Subsonic 3 Active Record TestRepository identity column not incremented

I am Unit Testing with Subsonic 3.0.0.3. Unit tests ran as expected with record count assertions passing. However the testing framework does not auto increment identity columns.

For example

var p1 = new Person() { Name = "Jack" };
p1.Add();
var p2 = new Person() { Name = "Jill" };
p2..Add();
var t1 = Person.SingleOrDefault(p => p.Name == "Jack");
var t2 = Person.SingleOrDefault(p => p.Name == "Jill");

Table structure read by the T4 template

CREATE TABLE Person
(
    Id int IDENTITY(1,1) PRIMARY KEY
    ,Name NVARCHAR(255) NOT NULL 
)

Connection string

<add name="SomeDb" connectionString="Test"/>

t1 and t2 have the name property set as expected, but the Id property is 0 for both.

Is this by design? If so how to deal with tests that require selecting records by ID?

(I don't have enough points to comment yet, but this is in response to cantabilesoftware's answer.)

I have a subtype relationship in my database where two tables are 1->1. I had to modify your template slightly to skip the logic if the key field already has a value assigned:

<#if(tbl.PK.SysType=="long" || tbl.PK.SysType=="int") {#>
            if (TestMode && <#=tbl.PK.CleanName#> == 0)
            {
                this.<#=tbl.PK.CleanName#>=++next_test_autoid;
            }
<#}#>

Here's a change to the ActiveRecord template that I find useful. Basically it handles an int or long primary key column and in test mode auto allocates a new id. Requires two changes to the ActiveRecord.tt template:

1: In the top of the function public void Add(IDataProvider provider){

        public void Add(IDataProvider provider){

<#if(tbl.PK.SysType=="long" || tbl.PK.SysType=="int") {#>
            if (TestMode)
            {
                this.<#=tbl.PK.CleanName#>=++next_test_autoid;
            }

<#}#>

2: Under the line public bool TestMode = false, add:

        public bool TestMode = false;
<#if(tbl.PK.SysType=="long" || tbl.PK.SysType=="int") {#>
        private static <#=tbl.PK.SysType#> next_test_autoid = 0;
<#}#>

The TestRepository has no idea how your DB bits are set (how could it?) so if you want it to auto-increment you'll need to set it yourself.
