My program is really simple.

$ cat MyProject/Program.cs
using System.Reflection;
using NHSISL.LibPostalClient.Clients;
using NHSISL.LibPostalClient.Models.Brokers.LibPostal;

Console.WriteLine("Hello, World!");
var assembly = Assembly.GetExecutingAssembly().Location;
var dataFolderPath = Path.Combine(
    Path.GetDirectoryName(assembly) ?? throw new InvalidOperationException("Assembly path null"),
    @"Data"
);

var config = new LibPostalConfiguration {
    DataDirectory = dataFolderPath,
    ParserDataDirectory = dataFolderPath,
    LanguageClassifierDataDirectory = dataFolderPath
};

var libPostalClient = new LibPostalClient(config);
var inputAddress = "123 Main St";
var outputParsedAddress =
    new List<KeyValuePair<string, string>> { new("road", "main st"), new("house_number", "123"), };
var expectedParsedAddress = outputParsedAddress.ToList();

// Act
var actualParsedAddress = await libPostalClient.ParseAddressAsync(inputAddress);

foreach (var parsedAddress in actualParsedAddress)
{
        Console.WriteLine(parsedAddress.Value);
}

The unit test

$ cat LibpostalClientTests.cs
using System.Reflection;
using NHSISL.LibPostalClient.Clients;
using NHSISL.LibPostalClient.Models.Brokers.LibPostal;

namespace MyProjectTests;

public class LibpostalClientTests
{
        private readonly ILibPostalClient _libPostalClient;

        public LibpostalClientTests()
        {
                var assembly = Assembly.GetExecutingAssembly().Location;
                var dataFolderPath = Path.Combine(
                    Path.GetDirectoryName(assembly) ?? throw new InvalidOperationException("Assembly path null"),
                    @"Data"
                );

                var config = new LibPostalConfiguration {
                    DataDirectory = dataFolderPath,
                    ParserDataDirectory = dataFolderPath,
                    LanguageClassifierDataDirectory = dataFolderPath
                };

                _libPostalClient = new LibPostalClient(config);
        }

        [Test]
        public async Task GivenShortAddress_ParseAddressAsync_ReturnsExpectedResult()
        {
                // Arrange
                const string inputAddress = "123 Main St";
                var outputParsedAddress =
                    new List<KeyValuePair<string, string>> { new("road", "main st"), new("house_number", "123"), };
                var expectedParsedAddress = outputParsedAddress.ToList();

                // Act
                var actualParsedAddress = await _libPostalClient.ParseAddressAsync(inputAddress);

                // Assert
                actualParsedAddress.Should().BeEquivalentTo(expectedParsedAddress);
        }
}

Expected Behavior

The Libpost data files are copied under the MyprojectTests/bin/(Debug|Release)/net8.0 folder instead of MyProject folder.
