The test suite's file format is very simple and extensible, closely resembling XML. All data for a single test case resides in a single ASCII file. Labels mark the beginning and the end of all sections, and each label must be written in its own line. Comments are either XML-style (enclosed with ) or C-style (beginning with #) and must appear on their own lines and not alongside actual test data. Most test data files are syntactically valid XML, although a few files are not (lack of support for character entities and the preservation of CR/LF characters at the end of lines are the biggest differences). The file begins with a 'testcase' tag, which encompasses the remainder of the file. Each file is split up in three main sections: reply, client and verify. The reply section is used for the server to know what to send as a reply for the requests curl sends, the client section defines how the client should behave while the verify section defines how to verify that the data stored after a command has been run ended up correctly. Each main section has a number of available subsections that can be specified, that will be checked/used if specified. This document includes all the subsections currently supported. Main sections are 'info', 'reply', 'client' and 'verify'. A newline-separated list of keywords describing what this test case uses and tests. Try to use an already used keyword. These keywords will be used for statistical/informational purposes and for choosing or skipping classes of tests. "Keywords" must begin with an alphabetic character, "-", "[" or "{" and may actually consist of multiple words separated by spaces which are treated together as a single identifier. data to be sent to the client on its request and later verified that it arrived safely. Set nocheck="yes" to prevent the test script from verifying the arrival of this data. If the data contains 'swsclose' anywhere within the start and end tag, and this is a HTTP test, then the connection will be closed by the server after this response is sent. If not, the connection will be kept persistent. If the data contains 'swsbounce' anywhere within the start and end tag, the HTTP server will detect if this is a second request using the same test and part number and will then increase the part number with one. This is useful for auth tests and similar. 'sendzero' set to yes means that the (FTP) server will "send" the data even if the size is zero bytes. Used to verify curl's behaviour on zero bytes transfers. 'base64' set to yes means that the data provided in the test-file is a chunk of data encoded with base64. It is the only way a test case can contain binary data. (This attribute can in fact be used on any section, but it doesn't make much sense for other sections than "data"). 'hex' set to yes means that the data is a sequence of hex pairs. It will get decoded and used as "raw" data. For FTP file listings, the section will be used *only* if you make sure that there has been a CWD done first to a directory named 'test-[num]' where [num] is the test case number. Otherwise the ftp server can't know from which test file to load the list content. Send back this contents instead of the one. The num is set by: A) The test number in the request line is >10000 and this is the remainder of [test case number]%10000. B) The request was HTTP and included digest details, which adds 1000 to NUM C) If a HTTP request is NTLM type-1, it adds 1001 to num D) If a HTTP request is NTLM type-3, it adds 1002 to num E) If a HTTP request is Basic and num is already >=1000, it adds 1 to num F) If a HTTP request is Negotiate, num gets incremented by one for each request with Negotiate authorization header on the same test case. Dynamically changing num in this way allows the test harness to be used to test authentication negotiation where several different requests must be sent to complete a transfer. The response to each request is found in its own data section. Validating the entire negotiation sequence can be done by specifying a datacheck section. The connect section is used instead of the 'data' for all CONNECT requests. The remainder of the rules for the data section then apply but with a connect prefix. if the data is sent but this is what should be checked afterwards. If 'nonewline' is set, we will cut off the trailing newline of this given data before comparing with the one actually received by the client. Use the mode="text" attribute if the output is in text mode on platforms that have a text/binary difference. The contents of numbered datacheck sections are appended to the non-numbered one. number to return on a ftp SIZE command (set to -1 to make this command fail) what to send back if the client sends a (FTP) MDTM command, set to -1 to have it return that the file doesn't exist special purpose server-command to control its behavior *after* the reply is sent For HTTP/HTTPS, these are supported: wait [secs] - Pause for the given time Special-commands for the server. For FTP/SMTP/POP/IMAP, these are supported: REPLY [command] [return value] [response string] - Changes how the server responds to the [command]. [response string] is evaluated as a perl string, so it can contain embedded \r\n, for example. There's a special [command] named "welcome" (without quotes) which is the string sent immediately on connect as a welcome. REPLYLF (like above