Dependency updates:

• Upgraded several NuGet package references in Cake.MsDeploy.Tests.csproj, including Cake.Core and Cake.Testing to version 5.1.0, Microsoft.NET.Test.Sdk to 18.0.0, and xunit.runner.visualstudio to 3.1.5.

Test code refactoring and improvements:

• Refactored test fixture setup in multiple test methods within MsDeployRunnerTests.cs to use object initializer syntax, improving readability and consistency. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11]
• Added missing commas and fixed collection initializations in test data and settings objects for clarity and correctness. [1] [2] [3] [4]

Code style and correctness fixes:

• Made minor code style improvements, such as removing extra blank lines and correcting argument names in assertions in test files. [1] [2] [3] [4] [5] [6]
• Updated nullability handling in test assertions to use the null-forgiving operator (null!) for clarity and to avoid warnings. [1] [2] [3] [4]

Project structure:

• Added a .props folder in the solution file to include configuration files like .editorconfig, .gitattributes, and .gitignore.
