How would I configure Effort Testing Tool to mock Entity Framework's DbContext withOut the actual SQL Server Database up

wish of those help You only need that connection string because Effort needs to know where the EDMX file is.
The EDMX file contains all information required for creating an inmemory store with an identical schema you have in your database. You have to specify a connection string only because I thought it would be convenient if the user didn't have to mess with EDMX paths.
code :
public static EntityConnection CreateTransient(string entityConnectionString, IDataLoader dataLoader)
{
    var metadata = GetEffortCompatibleMetadataWorkspace(ref entityConnectionString);
    var connection = DbConnectionFactory.CreateTransient(dataLoader);
    return CreateEntityConnection(metadata, connection);
}

private static MetadataWorkspace GetEffortCompatibleMetadataWorkspace(ref string entityConnectionString)
{
    entityConnectionString = GetFullEntityConnectionString(entityConnectionString);

    var connectionStringBuilder = new EntityConnectionStringBuilder(entityConnectionString);

    return MetadataWorkspaceStore.GetMetadataWorkspace(
        connectionStringBuilder.Metadata,
        metadata => MetadataWorkspaceHelper.Rewrite(
            metadata, 
            EffortProviderConfiguration.ProviderInvariantName, 
            EffortProviderManifestTokens.Version1));
}

Update model causes interface to be removed from DbContext when using Effort with Entity Framework

I wish this helpful for you Yes, the class is defined as a partial class. Create a new file that also declares the same partial class and add your additional methods there.
As for the [Key] attribute being lost, you can try and use a MetadataType attribute and put all your meta data there.
code :
namespace Cssd.IT.PortalIntegration.DataAccess.HR.Dao
{
    using System;
    using System.Collections.Generic;
    using System.ComponentModel.DataAnnotations;

    [MetadataType(typeof(CCS_DEPT_TBL_Meta))]
    public partial class CCS_DEPT_TBL
    {
      ... Your additional constructors and methods here ...
    }
    public class CCS_DEPT_TBL_Meta
    {
        [Key]
        public string DEPTID { get; set; }    
    }
}
Shim DbContext ctor for Effort unit testing

I wish this help you (edit: I just realized this isn't actually returning the other ctor call. working on it.)
Figured it out. Simple enough if you know how to do it:
code :
        [TestMethod]
        public void Should_have_a_name_like_this()
        {
            // Arrange
            var connection = Effort.DbConnectionFactory.CreateTransient();
            ShimSolrDbContext.Constructor = context => new SolrDbContext(connection);

            // Act


            // Assert

        }
public class SomeDbContext
{
    public SomeDbContext() : base("name=Prod")
    {
    }

    // EFfort unit testing ctor
    public SomeDbContext(DbConnection connection) : base(connection, contextOwnsConnection: true) {
        Database.SetInitializer<SolrDbContext>(null);
    }
}
public class SomeRepository
{
    public void SomeMethodName()
    {
        using (var context = new SomeDbContext())
        {
            // self-contained in repository, no special params
            // and still calls the special test constructor
        }
    }
}

Any of those help The problem was that I had to specify the key for my KeyValuePair dataset.
code :
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
    modelBuilder.Entity<KeyValuePair>().HasKey(x => x.Key);
    base.OnModelCreating(modelBuilder, null);

it fixes the issue I am trying to inject a simple connection string in an ASP.NET Core 2.1 API project. , These are the two constructors on your database context type DB:
code :
public DB(DbContextOptions<DbContext> options) : base(options) { }
public DB() { }
public DB(DbContextOptions<DB> options)
    : base(options)
{ }

With these it helps If for whatever reason you need to manage transactions yourself it is much easier to use TransactionScope. It has several constructors accepting a TimeSpan parameter to set the timeout. For instance
