Simple test
-----------

hg topic -l list all changeset in the topic

  $ hg topic
   * foo
  $ hg topic --list
  0: c_c
  1: c_d
  2: c_e
  3: c_f

error case, nothing to list

  $ hg topic --clear
  $ hg topic --list
  abort: no active topic to list
  [255]

Test "t#" reference
-------------------


  $ hg up t1
  abort: cannot resolve "t1": no active topic
  [255]
  $ hg topic foo
  $ hg up t42
  abort: cannot resolve "t42": topic "foo" has only 4 changesets
  [255]
  $ hg up t1
  0 files updated, 0 files merged, 2 files removed, 0 files unresolved

Case with some of the topic unstable
------------------------------------

  $ echo bbb > ddd
  $ hg commit --amend
  $ hg log -G
