Gyansetu Team Software Testing

The twenty-first century is known as the era of technology, and the rapidly advancing domain of software development plays a huge part in it. Presently, there is a growing trend of adopting microservice architectures.

This transition is primarily due to its substantial benefits, such as elevated efficiency, scalability, and modularity, making them an impressive alternative for companies or groups of various scales or sizes. This communication occurs with the help of a Representational State Transferor REST, Application Program Interface, or API.

Microservices architecture involves breaking big software projects into small conveyable modules, which can be independently tested. Although microservices are required to communicate about their updates regularly, it still makes the execution quite easy.

However, microservices testing becomes more complicated due to an increased number of independent parts. Therefore, various tests are conducted to guarantee the smooth running of the service. 

Importance of Microservices testing 

Microservices are expensive and consist of several server spaces and a communication mechanism. Testing these services before release leads to quality delivery and faster production. It also decreases the chance of any kind of complications.

By wielding testing tools for microservices, software developers can ensure the proper functioning and save a lot of effort and time.

What are various types of Microservices testing methods?

Here are some of the testing methods –

  • End-to-End Testing – This testing method helps confirm that all components are working together to meet the surface requirements. It is one of the best testing tools for critical paths and assesses the entire transaction, verifying all microservices.
  • Contract Testing – This testing method is used for managing the agreements between different loosely coupled units. The dependent units included in the test must use the latest or assigned version of the agreement. The agreement includes information on how various units communicate with each other. 
  • Unit Testing – In this type of testing method, the developers write the tests while the feature or function is anticipated to operate. It assures that software acts coded as a whole.
  • Integration Testing – This testing method involves using service virtualization to simplify and ensure that each component of the software functions perfectly. It also helps to find complications and verifies the interactions between different segments.
  • Component Testing – This testing method concentrates on the operation of the microservice as a black box. It guarantees providing the conditions. Component testing ensues in isolation, where the developers can check the precision and operation of their microservices.
