlockString`
- Refactored to use the `New-AssertionError` private function for consistent
   error handling across all assertion commands.
- `New-AssertionError`
- Updated to follow Pester's error message pattern by inserting the `Because`
   clause before `, but` in error messages (e.g., "Expected \<value\>, because
   \<reason\>, but got \<actual\>").
- Localized strings have been reorganized to consolidate common reusable words
(like "because", "actual", and "expected") into a dedicated "Common localized
strings" section with a consistent `Common_Word*` naming pattern, reducing
duplication across command-specific string keys.
