Best approach when writing unit tests and using for-loops?

So I have a dilema with what is the best approach in this scenario. I am writing a Unit Test which looks something like this:

void testCorrectAxeParse() 
{
  // Arrange
  InputData in = m_inputData;
  Parser p = m_Parser;
  in.setAxe(idata::Axes::AX_LEFT);

  // Act
  OutData out = p.parse(in);

  // Assert
  AssertEquals(in.getAxe(), out.getAxe());
}

Now I have 4 values in the idata::Axes array.

Is it ok to write a for each statement in order to test every value or should I write 4 tests, one for each value in the enum?

I have read online that UT should be as small as possible, and I don't know if adding for loops is ok.

What test framework are you using? – Mureinik Sep 03 '20 at 07:36

common sense is more important than conventions. Can the individual array elements "fail" ? And more importantly, if an individual element fails, does this convey any useful information, does it matter which element was wrong? – 463035818_is_not_an_ai Sep 03 '20 at 08:00
