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 transferred 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) 165 </servercmd> 166 </reply> 167 168 <client> 169 170 <server> 171 What server(s) this test case requires/uses: 172 173 file 174 ftp 175 ftp-ipv6 176 ftps 177 http 178 http-ipv6 179 http-proxy 180 http-unix 181 https 182 httptls+srp 183 httptls+srp-ipv6 184 http/2 185 imap 186 none 187 pop3 188 rtsp 189 rtsp-ipv6 190 scp 191 sftp 192 smtp 193 socks4 194 socks5 195 196 Give only one per line. This subsection is mandatory. 197 </server> 198 199 <features> 200 A list of features that MUST be present in the client/library for this test to 201 be able to run. If a required feature is not present then the test will be 202 SKIPPED. 203 204 Alternatively a feature can be prefixed with an exclamation mark to indicate a 205 feature is NOT required. If the feature is present then the test will be 206 SKIPPED. 207 208 Features testable here are: 209 210 axTLS 211 crypto 212 debug 213 getrlimit 214 GnuTLS 215 GSS-API 216 http2 217 idn 218 ipv6 219 Kerberos 220 large_file 221 libz 222 Metalink 223 NSS 224 NTLM 225 OpenSSL 226 PSL 227 socks 228 SPNEGO 229 SSL 230 SSLpinning 231 SSPI 232 TLS-SRP 233 TrackMemory 234 unittest 235 unix-sockets 236 WinSSL 237 238 as well as each protocol that curl supports. A protocol only needs to be 239 specified if it is different from the server (useful when the server 240 is 'none'). 241 </features> 242 243 <killserver> 244 Using the same syntax as in <server> but when mentioned here these servers 245 are explicitly KILLED when this test case is completed. Only use this if there 246 is no other alternatives. Using this of course requires subsequent tests to 247 restart servers. 248 </killserver> 249 250 <precheck> 251 A command line that if set gets run by the test script before the test. If an 252 output is displayed by the command or if the return code is non-zero, the test 253 will be skipped and the (single-line) output will be displayed as reason for 254 not running the test. Variables are substituted as in the <command> section. 255 </precheck> 256 257 <postcheck> 258 A command line that if set gets run by the test script after the test. If 259 the command exists with a non-zero status code, the test will be considered 260 to have failed. Variables are substituted as in the <command> section. 261 </postcheck> 262 263 <tool> 264 Name of tool to use instead of "curl". This tool must be built and exist 265 either in the libtest/ directory (if the tool starts with 'lib') or in the 266 unit/ directory (if the tool starts with 'unit'). 267 </tool> 268 269 <name> 270 test case description 271 </name> 272 273 <setenv> 274 variable1=contents1 275 variable2=contents2 276 277 Set the given environment variables to the specified value before the actual 278 command is run. They are cleared again after the command has been run. 279 Variables are first substituted as in the <command> section. 280 </setenv> 281 282 <command [option="no-output/no-include"] [timeout="secs"] [delay="secs"] 283 [type="perl"]> 284 command line to run, there's a bunch of %variables that get replaced 285 accordingly. 286 287 Note that the URL that gets passed to the server actually controls what data 288 that is returned. The last slash in the URL must be followed by a number. That 289 number (N) will be used by the test-server to load test case N and return the 290 data that is defined within the <reply><data></data></reply> section. 291 292 If there's no test number found above, the HTTP test server will use the 293 number following the last dot in the given hostname (made so that a CONNECT 294 can still pass on test number) so that "foo.bar.123" gets treated as test case 295 123. Alternatively, if an IPv6 address is provided to CONNECT, the last 296 hexadecimal group in the address will be used as the test number! For example 297 the address "[1234::ff]" would be treated as test case 255. 298 299 Set type="perl" to write the test case as a perl script. It implies that 300 there's no memory debugging and valgrind gets shut off for this test. 301 302 Set option="no-output" to prevent the test script to slap on the --output 303 argument that directs the output to a file. The --output is also not added if 304 the verify/stdout section is used. 305 306 Set option="no-include" to prevent the test script to slap on the --include 307 argument. 308 309 Set timeout="secs" to override default server logs advisor read lock timeout. 310 This timeout is used by the test harness, once that the command has completed 311 execution, to wait for the test server to write out server side log files and 312 remove the lock that advised not to read them. The "secs" parameter is the not 313 negative integer number of seconds for the timeout. This 'timeout' attribute 314 is documented for completeness sake, but is deep test harness stuff and only 315 needed for very singular and specific test cases. Avoid using it. 316 317 Set delay="secs" to introduce a time delay once that the command has completed 318 execution and before the <postcheck> section runs. The "secs" parameter is the 319 not negative integer number of seconds for the delay. This 'delay' attribute 320 is intended for very specific test cases, and normally not needed. 