Go Translation ;)

Haskell tests generate strings outside of ASCII range. Fork here fixes it, along with updating the tests so failure messages are more 7kyu-friendly and show the tested string without the QuickCheck modifier cruft.

No random tests in CoffeeScript

Sample tests of all languages should follow the Python setup by including test cases for

• Array of numbers

• Array of strings

• Empty String

• Empty Array

No random tests in TS

• Java: no random tests.
• JavaScripts: random tests are not random.

In c++ it keeps failing with exit code 132, eventhough the tests seem to pass and the log is empty.
I tried to google exit code 132, but found nothing that seemed applicable to this situation.
Does anybody know what might be going on here?

A best practice when templating this kind of algorithm is to
make it generic, i.e. pass a range or [begin,end) as template parameters...
Indeed, the initial parameter says 'iterable' :-)
May also test with any kind of ordered iterable, so that one may use concepts one day and return {} if the values cannot be ordered ?

There's a few missing C# test cases

[Test]
public void NullSequence()
{
  Assert.That(Kata.UniqueInOrder(null), Throws.InstanceOf<ArgumentNullException>());
  // OR (undefined requirement)
  Assert.That(Kata.UniqueInOrder(null), Is.Empty)
}

[Test]
public void NullValue()
{
  // Breaks solutions that use default as a placeholder value
  Assert.That(Kata.UniqueInOrder(new string[]{"Hello", null, null, "world"}), Is.EqualTo(new string[]{"Hello", null, "world"}));
}

[Test]
public void LeadingZero()
{
  // Breaks solutions that use default as a placeholder value
  Assert.That(Kata.UniqueInOrder(new int[]{0, 1, 2, 3}), Is.EqualTo(new int[]{0, 1, 2, 3}));
}

[Test]
public void EmptyIntegerArray()
{
  // Breaks solutions that use default as a placeholder value
  Assert.That(Kata.UniqueInOrder(Array.Empty<int>()), Is.EqualTo(Array.Empty<int>()));
}

[Test]
public void MixedTypes()
{
  // Make sure solutions don't use assumptions between types
  Assert.That(Kata.UniqueInOrder(new object[]{1, "2", 2, 2, "5", "5"}), Is.EqualTo(new object[]{1, "2", 2, "5"}));
}

private class Foo
{
  public override bool Equals(object other) => other is Foo || other is Bar;
}

private class Bar
{
  public override bool Equals(object other) => other is Foo || other is Bar;
}

[Test]
public void RemovesDuplicateCustomTypes()
{
  // Make sure solutions don't use assumptions between types
  Assert.That(Kata.UniqueInOrder(new object[]{new Foo(), 1, new Bar(), new Foo(), string.Empty}).Select(res => res.GetType()), Is.EqualTo(new object[]{typeof(Foo), typeof(1), typeof(Bar), typeof(string)}));
}

The sample tests in crystal expect an array of strings whereas the random tests expect an array of characters