but sends the response terminated with LF-only and not CRLF) COUNT [command] [num] - Do the REPLY change for [command] only [num] times and then go back to the built-in approach DELAY [command] [secs] - Delay responding to this command for the given time RETRWEIRDO - Enable the "weirdo" RETR case when multiple response lines appear at once when a file is transferred RETRNOSIZE - Make sure the RETR response doesn't contain the size of the file NOSAVE - Don't actually save what is received SLOWDOWN - Send FTP responses with 0.01 sec delay between each byte PASVBADIP - makes PASV send back an illegal IP in its 227 response CAPA [capabilities] - Enables support for and specifies a list of space separated capabilities to return to the client for the IMAP CAPABILITY, POP3 CAPA and SMTP EHLO commands AUTH [mechanisms] - Enables support for SASL authentication and specifies a list of space separated mechanisms for IMAP, POP3 and SMTP For HTTP/HTTPS: auth_required if this is set and a POST/PUT is made without auth, the server will NOT wait for the full request body to get sent idle do nothing after receiving the request, just "sit idle" stream continuously send data to the client, never-ending writedelay: [secs] delay this amount between reply packets skip: [num] instructs the server to ignore reading this many bytes from a PUT or POST request rtp: part [num] channel [num] size [num] stream a fake RTP packet for the given part on a chosen channel with the given payload size connection-monitor When used, this will log [DISCONNECT] to the server.input log when the connection is disconnected. upgrade when an HTTP upgrade header is found, the server will upgrade to http2 swsclose instruct server to close connection after response no-expect don't read the request body if Expect: is present For TFTP: writedelay: [secs] delay this amount between reply packets (each packet being 512 bytes payload) What server(s) this test case requires/uses: file ftp ftp-ipv6 ftps http http-ipv6 http-proxy http-unix https httptls+srp httptls+srp-ipv6 http/2 imap none pop3 rtsp rtsp-ipv6 scp sftp smtp socks4 socks5 Give only one per line. This subsection is mandatory. A list of features that MUST be present in the client/library for this test to be able to run. If a required feature is not present then the test will be SKIPPED. Alternatively a feature can be prefixed with an exclamation mark to indicate a feature is NOT required. If the feature is present then the test will be SKIPPED. Features testable here are: alt-svc crypto debug getrlimit GnuTLS GSS-API http/2 idn ipv6 Kerberos large_file ld_preload libz manual Metalink NSS NTLM OpenSSL PSL socks SPNEGO SSL SSLpinning SSPI threaded-resolver TLS-SRP TrackMemory unittest unix-sockets win32 WinSSL as well as each protocol that curl supports. A protocol only needs to be specified if it is different from the server (useful when the server is 'none'). Using the same syntax as in but when mentioned here these servers are explicitly KILLED when this test case is completed. Only use this if there is no other alternatives. Using this of course requires subsequent tests to restart servers. A command line that if set gets run by the test script before the test. If an output is displayed by the command or if the return code is non-zero, the test will be skipped and the (single-line) output will be displayed as reason for not running the test. Variables are substituted as in the section. A command line that if set gets run by the test script after the test. If the command exists with a non-zero status code, the test will be considered to have failed. Variables are substituted as in the section. Name of tool to use instead of "curl". This tool must be built and exist either in the libtest/ directory (if the tool starts with 'lib') or in the unit/ directory (if the tool starts with 'unit'). test case description variable1=contents1 variable2=contents2 Set the given environment variables to the specified value before the actual command is run. They are cleared again after the command has been run. Variables are first substituted as in the section. command line to run, there's a bunch of %variables that get replaced accordingly. Note that the URL that gets passed to the server actually controls what data that is returned. The last slash in the URL must be followed by a number. That number (N) will be used by the test-server to load test case N and return the data that is defined within the section. If there's no test number found above, the HTTP test server will use the number following the last dot in the given hostname (made so that a CONNECT can still pass on test number) so that "foo.bar.123" gets treated as test case 123. Alternatively, if an IPv6 address is provided to CONNECT, the last hexadecimal group in the address will be used as the test number! For example the address "[1234::ff]" would be treated as test case 255. Set type="perl" to write the test case as a perl script. It implies that there's no memory debugging and valgrind gets shut off for this test. Set option="no-output" to prevent the test script to slap on the --output argument that directs the output to a file. The --output is also not added if the verify/stdout section is used. Set option="force-output" to make use of --output even when the test is otherwise written to verify stdout. Set option="no-include" to