StrangerData 101.0.1

StrangerData - A .NET database populator for testing purposes

Project Description

StrangerData is a tool designed to automatically fills your database with random data to make your unit/integration tests faster.
The generator will auto maps all foreign keys and generates records to related tables.

Getting Started

1. Install StrangerData with NuGet Package Manager:

Install-Package StrangerData

2. Install your database dialect, example:

Install-Package StrangerData.SqlServer

3. Configure the required connection strings.

To start generating your test data, create a new DataFactory object:

using StrangerData;
using StrangerData.SqlServer;
...
var dataFactory = new DataFactory<SqlServerDialect>("MyConnectionString");

Usage

Consider the example schema:

Person Table

Team Table

1. Creates a single record:

...
IDicionary<string, object> record = dataFactory.CreateOne("dbo.Person");

The method will creates an record in the group table, and associates it to the created user. The dictionary will contains:

{
  "Id": "Generated User's Id",
  "Name": "Random string",
  "Email": "Random string",
  "Age": "Random integer number",
  "TeamId": "Id from generated group record"
}

So you can specify your custom values. Do following:

User user = dataFactory.CreateOne("dbo.Person", t => {
    t.WithValue("Name", "Will Byers");
});

The dictionary will contains:

{
  "Id": "Generated User's Id",
  "Name": "Will Byers",
  "Email": "Random string",
  "Age": "Random integer number",
  "TeamId": "Id from generated group record"
}

2. Delete generated records:

To delete all generated records, just run:

...
dataFactory.TearDown();
...

We suggest to use the TearDown() method inside yor Finally scope. This way it will run even if you code crashes on running, avoiding to have dirty data on your database.
