Scala中的参数化单元测试(使用JUnit4)

import org.junit.Assert._
import org.junit.Test
import org.junit.runner.RunWith
import org.junit.runners.Parameterized
import org.junit.runners.Parameterized.Parameters

@RunWith(classOf[Parameterized])
class ParameterizedTest(val input: Int, val expected: Int) {
  @Test
  def testMultiply(): Unit = {
    val result = multiply(input)
    assertEquals(expected, result)
  }
}

object ParameterizedTest {
  @Parameters
  def data(): java.util.Collection[Array[AnyRef]] = {
    val data = Array(
      Array(1, 2),
      Array(2, 4),
      Array(3, 6),
      Array(4, 8),
      Array(5, 10)
    )
    java.util.Arrays.asList(data: _*)
  }

  def multiply(input: Int): Int = {
    input * 2
  }
}
