The <application>cURL</application> package contains an utility
and a library used for transferring files with URL syntax to any of
the following protocols: DICT, FILE, FTP, FTPS, GOPHER, GOPHERS, HTTP,
HTTPS, IMAP, IMAPS, LDAP, LDAPS, MQTT, POP3, POP3S, RTSP, SMB, SMBS,
SMTP, SMPTS, TELNET, and TFTP. Its ability to both download
and upload files can be incorporated into other programs to support
functions like streaming media.

For version 7.54.1 I got:
TESTDONE: 869 tests out of 869 reported OK: 100%
TESTDONE: 1092 tests were considered during 1080 seconds

Running the test suite is optional. About 2% of the tests fail. Increase
in test time by each failed test is about 10%. Tests SBU above was
obtained disabling failing tests, with:
</para>
2017-10-29 - bdubbs
For version 7.56.1 I had a lot of test failures which included long
timeouts. Could not determine the cause of the timeouts or failures,
but I was missing c-ares, MIT Kerberos, ldap, samba, and the six
external packages.
2017-12-01 - bdubbs
Still a lot of test failures. I did have c-ares, Kerberos, and ldap
installed this time. Best guess is that servers are not available.
2018-08-01 - renodr
No test failures, but I didn't have any of the optional dependencies except
for c-ares and libidn2. I might re-run this test suite before release with
all of the optional deps, but right now, it isn't a priority - rather
the security fix is.
-->
<para>
To run the test suite, issue: <command>make test</command>.
One test, <filename>1477</filename>, is known to fail due to
a missing file in the curl tarball. Some tests are flaky,
so if some tests have failed it's possible to
run a test again with: <command>(cd tests; ./runtests.pl
<replaceable>&lt;test ID&gt;</replaceable>)</command> (the ID of
failed tests are shown in the <quote><computeroutput>These test cases
failed:</computeroutput></quote> message).
</para>
<!-- Two (of 857) tests
fail for unknown reasons, and all tests fail is valgrind is installed. Moving
valgrind out of $PATH is recommended if you wish to run the test suite while
it is installed.

if stunnel and valgrind are not installed, and also most options

and no. I don't have smb - so commenting the rest of this:
To run the test suite, issue: <command>make test</command>. Many tests
may fail that depend on optional dependencies that may not be installed
or upstream servers that may not be available, especially for tests
numbered 700 and above.
Test time may be significantly increase due to hanging tests that fail.

Added by Douglas for curl-7.61.0:
TESTDONE: 961 tests out of 961 reported OK: 100%
TESTDONE: 1202 tests were considered during 338 seconds.
I only have c-ares and libidn2 installed, I will likely try before release
with all optional dependencies in the book installed.
=========
7.61.1 NOTE: The test suite is extremely noisy, complaining about verification errors.
It's possible this is due to openssl-1.1.1, BUT 79/79 tests report as 100% OK. I had
c-ares, libpsl, and libidn1/2 installed. - Doug
========
7.62.0: All tests passed. libpsl, c-ares, libssh2, libidn2 installed.
All 1098 tests report OK.

For dependencies, I had c-ares, gnutls, libidn2, libpsl, krb5, libssh2, nghttp2,
OpenLDAP, Samba, stunnel, and Valgrind installed.

The tests that fail seem to be somewhat random. What happened between
yesterday and today that that tests 1139 1140 1173 now fail?

All BLFS dependencies are installed, and the tests were run with Valgrind
installed as well. Test 3021 and 3022 fails due to incompatibilities with
our version of SSH. See https://github.com/curl/curl/issues/12096
