[DataFixture]
[XmlDataProvider("../../sample.xml",")]
[XmlDataProvider("../../sample.xml","DataFixture/Customers")]
public class DataDrivenTests
{
[ForEachTest("User")]
public void ForEachTest(XmlNode node)
{
Assert.IsNotNull(node);
Assert.AreEqual("User",node.Name);
Console.WriteLine(node.OuterXml);
}
[ForEachTest("User", DataType = typeof(User))]
public void ForEachTestWithSerialization(User user)
{
Assert.IsNotNull(user);
Console.WriteLine(user.ToString());
}
}
The file sample.xml looks like this:
<DataFixture>
<Employees>
<User Name="Mickey" LastName="Mouse" />
</Employees>
<Customers>
<User Name="Jonathan" LastName="de Halleux" />
<User Name="Voldo" LastName="Unkown" />
</Customers>
</DataFixture>
and the User class like this:
[XmlRoot("User")]
public class User
{
private string name;
private string lastName;
public User()
{}
[XmlAttribute("Name")]
public String Name
{
get{ return this.name;}
set{ this.name = value;}
}
[XmlAttribute("LastName")]
public String LastName
{
get{ return this.lastName;}
set{ this.lastName = value;}
}
}
How does it work ?
The XmlDataProvider attributes are used to specify an XML filename that contains the data (of course, you can put several of those).
Then a first XPath expression is applied to the data.
Each selected node is then feeded to the ForEachTest which applies a second XPath expression on the node. This allows a fine grained selection of the data.
You can also specify the desired output data type. XmlSerializer is then used to convert XmlNode into the desired object.
