Chapter 1 : Backend API Development

Backend API Development

Build a Backend for your App.

Using development automation, build secure & scalable backend server with EasyManage API builder, use suitable database choice.

Data Modeling

Please refer to tutorial:

• Data Modeling

Testing - tests

• tests UT Unit Tests, IT Integration Tests

Unit Tests

• Testing Frameworks and Tools Used

  • JUnit
  • Mockito

• Unit Tests generated

  • emapi project generates unit tests for -
    • Service Unit Test
      • e.g. emapi\lib\base-app\test\Product\ProductServiceUTest.java
    • Controller Unit Test
      • e.g. at emapi\app\dbrest\test\Product\ProductDataRestControllerUTest.java

Integration Tests

• Testing Frameworks and Tools Used
  • JUnit
  • Mockito
    • Using @MockBean

info

Generated tests are based on this approach:

• Integration testing with @MockBean in Spring Boot involves replacing a real bean in the application context with a mock object. This allows for isolating and testing specific components of an application in integration tests.
• For integration tests focussing on integrating different layers of the application, with no mocking involved, below are provided:
  • tests API Tests - TestNG, WebClient

• Integration Tests generated

  • emapi project generates integration tests for -
    • Controller
      • e.g. emapi\app\dbrest\test\Product\ProductRestApiITest.java

Run Tests

Make sure properties are set,

• <skipUTs>false</skipUTs>

• <skipITs>false</skipITs>

• To Run tests : Build project - verify

  • mvn clean verify
