Looks like in PHP test 14 does not treat like 1.

Import: 10,7,12,11,13,4,14
Sorted: 1,4,7,10,11,12,13
test: 1,4,7,10,11
test: 4,7,10,11,12
test: 7,10,11,12,13
Return false

10, 7, 12 ,11, 13, 4, 14
Failed asserting that true matches expected false.

Should I return true here?
UPD: 14 counted as 14 and as 1 simultaneously.

Poker hands consist of 5 cards, as mentioned in the description:
"makes up a straight (five cards of sequential rank"

the 5 card straight (7-8-9-10-11) exists in those 7 cards.

All my tests are passing except test9IsStraight(PokerHandTest). I got a "Runtime Error Occurred".
What's the condition to that test??

How come the example 2-7-8-5-10-9-11 is straight??
shouldn't it be isNotStraight?

You're right, was an error in the test. Should be fixed now :)

Description is not clear in part of "The number of cards will vary, but will never be more than 7 (the board (5) + player hand (2))".
This Kata is not for level 7kuy definitely. Probably for 6kuy.

Java version :

The description says : "The number of cards will vary, but will never be more than 7 (the board (5) + player hand (2))"

And yet, some test case inputs contains 14, 21, 28 elements.... Please fix either description or test cases :)

Added random input
