❔ ConfigureTestServices not overriding connection string value :(

Hi! I'm so lost as to why this isn't working. Currently the RemoveDbContext removes the service as expected. And I get no exceptions from re-adding with the new config. I have debugged that if I change my development appsettings to the hardcoded connection string from the created container it works fine. But as soon as I change dev connection string back to what it is I get db login issues/couldn't establish connection issues. So it must not be overriding the config. Any ideas on how I can fix this?

public class JobbyHttpApiFactory : WebApplicationFactory<Program>, IAsyncLifetime
{
    public string JobbyDbConnectionString { get; set; } = string.Empty;
    private readonly MsSqlContainer _mssqlContainer;
    private readonly IConfiguration _configuration;
    public HttpClient HttpClient { get; private set; } = null!;

    public async Task InitializeAsync()
    {
        await _mssqlContainer.StartAsync();
        
        JobbyDbConnectionString = _mssqlContainer.GetConnectionString();
    }

    public new async Task DisposeAsync()
    {
        ...
    }
    
    protected override void ConfigureWebHost(IWebHostBuilder builder)
    {
        builder.ConfigureTestServices(services =>
        {
            services.RemoveDbContext<JobbyDbContext>();
            
            services.AddDbContext<JobbyDbContext>(options =>
            {
                options.UseSqlServer(_mssqlContainer.GetConnectionString());
            });

            services.EnsureDbCreatedAsync<JobbyDbContext>().ConfigureAwait(true);
        });
    }
}

public class JobbyHttpApiFactory : WebApplicationFactory<Program>, IAsyncLifetime
{
    public string JobbyDbConnectionString { get; set; } = string.Empty;
    private readonly MsSqlContainer _mssqlContainer;

    public HttpClient HttpClient { get; private set; } = null!;

    public async Task InitializeAsync()
    {
        await _mssqlContainer.StartAsync();
        
        JobbyDbConnectionString = _mssqlContainer.GetConnectionString();
    }

    public new async Task DisposeAsync()
    {

    }

        {
            services.RemoveDbContext<JobbyDbContext>();
            
            services.AddDbContext<JobbyDbContext>(options =>
            {
                options.UseSqlServer(_mssqlContainer.GetConnectionString());
            });

            services.EnsureDbCreatedAsync<JobbyDbContext>().ConfigureAwait(true);
        });
    }
}

    public static void RemoveDbContext<T>(this IServiceCollection services) where T : DbContext

        var descriptor = services.SingleOrDefault(d => d.ServiceType == typeof(T));
        if (descriptor != null)
        {
            services.Remove(descriptor);
        }
    }

Don't just remove the context, you must also remove the context options That's what actually contains your configured setup

Nickolaki•12mo ago

Ah damn, I had thought it was something like this. Will give it a go boss. What type is context options? DbContextOptions or something?

Pobiega•12mo ago

Yup

Nickolaki•12mo ago

Cheers boss Will let you know how it goes 🤣🤣

Pobiega•12mo ago

It's whatever type your context constructor takes in

Working! Thank you bro

        var dbContextOptionsService = services.SingleOrDefault(
            d => d.ServiceType ==
                 typeof(DbContextOptions<T>));
        
        if (dbContextOptionsService != null)
        {
            services.Remove(dbContextOptionsService);
        }

        
        var dbContextService = services.SingleOrDefault(d => d.ServiceType == typeof(T));
        if (dbContextService != null)
        {

        }
    }

        if (dbContextOptionsService != null)
        {
            services.Remove(dbContextOptionsService);
