Question

Please help, write the code for the test cases:

public class JunitTest_RideRequestTest {

public Timeout globalTimeout = Timeout.seconds(1);

@Test

public void test_0_0_StaticFields() {

try {

List<Field> fields = Arrays.asList(RideRequest.class.getDeclaredFields());

int nStatic = 0;

for (Field f : fields) {

int mod = f.getModifiers();

if (Modifier.isStatic(mod)) {

nStatic++;

}

assertTrue("there should be three static field", nStatic == 3);

} catch (Exception x) {

fail("exception occurred trying to get the fields of this class");

}

@Test

public void test_0_1_NumberofFields() {

Field[] allFields = RideRequest.class.getDeclaredFields();

assertEquals("The total number of data field should be 7", 7, allFields.length);

}

// Test default constructor

@Test

public void test_1_0() {

RideRequest rideRequest = new RideRequest();

RideRequest.setTaxrate(0.1); // Assuming 10% tax rate

RideRequest.setDiscount(0.2); // Assuming 20% discount rate

assertNotNull("RideRequest object should not be null", rideRequest);

assertEquals("Default customer name should be empty", "", rideRequest.getCustomerName());

assertEquals("Default ride details should be empty", "", rideRequest.getRideDetails());

assertEquals(0.0, rideRequest.getRidePrice(), 0.0);

assertFalse("Default hasDiscount should be false", rideRequest.isHasDiscount());

}

// Test parameterized constructor with valid input

@Test

public void test_1_1() {

RideRequest request = new RideRequest("John , Downtown , 50.0 , Y ");

String errorMsg = String.format(

"\n Test constructor failed. Returned CustomerName (%s) " + "but correct CustomerName is (%s)",

request.getCustomerName(), "John");

assertEquals(errorMsg,"John", request.getCustomerName());

errorMsg = String.format(

"\n Test constructor failed. Returned RideDetails (%s) " + "but correct RideDetails is (%s)",

request.getRideDetails(), "Downtown");

assertEquals(errorMsg, "Downtown", request.getRideDetails());

assertEquals("Error: The constructor failed to set the ride price.",50.0, request.getRidePrice(), 0.0);

assertTrue("Error: The constructor failed to set the ride discount.",request.isHasDiscount());

}

@Test

public void test_1_2() {

RideRequest request = new RideRequest(" Jack , North York , 9.99 , Y ");

String errorMsg = String.format(

"\n Test constructor failed. Returned CustomerName (%s) " + "but correct CustomerName is (%s)",

assertEquals(errorMsg, "North York", request.getRideDetails());

assertEquals("Error: The constructor failed to set the ride price.",9.99, request.getRidePrice(), 0.0);

assertTrue("Error: The constructor failed to set the ride discount.",request.isHasDiscount());

}
