Selenium Framework Design in Data-Driven Testing

Single mobile device nodes

For mobile simulators and emulators, it is recommended that only one instance is run on a node at a time. They are very slow and memory intensive and perform poorly using the Appium server technology. Using Linux for Android emulator platforms is much faster than Windows-based emulators, though. However, there really is no limit on how many physical devices can be installed on each mobile node, it just makes sense to only run one instance at a time.

Here is a design to support single mobile device testing per node:

Set up each node to only create instances of one mobile emulator/simulator type. For this scenario, you would need eight VM nodes, as follows:

• Linux/Android phone emulator x 1 instance
• Linux/Android ...
