Software Testing and Devops

App Description

• Web application in which we can add notes.
• User must be logged in in order to use application.
• Tools : Flask - Sqlite3

Software Testing

1. Unit Testing
2. Integration Testing
3. E2E Testing
4. User Acceptance Testing

Unit Testing

• In unit test I tested 8 functions,6 functions in NotesRepo (testShowAllNotes, testNumberOfNotes, testShowNoteById, TestAddNote, TestUpdateNote, TestDelete) and 2 functions in AuthRepo(testSignIn, testSignUp).

• There are 3 phases to each test:

  • Given
  • When
  • Then

• To run unit tests we can use the command :

coverage run -m unittest Tests/UnitTests/test_units.py

• To see the result of unit tests coverage we can use the commande :

 coverage report

Integration Testing

• In Integration test I tested 8 functions (test_register, test_login_page, test_signin_fail, test_signin_success, test_logout, test_notes, test_create_note_page, test_Note_add)

• There are 3 phases to each test: - Given - When - Then

• Tests are performed by testing the status code of the response as well as checking if the expected result is included in the response page.

• To run integration tests along with unit tests we can use the command :

coverage run -m pytest

• To see the result of integration tests along with unit tests coverage we can use the commande :

 coverage report

E2E testing

• In E2E tests I tested 3 functions (test_01_register, test_02_signin, test_03_add_Note).
• I used Selenium for this test.
• The navigations by the selenium are saved as screenshots. These screen shots are saved in the file Screenshots.
• To run e2e tests we can use the command :

coverage run -m unittest Tests/E2E/test_e2e.py

User Acceptance Testing (UAT)

• It is divided into 8 sections:
  • UAT Scope
  • UAT Assumptions and Constraints
  • UAT Risks
  • UAT Team Roles & Responsibilities
  • UAT Entry Criteria
  • UAT Requirements-Based Test Cases
  • UAT Test Results
  • Document Signatures

Devops CI/CD Pipeline

What is CI CD?

• CI/CD is a method to frequently deliver apps to customers by introducing automation into the stages of app development. The main concepts attributed to CI/CD are continuous integration, continuous delivery, and continuous deployment.

CI

• The workflow had 2 jobs the first one is a Test Job and the second is a Build job.
• In the test job we test the app with integration tests, unit tests and e2e tests.
• In the build job we build a docker image and pushed it to docker hub

CD

• I added to the workflow another job : Deploy job
• For the deployment i used ECS.
• I created a cluster then a task definition then a service.
• The service has 3 tasks.
