by Audrey Nanual

layout: center

Testing Framework

  • a collection of reusable code that provides functionality to support unit testing, such as assertion methods, mock objects, or test data generators
  • e.g. JUnit 5, Mockito, SpringFramework Testing, Spring Boot Testing, Selenide

Testing Library

  • a set of conventions and rules that define how tests are written, organized, and executed
  • e.g. AssertJ, Data Faker, Easy Random, Easy Random JUnit Extension, ModelAssert,

Testing Tool

  • a software application that helps developers automate and manage the process of testing software
  • e.g. JUnit Pioneer, Database Rider, TestContainers, Instancio, JetBrains Aqua
