DbMocker - Simple Database Mocker for UnitTests

Introduction

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. 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());
    }
}

/* Create a text file "123-EMPLOYEES.txt" with this content
   And set the build property to "Embedded resource".
        Id        Name          Age
        (int)     (string)      (int?)

        10        Scott         21
        20        Bill          NULL
*/

[TestMethod]
public void UnitTest0()
{
    var conn = new MockDbConnection();

    // The text file "123-EMPLOYEES.txt" is embedded in this project.
    // See the Samples folder.
    //  - 123       is an identifier (as you want)
    //  - EMPLOYEES is the CommandText Tag 
    //    See https://docs.microsoft.com/en-us/ef/core/querying/tags
    conn.Mocks.LoadTagsFromResources("123-EMPLOYEES");

    // Call your "classic" methods to tests
    var data = GetEmployees(conn);

    // DbMocker read the embedded file 
    // and associated the content to the tag
    Assert.AreEqual("Scott", data[0][1]);
    Assert.AreEqual("Bill", data[1][1]);
}

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

    // When a specific SQL command is detected,
    // Don't execute the query to your database engine (SQL Server, Oracle, SQLite, ...),
    // But returns this _Table_.
    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);
}
