A Brief Introduction of Testing Kafka

Nowadays, Kafka is implemented in a lot of companies which are working for Banks, trade markets, financial policies and so on. A huge number of users uses Kafka in a day even trillion of messages get transferred over Kafka.

Most popular example for Kafka is LinkedIn. As we know that, LinkedIn is a professional Application which is useful for all the type of users. Because from there, a user can start his/her own business and can grow up to a very high scale performance and turn over in Billions of dollars.

In this era, a problem for all the owners of these type of functionalities are facing a problem that how they can prevent their information from the outer sources or hackers who can use those info for their benefits? In brief, the most important thing to concern is: how to increase the correctness of the data and performance after build up in the development stage.

It is such a very hard thing to prevent all these things from the outer sources, but we can consider a few guidelines to make them safe.

DESIGN: Improvement in Kafka -

In Kafka, there is a need to use more agile approach, because in Agile, all the things happen in a prefixed sequence. Before developing the inside strategies, a design is the main thing to inspect very well. Like what are core contracts, guarantees, and APIs etc. Because if we don’t know the flow of data then how will be able to explain either we’ve been implemented on a very huge scale.

Code Review -

Before implementing the Kafka on the projects we need to have very technical, extraordinary and experienced hands for that to test that with a lot of efforts before going to the production server. Kafka has the different strategy to test all the written codes by developers and spends time on high-quality performance and lot of privacy of the data and perfection into maintaining the level of correctness.

Unit Testing -

As we know that unit testing is more important than integration testing. Because there is a hierarchy to test anything using different approaches. We can implement unit tests very easily and fastly in a little period of time because it is very easy to debug. But if we discuss for the fully realistic environment then, integrated tests are also very important to execute.

There are more testing techniques and without using them it is impossible to provide a high-quality product with required functionalities -

Stress Testing – Testing the application with a huge number of users and correctness of data too.

Performance Testing – One-time testing is not enough to serve this much important project, we need to test everything on the daily basis.

Compatibility Testing – Once a new version is under development then we need to compare all the old functionalities with new ones, to verify the better quality of newer versions.
