java date to epoch milliseconds

to a target format storing the result optionally in the variable name. For full details on using BeanShell, please see the BeanShell web-site at http://www.beanshell.org/. Your regular expression might find numerous matches. The encoding to be used to read the file. computed by this function. This allows one to read a string from a file, and process any variable references in it. Attempts to interpret the string s as a representation of a date and time. When a filename is first encountered, the file is opened and read into an internal The digest function returns an encrypted value in the The intSum function can be used to compute the sum of two or more integer values. is a formatting character, For example, given the following variables: This can be used in conjunction with CSV Dataset, for example be treated as another long value to be added. The value of 1 was chosen because it is valid for common test variables such from datetime import datetime, timezone dt_ts = datetime. The logn function logs a message, and returns the empty string. In this case, the output is always printed - it does not depend on the current log setting. utc) print (dt_ts) Output: 2000-01-31 06: 20: 22 + 00: 00. and returns the original string. (The path can be relative to the JMeter launch directory) ), The log function logs a message, and returns its input string. Jexl can also create classes and call methods on them, for example: The V (variable) function returns the result of evaluating a variable name expression. unless the maximum loop count has been reached. the sequence number is interpreted as a loop count, and the file will be used at most "end" times. JMeter allows the expression to contain multiple statements. The format to be passed to DateTimeFormatter (for input data parsing and output formating). the filename case is significant to the function, even if the OS doesn't care, "bread" & 'butter' a3bc6900fe2b2fc5fa8a601a4a84e27a079bf2c581d485009bc5c00516729ac7, AVARO OMNIA DESUNT, INOPI PAUCA, SAPIENTI NIHIL, Java Platform, Standard Edition Nashorn User's Guide, http://www.oracle.com/technetwork/java/javase/javase7locales-334809.html, return a date in various formats with the specified amount of seconds/minutes/hours/days added, log (or display) a message (and return the value), log (or display) a message (empty return value), Use an XPath expression to read from a file, Convert a date or time from source to target format, Generate a digest (SHA-1, SHA-256, MD5), generate random date within a specific date range, extracts an element from the values of a set of variables separated by, evaluate an expression stored in a variable, generate Unicode char values from a list of numbers, quote meta chars used by ORO regular expression, parse previous response using a regular expression, Process strings containing Java escapes (e.g. that you wish to use in your template string, be sure to surround in parentheses. If the property value cannot be found, and no default has been supplied, it returns the property name. They are mainly intended for use in file names etc. a XPath expression to match nodes in the XML file. For both the epoch-second and nanosecond parts, a larger value is always later on the time-line than a smaller value. (*) means that this is set before the init file, if any, is processed. For example, "/1000" returns the current time in seconds since the epoch. A function call looks like this: Where "__functionName" matches the name of a function. (unless those properties were defined elsewhere! feather, and the Apache JMeter logo are because they are expecting numbers, and thus will not accept a function. JSR223 code with. 3. and a warning message will be written to the JMeter log file. This could be used to replace the DOMAIN field of all HTTP requests, for example - making it a simple so variable names passed as parameters will not be set up, and variable references will not work, The language code must be lowercase. __split now deletes the first unused variable in case it was set by a previous split. sample init file in the bin directory: BeanShellFunction.bshrc. The separator must be an underscore (, The algorithm to be used to encrypt The RandomFromMultipleVars function returns a random value based on the variable values provided by Source Variables. and variable name. If using optional sequence numbers, the path name should be suitable for passing to DecimalFormat. (The path is absolute), The encoding to be used to write to the file. to string (after it). ${__P(hostname,www.dummy.org)} - return value of property hostname or www.dummy.org if not defined See also __char() above. The global counter - "FALSE" - is separately maintained by each counter instance. Uses StringEscapeUtils#escapeXml10(String) from Commons Lang. Example: This is the template string that will replace Following this pattern will ensure that your tests are performant by ensuring that the Groovy can be cached. With built-in functions users can compute new values at run-time based on previous response data, which ), using the syntax for user-defined values. For example in: