用MockK捕获可变参数？

Question

您可以在MockK中mock一个vararg方法：

interface ClsWithManyMany {
    fun manyMany(vararg x: Any): Int
}

val obj = mockk<ClsWithManyMany>()
every { obj.manyMany(*anyVararg()) } returns 2
println(obj.manyMany("testing", "testing")) // 2

如何捕获传递给该方法的值？这不起作用(捕获mutableListOf<Array<Any>>()也不起作用)：

val captured = slot<Array<Any>>()
every { obj.manyMany(*capture(captured)) } answers {
    println ("arguments: ${captured.captured}")
    2
}

Answer 1

您可以执行以下操作：

val captured = mutableListOf<Any?>()
every { obj.manyMany(*varargAllNullable { captured.add(it) }) } answers {
    println ("arguments: $captured")
    captured.clear()
    2
}

This issue是开放的，允许以一种不那么繁琐的方式来实现这一点。
