Big Data Testing

We understand that organisations need big data testing expertise, which include the areas of data warehousing, business intelligence and data integration/ETL. It is time-consuming to familiarise testers with the domain knowledge and specific testing techniques required to effectively test these application types. Our specialised testing services fill the niche requirements in this area.

While Agile and DevOps practices enable faster release cycles and increased responsiveness to changing business needs, teams do struggle to maintain quality levels. More effective testing by means of test automation, shift-left testing and test environment management can provide the much needed balance between speed of delivery and quality.  At busii we focus on these practices in providing effective testing services.

For example, we make extensive use of bespoke, open source-based test tools to automate various aspects of testing big data applications. Tool use for test execution is especially necessary in these application types as manual comparison of source and target data using sampling and aggregated queries is ineffective and time-consuming.

We use test tools for several different purposes, including:

  • 100% detailed business rule and data coverage in source-to-target testing
  • On-the-fly test coverage analysis as test cases are added
  • Comparison of various artefacts including:
    • functional specifications against generated code/data
    • software and data across environments – development, QA and production
  • Automated posting of test run results to a test management tool
  • Automated test suite runs for regression testing

We offer:

  • Data migration testing – whether for Salesforce migrations, database upgrades or other forms of data migration. See our data migration reference.

  • Data warehouse testing; Business Intelligence testing; ETL testing – we have extensive experience in these application areas, helping some of South Africa’s largest companies to balance time, cost and scope in delivering quality solutions
