      1  The test suite's file format is very simple and extensible, closely
      2 resembling XML. All data for a single test case resides in a single
      3 ASCII file. Labels mark the beginning and the end of all sections, and each
      4 label must be written in its own line.  Comments are either XML-style
      5 (enclosed with <!-- and -->) or C-style (beginning with #) and must appear
      6 on their own lines and not alongside actual test data.  Most test data files
      7 are syntactically valid XML, although a few files are not (lack of
      8 support for character entities and the preservation of CR/LF characters at
      9 the end of lines are the biggest differences).
     10 
     11  The file begins with a 'testcase' tag, which encompasses the remainder of
     12 the file.
     13 
     14 <testcase>
     15 
     16  Each file is split up in three main sections: reply, client and verify. The
     17 reply section is used for the server to know what to send as a reply for the
     18 requests curl sends, the client section defines how the client should behave
     19 while the verify section defines how to verify that the data stored after a
     20 command has been run ended up correctly.
     21 
     22  Each main section has a number of available subsections that can be
     23 specified, that will be checked/used if specified. This document includes all
     24 the subsections currently supported.
     25 
     26 Main sections are 'info', 'reply', 'client' and 'verify'.
     27 
     28 <info>
     29 <keywords>
     30 A newline-separated list of keywords describing what this test case uses and
     31 tests. Try to use an already used keyword.  These keywords will be used for
     32 statistical/informational purposes and for choosing or skipping classes
     33 of tests.  "Keywords" must begin with an alphabetic character, "-", "["
     34 or "{" and may actually consist of multiple words separated by spaces
     35 which are treated together as a single identifier.
     36 </keywords>
     37 </info>
     38 
     39 <reply>
     40 <data [nocheck="yes"] [sendzero="yes"] [base64="yes"]>
     41 data to be sent to the client on its request and later verified that it arrived
     42 safely. Set nocheck="yes" to prevent the test script from verifying the arrival
     43 of this data.
     44 
     45 If the data contains 'swsclose' anywhere within the start and end tag, and
     46 this is a HTTP test, then the connection will be closed by the server after
     47 this response is sent. If not, the connection will be kept persistent.
     48 
     49 If the data contains 'swsbounce' anywhere within the start and end tag, the
     50 HTTP server will detect if this is a second request using the same test and
     51 part number and will then increase the part number with one. This is useful
     52 for auth tests and similar.
     53 
     54 'sendzero' set to yes means that the (FTP) server will "send" the data even if
     55 the size is zero bytes. Used to verify curl's behaviour on zero bytes
     56 transfers.
     57 
     58 'base64' set to yes means that the data provided in the test-file is a chunk
     59 of data encoded with base64. It is the only way a test case can contain binary
     60 data. (This attribute can in fact be used on any section, but it doesn't make
     61 much sense for other sections than "data").
     62 
     63 For FTP file listings, the <data> section will be used *only* if you make sure
     64 that there has been a CWD done first to a directory named 'test-[num]' where
     65 [num] is the test case number. Otherwise the ftp server can't know from which
     66 test file to load the list content.
     67 
     68 </data>
     69 <dataNUM>
     70 Send back this contents instead of the <data> one. The num is set by:
     71 A) The test number in the request line is >10000 and this is the remainder
     72 of [test case number]%10000.
     73 B) The request was HTTP and included digest details, which adds 1000 to NUM
     74 C) If a HTTP request is NTLM type-1, it adds 1001 to num
     75 D) If a HTTP request is NTLM type-3, it adds 1002 to num
     76 E) If a HTTP request is Basic and num is already >=1000, it adds 1 to num
     77 
