Testing

Testing is a critical aspect of software development as it ensures that your microservices are reliable, secure, and function as expected.

Here are various testing techniques and best practices for Node.js microservices:

• Unit testing:
  • Purpose: Test individual units or components of your microservices in isolation
  • Tools: Use testing frameworks such as Mocha, Jest, or Jasmine, and assertion libraries such as Chai or Jest’s built-in assertions
  • Techniques: Write tests for functions, classes, and modules, mocking dependencies to isolate the unit being tested
• Integration testing:
  • Purpose: Validate interactions between different components or microservices.
  • Tools: Use testing frameworks and libraries similar to unit testing but focus on scenarios where multiple units interact.
  • Techniques: Test API endpoints, data flows, and integrations with databases or external services. Use real or in-memory databases for more realistic testing.
• End-to-end testing:
  • Purpose: Test...
