We provide ETL testing online training ETL stands for Extract Transform and Load. ETL can be treated as wider and broader horizon of normal testing that is done for business applications. Technically the process remains same as is there in any other kind of testing. First and foremost step is to understanding of requirements and business.
Once the requirements are well understood and business concepts are clear, it needs to be mapped various aspects like what is there at presents, what is required, in what timeframe and with what kind of resources. In fact once the requirements are clear as well the business goals are understood, one needs to validate and get them vetted by the respective process/business owners. After this estimation needs to be worked out on the basis of timelines being proposed to be consumed.
