Q4. What are the limitations of using Appium?

Answer:
The below list are the limitations of using Appium but are not exhausted :

• It requires a minimum Android version of 4.2 or above to work with the mobile testing application.
• It has limitations in supporting the testing of hybrid apps.
• The functionality of adding inspector feature is not available in the Windows operating system.
• It is not easier to perform testing on larger applications in the early stages. It can still be implemented slowly in the later stages by gradually writing test cases for the smaller modules.

Q5. What is the architecture of Appium and its design features and functionalities?

Answer:
The architecture of the Appium includes different components such as HTTP Server, Node platform etc. The HTTP server for the Appium will be on top of the Node.js platform. Node.js handles the sessions of the iOS and Android sessions using the Web Driver wire protocol (JSON). Different client libraries are written using programming languages such as JavaScript, PHP, Python, Ruby, and C# etc.; The Appium servers establish the connections using the REST APIs from the clients. The automation testing will be carried out in a session. The responses will be in the form of HTTP formats.

Part 2 – Appium Interview Questions (Advanced)

Let us now have a look at the advanced Appium Interview Questions.

Q6. How will the tests be carried out or run on Appium?

Answer:
The tests can be carried out by using Simulators or Emulators. The devices can be emulated over the computer, and testing can be carried out using different libraries or development kit studios. Even the devices can be disconnected from the emulators, and this cannot be a limitation. The running time of the tests would be slow as the devices may run slowly due to the emulations and also due to the consumption of a lot of memory in the device. During the execution of the tests, the behaviour may be unexpected due to the consumption of memory.

Q7. What are the different testing frameworks supported by Appium?

Answer:
The Appium tool supports different testing frameworks, and it will not have any kind of default or inbuilt support to any testing framework and needs configuration or integration of the external testing framework based on the architecture and integration capability of the Appium. The different testing frameworks being support by Appium are Selenium Web Driver, NUnit, .NET frameworks etc.; Appium will provide the driver modules to write the test cases.

Q8. What are the requirements for writing the Appium test cases?

Answer:
The different elements or important components of the Appium test cases are Drivers, Session, Capabilities, and Commands. The Driver module provides different APIs to write test cases in Appium. All the test executions require a session for the execution of each test case or test suite. The different capabilities like Platform details, device details and a few other details to start the execution. A different set of rich commands exists in the Appium tool to write and execute efficient tests.
