UNIT Testing is defined as a type of software testing where individual units/ components of a software are tested. Unit Testing of software applications is done during the development (coding) of an application. The objective of Unit Testing is to isolate a section of code and verify its correctness. Managing test cases without any template is quite difficult. ETL Testing; Agile Scrum Tutorial. But using a standard test case format for writing test cases is.

Do you wish to learn and download a Sample Test Plan? This tutorial is in response to those who have requested for a test plan example.

In my previous tutorial, I have outlined the Test Plan Index. In this tutorial, I will elaborate that index with more details.

A Test plan reflects your entire test schedule and approach.

This includes the purpose of a test plan i.e scope, approach, resources, and schedule of the testing activities. In order to identify the items being tested, the features to be tested, the testing tasks to be performed, the personnel responsible for each task, the risks associated with this plan etc.

I have included the link to download a PDF format of this test plan example at the end of this post.

I know several small companies do not do testing on ETL process, but that seems to be suboptimal from the perspective of software engineering.

How do people usually do testing/unit test/functional test on ETL process?

thanks a lot

testing of an ETL is usually a problem. More precisely, testing isnt problem, problem is how to get reasonable test data. ETL is typically tested on production data. Aside of the security issue, the problem with production data is that does not cover functionality of ETL sufficiently (typically about 40% of business rules isnt covered by production data sample) and it takes too much of time to process.

Recently we have developed a test data generator (for more detail, please look for GTL QAceGen: Business Logic Driven Data Generator on Informatica Market Place) which generate test data based into source tables/files on business rule specification. Tool takes into consideration any foreign key applied and it works for any major ETL and/databases.

This tool helps to speed up testing cycle by at least 50% (compared to manual testing) an covers 100% of all business rules. It also generates quite detailed reports and more importantly, these tests can be repeated at any time (ie regression tests).

Etl Testing Tutorial

We recently worked on a project where the governance board demanded 'You must have Unit Tests' and so we tried our best.

What worked for us was have each ETL solution start and end with a QA/Test package.

Anything unexpected discovered by these packages was logged into an audit table and a Fail Package event was then raised to stop the entire Job - We figured it was better to run with yesterdays good data than risk reporting against possible bad 'today' data.

The starting package would do db schema and data sanity checks. Data Sanity involved checking for duplicate or missing data caused by a lack of Referential Integrity in the source systems. Schema checks ensured that any schema changes that did not get applied during Continuous integration were detected.

The end package would check the results of any transformations. These included:

  • Comparing record counts between source|destination
  • Checking specific transforms (eg: all date values changed to appropriate SK value, all string values RTrimed)
  • Ensuring all SK fields were populated (-1 instead of nulls)

Most of these tests were SQL statements the used the built in schema objects of our database, so they were not to onerous to create.

In addition, as part of our development process we would create views that had the end result of any transformations we were doing. We would make use of these views to validate our package transformations.

Each of these checks created a record in our special audit table. That way we could provide a comprehensive list of all the tests and checks we had done each running of the process to satisfy the governance peoples.

(We also had a separate set of packages that would unit test each QA test by means of creating dummy tables, populating them, running the test then confirming the appropriate audit record was written. As Nick stated, this was a lot of work and of little real value)

We've set up a system where for each ETL procedure we have defined an input dataset and an expected result dataset. Then we have created a system which, utilizing Robot Framework, runs three-part tests for each ETL procedure where the first part inserts the input dataset into the source data tables, the second part runs the ETL, and the third part compares the actual results with our expected results.

This works pretty well for us, but there are a couple of downsides: first of all, we create the test datasets manually for each ETL procedure which takes some work, and secondly, this means that testing for 'unexpected' inputs is not done.

For the automated unit testing we have a separate environment in which we can install builds of our entire DW automatically.
