Part 1 - Unit Test

Q1

(60%)

Here is a class of course scheduling system called CSS in course_scheduling_system.py. To be simple, there are five school days and there are class 1 to 8 in each school day, and we assume a course is arranged in continuous classes. A course should be represented as a tuple that contains course name, day, starting class, and ending class, e.g., ('Algorithms', 'Monday', 3, 4).

There are 5 methods of CSS.

  1. __str__: Return the schedule in a formatted way and in the type of str. (str(object) returns type(object).__str__(object), which is the “informal” or nicely printable string representation of object)
  2. check_course_exist: Check whether a course exists
  3. add_course: Add a course into the schedule if the course exists and doesn’t overlap with the other courses in the schedule.
  4. remove_course: Remove a course if it is in the schedule
  5. get_course_list: Return a copyed list of courses in the schedule. The order will be the same as the order they are added.

However, check_course_exist hasn’t been implemented yet, but you want to test the rest of the class CSS. Please write a python unit test named course_scheduling_system_test.py to fulfill the the following requirements and it should run with python -m unittest and python course_scheduling_system_test.py. Here are some fundamental requirements first.

  • Please write a test method for each requirement below and name it in the form of test_q1_x, e.g., test_q1_1.
  • Don’t access any attribute whose name is starting with double underscore directly, e.g., __str__.
  • Don’t modify course_scheduling_system.py unless it says so.

If you don’t know mock, you can change ``check_course_exist`` to return ``True`` in ``course_scheduling_system.py`` directly and answer the questions except q1_3 and you will get only 70% points of them.

q1_1 (5%)

Let check_course_exist return True by mocking (Stub). Try to add one course by add_course, check its return value, and verify the result by get_course_list.

q1_2 (5%)

Let check_course_exist return True by mocking. Try to add two courses overlapping with each other, check its return value, and verify the result.

q1_3 (5%)

Let check_course_exist return False by mocking. Try to add one course, and check its return value.

q1_4 (10%)

Let check_course_exist return True by mocking. Try to add a invalid course input, and check the Exception raised.

q1_5 (20%)

Let check_course_exist return True by mocking. Try to add three courses that don’t overlapp with each other and then remove the second one by remove_course, verify the result, and then check the call count of check_course_exist. Also, try to print out the schedule in a formatted way.

q1_6 (15%)

Add some more (possibly 0) tests to achieve 100% coverage of course_scheduling_system.py. You can mock check_course_exist and use pragma to excluding check_course_exist from coverage analysis.


Part 2 - Selenium

Please write a Python program named app.py that use Selenium with below options, and fulfill the following requirements.

options = Options()
options.add_argument('--headless')
options.add_argument('--window-size=1920,1080')
options.add_argument('--disable-gpu')

Q2-1

(15%)

  1. Go to https://docs.python.org/3/tutorial/index.html. (2%)
  2. Select the language options on the navigation bar (Fig. 1), and choose the Traditional Chinese option. Note that any selenium operation is legal except for changing the URL directly. (10%)
  3. Wait for lanugage translation, then use find_element to get the title and the first paragraph (Fig. 2). Print the title and the first paragraph. (3%)

Q2-2

(15%)

  1. Find the search box on the navigation bar (Fig. 3), and send keys to search for class. Note that any selenium operation is legal except for changing the URL directly. (10%)
  2. Please use implicit or explicit wait in Selenium to wait for the searching result (Fig. 4), and print the top five listed titles. Note that you will get no point if you use sleep(). (5%)

Part 3 - Continuous Integration

(10%)

To verify Q1 and Q2, please write a GitHub Action configuration file named Midterm-CI.yml that includes the following commands.

# Q1
$ python3 course_scheduling_system_test.py  -v 1>log.txt
$ cat log.txt

# Q2
$ python3 app.py
