java JMeter：如何在每次迭代的日期范围内将日期增加 +1

JMeter : How to increment dates by +1 within date ranges for every iteration

提问by user3523837

I want to increment by 1 day 2 dates at every iteration using Jmeter i.e.

我想在每次迭代中使用 Jmeter 增加 1 天 2 日期，即

• Date1 : 2014/01/01 (iteration1 = 2014/01/02) , (iteration1 = 2014/01/03) etc

• Date 2 : 2014/09/01 (iteration1 = 2014/09/02) , (iteration1 = 2014/01/03) etc

• Date1 : 2014/01/01 (iteration1 = 2014/01/02) , (iteration1 = 2014/01/03) 等等

• 日期 2 : 2014/09/01 (iteration1 = 2014/09/02) , (iteration1 = 2014/01/03) 等

How can I do it ?

我该怎么做 ？

For JMeter specifics:

对于 JMeter 细节：

1. Add User Defined Variableselement to set initial date values like

   • DATE1=2014/01/01
   • DATE2=2014/09/01

2. Add a Beanshell PreProcessoras a child of the request where you need these updated dates. Put the following code into the PreProcessor's "Script" are:

   import java.text.SimpleDateFormat; // necessary
   import java.util.Calendar; // imports
   import java.util.Date;
   
   SimpleDateFormat sdf = new SimpleDateFormat("yyyy/MM/dd"); // define date format
   Date date1 = sdf.parse(vars.get("DATE1")); // get DATE1 from User Defined variables
   Date date2 = sdf.parse(vars.get("DATE2")); // get DATE2 from UDV
   
   Calendar cal = Calendar.getInstance(); // get Calendar instance
   cal.setTime(date1); // set Calendar's time to be DATE1
   cal.add(Calendar.DAY_OF_YEAR,1); // add 1 day to DATE1
   date1 = cal.getTime(); // set the new value for date1
   vars.put("DATE1",sdf.format(date1)); // update DATE1 JMeter variable
   
   cal.setTime(date2); // set Calendar time to DATE2
   cal.add(Calendar.DAY_OF_YEAR,1); // add 1 day
   date2 = cal.getTime(); // set the new value for date2
   vars.put("DATE2",sdf.format(date2)); // update DATE2 JMeter variable
   
   log.info("DATE1=" + vars.get("DATE1")); // print value of DATE1 to jmeter.log
   log.info("DATE2=" + vars.get("DATE2")); // print value of DATE2 to jmeter.log 
   

1. 添加用户定义的变量元素以设置初始日期值，例如

   • DATE1=2014/01/01
   • DATE2=2014/09/01

2. 添加一个Beanshell PreProcessor作为您需要这些更新日期的请求的子项。将以下代码放入预处理器的“脚本”中：

   import java.text.SimpleDateFormat; // necessary
   import java.util.Calendar; // imports
   import java.util.Date;
   
   SimpleDateFormat sdf = new SimpleDateFormat("yyyy/MM/dd"); // define date format
   Date date1 = sdf.parse(vars.get("DATE1")); // get DATE1 from User Defined variables
   Date date2 = sdf.parse(vars.get("DATE2")); // get DATE2 from UDV
   
   Calendar cal = Calendar.getInstance(); // get Calendar instance
   cal.setTime(date1); // set Calendar's time to be DATE1
   cal.add(Calendar.DAY_OF_YEAR,1); // add 1 day to DATE1
   date1 = cal.getTime(); // set the new value for date1
   vars.put("DATE1",sdf.format(date1)); // update DATE1 JMeter variable
   
   cal.setTime(date2); // set Calendar time to DATE2
   cal.add(Calendar.DAY_OF_YEAR,1); // add 1 day
   date2 = cal.getTime(); // set the new value for date2
   vars.put("DATE2",sdf.format(date2)); // update DATE2 JMeter variable
   
   log.info("DATE1=" + vars.get("DATE1")); // print value of DATE1 to jmeter.log
   log.info("DATE2=" + vars.get("DATE2")); // print value of DATE2 to jmeter.log 
   

Being executed for 3 times it provides the following output:

