Our ETL Testing Process

At getSmartcoders, we follow ETL Testing Process to guarantee quality assurance. Our ETL Testing Process involves the following steps:

01 Requirement
Requirements for mobile app development

This is the first step in ETL testing process. We sit with you to understand your requirements. The primary task in this step involves identifying data sources, implementing the data profile, and define data quality criteria. At the same time, we try to gain an understanding of your business goals and objectives. Once we gather all information, we finalize the project milestone and project timeline with you.

02 Validate
Data Sources
Design the UI UX of mobile app

After understanding the testing requirement, we analyze and validate it from a technology perspective. In this stage we primarily carry out a data count check and make sure that the data types meet all the specifications of the data model. We also ensure that the data is thoroughly cleaned, and duplicate data is completely eliminated. We do this as precisely as possible to ensure the aggregate report is accurate and reliable.

03 Test Data
Development of mobile app

Our next step is to select the accurate test datasets and establish the right data combinations. To carry this out we design ETL mapping scenarios, develop SQL scripts, and frame the transformational rules. Once all of these are ready, we validate the mapping document and ensure it contains all the information necessary to carry out the testing effectively. This step serves as a launching pad for ETL testing.

04 Test
Testing Process of mobile app

In this stage we execute ETL tests as per business requirement. While testing we identify types of defects or bugs encountered and prepare a report. Thereafter, we fix the bug, rectify the defects, and close the bug report. During the course of test execution, we apply business transformation logic and sort the data for further testing, such as indexing and data partition.

05 Verification
and Load Data
Deploy mobile apps for go live

This is an important step that involves correct data mapping and verification of all measure groups. This is followed by moving the data from staging to the data warehouse. We perform a record count check before and after moving the data. This helps us to verify that invalid data is weeded out, and default values are accepted.

06 Summary
Support and Maintenance of mobile apps

This is the final step of the testing process. In this step we verify layout, options, filters, and export functionality and prepare a detailed summary report. The report is customized as per client specific need so that stakeholders/decision-makers know the details and outcome of the testing process. The report may also contain the reason for eliminating a step if it was not carried out.
