What is the basic requirement for writing the Appium tests?

The Basic requirement for writing the Appium test are given below:

• Driver Client: Mobile applications are being driven by Appium. We can use the client library to write our Appium tests and then it wraps our test steps and sends it to its servers over HTTP.
• Appium Session: We need to initiate this process by creating a session as such tests take place in a session. For one session, it can be ended once the automation is completed and then we need to wait for the next session.
• Desired Capabilities: Certain parameters need to be followed while creating an Appium session which is also known as desired capabilities: Platform Version, Platform Name, and Device Name. It helps in the selection of which type of automation is required from the server of Appium.
• Driver Commands: We can write our test using expensive and large commands vocabulary.
