Automated testing for other alignment constraints

[jbellik]

Create an html file with Mocha tests for:

Align left/right Focus
Align left/right lexical item

[jbellik]

Let stree = [a.foc [b.foc [c.foc]]], where all terminal nodes have foc:true
Then:
alignFocLeft(stree, {(a.foc (b.foc (c.foc)))}, phi) = 0
alignFocRight(stree, {(a.foc (b.foc (c.foc)))}, phi) = 2

alignFocLeft(stree, {(((a.foc) b.foc) c.foc)}, phi) = 2
alignFocRight(stree, {(((a.foc) b.foc) c.foc)}, phi) = 0

alignFocLeft(stree, {(a.foc b.foc c.foc)}, phi) = 2
alignFocRight(stree, {(a.foc b.foc c.foc)}, phi) = 2

alignFocLeft(stree, {a.foc b.foc c.foc}, phi) = 3
alignFocRight(stree, {a.foc b.foc c.foc}, phi) = 3

alignFocLeft(stree, {a.foc {b.foc {c.foc}}}, i) = 0
alignFocRight(stree, {{{a.foc} b.foc} c.foc}, i) = 0
alignFocLeft(stree, {a.foc {b.foc {c.foc}}}, phi) = 3
alignFocRight(stree, {{{a.foc} b.foc} c.foc}, phi) = 3
alignFocLeft(stree, {a.foc {b.foc {c.foc}}}, w) = 0
alignFocRight(stree, {{{a.foc} b.foc} c.foc}, w) = 0

The maximum number of violations is the number of focused terminals in the output.
alignFocLeft(stree, {a {b.foc {c}}}, i) = 0
alignFocRight(stree, {{{a} b.foc} c}, i) = 0
alignFocLeft(stree, {a {b.foc {c}}}, phi) = 1
alignFocRight(stree, {{{a} b.foc} c}, phi) = 1
alignFocLeft(stree, {a {b.foc {c.foc}}}, phi) = 2
alignFocRight(stree, {{{a} b.foc} c.foc}, phi) = 2

Expected results for alignLeftMorpheme(stree, ptree, 'x') (where x is supposed to be aligned all the way left):
ptree = {a b c x} --> 4
{a b x c} --> 3
{a x b c} --> 1
{a b c} --> 0

Also test that alignLeftMorpheme can handle a space separated string of morphemes to check for. Expected results for alignLeftMorpheme(stree, ptree, 'x y'):
ptree = {a b c x y} --> 3 violations for x and 4 violations for y = 7 violations
{x y a b c} --> 0 violations for x and 1 violation for y = 1 violation total
{x a b c y} --> 4 total (for y)

Mirror image results should obtain for alignRightMorpheme.
