Big Data Automation Testing - Needs & Challenges
Testing Big Data applications requires a scientific temperament, analytical skills, and deep and practical understanding of data science. Following are a few needs and challenges that make automated Big Data testing a must.
- Increasing need for live integration of information: Enterprises need to have constantly clean and reliable data. This can only be ensured through end-to-end testing of the data sources and integrators.
- Instant data collection & deployment: Simply deploying the data isn’t enough. Enterprises need AI-based predictive data analytics testing to effectively take Decisive Actions by analysing the insights from the minute patterns in large data sets. Unless the apps & data feeds are tested & certified for live deployment, correct decisions cannot be made.
- Migrating legacy to new systems: While migrating data from legacy systems, there are high chances of disruption/downtime, data integration challenges, and loss of data. Data Migration Testing helps verify all functional & non-functional aspects of the app post-migration.
- Real-time scalability challenges: Big Data apps need to match the level of scalability & data processing involved in a given scenario. Any error in the architectural elements of Big Data apps can lead to severe business impact. Software testing involving smarter data sampling, cataloging techniques, & high-end big data performance testing capabilities are thus critical to meet the scalability problems of Big Data apps.

Data Integration - Drawing Large & Disparate Data Sets Together in Real-Time
Current data integration platforms which have been built for an older generation of data challenges, limit IT’s ability to support the business. In order to keep up, enterprises need to look at next-generation data integration techniques & platforms such as API testing & validation of business rules, outbound interfaces & downstream data.
They need to perform end-to-end system testing & integration testing, and develop the ability to understand, analyze and create test sets that encompass multiple data sets. This is vital to ensure comprehensive Big Data testing, data analytics testing, visualization testing, and data migration testing.
