Software Testing


Software testing is an integral part of the software development process. For every code change made, every line updated, there are multiple testing steps to ensure its validity. Long before the code is released, it is put through a rigorous exercise routine and in various environments.

First the code is reviewed by another developer. This is called ‘peer review’. By doing this more than one set of eyes are lent to the line changes or updates. This serves two purposes as it allows for double checking the work, but also an opportunity to learn from each other.

Once the code has been reviewed, it is built into a development environment. This is where it is tested for the application. Changes in the code are tested for compatibility with the platform. This lets us know that the updates are fully compatible and did not conflict with any of the existing code. When the development environment testing is completed, the code changes are approved and the code is then pushed to a QA environment.

In the QA environment, the same testing is done but on a larger scale. Many more sets of eyes can view and review the QA environment. This allows for a more thorough testing platform across the board. The code will stay in the QA environment for anywhere from a week to two weeks depending on the type of code it is or the need for more extensive testing.

Once the code has passed QA testing, it is then pushed to a sandbox platform. This platform is our general beta platform in which clients and companies may test our software. Again it is available for a broader testing scope. The code will stay in sandbox for approximately two weeks before being pushed to production.

If any errors or defects in the code are found during this process, the code is pulled down from the testing platform and corrected. After which the testing routine starts all over again.

For back end code that is updated or changed and has passed peer review but is not available for UI testing, the testing process is slightly different. The code is initially processed through a what are called unit tests and SOAP tests. These tests allow the developers to know if the code written will perform as expected. These tests are generally used for SWS and method updates and are generally not tested in the same way as UI changes would be. The unit and SOAP tests target the specific SWS or method code identifying the parameters and string types. The code is then tested to ensure it calls and returns the correct data.

Once the back end code is tested and verified, it then follows the same testing flow from development to production as any other code. The SOAP and unit testing is repeated in each of the platforms by many different sets of eyes. This again allows for more thorough testing. If at any time data is not returned correctly, the code is pulled, re-written and then tested all over again.