Format string for DateTimeFormatter (default. See also __unescape(), below. In the examples above, the first function call would return 7, If the format matches "/ddd" (where ddd are decimal digits), then the function returns the current time in milliseconds divided by the value of ddd. expression (provided by user). The StringFromFile function can be used to read strings from a text file. If each user's values is incremented separately, Each time the function is called, the next match will be returned. However the function execute() method is synchronised. The time function returns the current time in various formats. in which case the user has full control over the variable name that is used. This type of replacement is possible without functions, but was less convenient and less intuitive. If you want to enter columns containing commas, then you will need Some systems store that is like counting the number of iterations through the test plan. will use the property "xpath.file" as the file name Imagine that the variable myVar changes with each transaction, the Groovy above cannot be cached as the script changes each time. A reference name for reusing the value computed by this function. The XPath function reads an XML file and matches the XPath. Parentheses surround the parameters sent to the function, for example ${__time(YMD)} an index will be created for that entity, and that index will be kept up to date. If no nodes matched, then the function will return the empty string, The TestPlanName function returns the name of the current test plan (can be used in Including Plans to know the name of the calling test plan). Multiple __counter function calls in the same iteration won't increment the value further. to be applied to the response data. If a function parameter contains a comma, then be sure to escape this with "\", otherwise JMeter will treat it as a parameter delimiter. A reference name for reusing the value Uses StringEscapeUtils#escapeHtml(String) from Commons Lang. ${__StringFromFile(PIN#'. to a string containing the actual Unicode characters corresponding to the escapes. For possible algorithms See MessageDigest in, The String which case will be changed, The mode to be used to change case, for example for, Path to the file name. is easier to use. the second would return 1 and the last would return www.dummy.org The UUID function returns a pseudo random type 4 Universally Unique IDentifier (UUID). It will grab all matches. The thread number function simply returns the number of the thread currently This allows one to add characters to fields which are otherwise tricky (or impossible) to define via the GUI. This allows one to add arbitrary character values into fields. These values are generated fresh for every To convert milliseconds to seconds, first, divide the millisecond count by 1000. Functions are referenced in the same manner, but by convention, the names of computed by this function. Any parts of this expression Note that a different Interpreter is used for each independent occurrence of the function The Property Name to be used to check if defined, The Variable Name to be used to check if defined, The String If you need to include a comma in your parameter value, escape it like this: '. The string with URL encoded chars to decode. If the attempt is successful, the time indicated is returned represented as the distance, measured in milliseconds, of that time from the epoch (00:00:00 GMT on January 1, 1970). This can be used to evaluate nested variable references (which are not currently supported). as the name of a sourced file. If the format string is omitted, then the function returns the current time in milliseconds since the epoch. Here's an example of what you want/need to do (assuming time zone is not involved here): String myDate = "2014/10/29 This function does not work in any Configuration elements (e.g. label) of the current sampler. In the sixth parameter, you can specify You can also convert milliseconds to date & time and the other way around. List of functions, loosely grouped into types. If your plan requires a high number of threads The __isVarDefined function returns true if variable exists or false if not. Note there is a Debug Sampler The threadNum() function won't work (and does not make sense at test plan level). (The path can be relative to the JMeter launch directory), File encoding if not the platform default. (though #. separate, or to use the same counter for all users. A reference name for reusing the value created by this function. When using this function please use the variables defined above rather than using string replacement to access a variable in your script. that can be used to display the values of variables etc. To prevent a formatting character from being interpreted, The __V (variable) function can be used to do this: ${__V(Var${N})}. a test tree is compiled and submitted to be run. These numbers are only locally unique with respect to their ThreadGroup, meaning thread #1 in one threadgroup The default return value from the function is the empty string. If specified, the reference name must contain at least one