Remove the .t wrappers Rename all of the TAP test applications from test-<test> to <test>_test to match the convention described in the TestSuite wiki page humanize_number_test.c: - Fix -Wformat warnings with counter variables - Fix minor style(9) issues: -- Header sorting -- Variable declaration alignment/sorting in main(..) -- Fit the lines in <80 columns - Fix an off by one index error in the testcase output [*] - Remove unnecessary `extern char * optarg;` (this is already provided by unistd.h) Phabric: D555 Approved by: jmmv (mentor) MFC after: 2 weeks Obtained from: EMC / Isilon Storage Division [*] Submitted by: Casey Peel <cpeel@isilon.com> [*] Sponsored by: EMC / Isilon Storage Division
