Big Data Testing

Big Data Testing

Big Data is growing at a rapid pace and with Big Data comes bad data. Many companies are using Business Intelligence to make strategic decisions in the hope of gaining a competitive advantage in a tough business landscape. But bad data will cause them to make decisions that will cost their firms millions of dollars.

According to analyst firm Gartner, the average organization loses $14 million annually through poor Data Quality, with 22% estimated their annual losses resulting from bad data at $20 million and 4% put that figure as high as an astounding $100 million. Yet according to the Experian Data Quality report, 99% of organizations have a data quality strategy in place. This is disturbing in that these Data Quality practices are not finding the bad data that exists in their Big Data.

Big Data Testing Challenges

Typical testing around traditional data warehouses or databases revolve around structured data and using SQL to accomplish the testing. Big Data testing is completely different. 

Below are some challenges of testing Big Data:

  • The volume of data can be overwhelming
  • Big Data testing is very complicated and requires experienced and highly skilled testers
  • Testing of structured, semi-structured and unstructured data is complex
  • Hadoop testing typically relies on HQL, relegating the 2 data testing main methods, Sampling (also known as​“stare and compare”) and Minus Queries, unusable
  • Testing is complicated when dealing with security systems like Kerberos
  • Testing infrastructure requires a special test environment due to large data size and files (HDFS)​
