Added ConstantsTests to verify Normalize behavior for EnvelopeSigningType, including handling of valid and out-of-range enum values using NUnit test cases. Ensures normalization logic works as expected.
All test files and utilities now use the EnvelopeGenerator.Tests.Application namespace for improved organization and clarity. No functional changes were made; updates are limited to namespaces and using directives. This makes it explicit that these are application-level tests and related helpers.
Refactored DocSignedNotificationTests to use typed repository
retrieval and explicit service resolution for PsPdfKitAnnotation.
Added a Services property to TestBase for easier access to
IServiceProvider. These changes improve clarity and robustness
of test dependency management.
Refactored Fake.cs to configure both in-memory and SQL Server
database contexts for testing, using the "Default" connection
string from configuration. Added detailed EF logging and SQL
executor setup. In TestBase.cs, fixed Setup to use the correct
repository instance for seeding email templates.
Changed test file namespaces from EnvelopeGenerator.Tests.Application to EnvelopeGenerator.Tests for consistency. Updated DigitalData.Core.Abstraction.Application package from 1.4.0 to 1.6.0 to incorporate latest improvements.
