NAME ^

t/op/sprintf.t -- sprintf tests

SYNOPSIS ^

    % prove t/op/sprintf.t

DESCRIPTION ^

These tests are based on sprintf tests from perl 5.9.4.

Tests sprintf, excluding handling of 64-bit integers or long doubles (if supported), of machine-specific short and long integers, machine-specific floating point exceptions (infinity, not-a-number, etc.), of the effects of locale, and of features specific to multi-byte characters (under the utf8 pragma and such).

Individual tests are stored in the sprintf_tests file in the same directory; There is one test per line. In each test, there are three required fields:

Optional fields contain a comment.

Each field is separated by one or more tabs. If formatting requires more than one data item (for example, if variable field widths are used), the Parrot data expression should return a reference to an array having the requisite number of elements. Even so, subterfuge is sometimes required: see tests for %n and %p.

XXX: FIXME: TODO: ^

Tests that are expected to fail on a certain OS can be marked as such by trailing the comment with a skip: section. Skips are tags separated by space consisting of a $^O optionally trailed with :osvers. In the latter case, all os-levels below that are expected to fail. A special tag all is allowed for todo tests that should fail on any system.
