== Running test suite: Set
-- Running test case: Set.prototype.find
PASS: Set can find a item it holds.
PASS: Set finds the first item if the given predicate matches multiple items.
PASS: Set returns 'undefined' when attempting to find an item if the given predicate doesn't match anything.

-- Running test case: Set.prototype.pushAll
Array:
[1,2] => [1,2,"a1","a2"]

Set:
[1,2] => [1,2,"s1","s2"]
[1,2] => [1,2,["s1","s1"],["s2","s2"]]
[1,2] => [1,2,"s1","s2"]
[1,2] => [1,2,"s1","s2"]

Map:
[1,2] => [1,2,["m1k","m1v"],["m2k","m2v"]]
[1,2] => [1,2,["m1k","m1v"],["m2k","m2v"]]
[1,2] => [1,2,"m1k","m2k"]
[1,2] => [1,2,"m1v","m2v"]

Object:
[1,2] => [1,2,["o1k","o1v"],["o2k","o2v"]]
[1,2] => [1,2,"o1k","o2k"]
[1,2] => [1,2,"o1v","o2v"]

Generator:
[1,2] => [1,2,"g1","g2"]

Node:
[1,2] => [1,2,<n1>,<n2>]
[1,2] => [1,2,<n1>,<n2>]

Object (doesn't have [Symbol.iterator]):
PASS: Should produce an exception.
TypeError: undefined is not a function (near '...item of iterable...')

-- Running test case: Set.prototype.take
PASS: Set can take `key`.
PASS: Set no longer has `key`.
PASS: Set can NOT take `key`.
PASS: Set can NOT take `DNE`, as it does NOT exist.

-- Running test case: Set.prototype.intersects
PASS: an empty set should not intersect another empty set.
PASS: a non-empty set should not intersect an empty set.
PASS: a set should intersect another set with the same values.
PASS: a set should not intersect another set with different values.
PASS: a set should intersect another set with same and additional values.
PASS: a set should intersect another set with same and different values.

-- Running test case: Set.prototype.isSubsetOf
PASS: an empty set should be a subset of another empty set.
PASS: an empty set should be a subset of a non-empty set.
PASS: a set should be a subset of another set with the same values.
PASS: a set should not be a subset of another set with different values.
PASS: a set should be a subset of another set with same and additional values.
PASS: a set should not be a subset of another set with same and different values.

-- Running test case: Set.prototype.equals
PASS: an empty set should be equal to another empty set.
PASS: a set should be equal to another set with the same values.
PASS: a set should be equal to another set with the same values in a different order.
PASS: a set should not be a equal to another set with different values.
PASS: a set should not be equal to another set with same and different values.

-- Running test case: Set.prototype.difference
Given a Set with values [], and another Set with values []:
PASS: Set difference should be [].

Given a Set with values [1,2,3], and another Set with values []:
PASS: Set difference should be [1,2,3].

Given a Set with values [], and another Set with values [1,2,3]:
PASS: Set difference should be [].

Given a Set with values [1,2,3], and another Set with values [2,3,4]:
PASS: Set difference should be [1].


-- Running test case: Set.prototype.firstValue
PASS: Set with values [] should have firstValue equal to undefined.
PASS: Set with values [1,2,3] should have firstValue equal to 1.

-- Running test case: Set.prototype.lastValue
PASS: Set with values [] should have lastValue equal to undefined.
PASS: Set with values [1,2,3] should have lastValue equal to 3.
