How would you write assertThat(foo, instanceOf(Bar.class)) with Kotlin?
Seems that it does not like the .class
如果可能的话，我想要一个比assertTrue(foo is Bar)更"精确"的断言.

Bar::class返回KClass的实例，这是相当于Java Class的Kotlin.
instanceOf方法需要Class个实例，而不是KClass个，所以您必须使用Bar::class.java来转换它.
所以你的断言应该是这样的:
assertThat(foo, instanceOf(Bar::class.java))
More info about Java interop you can find here.
Also you can have a look at Hamkrest library which may add more fluency to your assertions:
assert.that(foo, isA<Bar>())
