I've noticed this serious issue during writing a test case for my ticket
#1613. It is a problem with insertAsLastChildOf method. I used this method
to prepare a tree in first test case for that ticket (now it uses yaml
import). insertAsLastChildOf does not put nodes in right and correct
places. It puts them as first childs, it also corrupts next-level child
nodes including wrong parents and levels...
Now I've created a new test case. It has 5 test methods:
* testImportTree
* testInsertBySequence
* testInsertByLevel
* testInsertBySequenceReversed
* testInsertByLevelReversed
Every method generates tree using different styles. Methods should produce
the same tree:
{{{
id. (parent) name : LEFTxRIGHT
1. (0) Root : 1x20
2. (1) Node 1 : 2x3
3. (1) Node 2 : 4x15
4. (3) Node 21 : 5x6
5. (3) Node 22 : 7x8
6. (3) Node 23 : 9x12
7. (6) Node 231 : 10x11
8. (3) Node 24 : 13x14
9. (1) Node 3 : 16x17
10. (1) Node 4 : 18x19
}}}
Every method tests generated tree using the same asserts (they test every
node on name, left, right, level and parent). Every method also tests
moveAsNextSiblingOf and moveAsFirstChildOf on two nodes and after those
moving operations there are also some asserts.
'''ImportTree''' tests yaml import - everything is OK here.
'''testInsertBySequence''' and '''testInsertByLevel''' use
'''insertAsLastChildOf''' to insert nodes in tree - they are broken.
BySequence means that nodes are inserted in order they should appear in
tree. ByLevel means that it inserts first all nodes on level 1, then all
nodes on level 2 and so on. Reversed means that methods use
insertAsFirstChildOf (instead of insertAsLastChildOf). Each of them should
produce the same tree. In fact, they don't do it. :P
By now results of test case are:
{{{
Tested: 312 test cases.
Successes: 274 passes.
Failures: 76 fails.
}}}
I hope I have not done any mistakes in my test case ;)
In fact, NestedSet isn't well testcased in Doctrine Test Framework. There
are only single/multi root and yaml importing tests (and some connected
with tickets).
