Creating reliable environments for running automated tests is a perennial problem, particularly as the number of components that modern systems depend on keeps increasing. Testcontainers is a Java library that helps mitigate this challenge by managing dockerized dependencies for your tests. This is particularly useful for spinning up repeatable database instances or similar infrastructure, but it can also be used in web browsers for UI testing. Our teams have found this library to be helpful for making integration tests more reliable with these programmable, lightweight and disposable containers.