     78 Dynamically changing num in this way allows the test harness to be used to
     79 test authentication negotiation where several different requests must be sent
     80 to complete a transfer. The response to each request is found in its own data
     81 section.  Validating the entire negotiation sequence can be done by
     82 specifying a datacheck section.
     83 </dataNUM>
     84 <connect>
     85 The connect section is used instead of the 'data' for all CONNECT
     86 requests. The remainder of the rules for the data section then apply but with
     87 a connect prefix.
     88 </connect>
     89 <datacheck [nonewline="yes"]>
     90 if the data is sent but this is what should be checked afterwards. If
     91 'nonewline' is set, we will cut off the trailing newline of this given data
     92 before comparing with the one actually received by the client
     93 </datacheck>
     94 <size>
     95 number to return on a ftp SIZE command (set to -1 to make this command fail)
     96 </size>
     97 <mdtm>
     98 what to send back if the client sends a (FTP) MDTM command, set to -1 to
     99 have it return that the file doesn't exist
    100 </mdtm>
    101 <postcmd>
    102 special purpose server-command to control its behavior *after* the
    103 reply is sent
    104 For HTTP/HTTPS, these are supported:
    105 
    106 wait [secs]
    107  - Pause for the given time
    108 </postcmd>
    109 <servercmd>
    110 Special-commands for the server.
    111 For FTP/SMTP/POP/IMAP, these are supported:
    112 
    113 REPLY [command] [return value] [response string]
    114  - Changes how the server responds to the [command]. [response string] is
    115    evaluated as a perl string, so it can contain embedded \r\n, for example.
    116    There's a special [command] named "welcome" (without quotes) which is the
    117    string sent immediately on connect as a welcome.
    118 COUNT [command] [num]
    119  - Do the REPLY change for [command] only [num] times and then go back to the
    120    built-in approach
    121 DELAY [command] [secs]
    122  - Delay responding to this command for the given time
    123 RETRWEIRDO
    124  - Enable the "weirdo" RETR case when multiple response lines appear at once
    125    when a file is transfered
    126 RETRNOSIZE
    127  - Make sure the RETR response doesn't contain the size of the file
    128 NOSAVE
    129  - Don't actually save what is received
    130 SLOWDOWN
    131  - Send FTP responses with 0.01 sec delay between each byte
    132 PASVBADIP
    133  - makes PASV send back an illegal IP in its 227 response
    134 CAPA [capabilities]
    135  - Enables support for and specifies a list of space separated capabilities to
    136    return to the client for the IMAP CAPABILITY, POP3 CAPA and SMTP EHLO
    137    commands
    138 AUTH [mechanisms]
    139  - Enables support for SASL authentication and specifies a list of space
    140    separated mechanisms for IMAP, POP3 and SMTP
    141 
    142 For HTTP/HTTPS:
    143 auth_required   if this is set and a POST/PUT is made without auth, the
    144                 server will NOT wait for the full request body to get sent
    145 idle            do nothing after receiving the request, just "sit idle"
    146 stream          continuously send data to the client, never-ending
    147 writedelay: [secs] delay this amount between reply packets
    148 pipe: [num]     tell the server to expect this many HTTP requests before
    149                 sending back anything, to allow pipelining tests
    150 skip: [num]     instructs the server to ignore reading this many bytes from a PUT
    151                 or POST request
    152 
    153 rtp: part [num] channel [num] size [num]
    154                stream a fake RTP packet for the given part on a chosen channel
    155                with the given payload size
    156 
    157 connection-monitor When used, this will log [DISCONNECT] to the server.input
    158                log when the connection is disconnected.
    159 upgrade        when an HTTP upgrade header is found, the server will upgrade
    160                to http2
    161 
    162 For TFTP:
    163 writedelay: [secs] delay this amount between reply packets (each packet being
    164                    512 bytes payload)

