Consider this unit test for C#$\text{'}$s HashSet class:

$[$TestClass$()]$

public class HashSetTests

$\{$

private HashSet hs $=$ new $()$;

$[$TestMethod$]$

$[$ExpectedException$($ typeof$($ ArgumentException $))]$

public void Remove$\_$BecomesEmpty$\_$Succeeds$()$

$\{$

hs$.$Add$(1)$;

hs$.$Remove$(1)$;

$\}$

$\}$

You can consult the specification for C#$\text{'}$s HashSet class hereLinks to an external site., but it probably works the way you think it should.

Assume there are other tests in the test class that are not show here. Which of the following are design or correctness problems exhibited by this test? Select all that apply.

Group of answer choices

It is poorly named

It expects an exception when it should not

It calls more than one HashSet method

Its state is not self$-$contained
