Sungaila.InlineTest 1.0.1

Sungaila.InlineTest

A C# source generator for quick creation of simple unit tests. Just add these attributes to your method:

• [AreEqual]
• [AreNotEqual]
• [IsTrue]
• [IsFalse]
• [IsNull]
• [IsNotNull]
• [IsInstanceOfType<T>]
• [IsNotInstanceOfType<T>]
• [ThrowsException<T>]

Example

[AreEqual(6, 3, Expected = 2)]
[AreEqual(1, 1, Expected = 1)]
[AreNotEqual(10, 1, NotExpected = 42)]
[ThrowsException<ArgumentOutOfRangeException>(1, 0)]
public static int Divide(int dividend, int divisor)
{
	if (divisor == 0)
		throw new ArgumentOutOfRangeException(nameof(divisor));

	return dividend / divisor;
}

The source generator will produce classes containing the matching unit tests.

Restrictions

1. The same Attribute rules apply here. Your parameters have to be either
   • a constant value
   • a System.Type (defined at compile-time)
   • a single-dimensional array of the above
2. The method must not have more than 15 parameters.
3. The method must be defined inside a class or struct.
4. For classes without a parameterless constructor the method must be static.