non-numeric character otherwise it will To be precise: the value within a java.util.Date is the number of milliseconds since the Unix epoch, which occurred at midnight January 1st 1970, UTC. The JMeter Javascript function calls a standalone JavaScript interpreter. Supports HTML 4.0 entities. Java.type("org.apache.jmeter.threads.JMeterContextService").getTotalThreads(). ${__char(165)} = (yen). System time is measured by a system clock, which is typically implemented as a simple count of the number of ticks that have transpired since some arbitrary starting date, N.B. If not specified, the default encoding is, Copyright The JavaScript expression to be executed. The timeShift function returns a date in the given format with the specified amount of seconds, minutes, hours, days or months added. There is a fr), the decimal point is "," - which means that "#." Variables, functions (and properties) are all case-sensitive. Fetch the values: in a test script, but the same Interpreter is used for subsequent invocations. Referencing a variable in a test element is done by bracketing the variable name with '${' and '}'. For example, if one has variables A1,A2 and N=1: The evalVar function returns the result of evaluating an expression stored in a variable. CSV Data Set Config element The FileToString function can be used to read an entire file. It will not automatically escape values for you, since functions can be parameters to other functions, and you should only escape values you intend as literal. The file name, encoding and reference name parameters are resolved every time the function is executed. The language code must be lowercase. This allows one to interpolate variable and function references in a string Note that the entire NodeList is held in memory. However, most fields will allow being executed. intended for use with properties defined on the command line. Function which escapes the characters in a String using HTML entities. Note that variables cannot currently be nested; i.e. The jexl function returns the result of evaluating a I am wondering if there is a way to get current milliseconds since 1-1-1970 (epoch) using the new LocalDate, LocalTime or LocalDateTime classes of Java 8. Function to decode a application/x-www-form-urlencoded string. Properties are not the same as variables. ${__Random(1,63,LOTTERY)} will use the variable 'LOTTERY' rather than 'LOTTERY'. There are two kinds of functions: user-defined static values (or variables), and built-in functions. The epoch-seconds are measured from the standard Java epoch of 1970-01-01T00:00:00Z where instants after the epoch have positive values, and earlier instants have negative values. The thread group name function simply returns the name of the thread group Input variable name. Define the property value: If the format string is omitted, then the function returns the current time in milliseconds since the epoch. Argument values that themselves contain commas should be escaped as necessary. Also, to allow it to work better with the ForEach controller, The default return value from the function is the empty string, The package java.time is introduced in Java 8, and the newly introduced classes tries to overcome the shortcomings of the legacy java.util.Date and java.util.Calendar classes. ${__char(13,10)} = ${__char(0xD,0xA)} = ${__char(015,012)} = CRLF This uses the Java method InetAddress.getLocalHost() and passes it to getHostAddress(), The javaScript function executes a piece of JavaScript (not Java!) Each thread has its own internal pointer to its current row in the file array. When the end of the file is reached, it will start reading again from the beginning, The following shorthand aliases are provided: The defaults can be changed by setting the appropriate JMeter property, e.g. If empty, the Date String field must be a epoch time. code and returns its value. See, Indicate the date in the format set by the parameter, Indicate the specified amount of seconds, minutes, hours or days to shift according to a textual Properties are global to JMeter, The CSVRead function returns a string from a CSV file (c.f. to use. Useful formatting sequences are: If more digits are required than there are formatting characters, the number will be functions begin with "__" to avoid conflict with user value names*. The Regex Function is used to parse the previous response (or the value of a variable) using any regular After this function executes, the same values can be retrieved at later times In other locales (e.g. 1999 However some variables are defined internally by JMeter. The __logn() function reference can be used anywhere in the test plan after the variable has been defined. It required users to create default config elements that would fill in blank values of Samplers. There is a Variables are local to a thread; properties are common to all threads, values for its arguments. Each time it is called it reads the next line from the file. be omitted. The original value can be returned by setting the optional 3rd parameter to "true". in the Tree View Listener. use, If using distributed testing, ensure you switch mode (see. Instead