# Documentation: DatabaseUnitTesting.Properties.Settings
|
||
|
|
|
||
|
|
## 1. Purpose
|
||
|
|
|
||
|
|
This module is an auto-generated settings class that provides strongly-typed access to application configuration values for the `DatabaseUnitTesting` project. It exists to centralize configuration management for database unit testing, specifically storing connection parameters, database names, and snapshot identifiers. The class is generated by Visual Studio's `SettingsSingleFileGenerator` tool and serves as the configuration layer between the unit test code and the underlying `.settings` file.

## 2. Public Interface
|
||
|
|
|
||
|
|
### `Settings` (sealed partial class)
|
||
|
|
**Inherits from:** `global::System.Configuration.ApplicationSettingsBase`
|
||
|
|
|
||
|
|
| Member | Signature | Scope | Description |
|
||
|
|
|--------|-----------|-------|-------------|
|
||
|
|
| `Default` | `public static Settings Default { get; }` | Static | Returns the singleton default instance of the `Settings` class, synchronized for thread-safe access. |
|
||
|
|
| `ConnectionString` | `public string ConnectionString { get; }` | Application-scoped | Returns the database connection string for the unit test database. Read-only. Default value points to `FAJITA\DEV_SQL` server with `DataPRO_UnitTest` catalog. |
|
||
|
|
| `DBName` | `public string DBName { get; set; }` | User-scoped | Gets or sets the database name. Default value is `"DataPRO_UnitTest"`. |
|
||
|
|
| `DBSnapshot` | `public string DBSnapshot { get; set; }` | User-scoped | Gets or sets the database snapshot name. Default value is `"DataPRO_UnitTestSnapshot"`. |

## 3. Invariants
|
||
|
|
|
||
|
|
- **Auto-generated constraint**: This file is machine-generated by `Microsoft.VisualStudio.Editors.SettingsDesigner.SettingsSingleFileGenerator` version `17.10.0.0`. Manual modifications will be lost upon regeneration.
|
||
|
|
- **Singleton pattern**: The `defaultInstance` field is created once via `Synchronized()` and returned through the `Default` property.
|
||
|
|
- **Scope immutability**: `ConnectionString` is application-scoped (read-only at runtime); `DBName` and `DBSnapshot` are user-scoped (read/write).
|
||
|
|
- **Type safety**: All settings are typed as `string`; accessors perform explicit casts from the underlying settings dictionary.

## 4. Dependencies
|
||
|
|
|
||
|
|
### This module depends on:
|
||
|
|
- `System.Configuration.ApplicationSettingsBase` - Base class providing settings management infrastructure
|
||
|
|
- `System.Configuration.ApplicationScopedSettingAttribute` - Attribute for application-level settings
|
||
|
|
- `System.Configuration.UserScopedSettingAttribute` - Attribute for user-level settings
|
||
|
|
- `System.Configuration.SpecialSettingAttribute` - Marks `ConnectionString` as a special connection string type
|
||
|
|
- `System.Configuration.DefaultSettingValueAttribute` - Provides default values for each setting
|
||
|
|
- `System.Runtime.CompilerServices.CompilerGeneratedAttribute` - Indicates tool-generated code
|
||
|
|
- `System.CodeDom.Compiler.GeneratedCodeAttribute` - Metadata about the code generator
|
||
|
|
|
||
|
|
### What depends on this module:
|
||
|
|
- **Inferred**: Any code within the `DatabaseUnitTesting` project that accesses configuration values via `Settings.Default`.

## 5. Gotchas
|
||
|
|
|
||
|
|
1. **Hardcoded credentials in source control**: The `ConnectionString` default value contains a plaintext SQL Server `sa` password (`!!QQAAZZxxssww22`). This is a significant security risk and should be moved to a secure configuration mechanism (e.g
