Parameterized test

Look at the test class:

@TestInstance(TestInstance.Lifecycle.PER_CLASS)
class CalculatorTest {

    @ParameterizedTest
    @MethodSource("argFactory")
    fun testMinOf(first: Int, second: Int, expected: Int) {
        val result = Calculator().minOf(first, second)
        assertEquals(expected, result)
    }

    fun argFactory(): List<Arguments?>? {
        return listOf(arguments(2, 1, 1), arguments(31, 10, 10), arguments(5, 0, 0))
    }
}

It's written for the class:

class Calculator {

    fun minOf(a: Int, b: Int): Int {
        return if (a <= b) a else b
    }
}

What will be the result of the test class?
