comparison tests/automated/base64-tests.el @ 4855:189fb67ca31a

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Create Assert-eq, Assert-equal, etc. These are equivalent to (Assert (eq ...)) but display both the actual value and the expected value of the comparison. Use them throughout the test suite.
