As companies are developing more container-based apps, the concept of testing them is also evolving.
As you are aware, testing has various facets, involving stability, usability, as well as security.
Given how many businesses are adapting container testing, it has become the talk of the town.
The advantage of containers is their portability and scalability. However, it is being discovered that, like with many previous development methodologies and supporting technologies, there are numerous variables to consider.
Container Testing Best Practices
Containers are increasingly being used by developers to build and deploy applications, but how can you ensure they are safe and thoroughly tested for performance? Here are some of the best practices that you must consider while conducting container testing:-
1. Choose a Location for Testing
Choose a location for the application container testing. It’s not always clear where to run the containers during development testing so that the containers may be tested. Nesting, or executing one container runtime within another, is a significant issue. Today, a whole class of tools and services exist that address the nesting problem, such as Google Cloud Build for creating Docker images and Test containers Cloud, operated by Atomic Jar, for evaluating containers but lacking a locally accessible container runtime.
Testing for aggregation is necessary while developing or designing services. When designing services, keep in mind that several of them will combine to form composite services that applications can use.
2. Independently Evaluate Services
They are a minor component of a larger program or containerized application. They are not, however, subsystems; rather, they are minor components of subsystems. Therefore, you must test them with a great degree of autonomy, which means that the services must be able to both properly work on their own and as a component of a coherent unit. A service that performs poorly in performance testing is likely to cause the systems to which it is tied to lag. Numerous other containers, as well as applications, may use a single service that exists within a container, thus a service that isn’t operating well can slow down everything which uses it.
3. Correctly Sizing Your Container Performance Tests
Don’t get too caught up in fine-grained or coarse-grained details. Because the problems with testing are more performance-related than anything else. Concentrate on choosing the appropriate granularity for the objective and use it within the container. Because of the communications overhead involved when working with so many services, too fine-grained services tend to slow down the process. . They are too coarse-grained and do not offer the necessary autonomic values to facilitate reuse. For this, you will need to collaborate with the service designer.
Container testing is gaining popularity due to its portability and scalability. However, you must follow the best practices mentioned in this blog in order to get the correct results.
