Easy way to make a mock with settings

Is there an easy way to include MockSettings (in particular, RETURNS_DEEP_STUBS) using this syntax? It seems like you can either use this or this but not both.

Thanks!

Great! I’ll do some field tests tomorrow and draft a release in the coming week probably.

The MockSettings object is essentially a Builder. With that in mind, we can create the following function to replace the current withSettings():

fun withSettings(
      extraInterfaces: Array<KClass<Any>>? = null,
      name: String? = null,
      spiedInstance: Any? = null,
      defaultAnswer: Answer<Any>? = null,
      serializable: Boolean = false,
      serializableMode: SerializableMode? = null,
      verboseLogging: Boolean = false,
      invocationListeners: Array<InvocationListener>? = null,
      stubOnly: Boolean = false,
      @Incubating useConstructor: Boolean = false,
      @Incubating outerInstance: Any? = null
): MockSettings

This will not break current code as they will all use the default values. Using this, we can do the following:

-inline fun <reified T : Any> mock(): T
+inline fun <reified T : Any> mock(
+      extraInterfaces: Array<KClass<Any>>? = null,
+      name: String? = null,
+      spiedInstance: Any? = null,
+      defaultAnswer: Answer<Any>? = null,
+      serializable: Boolean = false,
+      serializableMode: SerializableMode? = null,
+      verboseLogging: Boolean = false,
+      invocationListeners: Array<InvocationListener>? = null,
+      stubOnly: Boolean = false,
+      @Incubating useConstructor: Boolean = false,
+      @Incubating outerInstance: Any? = null
+): T 

Usage would be intuitive:

val myMock = mock<MyClass>(
  name = "Custom name",
  verboseLogging = true
)

The same can be done for the stubbing variant:

val myMock = mock<MyClass>(
  name = "Custom name",
  verboseLogging = true
) {
  on { doSomething() } doReturn true
}

If this is introduced, we can deprecate the other mock functions (mock(Answer), mock(MockSettings) and mock(String)).

What do you think?
