How to handle default arguments

[jetjager]

Hi, I struggle with finding a method for mocking, when the method has default arguments.
The following fails with java.lang.AssertionError: Unexpected method call Foo.bar$default$2()

//> using dep "org.scalatest::scalatest:3.2.17"
//> using dep "org.scalatestplus::easymock-5-1:3.2.17.0"
//> using dep "org.easymock:easymock:5.1.0"
import org.scalatestplus.easymock.EasyMockSugar
import org.scalatest.funsuite.AnyFunSuite
import org.easymock.EasyMock.{capture, newCapture}

trait Foo {
  def bar(a: String, b: Int = 0): String
}

class EasyMockTest extends AnyFunSuite with EasyMockSugar {

  test("test") {
    val foo = mock[Foo]

    val aCapture = newCapture[String]
    val bCapture = newCapture[Int]
    expecting {
      foo.bar(capture(aCapture), capture(bCapture)).andStubReturn("bar")
    }

    whenExecuting(foo) {
      val bar1 = foo.bar("a", 0)
      assert(bar1 == "bar")

      val bar2 = foo.bar("a")
      assert(bar2 == "bar")

    }
  }
}
