After we understand the tests framework, we can start to take a closer look on how native iOS app automation works

Underlying we are using Appium to drive native iOS app automation

• Most concepts are similar for web and app automations, a few things maybe new to people who come from web automation world:

Desired Capabilities

• Desired capabilities are a set of keys and values (i.e., a map or hash) sent to the Appium server to tell the server what kind of automation session we're interested in starting up.
• There are various capabilities which can modify the behavior of the server during automation.
• For example, we could set the platformName capability to iOS to tell Appium that we want an iOS session, rather than an Android one. See the capabilities doc for the complete list of capabilities available for Appium.
• For our sample repo, Desired Capabilities are defined either in profiles in magellan.json file or ./conf/nightwatch.json file. You can specify to use which one in your command line.
• For example, in your command, you can specify it via --profile appium-ios-app, which is defined in magellan.json file.s
