Testing (XUNIT)

[Fact]

[Fact] is used for a single test. The function can not contain data parameters

example

[Fact]
public void ReturnInitialisedCoordinates()
{
    var move = new Move(2, 2);
    Assert.Equal(2, move.X);
    Assert.Equal(2, move.Y);
} 

[Theory]

[Theory] is used to pass through multiple data tests into a single test function

[InLineData(parameters)] is used to pass the data into the test function

example

[Theory]
[InlineData("1,1")]
[InlineData("3,2")]
[InlineData("q")]
[InlineData("2,2")]
public void ValidateCorrectInput(string input)
{
    var inputHandler = new UserInputHandler();
    bool valid = inputHandler.IsValid(input);
    Assert.True(valid);
}

Another example which includes passing through a list

[Theory]
[InlineData(new object[] {new string[] {"1", "11"}})]
[InlineData(new object[] {new string[] {"11", "1"}})]
[InlineData(new object[] {new string[] {"12345", "09766", "12"}})]
public void DetrermineFalseConsistency3(string[] numbers)
{
    var checker = new Checker();
    var result = checker.CheckConsistency(numbers.ToList());

    Assert.False(result);
}

Asserts

The asserts which I use regularly are:

• Assert.Equal (expected, result)
• Assert.True (boolean data)
• Assert.False (boolean data)

Class Structure

At myob we create a new test class for each test we use in the actual code.

for example, if I was going to make a Player class, I would first make a test class called PlayerShould and write all the unit tests for the Player class. Each test in the test class would be named a feature that the player class should have.
