When an application or a software or a website is developed, then there are several components of it. Those components can be server, database etc. The connection which integrates and facilitates the communication between these components is termed as an Interface.
Interface Testing is performed to evaluate whether systems or components pass data and control correctly to one another. It is to verify if all the interactions between these modules are working properly and errors are handled properly.
Interface Testing - Checklist
- Verify that communication between the systems are done correctly
- Verify if all supported hardware/software has been tested
- Verify if all linked documents be supported/opened on all platforms
- Verify the security requirements or encryption while communication happens between systems
- Check if a Solution can handle network failures between Web site and application server
Phases of Interface Testing.
There are 2 components involved in Interface testing: 1) web server and application server interface and 2) web server and database server interface.
Basically, 3 phases are involved in the Interface testing which is mentioned below:
Configuration and Development. After the configuration of the interface and the development initialization, the configuration is needed to be verified as per the requirement. In simple words, verification takes place.
Validation. After the configuration and development stage, validation of the interface is necessary.
Maintenance. After the completion of the project, when the project reaches it’s working stage, the interface is set to be monitored for its performance.

F.A.Q. about Interface Testing
Types of Interface Testing
During Interface Testing various types of testing done on the interface which may include:
Workflow: It ensures that the interface engine handles your standard workflows as expected.
Edge cases -unexpected values: This is considered when testing include date, month and day reversed.
Performance, load, and network testing: A high-volume interface may require more Load Testing than a low-volume interface, depending on the interface engine and connectivity infrastructure.
Individual system interface testing: This includes testing each system individually. For example, billing system and inventory management system for the retail store should be able to operate separately.
What is Graphic User Interface (GUI) Testing?
Graphic User Interface Testing (GUI) testing is the process of ensuring proper functionality of the graphical user interface (GUI) for a specific application. This involves making sure it behaves in accordance with its requirements and works as expected across the range of supported platforms and devices.
GUI Testing Approaches
Manual Based Testing: Under this approach, the screens of the application are checked manually by testers. They are being confirmed with the requirements that are stated in the business requirements. The UI is also matched with the designs that are provided during the documentation phase of the application.
Automation Based Testing: Automated user interface testing approach is performed in 2 steps i.e, record and play. While doing this, the steps are captured/recorded with the help of the automation tool while performing the first round of testing. And during playback, that recorded steps script is run when the application is under test. If the position of any button or image changes that during the playback, it does not get tracked and the test fails.
What Features Should I Look for in a GUI Testing Tool?
Obviously the first answer is to choose a tool that can automate the specific technologies you’re testing, otherwise your automation is doomed to fail. Secondly you should choose a tool that has some of the following characteristics:
- Good interface testing software that makes it easy for your automation engineers to write tests, make changes, find issues and be able to deploy the tests on all the environments you need to test.
- A tool that is well supported by the manufacturer and is keeping up to date with new web browsers, operating systems and technologies that you will need to test in the future.
- An object abstraction layer so that your test analysts can write the tests in the way most natural for them and your automation engineers can create objects that point to physical items in the application that will be robust and not change every time you resort a grid or add data to the system.
- Support for data-driven testing since as we have discussed, one of the big benefits of automation is the ability to run the same test thousands of times with different sets of data.
