Big Data Testing Services

The incredible eruption in the IT urge, data volumes, velocities and varieties have created intensified concerns over how to guarantee quality across the big data & data analytics ecosystem.

A meticulous testing approach is essential to offer impeccable quality in big data & data analytics testing. Indium will intensify your testing speediness, improve your testing exposure (up to 100%), and increase the level of excellence within your Big Data store.

With the increasing challenge of storage, processing, and accessing the data, Indium understands that Big Data testing is hard to do without the right tools and technologies.

Indium software offers a broad spectrum of big data analytics testing services including,

Big Data sources Extraction Testing
Data Migration Testing
End-to-End Testing
Data Quality in Big data
Security and Performance testing
Big data Ecosystem Testing

Since Bigdata testing deals with huge amounts of data, which is mostly in terabytes, we use the following strategies in data validations.

Batch Data Processing Test

This test involves testing processes in which the data is run when the application is in batch processing mode. Batch processing storage units such as HDFS are used to process the application.

Real-Time Data Processing Test

In this type of testing, we work with data when it is in real-time processing mode and test the resultant process rules. Real-time processing tools like Spark are used to run the application.

Interactive Data Processing Test

In this type of testing, we simulate a real-life user by integrating real-life test protocols that interact with the app. Tools like HiveSQL are the processing tools used in the interactive data processing mode.

Big Data Testing stages

Our general approach to test a Big Data Application involves the following stages.

Data Ingestion Testing

Our data Ingestion testing practice involves importing, transferring, loading and processing of data to store in the database. The input data source varies from CSV, Sensor logs, social media etc.


Data Processing Testing

Our focus in this stage is on aggregated data. We validate the business logic of the ingested data for correctness. It is further validated by comparing the input files with the output files.


Data Storage Testing

We verify whether the output data is precisely loaded into the warehouse by evaluating the warehouse data with output data.

Performance Testing

Since Big data involves processing of significant amount of data in a short span of time, Performance testing is recommended to avoid bottlenecks.

  • Data Loading and Throughput – It is important to monitor the speed at which the data created in the data store and data consumed from various sources.
  • Data Processing Speed

Sub-System Performance – The individual components of the overall application is tested here to identify possible bottlenecks

Functional Testing / Integration Testing

The complete front end of the application will be tested from data visualization to data ingestion. We test the front end of the application according to the user requirements.


Data Quality Testing

The output is usually stored in HDFS or any other warehouse. We compare the output data with the data in the warehouse and ensure that the data was loaded correctly in the warehouse.


Data Migration Testing

We can migrate data from an old system to a new system and ensure that there is no downtime and zero data loss with our data migration testing.


Business logic Validation Testing

We ensure that the business logic is implemented correctly when the ingested data is processed. We further validate this via comparison of the output and input files.
