Integration testing of SpringBoot with MS SQL Server using TestContainers

What is integration testing?

Integration testing is a type of software testing in which individual software modules are combined and tested as a group. The goal of integration testing is to verify that the different modules of a software application can interact with each other correctly. Integration testing typically occurs after unit testing, which is the process of testing individual software modules in isolation.

Why is integration testing important?

Integration testing is important because it helps to ensure that the different components of a software application work together as expected. By testing the interactions between modules, integration testing can help to identify and fix potential problems early in the development process, before they cause major issues. Integration testing can also help to improve the quality of the software application by ensuring that it is more reliable and robust.

How can TestContainers be used for integration testing?

To use TestContainers for integration testing, developers simply need to add the library to their project and then use the provided APIs to create and manage instances of the dependencies they need to test against.
