- Assume the base package for an Eclipse project is edu.westga.cs1301.drinks and that you are writing tests for the dispense method of a DrinkMachine class. Use this information to answer the following questionWhat should you name your test class?a) write the definition of the 4 methods as described in the definition of the clas TestClass. b) write a complete demo test program with the main() to test All of the operations of the TestDemoClass class.This question involves the design of a class that will be used to produce practice problems. The following StudyPracticeinterface represents practice problems that can be used to study some subject. public interface StudyPractice. { /**Returns the current practive problem */ String getProblem(); /** Changes to the next practice problem */ void nextProblem(); } The MultPractice class is a StudyPracticethat produces multiplication practice problems. A MultPractice object is constructed with two integer values: first integer and initial second integer. The first integer is a value that remains constant and is used as the first integer in every practice problem. The initial second integer is used as the starting value for the second integer in the practice problems. This second value is incremented for each additional practice problem that is produced by the class. For example, a MultPractice object created with the call new MultPractice (7, 3)would be used to create the practice…
- The purpose of this exercise is to allow the student to demonstrate their understanding of application development, the creation and use of classes and objects in Python, and using the other tools (selection, iterations, functions, etc.) we have learned this term. We will make a simple game called 'Stray Cat Strut' - Using the grid class discussed in Chapter 9, create a 20 x 20 cell game board- This game board represents a backyard- Create a class called animal with two attributes:-- an attribute called 'location' which is a grid coordinate (e.g., B3)-- an attribute called 'lives' which is an integer.- The animal class has the standard methods (init, str, etc.) plus one additional method:-- a method called 'move' that changes the animal's location one cell up (N), one cell right (E), one cell down (S), or one cell left (W). - Extend the animal class to a subclass called cat, and another subclass called dog- cat inherits the animal attributes and methods, but also has the following…Select all the statements that are true about Python's unittest module and Django's test framework: a. Django's test framework builds on Python's unittest module b. Django's TestCase class is a sub-class of unittest.TestCase c. A collection of unit tests is called a "test suite" d. Unit tests are run using the same database that the programmer uses for the development server e. HTML assert methods (such as assertHTMLEqual) are already part of Python's unittest.TestCaseHelp, I am making a elevator simulation using polymorphism. I am not sure to do now. Can you help me improve this code. Please if possible don't change what I have too much. Any help would be appreciated. My code is at the bottom, that's all I could think off. There are 4 types of passengers in the system:Standard: This is the most common type of passenger and has a request percentage of 70%. Standard passengers have no special requirements.VIP: This type of passenger has a request percentage of 10%. VIP passengers are given priority and are more likely to be picked up by express elevators.Freight: This type of passenger has a request percentage of 15%. Freight passengers have large items that need to be transported and are more likely to be picked up by freight elevators.Glass: This type of passenger has a request percentage of 5%. Glass passengers have fragile items that need to be transported and are more likely to be picked up by glass elevators. public abstract class Passenger {…

The problem I have uses a main.cpp file alongside a dateTypelmp.cpp file. This solution does not solve the task as I understand it to be. The class dateType was designed to implement the date in a program, but the member function setDate and the constructor do not check whether the date is valid before storing the date in the member variables. Function setDate and the constructor need to be rewrit so that the values for the month, day, and year are checked before storing the date into the member variables. A member function should be included, isLeapYear, to check whether a year is a leap year. Input should be format month day year with each separated by a space. Output should resemble the following: Date #: month-day-year If the year is a leap year, print the date and a message indicating it is a leap year, otherwise print a message indicating that it is not a leap year. The header file for the class dateType has…