执行 3 次后，它提供以下输出：

2014/08/30 10:11:13 INFO  - jmeter.util.BeanShellTestElement: DATE1=2014/01/02 
2014/08/30 10:11:13 INFO  - jmeter.util.BeanShellTestElement: DATE2=2014/09/02 
2014/08/30 10:11:13 INFO  - jmeter.util.BeanShellTestElement: DATE1=2014/01/03 
2014/08/30 10:11:13 INFO  - jmeter.util.BeanShellTestElement: DATE2=2014/09/03 
2014/08/30 10:11:13 INFO  - jmeter.util.BeanShellTestElement: DATE1=2014/01/04 
2014/08/30 10:11:13 INFO  - jmeter.util.BeanShellTestElement: DATE2=2014/09/04 

1. Refer to the variables as ${DATE1}and ${DATE2}where required.

1. 参考变量${DATE1}和${DATE2}所需的地方。

In JMeter:

在 JMeter 中：

0/ First install Groovy:

0/ 首先安装Groovy：

• Download it from http://groovy.codehaus.org/, current version as of today is 2.3.6

• Unzip the file and find folder embeddableand copy groovy-all-2.3.6.jar in jmeter/lib folder

• Restart JMeter

• That's it !

• 从http://groovy.codehaus.org/下载，截至今天的当前版本是 2.3.6

• 解压文件，找到可嵌入文件夹，将 groovy-all-2.3.6.jar 复制到 jmeter/lib 文件夹中

• 重启 JMeter

• 而已 ！

1/ Add User Defined Variableselement to set initial date values like this:

1/ 添加用户定义的变量元素来设置初始日期值，如下所示：

- DATE1=2014/01/01
- DATE2=2014/09/01

2/ The recommended way to do this for REDUCED SYNTAX, PERFORMANCE and LANGUAGE POWERis to use Groovy+ JSR223 PreProcessor, configure it this way:

2/ 为REDUCED SYNTAX, PERFORMANCE 和 LANGUAGE POWER执行此操作的推荐方法是使用Groovy+ JSR223 PreProcessor，按以下方式配置：

3/ Paste this code in JSR 223 PreProcessor:

3/ 将此代码粘贴到 JSR 223 预处理器中：

 final String DATE_PATTERN = "yyyy/MM/dd";  
 def d1Plus1 = Date.parse(DATE_PATTERN, vars["DATE1"] ) + 1;
 def d2Plus1 = Date.parse(DATE_PATTERN, vars["DATE2"] ) + 1;
 vars.put("DATE1", d1Plus1.format(DATE_PATTERN));
 vars.put("DATE2", d2Plus1.format(DATE_PATTERN));

4/ Refer to your variables as ${DATE1}and ${DATE2}

4/ 将您的变量称为${DATE1}和${DATE2}

5/ Running this Plan show this result:

Here is an example:

下面是一个例子：

• Function to add a number of days to a Calendar:

  void addDay(Calendar calendar, int offsetDay) {
      calendar.add(Calendar.DAY_OF_YEAR, offsetDay);
  }
  

• Example with 5 iterations (from 2014/01/01):

  Calendar calendar = Calendar.getInstance();
  calendar.set(2014, Calendar.JANUARY, 1);
  
  for (int i = 0 ; i < 5; i++) {
      addDay(calendar, 1);
  
      // Only for preview sample (if sdf = new SimpleDateFormat("yyyy/MM/dd");)
      System.out.println(sdf.format(calendar.getTime()));
  }
  

• 将天数添加到 a 的函数Calendar：

  void addDay(Calendar calendar, int offsetDay) {
      calendar.add(Calendar.DAY_OF_YEAR, offsetDay);
  }
  

• 5 次迭代的示例（从 2014/01/01 开始）：

  Calendar calendar = Calendar.getInstance();
  calendar.set(2014, Calendar.JANUARY, 1);
  
  for (int i = 0 ; i < 5; i++) {
      addDay(calendar, 1);
  
      // Only for preview sample (if sdf = new SimpleDateFormat("yyyy/MM/dd");)
      System.out.println(sdf.format(calendar.getTime()));
  }
  

The output of the execution of this code would be:

执行此代码的输出将是：

2014/01/02
2014/01/03
2014/01/04
2014/01/05
2014/01/06

Hope it helps you.

希望对你有帮助。

as simple as with Groovy's goodness:

就像 Groovy 的优点一样简单：

Date end= new Date() + 5 // from now till +5 days

for( Date curr = new Date(); curr < end; curr++ ){
  println curr.format( 'dd.MM' )
}
