Testing on containers helps streamline testing infrastructure, the sanity of the test environment, and scaling of the test environment. Similar to the development, testing on containers has also been gaining a lot of traction due to the multitude of problems it solves. This is how containers changed the way applications were deployed with more efficient use of resources. Containers when clubbed with autoscaling made better use of the underlying hardware. Testing Strategies in Monolithic vs Microservices Architecture vary and need to be worked out accordingly.

These microservices were deployed onto ephemeral containers that temporarily run in the existing pod, thus reducing inconsistent hardware usage. The way applications were designed has changed with time as Microservices are gaining prominence over Monoliths. The advent of Continuous Integration and Continuous Delivery (CI/CD) has created a conducive environment for implementing container technologies.
