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.

// shortened code for readability [GeneratedCode("Sungaila.InlineTest", "1.0.0+17ac90a4b0b471c88edc5fcedee4124a7cbbac28")] [TestClass] public partial class ReadmeExampleTests { [TestMethod] [DataRow(6, 3, 2)] [DataRow(1, 1, 1)] public void DivideAreEqual(int dividend, int divisor, int expected) { var result = ReadmeExample.Divide(dividend, divisor); Assert.AreEqual(expected, result); } [TestMethod] [DataRow(10, 1, 42)] public void DivideAreNotEqual(int dividend, int divisor, int notExpected) { var result = ReadmeExample.Divide(dividend, divisor); Assert.AreNotEqual(notExpected, result); } [TestMethod] [DataRow(1, 0)] public void DivideThrowsException_ArgumentOutOfRangeException(int dividend, int divisor) { Assert.ThrowsException<ArgumentOutOfRangeException>( () => ReadmeExample.Divide(dividend, divisor)); } }

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.
