Big DataTesting


We understand that organisations need  big data  testing expertise, which includes 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 for these application types as the manual comparison of source and target data using sampling and aggregated queries are ineffective and time-consuming.
