SqlServer Schema

This test:

await Verify(connection);

^{snippet source | anchor}

Will result in the following verified file:

Object types to include

await Verify(connection)
    // include only tables and views
    .SchemaIncludes(DbObjects.Tables | DbObjects.Views);

^{snippet source | anchor}

Available values:

namespace VerifyTests.SqlServer;

[Flags]
public enum DbObjects
{
    StoredProcedures = 1,
    Synonyms = 2,
    Tables = 4,
    UserDefinedFunctions = 8,
    Views = 16,
    All = StoredProcedures | Synonyms | Tables | UserDefinedFunctions | Views
}

Filtering

Objects can be dynamically filtered:

await Verify(connection)
    // include tables & views, or named MyTrigger
    .SchemaFilter(
        _ => _ is TableViewBase ||
             _.Name == "MyTrigger");

Recording

Recording allows all commands executed to be captured and then (optionally) verified.

Call SqlRecording.StartRecording():

await using var connection = new SqlConnection(connectionString);
await connection.OpenAsync();
Recording.Start();
await using var command = connection.CreateCommand();
command.CommandText = "select Value from MyTable";
var value = await command.ExecuteScalarAsync();
await Verify(value!);

^{snippet source | anchor}

Will result in the following verified file:

{
  target: 42,
  sql: {
    Text:
select Value
from   MyTable,
    HasTransaction: false
  }
}

^{snippet source | anchor}

Sql entries can be explicitly read using SqlRecording.FinishRecording, optionally filtered, and passed to Verify:

await using var connection = new SqlConnection(connectionString);
await connection.OpenAsync();
Recording.Start();
await using var command = connection.CreateCommand();
command.CommandText = "select Value from MyTable";
var value = await command.ExecuteScalarAsync();

await using var errorCommand = connection.CreateCommand();
errorCommand.CommandText = "select Value from BadTable";
try
{
    await errorCommand.ExecuteScalarAsync();
}
catch
{
}

var entries = Recording
    .Stop()
    .Select(_ => _.Data);
//Optionally filter results
await Verify(
    new
    {
        value,
        sqlEntries = entries
    });

^{snippet source | anchor}

Interpreting recording results

Recording results can be interpreted in a a variety of ways:

var entries = Recording.Stop();

// all sql entries via key
var sqlEntries = entries
    .Where(_ => _.Name == "sql")
    .Select(_ => _.Data);

// successful Commands via Type
var sqlCommandsViaType = entries
    .Select(_ => _.Data)
    .OfType<SqlCommand>();

// failed Commands via Type
var sqlErrorsViaType = entries
    .Select(_ => _.Data)
    .OfType<ErrorEntry>();
