Undo Assert-equal, Assert=, etc.; make `Assert' handle this automatically -------------------- ChangeLog entries follow: -------------------- lisp/ChangeLog addition: 2010-03-12 Ben Wing <ben@xemacs.org> * test-harness.el (test-harness-from-buffer): Undo change of e.g. (Assert (equalp ...)) to (Assert-equalp ...). Get rid of `Assert-equalp' and friends, `Assert-test', and `Assert-test-not'. Instead, make `Assert' smart enough to do the equivalent functionality when an expression like (Assert (equalp ...)) is seen. tests/ChangeLog addition: 2010-03-12 Ben Wing <ben@xemacs.org> * automated/base64-tests.el (bt-base64-encode-string): * automated/base64-tests.el (bt-base64-decode-string): * automated/base64-tests.el (for): * automated/byte-compiler-tests.el: * automated/byte-compiler-tests.el (before-and-after-compile-equal): * automated/case-tests.el (downcase-string): * automated/case-tests.el (uni-mappings): * automated/ccl-tests.el (ccl-test-normal-expr): * automated/ccl-tests.el (ccl-test-map-instructions): * automated/ccl-tests.el (ccl-test-suites): * automated/database-tests.el (delete-database-files): * automated/extent-tests.el (let): * automated/extent-tests.el (insert): * automated/extent-tests.el (props): * automated/file-tests.el: * automated/file-tests.el (for): * automated/hash-table-tests.el (test): * automated/hash-table-tests.el (for): * automated/hash-table-tests.el (ht): * automated/hash-table-tests.el (iterations): * automated/hash-table-tests.el (h1): * automated/hash-table-tests.el (equal): * automated/hash-table-tests.el (=): * automated/lisp-tests.el: * automated/lisp-tests.el (eq): * automated/lisp-tests.el (test-setq): * automated/lisp-tests.el (my-vector): * automated/lisp-tests.el (x): * automated/lisp-tests.el (equal): * automated/lisp-tests.el (y): * automated/lisp-tests.el (featurep): * automated/lisp-tests.el (=): * automated/lisp-tests.el (six): * automated/lisp-tests.el (three): * automated/lisp-tests.el (one): * automated/lisp-tests.el (two): * automated/lisp-tests.el (five): * automated/lisp-tests.el (test1): * automated/lisp-tests.el (division-test): * automated/lisp-tests.el (for): * automated/lisp-tests.el (check-function-argcounts): * automated/lisp-tests.el (z): * automated/lisp-tests.el (eql): * automated/lisp-tests.el (test-harness-risk-infloops): * automated/lisp-tests.el (erase-buffer): * automated/lisp-tests.el (sym): * automated/lisp-tests.el (new-char): * automated/lisp-tests.el (new-load-file-name): * automated/lisp-tests.el (cl-floor): * automated/lisp-tests.el (foo): * automated/md5-tests.el (lambda): * automated/md5-tests.el (large-string): * automated/md5-tests.el (mapcar): * automated/md5-tests.el (insert): * automated/mule-tests.el: * automated/mule-tests.el (test-chars): * automated/mule-tests.el (existing-file-name): * automated/mule-tests.el (featurep): * automated/query-coding-tests.el (featurep): * automated/regexp-tests.el: * automated/regexp-tests.el (insert): * automated/regexp-tests.el (Assert): * automated/regexp-tests.el (=): * automated/regexp-tests.el (featurep): * automated/regexp-tests.el (text): * automated/regexp-tests.el (text1): * automated/regexp-tests.el ("aáa"): * automated/regexp-tests.el (eql): * automated/search-tests.el (insert): * automated/search-tests.el (featurep): * automated/search-tests.el (let): * automated/search-tests.el (boundp): * automated/symbol-tests.el: * automated/symbol-tests.el (name): * automated/symbol-tests.el (check-weak-list-unique): * automated/symbol-tests.el (string): * automated/symbol-tests.el (list): * automated/symbol-tests.el (foo): * automated/symbol-tests.el (eq): * automated/symbol-tests.el (fresh-keyword-name): * automated/symbol-tests.el (print-gensym): * automated/symbol-tests.el (mysym): * automated/syntax-tests.el (test-forward-word): * automated/syntax-tests.el (test-backward-word): * automated/syntax-tests.el (test-syntax-table): * automated/syntax-tests.el (with-syntax-table): * automated/syntax-tests.el (Skip-Test-Unless): * automated/syntax-tests.el (with): * automated/tag-tests.el (testfile): * automated/weak-tests.el (w): * automated/weak-tests.el (p): * automated/weak-tests.el (a): Undo change of e.g. (Assert (equalp ...)) to (Assert-equalp ...).
