Functional Testing

Functional testing checks features and operational behavior of a product to ensure compliance with specifications. This testing ignores the internal mechanism of a system/component and focuses solely on the outputs generated in response to selected inputs and execution conditions. Functional testing usually manual, plays an important role in Business critical applications and in applications where functionalities change quite often.

Manual functional testing is essential, as 100 percent automation is not possible in real-time environment. In an agile methodology, manual functional testing holds upper hand over the automation. Netwin TestCeL has expertise in delivering manual functional testing service on software applications across BFSI, Healthcare, Retail and Logistics, Pharmaceutical domains.

Security Testing

The purpose of conducting security testing is to identify the vulnerabilities and subsequently repairing them. Security testing is performed after the system has been developed, installed and is operational. Unlike other types of testing, security testing is performed on the system on a periodic basis to make sure that all the vulnerabilities of the system are identified.

Performance Testing

Performance is one of the most important aspects concerned with the quality of software. It indicates how well a software system or component meets its requirements for timeliness. Performance testing can serve different purposes like:

  • To demonstrate that the system meets performance criteria.
  • To compare two systems to find which performs better.
  • To measure what parts of the system or workload causes the system to
    perform badly.

Performance testing is the process by which software is tested and tuned with the intent of realizing the required performance. This process aims to optimize the most important application performance trait, customer experience.

Netwin TestCeL’s highly customizable performance testing services help customers quickly detect performance issues prior to implementation.

UI Testing

User interface testing is testing which is used to identify the defects of the product/software under test by using GUI (Graphical Interface Testing). The success of any GUI application depends on how it interacts with user through its user interface, how the user actions are performed to access the application’s features and whether the application responds in a functionally correct manner. An application with incorrect behavior or invalid user interaction can lead to huge problems, here Netwin’s User Interface testing comes into the picture. We have a test team that is experienced in UI testing and is able to assist you in everything that is required.
