GNU xargs treats the arguments to -I, -E, and -e as values even when
they begin with a hyphen. Clap was parsing those strings as options
instead, so invocations like 'xargs -I -_' failed before xargs could
process input.
Allow hyphen-leading values for those options and add regression
coverage for replacement and EOF markers that start with '-'.
Replaces assert_cmd/predicates/pretty_assertions/serial_test with uutests and
ctor in dev-dependencies.
Closes https://github.com/uutils/findutils/issues/537.
- Port tests/find_cmd_tests.rs → tests/test_find.rs (uutests API)
- Port tests/xargs_tests.rs → tests/test_xargs.rs (uutests API)
- Centralize UUTESTS_BINARY_PATH init via #[ctor::ctor] in tests/common/mod.rs
Implementation notes:
- Use TestScenario::cmd(BINARY_PATH) rather than ucmd(): find/xargs are
dedicated binaries, not multi-call, so ucmd() would prepend the utility name
as a spurious first argument
- Set CWD to CARGO_MANIFEST_DIR in find's ucmd() so relative test_data/ paths
resolve correctly regardless of where cargo runs
- delete_on_dot_dir sets the child process CWD via UCommand::current_dir()
instead of mutating the process-wide CWD, removing the need for serial_test
and all #[serial(working_dir)] attributes
Also fixes find_samefile, find_fprinter, and find_fprintf, which were writing
temporary files directly into test_data/. They now use isolated temp
directories, eliminating a source of test pollution when running in parallel.
