Infrastructure Testing Approach - Part I

Updated: Oct 13

Modern business applications heavily depend on reliable infrastructures. When the organization grows, the IT infrastructure needs to be improved. During such times, the organizations are forced to change their data centers. Hence, the data centers become huge to support organizational needs. However, such changes involve certain risks, for instance, changes in components expose massive risks for our IT services. In such scenarios, testing an application alone will not identify problems in the system architecture. To counter such problems, the organization can take the help of Infrastructure testing method, wherein the Infrastructure testing helps to close this gap and point out problem spots in the hardware, network, and software layers.

What is Infrastructure testing?

Infrastructure testing is part of a test project that helps in identifying and analyzing various risks involved during setting up of target infrastructure for an organization. The projects that usually involve risk are hardware migration, lifecycle management projects, and/or newly built system deliveries.

Infrastructure testing helps in making sure that the IT infrastructure of the company is well designed and placed in accordance with the requirements of the company. It not only makes sure that the IT infrastructure of the company is well set to handle a large amount of data but also makes sure that all the risks are analyzed in well advanced, thereby enhancing the security of the data.


Herein, we will discuss the scope of the infrastructure testing and the steps taken by a testing manager to understand the risks involved in setting up a new infrastructure. The following steps are taken during the infrastructure test:

  • Check the new hardware stack

  • Check the installed software 

  • Check network connectivity (firewall rules working)

  • Check if the new machines are compliant to security standards

  • Check response times

  • Check system resource utilization

  • Check virtualization resources usage

  • Check availability

  • Automated problem detection and alerting

  • Resilience tests 

It is crucial for any organization to make sure that the hardware infrastructure is capable to handle the whole organizational data. If the hardware infrastructure is good, then it will be able to handle software infrastructure, which will help the organization in providing better service to its clients, thereby achieving an overall better user experience.

The Infrastructure-testing project comprises of various layers such as the hardware layer, network layer, software layer, and user experience layer. It is important for the organization to test every layer and make sure that the infrastructure is not having any problems or bottlenecks in any of the layers. Herein below mentioned Figure 1 depicts the pyramid of layers that are part of the infrastructure of the organization.

Infrastructure Testing activities

Various infrastructure testing activities are conducted over different layers. These activities are conducted to make sure that each layer can perform at its best possible condition without causing any risk concerns. 

Hardware/Virtualization Layer Testing With respect to hardware layer testing, the following attributes of the hardware devices are tested:

  • The Capacity of the hardware devices

  • Interfaces available

Network Layer Testing With respect to the network layer, the following parameters are to be considered and tested:

  • Firewall Rules

  • Available Load Balancers

Software Layer Testing With respect to the software layer, the following parameters need to consider and checked:

  • Software Patches available and used

  • Libraries used

  • OS type and version

  • Security Testing for vulnerable components

User Experience Testing With respect to user experience, the following parameters are considered as part of testing:

  • Response times for various queries

  • Resource Availability

  • Reliability

  • 24 x 7 test request execution capability

  • Automated problem reporting

  • Health overview dashboardsPage Break


Before starting with Infrastructure testing, the stakeholders should think about continuous configuration automation (SCM Tools) to automate the setup for Operating System and Software so that the possibility of errors is minimized, thereby reducing Testing and Trouble Shooting overhead for newly provided infrastructure.

To improve the Time to Market factor, unexpected costs and delays in projects should be reduced and quality of delivered infrastructure should be increased. To achieve these objectives, an Automated Infrastructure Configuration Management is required.

Automated Configuration Management is desired for infrastructure provisioning to minimize manual mistakes and speed up delivery of ready to use infrastructure. Responsible Teams for given service layers should evaluate State of the Art Tools like below in Figure 2:
