CASE STUDY
Building a Custom Automation Framework
with Microsoft Visual Studio Coded UI
Background
Our client needed an automation solution to perform regression
testing on their new data forecasting .NET application, which
used third party Infragistics controls extensively. After having
their in-house resources try to implement a functional test
automation tool unsuccessfully, the company sought a trusted
vendor with the expertise to automate the testing of their new
application.
They required proven expertise in test automation and the ability
of an engineer to work as an extension of their team on-site. Our
client contacted us to assist in this new undertaking, and they
were looking to use Visual Studio’s Coded UI tests to automate
their new application.
Challenges
The challenge of the previous test automation effort was that the tool used was not able to recognize
the Infragistics control. This posed a significant issue for the project, and the client’s team first tried
to compensate for the object recognition problems using the testing tool’s pixel matching capabilities
to navigate and collect data from the Infragistics controls. This led to inconsistent test runs and
continuous maintenance problems with the automated tests that were created.
They realized that they were in need of a consulting vendor that had experience with a functional
testing tool which could recognize the Infragistics objects. In addition, the complexity of the
application’s user interface meant that the client would need a test automation framework that would
allow their resources to easily create and maintain tests.
RTTS' Strategy
We worked with the client to determine their exact needs, and then sent over a member of the RTTS
team to implement Microsoft Visual Studio Coded UI tests to automate their data forecasting
application.
Infragistics provides an add-on to Visual Studio that allows Coded UI tests to recognize the
Infragistics controls. Therefore, we came up with a strategy to use Coded UI to build out a
comprehensive framework and to make test creation straightforward and easy to maintain. Our client
had a few team members that were experienced in the C# programming language but had no
experience with Coded UI tests, so once a framework was in place with sample tests created, we
formulated a strategic transition plan to show the client how the framework can be modified and how
tests can be created using that framework.
Solution
We created Coded UI tests for two of their applications that were used for Inventory Forecasting. We
also designed custom-built reusable navigation methods that allowed for seamless creation of new
Coded UI tests. These methods presented enhanced functionality when working with every type of
Infragistics control. They were designed to be used in any test and provided immediate benefits to
our client’s team. All of the methods that were developed (along with detailed descriptions,
parameters, and notes) were compiled into a comprehensive help file that was made to function as a
resource for the client’s team moving forward.
In order to ensure knowledge transfer after the conclusion of our engagement, we hosted training
sessions for the client’s team where we illustrated how the methods were used and how they can be
customized as their project expands. We first delivered a formal class in the Coded UI test basics
over the period of two days. Two additional days were dedicated to reviewing the specific features
that were needed to handle the unique challenges in working with their application.
Benefits
The client’s new automation framework now allows them to easily build and maintain functional
Coded UI tests for their application. Their team has the knowledge to create new Coded UI tests and
self-maintain their existing regression suite. They have been able to drastically reduce test creation
times by using the framework we built for them. This framework is now being used to access and
manipulate all the Infragistics objects that are used in their application.
