WHAT ARE BIG DATA TESTING SERVICES?

Big data means a vast volume of data that comprises both structured and non-structured data extracted from several sources.

Through the help of big data, businesses can analyze the customer’s behaviours and even understand the market trends, which helps them modify their offerings and products as per the customer’s expectations. Hence, for this reason, big data analysis is crucial for businesses.

An exceptional eruption in the IT urge, data volumes, varieties, and velocities has aroused several concerns over how businesses can ensure quality across the big data and data analytics ecosystem.

Hence, to deliver the right and appropriate insights, it’s crucial to ensure that the big data application that the businesses are using is error-free, bug-free, and valid. So, when you require impeccable quality in your big data and data analytics, you have to ensure the proper testing approach of the data analytics and big data testing services. Such services can ensure that your big data and data analytics are valid, secure, and without errors.

There has been an increase in the challenge of processing, storage, and accessing the data.

STRATEGIES IN DATA VALIDATION THROUGH OUR BIG DATA TESTING SERVICES:

We provide exceptional testing strategies for the efficient and effective testing of your big data application since big data testing services usually deal with vast volumes of data, primarily in terabytes. The strategies that we use in data validations include:

  • Batch Data Processing Test involves testing processes where the data gets executed while the big data application remains in the batch processing mode. Batch processing storage units such as HDFS are utilized for processing and data storing.
  • Real-Time Data Processing Test: It’s a test strategy where we work with the data while it’s in the real-time processing mode and then validate the resultant process rules. We execute the application with the help of real-time processing tools such as Spark.
  • Interactive Data Processing Test: This test strategy simulates real-life user behaviour by integrating real-life test protocols that interact with the big data application. In this mode, we use tools such as HiveSQL.

THE STAGES OF OUR BIG DATA TESTING SERVICES:

Vihat Technologies is an offshore big data testing company in India that provides exceptional services to test your big data application. We offer a generic approach for testing your big data application, which involves the following stages:

Stage of big data testing services
  • Data Ingestion Testing: It involves loading, transferring, importing, processing, and reviewing data that is to be stored in the databases. The input data source varies from regular flat files, sensor logs, CSV files, and social media files like videos and images.

             Tools: Kafka, Apache Zookeeper, Sqoop

  • Data Quality Testing: The output data usually gets stored in HDFS or any other warehouse tools. We can verify the output data results and the data present in the warehouse to ensure that the data got loaded correctly.

             Tools: Amazon S3, Hadoop HDFS

  • Data Migration Testing: Data migrates from an old system to a new system and ensures that no downtime is present and no data loss occurs during the migration.

             Tools: CloudDX, Talend, Pentaho

  • Business Rule Validation Testing: We verify that the business logic gets implemented correctly and appropriately when the ingested data is processed. We take this verification further by comparing input and output files.

             Tools: HIVE, MAPR, Apache Pig

THE PROCESS OF OUR BIG DATA TESTING SERVICES:

We are an offshore big data testing company in India, having experienced and knowledgeable professionals. We have high-end tools and effective testing strategies for your big data application’s efficient and reliable testing. Our big data testing processes include:

INITIATION

In this stage, we initiate the task by analyzing requirements regarding the big data application. A big data application specification document helps us in the analysis process as an initial part of our services.

Planning

In the planning stage, we write a precise, clear test strategy and test plan based on the initiation process regarding the analysis of requirement specifications. They serve as a guideline for all the testing processes, schedules, test coverage, etc., throughout the entire big data application development and testing life cycle.

Test Design

In this stage, we start with the test design, which includes writing and reviewing repeatable test cases according to the requirements determined in the document. Where appropriate, we also focus on non-functional requirements, existing rules, or application logic while writing test cases.

Test Execution

In this stage, we execute the test cases and detect any bugs or flaws to identify if the requirements are as expected. Here, we also participate in a bug triage meeting to identify and prioritize the most critical defects, along with less critical bugs and gaps. We also get the agreed defects fixed and re-tested before the next testing cycle.

Reporting

In this stage, we cluster the bugs based on the impact, priority, and severity and report the bugs, test cases, and test cycles as part of our services.

Results Analysis

In this stage, we analyze the testing reports and discuss with the team the root cause, improvement area, and action plan.
