| Documentation:
| The regex pattern to use for creating a buffer index.
|
| If non-nil this pattern is passed to `imenu--generic-function'
| to create a buffer index.
|
| The value should be an alist with elements that look like this:
|  (MENU-TITLE REGEXP INDEX)
| or like this:
|  (MENU-TITLE REGEXP INDEX FUNCTION ARGUMENTS...)
| with zero or more ARGUMENTS.  The former format creates a simple 
element in
| the index alist when it matches; the latter creates a special element
| of the form  (NAME POSITION-MARKER FUNCTION ARGUMENTS...)
| with FUNCTION and ARGUMENTS copied from `imenu-generic-expression'.
|
| MENU-TITLE is a string used as the title for the submenu or nil if the
| entries are not nested.
|
| REGEXP is a regexp that should match a construct in the buffer that is
| to be displayed in the menu; i.e., function or variable definitions,
| etc.  It contains a substring which is the name to appear in the
| menu.  See the info section on Regexps for more information.
|
| INDEX points to the substring in REGEXP that contains the name (of the
| function, variable or type) that is to appear in the menu.
|
| The variable is buffer-local.
|
| The variable `imenu-case-fold-search' determines whether or not the
| regexp matches are case sensitive, and `imenu-syntax-alist' can be
| used to alter the syntax table for the search.
|
| For example, see the value of `lisp-imenu-generic-expression' used by
| `fortran-mode' with `imenu-syntax-alist' set locally to give the
| characters which normally have "symbol" syntax "word" syntax
| during matching.
|
| Defined in `imenu'.

You've got an extra level of parentheses:

(setq tcl-imenu-generic-expression
      '(TestCases "^aetest::testcase -tc_id \\([_-A-Za-z0-9+]+\\)[
]+{" 1))

Also, [\n]+ would be more readable than a literal newline.
