Hey Imani,
Creating JUnit 5 tests involves writing methods annotated with @Test that will test the functionality of methods in your class. Assuming you have a class that calculates geometric properties such as endpoints, distance, slope, and midpoint, your test methods should create instances of this class and use assertions to check if the methods work as expected.
Here's a template for how you might structure these tests:
getEndpoints Test
This test should create an instance of your class, possibly passing parameters if your class constructor requires them.
Call the getEndpoints method and assert the expected result.
distance Test
Similar to the getEndpoints test, create an instance and call the distance method.
Use assertEquals to compare the expected distance with the actual result.
slope Test
Again, instantiate the class, call the slope method, and assert the expected slope against the actual slope.
midpoint Test
Instantiate, call midpoint, and use assertions to verify that the calculated midpoint is as expected.
Here's a basic example of how these tests might look:
This would be implemented with Java with whatever IDE you're using.
import static org.junit.jupiter.api.Assertions.*;
import org.junit.jupiter.api.Test;
public class GeometryTest {
@Test
public void getEndpoints() {
Geometry geometry = new Geometry(); // replace with actual constructor
// Assume getEndpoints returns an array or a list of endpoint objects
Endpoints expected = new Endpoints(/* expected values */);
Endpoints actual = geometry.getEndpoints();
assertEquals(expected, actual);
}
@Test
public void distance() {
Geometry geometry = new Geometry();
double expected = /* expected distance */;
double actual = geometry.distance();
assertEquals(expected, actual, 0.001); // third parameter is delta for floating point comparisons
}
@Test
public void slope() {
Geometry geometry = new Geometry();
double expected = /* expected slope */;
double actual = geometry.slope();
assertEquals(expected, actual, 0.001);
}
@Test
public void midpoint() {
Geometry geometry = new Geometry();
Point expected = new Point(/* expected midpoint x and y */);
Point actual = geometry.midpoint();
assertEquals(expected, actual);
}
}
Note:
Replace Geometry with the actual name of your class.
Replace the /* expected values */ with the specific values you expect from each test.
The assertEquals method is used for comparison. For floating-point numbers, a delta value is provided to allow for slight differences due to floating-point arithmetic.
This is a basic structure. Depending on your class design and requirements, you might need to adjust the code accordingly.

John