do the following, which can be cached: The split function splits the string passed to it according to the delimiter, This can be used to define common methods and variables. The reference name parameter (if supplied) is resolved every time the function is executed. Using the Function Helper, you can select a function from the pull down, and assign This means that variables persist across calls to the function. Java provide the date and time functionality with the help of two packages java.time and java.util. If a blank line is detected, this is treated as end of file - this allows Each occurrence of a function call in a test plan is handled by a separate function instance. *)">, Java.type("org.apache.jmeter.threads.JMeterContextService").getTotalThreads(), Math.floor(Math.random()*(${maxRandom}+1)), ${minRandom}+Math.floor(Math.random()*(${maxRandom}-${minRandom}+1)), ${__CSVRead(random.txt,1)}${__CSVRead(random.txt,next)}, select ${column} from ${table} where name='${name}', select age from birthdays where name='Smith'. will evaluate as "select name from customers". ${__P(group1.loops)} - return the value of group1.loops : 2: By default, the JPA @Id is used to generate a document identifier. the function at run-time. For example if UNDEF is not defined as a variable, then the value of ${UNDEF} is ${UNDEF}. run. Result can optionally be saved in a JMeter variable. additional JMeter properties are defined in jmeter.properties, user.properties or on the command line. Full-text fields are broken down into tokens and normalized (lowercased, ). Functions which are used on the Test Plan have some restrictions. The country code must be uppercase. In this case the start number is omitted, so the file name is used exactly as is. A JavaScript date is fundamentally specified as the number of milliseconds that have elapsed since the ECMAScript epoch, which is defined as January 1, 1970, UTC Sets the milliseconds for a specified date according to local time. and must be enclosed in single quotes These are listed below. JMeter trims spaces from variable names before use, so for example Date.prototype.setMinutes() Sets the minutes for a specified date according to local time. : 3 @FullTextField maps a property to a full-text index field with the same name and type. The function returns a number between one and the max number of running threads. In computer science and computer programming, system time represents a computer system's notion of the passage of time. 2022 being executed. To convert a String into a Date and vice versa you should use SimpleDateFormat class.. Also note that variables defined in a UDV element are not available until the element has been processed. on the Test Plan: Functions can reference variables and other functions, for example The *ALIAS feature allows the same file to be opened more than once, element in a test tree. These are listed below. Function which escapes the ORO Regexp meta characters, it is the equivalent of \Q \E in Java Regexp Engine. Classical Date Time API Classes This is a simplified property function which is The same epoch could also be described in other time zones, but the traditional description is in terms of UTC. The original date format. If the attempt is successful, the time indicated is returned represented as the distance, measured in milliseconds, of that time from the epoch (00:00:00 GMT on January 1, 1970). ${__unescape(\r\n)} = CRLF ${__XPath(${__P(xpath.file),${XPATH})} parameter you will be able to use: The counter generates a new number each time it is called, starting with 1 The OUT and ERR log level names are used to direct the output to System.out and System.err respectively. Some fields do not allow random strings ${__StringFromFile(PIN.DAT,,,2)} - reads PIN.DAT twice When a thread first refers to the file it will be allocated the next free row in enclose it in single quotes. The char function returns the result of evaluating a list of numbers as Unicode characters. and Http Cookie Manager, and in this case the functions are resolved in the context of the Http Sampler. The machineName function returns the local host name. This uses the Java method InetAddress.getLocalHost() and passes it to getHostName(), The machineIP function returns the local IP address. A global counter is like Note that "." and if no default value is supplied, it is assumed to be 1. in. For example, if the variable "query" contains "select ${column} from ${table}" Alternatively, the Java Request sampler can be used to create a sample containing variable references; jmeter -Jgroup1.threads=7 -Jhostname1=www.realhost.edu In this sense, time also includes the passing of days on the calendar. The Unix epoch (or Unix time or POSIX time or Unix timestamp) is the number of seconds that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap seconds (in ISO 8601: 1970-01-01T00:00:00Z).Literally speaking the epoch is Unix time 0 (midnight 1/1/1970), but 'epoch' is often used as a synonym for Unix time. functions take different arguments. StringFromFile). expanded as necessary. Some functions take arguments to trailing comments to be used. A reference name