create JUnit 5 test for these code

Question

@Test

public void getEndpoints() {

}

@Test

public void distance() {

}

@Test

public void slope() {

}

@Test

public void midpoint() {

with this code:

public Point2D[] getEndpoints() {

Point2D[] endpoints = new Point2D[2];

endpoints[0] = endPoint1.copyOf();

endpoints[1] = endPoint2.copyOf();

return endpoints;

}

public double distance() {

return endPoint1.distance(endPoint2);

}

public double slope() {

return endPoint1.slope(endPoint2);

}

public Point2D midpoint() {

return endPoint1.midpoint(endPoint2);

}

Answer 1

To create JUnit 5 tests for your code, you need to follow these steps:

Setup: Create a setup method to initialize the objects required for your tests.

Test Cases: Write test cases for each method (getEndpoints, distance, slope, midpoint).

Assertions: Use appropriate assertions to validate the expected results.

Here is a basic structure for your test cases: import static org.junit.jupiter.api.Assertions.*;

import org.junit.jupiter.api.BeforeEach;

import org.junit.jupiter.api.Test;

public class YourClassNameTest {

private YourClassName yourObject; // Replace with your class name

private Point2D endPoint1;

private Point2D endPoint2;

@BeforeEach

public void setup() {

// Initialize your objects here

endPoint1 = new Point2D(/* parameters if needed */);

endPoint2 = new Point2D(/* parameters if needed */);

yourObject = new YourClassName(endPoint1, endPoint2);

}

@Test

public void getEndpointsTest() {

Point2D[] expected = {endPoint1, endPoint2};

Point2D[] actual = yourObject.getEndpoints();

assertArrayEquals(expected, actual, "getEndpoints method should return the correct endpoints.");

}

@Test

public void distanceTest() {

double expected = endPoint1.distance(endPoint2);

double actual = yourObject.distance();

assertEquals(expected, actual, "distance method should calculate the correct distance.");

}

@Test

public void slopeTest() {

double expected = endPoint1.slope(endPoint2);

double actual = yourObject.slope();

assertEquals(expected, actual, "slope method should calculate the correct slope.");

}

@Test

public void midpointTest() {

Point2D expected = endPoint1.midpoint(endPoint2);

Point2D actual = yourObject.midpoint();

assertEquals(expected, actual, "midpoint method should return the correct midpoint.");

}

}
