TESTINGS FOR ARCHITECTURES BASED ON MICROSERVICES

MICROSERVICES

The challenge currently faced by technology areas to respond faster and faster to business needs has triggered a series of changes. This includes one that is almost invisible to the human eye, but decisive when it comes to scaling efficiently: architecture based on Microservices, which is also characterized by its agility and flexibility, attributes that respond to the modern dynamics of businesses in any sector.

Although this type of architecture based on MicroServices provides great benefits, it also involves the implementation of cutting-edge technology practices such as continuous delivery (DevOps), automated infrastructure, testing and assurance of quality assurance, for which we have prepared ourselves at GreenSQA by defining strategies adjusted to this need.

REMARKABLE BENEFITS OF
MICROSERVICE ARCHITECTURES:

SELF-RELIANCE

Each Micro Service is an executable in itself and can be deployed without affecting the rest.

GRANULARITY

It improves the understanding of the applications, since the business logic is decoupled, as MicroService is in charge of a single functionality.

MODULARITY

It facilitates the development of software in distributed work teams, as well as the possibility of expanding or reducing depending on the needs.

SCALABILITY

They allow each service to be scaled independently to adapt to specific or seasonal traffic peaks.

OTHER RELEVANT FEATURES OF MICROSERVICES:

  • They can be written in different programming languages.

  • Each micro service can be housed in a container.

    It is implemented as a virtualized operating system that contains everything needed to deploy the service.

  • Access to MicroServices

    Microservices can be accessed through a GATEWAY API component, which acts as a proxy, with authentication functions, caching, usage fee management, metrics generation, etc.

  • Each one has its own access to the database.

  • Communication is usually done over HTTP protocol via API

There are MicroServices that manage generic functions for the application, for example: database access, file loading, logs generation, etc.

At GreenSQA we offer complete and innovative solutions for testing and quality assurance of applications with MicroService architectures.

THE CHALLENGE OF TESTING AND SECURING
APPLICATIONS WITH MICROSERVICE ARCHITECTURE

Pruebas de Software Calidad de Software GreenSQA

Our challenge at GreenSQA has been to define a new strategy to test and ensure the quality of applications with microservice architecture, which beyond the individual testing of each MicroService, allows us to test the integration of them and most importantly, test and ensuring data consistency.

Our approach allows us to verify the information at all communication points, as well as the functionality of all MicroServices.

TESTING TYPES FOR
MICROSERVICES:

The types of tests that should be taken into account for the implementation of these MicroServices are the following:

UNIT MICROSERVICE TESTING

To verify the call and response of the MicroService, the consistency in the types of data, order, and completeness of the same.

MICROSERVICES FUNCTIONAL TESTING

To verify the behavior of the MicroService implemented from its methods. This verification is done through the generation of possible scenarios that the service uses.

MICROSERVICES NON-FUNCTIONAL TESTING

Its objective is the verification of the response times and the performance of the MicroServices. In addition, an availability testing is recommended. Response times are monitored on the service bus, according to the range.

TRANSACTIONAL SYSTEM TESTING

The purpose of this test is to test the transaction from the mobile application to the application of the movements in the sender and receiver´s accounts of the transfer.

At GreenSQA we have the knowledge, tools and an Agile and guaranteed process to test MicroServices.

An example of our experience was the recently developed project with one of the most renowned aviation companies in Latin America, Avianca.

It consisted of the implementation of the CRM-Dynamics system as a technological platform to support customer relationship processes, whose integration was implemented using MicroServices architecture.
