* Word file clearly describe the test suite (series of test cases) you design for each of the methods in TestWithJUnit.java (one test suite per method). Each test suite should contain at least 5 test cases. Each test case has to be justified: Why did you pick this test case and not another one? Imagine you are limited by time and money about the number of test cases you can pick and run. Why would you make run the test cases you propose? You have to be convincing. In particular, you have to address: WHAT each test case aims to test, and HOW you expect the method to run on this test case (what output do you expect?).

*In a new java file, that you will call TestWithJUnitTester.java, write a JUnit test for each of the test cases you have described in your word file.

* Run your test cases and report the results in your word document. In particular, you have to report whether the method behaves as expected or not on each test case, and propose an explanation in case the method does not behave as expected.

Note: your test cases cannot include the examples given within the code.

Advice: when designing test cases, think:

1/ regular functionality test: does the code perform as expected under normal/expected circumstances?

2/ edge case: does the code still perform when under stress of its expected conditions?

You need to have at least one of the first type (maybe two depending on how complex the code is), and 3 or 4 of the second type.

You are asked to develop a cash register for a fruit shop that sells oranges and apples. The program will first ask the number of customers. Subsequently, for each customer, it will ask the name of the customer and the number of oranges and apples they would like to buy. And then print a summary of what they bought along with the bill as illustrated in the session below:

How many customers?  2    
Name of Customer 1  Harry  
Oranges are $1.40 each. 
How many Oranges?  1  
Apples are $.75 each. 
How many Apples?  2  
Harry, you bought 1 Orange(s) and 2 Apple(s).  
Your bill is $2.9    
Name of Customer 2  
Sandy  
Oranges are $1.40 each. 
How many Oranges?  10  
Apples are $.75 each. 
How many Apples?  4  
Sandy, you bought 10 Orange(s) and 4 Apple(s).  
Your bill is $17.0

Exercise 1:

Write an XML document describing the exercises in this document: the root element is <exercises>. The root has an attribute number that has value 1. The root element has three child elements; <date> that contains as text the date of the exercise, and two <item> elements for the first two exercises (1--2). Write some text in the <item> elements.

Exercise 2:

Write an XML document describing a person: name, occupation, address and hobbies. Please do not use your own information, you can use fake data. Decide on suitable element names and nesting. Check your document for well-formedness.

Exercise 3:

Draw a tree that represents the XML document you created in task 2.

Python 3 Program

Program 4 should first tell users that this is a word analysis software. For any user-given text file, the program will read, analyze, and write each word with the line numbers where the word is found in an output file. A word may appear in multiple lines. A word shows more than once at a line, the line number will be only recorded one time.

Ask a user to enter the name of a text file. Using try/except for invalid user input. Then the program reads the contents of the text file and create a dictionary in which the key-value pairs are described as follows:

Key. The key are the individual words found in the file.

Value. Each value is a list that contains the line numbers in the file where the word (the key) is found. Be aware that a list may have only one element.

Once the dictionary has been built, the program should create another text file for otuput, named “words_index.txt”. Next, write the contents of the dictionary to the file as an alphabetical listing of the words that are stored as keys in the dictionary (sorting the keys), along with the line numbers where the words appear in the original file. Please see the sample file for your reference.

Looking to seeing everyone to submit a well-done program! Here are some tips:

Documents/Comments of your program (Never more)

Testing your program by the given two files, Kennedy.txt . The output file of the Kennedy_index.txt, Kennedy_index_B.txt, Kennedy_index_C.txt, for input file “kennedy.txt”

Remember the output file name of your program is words_index.txt.

For this program, not running one (syntax error) will receive NO point.

Draw an ER diagram containing the ConferenceSeries, 
the ConferenceEvent, and the ConferenceTrack
entitysets where each ConferenceSeries can be linked 
to zero or many ConferenceEvent entities, and each 
Conference Event may be linked to one or many 
ConferenceTracks. ConferenceTrack should not exists 
without a ConferenceEvent. Choose an appropriate 
relationship name. Then augment the model with an 
entityset Venue and a relationship named OrganizedAt
associating each ConferenceEvent with exactly one Venue. 
Assume that a Venue must have run at least one 
ConferenceEvent.  Your ER diagram should show all details.

I need to make changes to code following the steps below. The code that needs to be modified is below the steps. Thank you.

1. Refactor Base Weapon class:

a.            Remove the Weapon abstract class and create a new Interface class named WeaponInterface.

b.            Add a public method fireWeapon() that returns void and takes no arguments.

c.             Add a public method fireWeapon() that returns void and takes a power argument as an integer type.

d.            Add a public method activate() that returns void and takes an argument as an boolean type.

2. Refactor the specialization Weapon Classes:

a.            Refactor the Bomb class so that it implements the WeaponInterface class.

b.            Refactor the Gun class so that that it implements the WeaponInterface class.

3. Refactor the Game Class:

a.            Remove all existing game logic in main().

b.            Create a private helper method fireWeapon() that takes a WeaponInterface as an argument as a weapon. For the passed in weapon activate the weapon then fire the weapon.

c.             Create an array of type WeaponInterface that can hold 2 weapons.

d.            Initialize the first array element with a Bomb.

e.            Initialize the second array element with a Gun.

f.             Loop over the weapons array and call displayArea() for each weapon.
