How do I determine which platform a specific detox test is running on?

Question

When using detox matcher by class name i.e. by.type(className) https://github.com/wix/Detox/blob/master/docs/APIRef.Matchers.md#bytypeclassname

Is it possible to change the classname depending on the platform the test is running on (ios/android)

e.g. element(by.type(className)) becomes:

• element(by.type('android.widget.ImageView')) on android
• element(by.type('RCTImageView')) on ios

Answer 1

Use device.getPlatform() to determine the current device platform.

Documentation: https://github.com/wix/Detox/blob/master/docs/APIRef.DeviceObjectAPI.md#devicegetplatform
