AndroidTestBuilder

var enable: Boolean

Set to true if the variant's has any android tests, false otherwise. Value is Boolean#True by default.

var enableMultiDex: Boolean?

Sets whether multi-dex is enabled for this variant.

This can be null, in which case the default value is used.

It is not safe to read the value of this property as other plugins that were applied later can change this value so there is no guarantee you would get the final value. To get the final value, use the AndroidComponentsExtension.onVariants API :

onVariants { variant ->
  variant.dexing.isMultiDexEnabled
}

Note the a RuntimeException will be thrown at Runtime if a java or groovy code tries to read the property value.
