- Modify the name to: obtain the product list information.
- The reference name is: name.
- The regular expression is: < TD; (.*?)<td>. Get the table information of name.
- The template is: 1, which means there is 1 parameter in the regular expression.
- The matching number is: - 1. Get all matches. (here, like the boundary extractor, 1 represents the first matching item; 2 represents the second matching item;...; n represents the nth matching item; 0 represents a matching item randomly assigned by JMeter; a negative number represents all matching items obtained).
- The default value is null.
After running, all matching parameters can be obtained in the sampler for viewing the results, as shown in Figure 16.
Figure 16 list information of all matched products
- name is null due to multiple pieces of information obtained.
- name_1: The string matched to the first record is: "zhengshantang tea industry Yuanzheng Jianya Zhengshan small black tea gift box, Wuyishan tea gift".
- name_1_g: The number of parameters matched to the first record is 1.
- name_1_g0: regular expression, and name is used for the corresponding part_ 1. The result is: "< td > zhengshantang tea industry Yuanzheng Jianya Zhengshan small black tea gift box gift Wuyishan tea gift < td >".
- name_1_g1 same as name_1. The string matched in the first record: "zhengshantang tea industry Yuanzheng Jianya Zhengshan small black tea gift box, Wuyishan tea gift".
- name_2...,name_3...,name_4... And name_5... Are the values obtained from the string responses matching the 2nd, 3rd, 4th and 5th.

No exception occurred after running. Response assertions are described in detail in section 5.3-1. 2 use BeanShell assertion 1) Right click the product list HTTP request and select "add - > assert - > BeanShell assert". Write the assertion code as shown in Figure 18.
Figure 18 BeanShell assertion for product list
2) Modify the name: product list BeanShell assertion, and then enter the following code in the script.
//Get system variables
String name1 = vars.get("name_1");
String name2 = vars.get("name_2");
String name3 = vars.get("name_3");
String name4 = vars.get("name_4");
String name5 = vars.get("name_5");
String name_matchNr = vars.get("name_matchNr");
//Judge whether the return value is consistent with the expected value
Failure = false;
if (! name1.equals("Zhengshantang tea industry Yuanzheng simple and elegant Zhengshan small black tea gift box gift Wuyishan tea gift")){
Failure = true;
FailureMessage = "name1 Information does not meet expectations";
}else if(! name2.equals("Black tea Zhengshan race Wuyishan black tea 170 g Spring tea bag 170 g Bulk new tea")){

FailureMessage = "name5 Information does not meet expectations";
}else if(!name_matchNr.equals("5")){

ailureMessage = "name_matchNr Information does not meet expectations";
}
No exception occurred after running. Thus, BeanShall asserts that although it is difficult to master, its function is more powerful. The bean shell assertion is described in detail in section 5.3-2. Note: in normal operation, you can choose between response assertion and BeanShell assertion, and you don't need to do it all. But I personally think it is recommended to use bean shell assertion here. 3.3 new version product list In the new version, only the XML file is downloaded from the server, and then the HTML file is parsed.
