* Remove xunit dependency from testdriver
* swap expected/actual as needed
* Convert Test.Common to nunit
* port hosting unit tests to nunit
* port batchparser integration tests to nunit
* port testdriver.tests to nunit
* fix target to copy dependency
* port servicelayer unittests to nunit
* more unit test fixes
* port integration tests to nunit
* fix test method type
* try using latest windows build for PRs
* reduce test memory use
* Add LanguageFlavorNotification handling and refactor LanguageService
- Added new notification handler for language flavor changed
- Refactored the LanguageService so that it no longer relies on so many intertwined static calls, which meant it was impossible to test without modifying the static instance. This will help with test reliability in the future, and prep for replacing the instance with a service provider.
* Skip if not an MSSQL doc and add test
* Handle definition requests
* Fix diagnostics handling
The goal of this make sure that test code is correctly organized to ensure that test suites aren't dependent on each other.
* UnitTests get their own project now (renaming Microsoft.SqlTools.ServiceLayer.Test to Microsoft.SqlTools.ServiceLayer.UnitTests) which is about 90% of the changes to the files.
* IntegrationTests no longer depends on UnitTests, only Test.Common
* Any shared components from TestObjects that spins up a "live" connection has been moved to IntegrationTests Utility/LiveConnectionHelper.cs
* The dictionary-based mock file stream factory has been moved to Test.Common since it is used by UnitTests and IntegrationTests
* Added a overload that doesn't take a dictionary for when we don't care about monitoring the storage (about 90% of the time)
* The RunIf* wrapper methods have been moved to Test.Common
* OwnerUri and StandardQuery constants have been moved to Test.Common Constants file
* Updating to latest SDK version available at https://www.microsoft.com/net/core#windowscmd
* Moving unit tests to unit test folder
* Changing namespaces to UnitTests
* Moving some constants and shared functionality into common project, making the UnitTests reference it
* Unit tests are working!
* Integration tests are working
* Updating automated test runs
* Fixing one last broken unit test
* Exposing internals for other projects
* Moving edit data tests to UnitTest project
* Applying refactor fixes to unit tests
* Fixing flaky test that wasn't awaiting completion