for reusing the value sample init file in the bin directory: utility.groovy. "bread" & "butter" Word+%22school%22+is+%22%C3%A9cole%22+in+french. configure them, and these go in parentheses, comma-delimited. Note that if you're using Function to unescape a string containing HTML entity escapes be in the interval -2147483648 to 2147483647. Attempts to interpret the string s as a representation of a date and time. Otherwise, the current time is passed to SimpleDateFormat. The count of variables is returned in ${VAR_n}. About java.time. is returned as the value. User Defined Variables) as these are run from a separate thread. JMeter functions are special values that can populate fields of any Sampler or other See links below for more information on JEXL expressions. The longSum function can be used to compute the sum of two or more long values, use this instead of __intSum whenever you know your values will not If present, it is displayed in the string. Path to the file name. Uses Perl5Compiler#quotemeta(String) from ORO. JMeter thread variables will have not been fully set up when the functions are processed, When supplying a default value, there is no need to provide a function name - the parameter can be set to null, and it will be ignored. Function which escapes the characters in a String using XML 1.0 entities. This site provides the current time in milliseconds elapsed since the UNIX epoch (Jan 1, 1970) as well as in other common formats including local / UTC time comparisons. ${__unescapeHtml(>&zzzz;x)} will return >&zzzz;x. The counter function instances are completely independent. the number will be inserted according to the formatting instructions. The function returns the template string with variable values filled The RandomDate function returns a random date that lies between the given start date and end date values. See the documentation for DecimalFormat for full details. Note: use UTF-8 as the encoding scheme. the output will be shown in the appropriate Listener. Examples: Functions that require no parameters can leave off the parentheses, for example ${__threadNum}. Initial Sequence number (if omitted, the End sequence number is treated as a loop count), Final sequence number (if omitted, sequence numbers can increase without limit). Commons JEXL expression. For example when testing a banking application, 100s or 1000s of different account numbers might be required. The counter uses an integer variable to hold the count, which therefore has a maximum of 2,147,483,647. The name of The Calendar class is an abstract class that provides methods for converting between a specific instant in time and a set of calendar fields such as YEAR, MONTH, DAY_OF_MONTH, HOUR, and so on, and for manipulating the calendar fields, such as getting the date of the next week.An instant in time can be represented by a millisecond value that is an offset from the Epoch, and "column" and "table" contain "name" and "customers", then ${__evalVar(query)} request throughout the course of the test. Also, if is returned. Result will and incrementing by +1 each time. e.g. in PIN.DAT above should not be quoted. You have four choices: Default value returned if no match is found. Apache, Apache JMeter, JMeter, the Apache There are no arguments for this function. However, that does not currently support multiple input files. For example one can access the JMeterContextService static methods thus: it is advised to use. If any delimiters are adjacent, "?" The expression to be evaluated. If there are multiple references to the function in a test script, each will open the file independently, The unescape function returns the result of evaluating a Java-escaped string. If you want to have a count that increments for each sample, use the function in a Pre-Processor such as User Parameters. and the contents of the variable XPATH as the expression to search for. JMeter provides a tool to help you construct The string format of a locale. Attempts to interpret the string s as a representation of a date and time. case has been changed following a specific mode. the array, so each thread will access a different row from all other threads. The setProperty function sets the value of a JMeter property. Please note that the START variables / properties represent JMeter startup time, not the test start time. For example: If an undefined function or variable is referenced, JMeter does not report/log an error - the reference is returned unchanged. If the optional start number is not specified, the path name is used as is. and 000. work as expected in locales where the decimal point is also ".") Unlike the __property function, there is no option to save the value in a variable, See below for examples. remember to include any necessary quotes for text strings, fromtimestamp(949299622, tz = timezone. The __dateTimeConvert function converts a date that is in source format If specified, then the value of the variable is used as the input instead of using the previous sample result. The actual parameters vary from function to function. be in lower case by default. If the function takes no arguments, the parentheses can
