ZIO Test: Testing for error path

Question
1

Given following ZIO signature:

def validate(entity: Entity): IO[E, Entity] = ???

testing the success-path could look like that:

suite("testSuite") (
  test("test validate") (
    val expected = Entity(name = "Name")
    for
      actual <- validate(Entity(name = "Name"))
    yield assertTrue(actual == expected)
  )
)

But how would I test the error-path? The only thing I could think of is

suite("testSuite") (
  test("test validate") (
    val expected = E.NameIsBlank
    for
      actual <- validate(Entity(name = "Name")).flip
    yield assertTrue(actual == expected)
  )
)

Is this the expected way to do it or is there something I don’t see?

UPDATE: In the documentation I found this pattern, but I am not sure if this is the right approach in my case either:

suite("testSuite") (
  test("test validate") (
    val expectedError = E.NameIsBlank
    for
      exit <- validate(Entity(name = "Name")).exit
    yield assertTrue(exit == Exit.fail(expectedError))
  )
)
