Lesson Overview

We will be spending the first hour to learn about software testings, and next 2 hours on quick JavaScript lesson and assignment. At the end of the assignment, learners will see a short demo on unit test within the assignment folder.

Command to run test:

npm run test

If you face issue running jest in the devDependency, a quick remedy is to run npm i -g jest first.

Note for Instructors

  • Run all .js files with node in the Terminal.
  • While running JS code, use debugging terminal to visually guide learners how codes are executed.

Part 1 - Software Development Life Cycle

Source: https://www.javatpoint.com/software-engineering-software-development-life-cycle

  1. Requirement Analysis - Gathering the business and technical requirements.
  2. Defining - Defining the functional and non-functional requirements.
  3. Designing - Translating the functional requirements into workable tasks.
  4. Coding - Writing code a.k.a. development phase.
  5. Testing - Ensuring the outcome of development aligns with the defined requirements.
  6. Deployment - Going live into production.
  7. Maintenance - Monitoring systems health and fix errors when arises.

Part 2 - Software Testing Methods

Functional Testings

  1. Unit Test - An isolation testing targeting at the smallest piece of logic in the software.
  2. Integration Test - Testing multiple software modules together as a group.
  3. Acceptance Test - Testing the functionality of the software by end users before launch.

Non-functional Testings

  1. Performance Test - A non functional test to determine the stability, speed, responsiveness and resilience of the system.
    1. Load Test - Simulate an increasing amount of traffics/requests sent to the system.
    2. Stress Test - Determine the peak load and/or how much requests the system can receive.
    3. Endurance Test - Determine the behaviour of the system at the peak load over time.
  2. Security Test -
    1. Dependency Vulnerabilities - Scanning for vulnerabilities introduced by dependencies.
    2. Secrets & Data Storage Strategy - Determine how secure are secrets and sensitive data being stored.

Part 3 - Group Discussion

Understanding Part 1 and Part 2, learners will be grouped in a team of 3 or 4 to research (google), discuss and fulfil the blanks in the following table. Learners may simple use google docs for this.

The Test When? (SDLC) How are they performed?
Unit Test Enter 1 to 7 3 sentences max
Integration Test Enter 1 to 7 3 sentences max
Acceptance Test Enter 1 to 7 3 sentences max
Performance Test Enter 1 to 7 3 sentences max
Security Test Enter 1 to 7 3 sentences max

Bonus Question: Are there any other forms of software/system testings that are not listed in this lesson?

Example

The Test When? (SDLC) How are they performed?
Security Test 5,6,7 and 7 It can be done with automation, engage testing companies, or AI

Part 4 - Data Types in JavaScript

The primitive data types of JavaScript are:

  • number
  • string
  • boolean
  • null
  • undefined
  • symbol (advanced, not covering)

The composite types are:

  • object
  • array

Check out this JS file.

Part 5 - Arrays

Arrays consist of indices and values.

Look at the basic use of array here.

Part 6 - Objects

Objects are made up with key-value pairs that represent properties and values. In some programming languages, the name of the data structure is "Dictionary". In JavaScript, they are called objects.
