Support private classes
A small library that provides helper functions to work with Mockito in Kotlin.
Mockito-Kotlin is available on JCenter. For Gradle users, add the following to your build.gradle
:
repositories { jcenter() } dependencies { testCompile "com.nhaarman:mockito-kotlin:x.x.x" }
Due to Kotlin‘s reified type parameters, if the type can be inferred, you don’t have to specify it explicitly:
Java:
MyClass c = mock(Myclass.class); c.doSomething(mock(MyOtherClass.class));
Kotlin:
val c : MyClass = mock() c.doSomething(mock())
If the type can't be inferred, you can pass it like so:
val d = mock<MyClass>()
Mockito‘s any(Class<T>)
often returns null
for non-primitive classes. In Kotlin, this can be a problem due to its null-safety feature. This library creates non-null instances when necessary. Again, if the type can be inferred, you don’t have to specify it explicitely:
Java:
verify(myClass).doSomething(any(String.class));
Kotlin:
verify(myClass).doSomething(any()); // Non-nullable parameter type is inferred
For generic arrays, use the anyArray()
method:
verify(myClass).setItems(anyArray())
Using higher-order functions, you can write very clear expectations about expected values. For example:
Kotlin:
verify(myClass).setItems(argThat{ size == 2 })
Most of Mockito‘s static functions are available as top-level functions. That means, IDE’s like IntelliJ can easily import and autocomplete them, saving you the hassle of manually importing them.
