Training days
  • 13 & 14 June (2022) 09:00-17:00 CET

After having drawn a common view on the world of Data & Analytics by exploring the concepts of Business Intelligence, Data Warehousing and Data & Analytics, we’ll dive into testing and test processes, focussing on the specifications required when testing data and analytics solutions. ​

We’ll explore Risk Based Testing and the special skills that are required testers dealing with data and analytics.

We will tackle the concept of how to test reports and dashboards, completeness, data quality as well as testing business rules and ETL (extract-, transform and load).

​We will explore differences between data & analytics testing and conventional testing, the specifics of Test Environments when dealing with Data & Analytics, Test Data, Ethics and Privacy Law (e.g. GDPR).

Participants learn how to apply Data Profiling in order to create better test cases and to cover the most relevant Data Quality attributes.

This training will prepare candidates for the DAU Certified Data & Analytics exam, which can be taken (online or paper based) through Brightest. One exam voucher is included.

This is an English spoken training, so general knowledge of business English is required.  Testing knowledge or even certifications like ISTQB CTFL are not required, though they will make it easier for you to understand the testing approach and – designs. Basic knowledge of business intelligence and data warehouse concepts is welcome. We’ll use the first hours of the training to create a common ground regarding the definitions.

EUR 1.195 excluding VAT
– incl. exam Voucher
– incl. Lunch.

    Data & Analytics Testing Tools Summary (1)


    During the training Certified Data & Analytics Tester (Foundation Level) we provide a list of tools that can be used in testing or monitoring Business Intelligence and Data Warehouse products.

    Below you can find the first 4 tools of this list, with a short description and links to the tool providers.

    We are curious for your experiences when using these tools. What have they brought to your (testing) team? What is a Big Plus of using the tool – and with which features are you less impressed? Is an active user community available, or a help desk that makes a difference? Please let us know, by leaving a message under this post, through the Contact Form, LinkedIn or Twitter.

    Note: We are not being sponsored by one of the products or their integration partners.

    Data Cleaner

    Data Cleaner is software which is used for Data Profiling.

    It can also be used in the process of creating logical and physical test cases as it offers extensive support to analyze and browse through data sets.

    Data Cleaner also offers features to clean, transform and export data sets. Rules can be built and reused.

    Data Cleaner is free, additional (paid) features are available.

    It can be downloaded to your desktop (Windows, Mac) environment from sourceforge or the community website:


    SAS Unit

    SAS Unit is a framework for the unit testing of SAS programs (SAS EG 9.2, 9.3, 9.4).

    Amongst others, SAS Unit offers features to assess test coverage of SAS Macros, running tests in batch mode, performance testing of SAS programs.

    SAS Unit uses assertions to test the values of macro variables, contents of SAS data sets, relations between data sets, the existence of files incl. log files and – messages.

    SAS Unit is open source software and built from SAS macros.


    Informatica DVO

    Informatica offers a testing solution called Data Validation Option for PowerCenter (DVO).

    The DataValidator for PowerCenter product was originally developed by a company DVO SOFTWARE. It is now available under the Informatica brand as Informatica PowerCenter Data Validation Option.

    DVO is a custom tool built on top of Informatica PowerCenter. DVO integrates with the Informatica PowerCenter Repository and Integration Services and enables developers and business analysts to create rules to test the data being transformed during the data integration process.

    Informatica mentions the following ETL Testing Use Cases: Production Validation Testing, Source to Target Testing and Application upgrades.

    Amongst others, it features:

    • An easy-to-use GUI interface to test the rules created for data validations for multiple projects.
    • No programming skills needed to create validation tests.
    • A repository with reporting capabilities to provide a complete audit trail of all tests and their results.
    • Reading data definitions from PowerCenter metadata repositories and can easily deal with data definition changes.

    Note that DVO tests data only, not mappings or workflows. Testing mappings is unit testing, which is different from data validation.

    As DVO is a commercial product it may be attractive to Informatica Power Center users. At this moment, no free trial seems available (Feb 9, 2020).

    Workshop “Data Quality” op Testnet Voorjaarsevenement 2016, Houten

    Op woensdag 11 mei 2016 vindt het Voorjaarsevenement van Testnet plaats. Van 09:00-21:00 uur zal het NBC gevuld zijn met allerhande soorten testers, voor het delen van ervaringen en het opsnuiven van nieuwe kennis.

    Armando Dörsek zal op deze dag met Peter Endema een workshop verzorgen: Data Profiling voor Testers.

    De workshop vindt plaats tussen 15:40 uur en 17:20 uur. Neem je eigen laptop mee!

    Na enige uitleg door Armando over oorzaken en gevolgen van data issues  neemt Peter de deelnemers mee in het geautomatiseerd analyseren van datasets middels een open source data profiling tool. Testers leren hiermee nieuwe vaardigheden waarmee ze eerder in het traject betrokken zullen worden en die hen nog waardevollere teamleden maakt.
