DbMocker 1.3.0

This .NET library simplifies data mocking for UnitTests, to avoid a connection to a relational database. DbMocker use the standard Microsoft .NET DbConnection object. So, you can mock any toolkit, including EntityFramework, Dapper or ADO.NET; And for all database servers (SQL Server, Oracle, SQLite).

First, add the (DbMocker NuGet packages)[https://www.nuget.org/packages/DbMocker]. Next, instanciate a MockDbConnection and mock you SQL requests using a condition and return a DataTable.

Please, contact me if you want other features or to solve bugs.

// Sample method from your DataService
public int GetNumberOfEmployees(DbConnection connection)
{
    using (var cmd = connection.CreateCommand())
    {
        cmd.CommandText = "SELECT COUNT(*) FROM Employees";
        return Convert.ToInt32(cmd.ExecuteScalar());
    }
}

[TestMethod]
public void UnitTest1()
{
    var conn = new MockDbConnection();

    // When a specific SQL command is detected,
    // Don't execute the query to your SQL Server,
    // But returns this MockTable.
    conn.Mocks
        .When(cmd => cmd.CommandText.StartsWith("SELECT") &&
                     cmd.Parameters.Count() == 0)
        .ReturnsTable(MockTable.WithColumns("Count")
                               .AddRow(14));

    // Call your "classic" methods to tests
    int count = GetNumberOfEmployees(conn);

    Assert.AreEqual(14, count);
