Testing

Example test class

import org.junit.jupiter.api.Assertions.*
import org.junit.jupiter.api.Test

class nameOfClassThatsToTestTests{

    @Test
    fun nameOfFunctionThatsToTest_nameOfTestDataSetThatsUsed() {
        // Arrange
        val a = 3
        val b = 5

        // Act
        val result = a + b

        // Assert
        assertEquals(8, result, "Addition failed: $a + $b should be 8")
    }
}

How to acces Test Data

There are several ways to access test data:

• Using Hardcoded Data:

@Test
fun testAddition() {
    val a = 3
    val b = 5
    val result = a + b
    assertEquals(8, result, "Addition failed: $a + $b should be 8")
}

• Using External Configuration Files:

@Test
fun testAddition() {
    val testData = loadTestData("testdata.json")
    val result = testData.a + testData.b
    assertEquals(testData.expectedResult, result, "Addition failed")
}

• Using Test Fixtures and Factories

@Test
fun testAddition() {
    val testData = TestDataFactory.createTestData()
    val result = testData.a + testData.b
    assertEquals(testData.expectedResult, result, "Addition failed")
}