prevent the test script to slap on the --include argument. Set option="binary-trace" to use --trace instead of --trace-ascii for tracing. Suitable for binary-oriented protocols such as MQTT. Set timeout="secs" to override default server logs advisor read lock timeout. This timeout is used by the test harness, once that the command has completed execution, to wait for the test server to write out server side log files and remove the lock that advised not to read them. The "secs" parameter is the not negative integer number of seconds for the timeout. This 'timeout' attribute is documented for completeness sake, but is deep test harness stuff and only needed for very singular and specific test cases. Avoid using it. Set delay="secs" to introduce a time delay once that the command has completed execution and before the section runs. The "secs" parameter is the not negative integer number of seconds for the delay. This 'delay' attribute is intended for very specific test cases, and normally not needed. Available substitute variables include: %CLIENT6IP - IPv6 address of the client running curl %CLIENTIP - IPv4 address of the client running curl %CURL - Path to the curl executable %FTP2PORT - Port number of the FTP server 2 %FTP6PORT - IPv6 port number of the FTP server %FTPPORT - Port number of the FTP server %FTPSPORT - Port number of the FTPS server %FTPTIME2 - Timeout in seconds that should be just sufficient to receive a response from the test FTP server %FTPTIME3 - Even longer than %FTPTIME2 %GOPHER6PORT - IPv6 port number of the Gopher server %GOPHERPORT - Port number of the Gopher server %HOST6IP - IPv6 address of the host running this test %HOSTIP - IPv4 address of the host running this test %HTTP6PORT - IPv6 port number of the HTTP server %HTTPUNIXPATH - Path to the Unix socket of the HTTP server %HTTPPORT - Port number of the HTTP server %HTTPSPORT - Port number of the HTTPS server %HTTPTLS6PORT - IPv6 port number of the HTTP TLS server %HTTPTLSPORT - Port number of the HTTP TLS server %IMAP6PORT - IPv6 port number of the IMAP server %IMAPPORT - Port number of the IMAP server %POP36PORT - IPv6 port number of the POP3 server %POP3PORT - Port number of the POP3 server %PROXYPORT - Port number of the HTTP proxy %PWD - Current directory %POSIX_PWD - Current directory somewhat mingw friendly %FILE_PWD - Current directory, on windows prefixed with a slash %RTSP6PORT - IPv6 port number of the RTSP server %RTSPPORT - Port number of the RTSP server %SSHSRVMD5 - MD5 of SSH server's public key %SMTP6PORT - IPv6 port number of the SMTP server %SMTPPORT - Port number of the SMTP server %SOCKSPORT - Port number of the SOCKS4/5 server %SRCDIR - Full path to the source dir %SSHPORT - Port number of the SCP/SFTP server %TFTP6PORT - IPv6 port number of the TFTP server %TFTPPORT - Port number of the TFTP server %USER - Login ID of the user running the test This creates the named file with this content before the test case is run, which is useful if the test case needs a file to act on. Variables are substituted on the contents of the file as in the section. Pass this given data on stdin to the tool. If 'nonewline' is set, we will cut off the trailing newline of this given data before comparing with the one actually received by the client numerical error code curl is supposed to return. Specify a list of accepted error codes by separating multiple numbers with comma. See test 237 for an example. One regex per line that is removed from the protocol dumps before the comparison is made. This is very useful to remove dependencies on dynamically changing protocol data such as port numbers or user-agent strings. One perl op per line that operates on the protocol dump. This is pretty advanced. Example: "s/^EPRT .*/EPRT stripped/" the protocol dump curl should transmit, if 'nonewline' is set, we will cut off the trailing newline of this given data before comparing with the one actually sent by the client Variables are substituted as in the section. The and rules are applied before comparisons are made. The protocol dump curl should transmit to a HTTP proxy (when the http-proxy server is used), if 'nonewline' is set, we will cut off the trailing newline of this given data before comparing with the one actually sent by the client Variables are substituted as in the section. The and rules are applied before comparisons are made. This verifies that this data was passed to stdout. Variables are substituted as in the section. Use the mode="text" attribute if the output is in text mode on platforms that have a text/binary difference. If 'nonewline' is set, we will cut off the trailing newline of this given data before comparing with the one actually received by the client The file's contents must be identical to this after the test is complete. Use the mode="text" attribute if the output is in text mode on platforms that have a text/binary difference. Variables are substituted as in the section. 1 to 4 can be appended to 'file' to compare more files. One perl op per line that operates on the output file or stdout before being compared with what is stored in the test file. This is pretty advanced. Example: "s/^EPRT .*/EPRT stripped/" 1 to 4 can be appended to 'stripfile' to strip the corresponding content the contents of the upload data curl should have sent disable - disables the valgrind log check for this test
