Full cycle testing includes all aspects of functional, non-functional, unit, integration, performance and regression testing both manual and using open source automation tools and technologies such as Selenium, SOAPUI, Gatling, Supertest, Nightwatch, Cucumber, and custom programming as needed. Different testing strategies need to be applied for monolithic and microservice based architecture.
Testing for Layered or Monolithic architecture: V-model verification and validation process is involved that covers different testing mechanism at different stages as follows:
Testing for Microservice architecture:Pyramid model is more effective when testing microservices due to their decentralized nature that provides loose coupling and high cohesion. This model involves testing at different stages as follows:
Products and applications are being built using polyglot persistence that involves multiple SQL & NoSQL databases to solve a use case. Testing on such diversed persistence storage systems involve good knowledge of SQL to perform complex queries on RDBMS and database proprietary query languages for NoSQL. The following tools and query languages across different databases need to be mastered to perform high quality testing:
MySQL/Oracle/Postgres: Testing using complex SQL queries, validating stored procedures, triggeres, functions, and views, checking constraints and referential integrity, and verify database schema with the reference model for data types, data length, character set, etc..
NoSQL: MongoDB query language to verify JSON documents and collections, CQL for Cassandra, Cypher QL for Neo4j, OrientDB SQL to verify nodes and relationships in OrientDB, Lucene queries to verify documents in ElasticSearch, and others
Tools:Tools such as Compass, Metabase, Talend, Zeppelin, Jupyter, and programming languages like Python and Java are extremely useful while dealing with hybrid database systems
Big Data Testing is the most complex testing process due to huge volume of data flowing thru the system that are processed by multiple tools and technologies from ingestion to analytics. It’s very important to understand the source of the data, multiple transformation and filtering process it goes thru, identifying data lineage graph, different calculations and aggregations performed on the data, and have data sense towards outliers.
Tools and technologies such as Talend, Zeppelin, Jupyter, and decent query abilities on Hive and SparkSQL are necessary to perform testing on Big Data that should cover entire data pipeline as below:
Continuous development, integration, and deployment with containers on cloud using Agile iterative principles is the proven combination for faster time to market. Testing different moving parts at a fast rate in less than 2-week sprint cycle needs different testing strategies on top of regular full cycle testing such as below:
A web application can be opened in different devices, browsers, operating systems, and so on by an end user. Cross-browser testing or browser compatibility testing is needed to ensure that the application works as expected in all browsers. This includes testing in both client and server sides. read more

Microservice architectures enforce clearer, more pronounced internal boundaries between the components of an entire system than monolithic applications typically do. This can be used to the advantage of testing strategies applied to microservices; more options for places and methods to test are available. Because the entirety of the application is composed of services with clear boundaries, it becomes much more evident which layers can be tested in isolation. read more