    200 be able to run. If a required feature is not present then the test will be
    201 SKIPPED.
    202 
    203 Alternatively a feature can be prefixed with an exclamation mark to indicate a
    204 feature is NOT required. If the feature is present then the test will be

    234 
    235 as well as each protocol that curl supports.  A protocol only needs to be
    236 specified if it is different from the server (useful when the server
    237 is 'none').
    238 </features>
    239 
    240 <killserver>
    241 Using the same syntax as in <server> but when mentioned here these servers
    242 are explicitly KILLED when this test case is completed. Only use this if there
    243 is no other alternatives. Using this of course requires subsequent tests to
    244 restart servers.
    245 </killserver>
    246 
    247 <precheck>
    248 A command line that if set gets run by the test script before the test. If an
    249 output is displayed by the command or if the return code is non-zero, the test
    250 will be skipped and the (single-line) output will be displayed as reason for
    251 not running the test.  Variables are substituted as in the <command> section.
    252 </precheck>
    253 
    254 <postcheck>
    255 A command line that if set gets run by the test script after the test. If
    256 the command exists with a non-zero status code, the test will be considered
    257 to have failed. Variables are substituted as in the <command> section.
    258 </postcheck>
    259 
    260 <tool>
    261 Name of tool to use instead of "curl". This tool must be built and exist
    262 either in the libtest/ directory (if the tool starts with 'lib') or in the
    263 unit/ directory (if the tool starts with 'unit').
    264 </tool>
    265 
    266 <name>
    267 test case description
    268 </name>
    269 
    270 <setenv>
    271 variable1=contents1
    272 variable2=contents2
    273 
    274 Set the given environment variables to the specified value before the actual
    275 command is run. They are cleared again after the command has been run.
    276 Variables are first substituted as in the <command> section.
    277 </setenv>
    278 
    279 <command [option="no-output/no-include"] [timeout="secs"] [delay="secs"]
    280          [type="perl"]>
    281 command line to run, there's a bunch of %variables that get replaced
    282 accordingly.
    283 
    284 Note that the URL that gets passed to the server actually controls what data
    285 that is returned. The last slash in the URL must be followed by a number. That
    286 number (N) will be used by the test-server to load test case N and return the
    287 data that is defined within the <reply><data></data></reply> section.
    288 
    289 If there's no test number found above, the HTTP test server will use the
    290 number following the last dot in the given hostname (made so that a CONNECT
    291 can still pass on test number) so that "foo.bar.123" gets treated as test case
    292 123. Alternatively, if an IPv6 address is provided to CONNECT, the last
    293 hexadecimal group in the address will be used as the test numer! For example
    294 the address "[1234::ff]" would be treated as test case 255.
    295 
    296 Set type="perl" to write the test case as a perl script. It implies that
    297 there's no memory debugging and valgrind gets shut off for this test.
    298 
    299 Set option="no-output" to prevent the test script to slap on the --output
    300 argument that directs the output to a file. The --output is also not added if
    301 the verify/stdout section is used.
    302 
    303 Set option="no-include" to prevent the test script to slap on the --include
    304 argument.
    305 
    306 Set timeout="secs" to override default server logs advisor read lock timeout.
    307 This timeout is used by the test harness, once that the command has completed
    308 execution, to wait for the test server to write out server side log files and
    309 remove the lock that advised not to read them. The "secs" parameter is the not
    310 negative integer number of seconds for the timeout. This 'timeout' attribute
    311 is documented for completeness sake, but is deep test harness stuff and only
    312 needed for very singular and specific test cases. Avoid using it.
    313 
    314 Set delay="secs" to introduce a time delay once that the command has completed
    315 execution and before the <postcheck> section runs. The "secs" parameter is the
    316 not negative integer number of seconds for the delay. This 'delay' attribute
    317 is intended for very specific test cases, and normally not needed.
    318 
    319 Available substitute variables include:
    320 %CLIENT6IP - IPv6 address of the client running curl
    321 %CLIENTIP  - IPv4 address of the client running curl
    322 %CURL      - Path to the curl executable

    357 </command>
    358 
    359 <file name="log/filename">
    360 This creates the named file with this content before the test case is run,
    361 which is useful if the test case needs a file to act on.
    362 Variables are substituted on the contents of the file as in the <command>
    363 section.
    364 </file>
    365 
    366 <stdin [nonewline="yes"]>
    367 Pass this given data on stdin to the tool.
    368 
    369 If 'nonewline' is set, we will cut off the trailing newline of this given data
    370 before comparing with the one actually received by the client

    373 </client>
    374 
    375 <verify>
    376 <errorcode>
    377 numerical error code curl is supposed to return. Specify a list of accepted
    378 error codes by separating multiple numbers with comma. See test 237 for an
    379 example.
    380 </errorcode>
    381 <strip>
    382 One regex per line that is removed from the protocol dumps before the
    383 comparison is made. This is very useful to remove dependencies on dynamically
    384 changing protocol data such as port numbers or user-agent strings.
    385 </strip>
    386 <strippart>
    387 One perl op per line that operates on the protocol dump. This is pretty
    388 advanced. Example: "s/^EPRT .*/EPRT stripped/"
    389 </strippart>
    390 
    391 <protocol [nonewline="yes"]>
    392 
    393 the protocol dump curl should transmit, if 'nonewline' is set, we will cut off
    394 the trailing newline of this given data before comparing with the one actually
    395 sent by the client Variables are substituted as in the <command> section.  The

    401 
    402 The protocol dump curl should transmit to a HTTP proxy (when the http-proxy
    403 server is used), if 'nonewline' is set, we will cut off the trailing newline
    404 of this given data before comparing with the one actually sent by the client

    410 <stdout [mode="text"] [nonewline="yes"]>
    411 This verifies that this data was passed to stdout.  Variables are
    412 substituted as in the <command> section.
    413 
    414 Use the mode="text" attribute if the output is in text mode on platforms that
    415 have a text/binary difference.
    416 
    417 If 'nonewline' is set, we will cut off the trailing newline of this given data
    418 before comparing with the one actually received by the client
