Thanks a lot it worked..

You're welcome.

I hope you have good performance test. ^^

@aizaimenghuangu

sorry

ngrinder test results need to be optimized

JunHo Yoon

@junoyoon

Could u post this on the issue list? It's better place for new req.

@aizaimenghuangu

Test result is not intuitive, multiple test results cannot be compared

Hi All, I am unable to run the Groovy Script Sample as i am getting the following error..

Please do the needful

looks like JUnit Version mismatch.. but i am not sure where i can fix this issue..

JunHo Yoon

@junoyoon

Yes

Ngrinder is only compatible with junit 4.8

So see your pom.xml and exclude junit wrong dependency

Sendil

@Senthilsivam41

ok sure.. i will check

Sendil

@Senthilsivam41

Thanks JunHo Yoon... it fixed the issue with Junit compilation error..

For Groovy scripts, where i need to copy the spring-context.xml file.. because it is not picking from lib folder

Sendil

@Senthilsivam41

i figured out this issue.. thanks

geunwoo son

@songeunwoo

have a nice day~^^

JunHo Yoon

@junoyoon

Good

I am facing issue with the groovy script on NGrinder.. after resolving all the issues with my spring-executable-jar.. now it is failing at the groovy script itself

nGrinder v3.4

any idea why it is throwing this error .. any import missing in my script ?

JunHo Yoon

@junoyoon

U seems that u e using some library which is compiled with jdk8 and recording it

Sendil

@Senthilsivam41

which library you meant it is my pom.xml file or the environment in which grinder console/agent is running..

JunHo Yoon

@junoyoon

Would u post your script?

i tried setting up ngrinder console and agent running oracle jvm rather open jdk jvm.. since i am compiling the code in oracle jvm.. even after this change i am getting the same error message

executable jar is built with spring framework.. so i added shade plugin to build this jar.. as the assembly jar plugin is not working as executable..

i mean the maven build

Sendil

@Senthilsivam41

Is there a problem to invoke Spring code from Groovy script ?

hI all, when I validate script ,have some error.

@junoyoon

Hi.

@Senthilsivam41 actually it's the java rather than groovy.

So.. there is not much constraints on running spring lib in ngrinder.

One thing I suspect is.. the use of instrumentation library. Could you post all the dependencies which u used?

@MeYoung please post your script.

It seems just like the groovy syntax error.

@junoyoon hi. my script :

}

@Test
public void test(){

 HTTPResponse result = request.GET("http://www.baidu.com", params)

 if (result.statusCode == 301 || result.statusCode == 302) {
     grinder.logger.warn("Warning. The response may not be correct. The response code was {}.", result.statusCode); 
 } else {
     assertThat(result.statusCode, is(200));
 }

}
}

It is auto create script.

@junoyoon

@MeYoung I think u added mistakenly hidden text... so the error message is &..

Could you recreate new test with clean text "www.baidu.com"?
