Forward function to a ScalaTest macro

I am converting some QUnit Javascript tests to Scala. The tests I have look like this:

class XXX extends MyTests {
  test("equals", () => {
    val a = new XXX(x)
    val b = new XXX(y)
    ok(a.x != b.x, "Passed!")
    ok(a.y != b.y, "Passed!")
    ok(!a.equals(b), "Passed!")
    ok(!b.equals(a), "Passed!")
    a.copy(b)
    ok(a.x == b.x, "Passed!")
    ok(a.y == b.y, "Passed!")
    ok(a.equals(b), "Passed!")
    ok(b.equals(a), "Passed!")
  })
}

MyTests is my trait derived from ScalaTest FunSuite

I could replace ok with assert in the code, or I can place following in MyTests:

def ok(ok: Boolean, message: String) = assert(ok, message)

First solution results in better tests, as using assert directly means ScalaTest enhanced macro implementation of assert is used. Second solution is much less work, as I do not have to replace ok in the code.

Is there some way how to import assert under a different name from FunSuite or otherwise forward my implementation to the ScalaTest macro, so that ok behaves exactly as assert?
