CSE 270: Software Testing

W05 Activity: Fault Injection Test

Overview

To test the resiliency of a system, a software tester will often use chaos engineering.

Chaos engineering is used to test and improve the resilience and reliability of software systems. It involves intentionally introducing controlled and measured forms of failure into a system to observe how it responds and to identify potential weaknesses or vulnerabilities.

The primary goal of chaos engineering is to proactively identify and address issues that can lead to system failures, downtime, or degraded performance before they occur in production. By subjecting a system to controlled chaos, engineers can gain insights into how it behaves under unexpected conditions and use that knowledge to make the system more robust and resilient.

Instructions

Configure your test environment as follows (If you need a refresher view W04 Activity: Setup a Local Test Environment):

• Use the Chamber of Commerce v1.4 file found here cse270-v14.zip↓ to conduct your test.
• Notice that the following changes are in place:

  Line 3: Set the APIKEY to "INVALID_KEY"
  Line 8: Set the apiURL to WEATHER_URL_PROD
  Line 14: Set the businessDataUrl to DIRECTORY_DATA_URL_TEST
              

  Your config.js file should match the image below.

  

• Start the web server by selecting the index.html file then clicking the "Go Live" button in VS Code.
• Do not start the directory data server.
• Your environment is now set up to fail both the weather and the directory data server API calls.
