Challenges and considerations when testing applications running in containers

Next to all the many advantages that testing applications running in containers brings to the table, we need to also have a brief discussion of the challenges and considerations involved in this type of testing, such as dealing with dependencies and managing test data:

• Isolation: Testing applications in containers can provide a level of isolation between the test environment and the host system, which can be useful for ensuring that the test results are consistent and repeatable. However, this isolation can also make it more difficult to debug issues and identify the root cause of problems, as you may not have access to the host system and its resources.
• Environment consistency: Ensuring that the test environment is consistent across different development environments can be a challenge when using containers. Differences in the host system, container runtime, and network configuration can all...