321 322 Available substitute variables include: 323 %CLIENT6IP - IPv6 address of the client running curl 324 %CLIENTIP - IPv4 address of the client running curl 325 %CURL - Path to the curl executable 326 %FTP2PORT - Port number of the FTP server 2 327 %FTP6PORT - IPv6 port number of the FTP server 328 %FTPPORT - Port number of the FTP server 329 %FTPSPORT - Port number of the FTPS server 330 %FTPTIME2 - Timeout in seconds that should be just sufficient to receive 331 a response from the test FTP server 332 %FTPTIME3 - Even longer than %FTPTIME2 333 %GOPHER6PORT - IPv6 port number of the Gopher server 334 %GOPHERPORT - Port number of the Gopher server 335 %HOST6IP - IPv6 address of the host running this test 336 %HOSTIP - IPv4 address of the host running this test 337 %HTTP6PORT - IPv6 port number of the HTTP server 338 %HTTPPIPEPORT - Port number of the HTTP pipelining server 339 %HTTPUNIXPATH - Path to the Unix socket of the HTTP server 340 %HTTPPORT - Port number of the HTTP server 341 %HTTPSPORT - Port number of the HTTPS server 342 %HTTPTLS6PORT - IPv6 port number of the HTTP TLS server 343 %HTTPTLSPORT - Port number of the HTTP TLS server 344 %IMAP6PORT - IPv6 port number of the IMAP server 345 %IMAPPORT - Port number of the IMAP server 346 %POP36PORT - IPv6 port number of the POP3 server 347 %POP3PORT - Port number of the POP3 server 348 %PROXYPORT - Port number of the HTTP proxy 349 %PWD - Current directory 350 %RTSP6PORT - IPv6 port number of the RTSP server 351 %RTSPPORT - Port number of the RTSP server 352 %SMTP6PORT - IPv6 port number of the SMTP server 353 %SMTPPORT - Port number of the SMTP server 354 %SOCKSPORT - Port number of the SOCKS4/5 server 355 %SRCDIR - Full path to the source dir 356 %SSHPORT - Port number of the SCP/SFTP server 357 %TFTP6PORT - IPv6 port number of the TFTP server 358 %TFTPPORT - Port number of the TFTP server 359 %USER - Login ID of the user running the test 360 </command> 361 362 <file name="log/filename"> 363 This creates the named file with this content before the test case is run, 364 which is useful if the test case needs a file to act on. 365 Variables are substituted on the contents of the file as in the <command> 366 section. 367 </file> 368 369 <stdin [nonewline="yes"]> 370 Pass this given data on stdin to the tool. 371 372 If 'nonewline' is set, we will cut off the trailing newline of this given data 373 before comparing with the one actually received by the client 374 </stdin> 375 376 </client> 377 378 <verify> 379 <errorcode> 380 numerical error code curl is supposed to return. Specify a list of accepted 381 error codes by separating multiple numbers with comma. See test 237 for an 382 example. 383 </errorcode> 384 <strip> 385 One regex per line that is removed from the protocol dumps before the 386 comparison is made. This is very useful to remove dependencies on dynamically 387 changing protocol data such as port numbers or user-agent strings. 388 </strip> 389 <strippart> 390 One perl op per line that operates on the protocol dump. This is pretty 391 advanced. Example: "s/^EPRT .*/EPRT stripped/" 392 </strippart> 393 394 <protocol [nonewline="yes"]> 395 396 the protocol dump curl should transmit, if 'nonewline' is set, we will cut off 397 the trailing newline of this given data before comparing with the one actually 398 sent by the client Variables are substituted as in the <command> section. The 399 <strip> and <strippart> rules are applied before comparisons are made. 400 401 </protocol> 402 403 <proxy [nonewline="yes"]> 404 405 The protocol dump curl should transmit to a HTTP proxy (when the http-proxy 406 server is used), if 'nonewline' is set, we will cut off the trailing newline 407 of this given data before comparing with the one actually sent by the client 408 Variables are substituted as in the <command> section. The <strip> and 409 <strippart> rules are applied before comparisons are made. 410 411 </proxy> 412 413 <stdout [mode="text"] [nonewline="yes"]> 414 This verifies that this data was passed to stdout. Variables are 415 substituted as in the <command> section. 416 417 Use the mode="text" attribute if the output is in text mode on platforms that 418 have a text/binary difference. 419 420 If 'nonewline' is set, we will cut off the trailing newline of this given data 421 before comparing with the one actually received by the client 422 </stdout> 423 <file name="log/filename" [mode="text"]> 424 The file's contents must be identical to this after the test is complete. 425 Use the mode="text" attribute if the output is in text mode on platforms that 426 have a text/binary difference. 427 Variables are substituted as in the <command> section. 428 </file> 429 <stripfile> 430 One perl op per line that operates on the output file or stdout before being 431 compared with what is stored in the test file.
