 In addition to the back up, we also have codes related to Unit Testing and Continuous Integration(Python pytest, Jest, PHPUnit, GitHub Actions, Generative AI) for COMP 333: Software Engineering 2023
 Homework 5
 
+## Python test
 
-## Python
-```pip install pytest```
+### Problem 1 (unit test without pytest)
 
+Please run the code at PythonCode/problem1.py (Through terminal)
+
+```
+python -u "PythonCode/problem1.py"
+```
+
+### Problem 2 (unit test with pytest)
+
+How to set up the environment: (Through terminal)
+
+```
+pip install pytest
+```
+
+Run the test: (Through terminal)
+
+```
+pytest
+```
+
+## Backend Test
 
-## Backend
 ### Environment Config
-### Hard code id; username; password
+
+Please setup the phpunit following testing-tutorial on class website.
+
+### How to run
+
+Navigate to the backend folder of backend
+
+```
+cd backend
+./vendor/bin/phpunit tests/StackTest.php
+```
+
+### Hard coded id (song_id), username, password
+
+For testRegister, testLogin, testFailLogin:
+the unsername and password are hard coded, make sure such user doesn't exist in the database before the test.
+
+```
+'username' => 'test_admin',
+'password' => '1234567890aaa',
+```
+
+In the testUpdateSong and testDeleteSong tests, we use the song_id as a parameter to identify the specific song we want to update or delete. This song_id is automatically generated and incremented in our SQL database whenever a new song is added.
+
+Therefore, when writing or updating these tests, it's crucial to ensure that the song_id used in the test matches the song_id of the song you expect to be present in the database. This is because the song_id in the database will automatically increment each time a new song is added.
+
+In other words, if you're writing a test to update or delete a song that you've just inserted into the database for testing purposes, you need to know the song_id that was assigned to that song and use it in your test. If the song_id in the test doesn't match any song_id in the database, the test will fail because it can't find the song it's supposed to update or delete.
+
+```
+'id' => '53',
+'username' => 'test_admin',
+'song_artist' => 'test_admin',
+'song_name' => 'admin_song',
+'song_rating' => '4',
+```
+
+```
+'id' => '53',
+'username' => 'test_admin',
+```
