Given foo (Some file with lines to count):

Execute(FixLocList should set all the default values correctly):
  AssertEqual
  \ [

  \     'lnum': 2,
  \     'col': 0,

  \   bufnr('%'),
  \   'foobar',
  \   [{'text': 'a', 'lnum': 2}, {'text': 'b', 'lnum': 2}],

Execute(FixLocList should use the values we supply):
  AssertEqual

  \     'col': 4,
  \     'bufnr': 10000,

  \     'type': 'W',
  \     'nr': 42,
  \   }],
  \ )

Execute(FixLocList should set items with lines beyond the end to the last line):
  AssertEqual
  \ [

  \     'lnum': 10,
  \     'col': 0,

  \ ale#engine#FixLocList(
  \   bufnr('%'),
  \   'foobar',
  \   [{'text': 'a', 'lnum': 11}],
  \ )

Execute(FixLocList should move line 0 to line 1):
  AssertEqual
  \ [

  \     'lnum': 1,
  \     'col': 0,

  \ ale#engine#FixLocList(
  \   bufnr('%'),
  \   'foobar',
  \   [{'text': 'a', 'lnum': 0}],

Execute(FixLocList should convert line and column numbers correctly):
  " The numbers should be 10, not 8 as octals.
  AssertEqual

  \   bufnr('%'),
  \   'foobar',
  \   [{'text': 'a', 'lnum': '010', 'col': '010'}],

Execute(FixLocList should pass on end_col values):
  " The numbers should be 10, not 8 as octals.
  AssertEqual

Execute(FixLocList should pass on end_lnum values):

Execute(FixLocList should allow subtypes to be set):
  AssertEqual
