Jmeter interface trial

1. Create a project, import a package 1. Create javaproject2, introduce basic Lib \ ext packages in jmeter: apachejmeter_java.jar, apachejmeter_core.jar3, and introduce jmeter log package: jorphan. jar, logkit-2.0.jar, commons-logging-1.1.1.jar, avalon-framework-4.1.4.jar4, introduced httpclient-4.3.4.jar (is a set of clients based on httpcore), httpcore-4.3.2.jar (is a set of HTTP protocol implementation package) jmeter 4 classes used:

Arguments	Getdefaparameparameters() Used to obtain the number of workers on the Interface
Sampleresult	Runtest(Using amplercontext context) similar to LR action
Void	Setuptest(JavasamplercontextContext)The initialization method is similar to the init of LR and setup () in JUnit ()
Void	Teardowntest(JavasamplercontextContext)Similar to LR end and teardown () in JUnit ()

The running sequence is as follows: Getdefaparameparameters() --> Setuptest(Javasamplercontext context) --> Runtest(Javasamplercontext context) --> Teardowntest (Javasamplercontext Context)
Frequently used methods: ①. addargument ("name", "value") defines the number of transactions ②. samplestart () defines the start time of a transaction, similar to lr_start_transaction of LR, like LR, do not place irrelevant codes ③ and sampleend () between transactions to define the end of the transaction. Similar to LR's lr_end_transaction ④ and setsuccessful (true and false), set whether the execution result succeeds or fails, jmeter counts the number of successful failures, which can be reflected in the aggregation report.
Ii. Example 1: testapigetsearchsuggestion. java. This code can be used to deduce the returned data and write a file. 2. jmeter_getsearchsuggestion.java, which is the focus of this section.

Package COM. test. jmeter; import Java. io. ioexception; import Org. apache. HTTP. client. clientprotocolexception; import Org. apache. jmeter. config. arguments; import Org. apache. jmeter. protocol. java. sampler. abstract‑amplerclient; import Org. apache. jmeter. protocol. java. sampler. using amplercontext; import Org. apache. jmeter. samplers. sampleresult; public class jmeter_getsearchsuggestion extends act1_amplerclient {Private Static string label = "jmeter_getsearchsuggestion"; // defines the label name, which is displayed in the jmeter result form private string URL; public void setuptest () {// defines the initial values of the test. setuptest only uses system before the start of the test. out. println ("setuptest") ;}@ overridepublic sampleresult runtest (datagamplercontext arg0) {url = arg0.getparameter ("url"); Data = arg0.getparameter ("data"); sampleresult SR; sr = new sampleresult (); Sr. setsamplelabel (Label); testapigetsearchsuggestion T = new testapigetsearchsuggestion (); Sr. samplestart (); try {// call the method t of the interface under pressure. postjson (URL, data); Sr. setsuccessful (true);} catch (clientprotocolexception e) {Sr. setsuccessful (false); E. printstacktrace ();} catch (ioexception e) {Sr. setsuccessful (false); E. printstacktrace ();} Sr. sampleend (); // return SR for the jmeter end statistics response time mark;} public void teardowntest (datagamplercontext arg0) {super. teardowntest (arg0);} public arguments getdefaparameparameters () {// parameter number definition, which is displayed on the foreground. You can also define arguments Params = new arguments (); Params. addargument ("url", "http://gapp.test.com/merchandise/GetSearchSuggestion"); Params. addargument ("data", "Data = {\" token \ ": \" aaaaaaaaaa \ ", \" body \ ":{\" keywords \": \ "Blue Moon \" }}"); Return Params ;}}

3. After testing the main function successfully, compress it into a jar package and put it in the % jmeter_home % \ Lib \ ext folder.

Iii. Execution case 1. Execute % jmeter_home % \ bin \ jmeter. bat2. Join the thread group, Java request, view result tree, aggregate report 3. the result after running is
TIPS: shortcut key Ctrl + R execution case, CTRL + e clear execution result
