Script Stopped by error, reason unclear

This post was updated on .

Hi,

I try to run this piece of script in nGrinder:
@RunWith(GrinderRunner)
class TestRunner {

public static GTest test
public static HTTPRequest request
public static NVPair[] headers = []
public static NVPair[] params = []
public static Cookie[] cookies = []

@BeforeProcess
public static void beforeProcess() {
HTTPPluginControl.getConnectionDefaults().timeout = 6000
test = new GTest(1, "http://localhost:8080/")
request = new HTTPRequest()
grinder.logger.info("before process.");
}

@BeforeThread
public void beforeThread() {
grinder.logger.info("before thread 1.");
test.record(this, "test")
grinder.logger.info("before thread 2.");
grinder.statistics.delayReports=true;
grinder.logger.info("before thread 3.");
}
...more...

But in nGrinder it is stopped because of an error according to the GUI.

In the log I see this:

Tests resulting in error only contribute to the Errors column.

So the "Final statistics for this process:" are collected, but afterwards it stopped.

Could you please help me with this?
I really don't understand what's causing this issue. When I run this script in Eclipse with JUnit it runs fine without errors.

Thanks in advance!

Re: Script Stopped by error, reason unclear

Does you script work from within your IDE (Eclipse, IntelliJ)?

Re: Script Stopped by error, reason unclear

Hi,

Yes, my script runs fine in Eclipse, so syntactically it looks OK.
Is there a way to retrieve more information about the cause or location of the script error?

Administrator

Which path did u install agent?
agent should be installed in the path which doesn't contain space.

Hi,

For the time being I installed the agent on "C:\Temp\ngrinder-agent".
This is in the agent.conf:
common.start_mode=agent
agent.controller_host=localhost
agent.controller_port=16001
agent.region=NONE
#agent.host_id=
#agent.server_mode=true

# provide more agent java execution option if necessary.
#agent.java_opt=
# set following false if you want to use more than 1G Xmx memory per a agent process.
#agent.limit_xmx=true
# please uncomment the following option if you want to send all logs to the controller.
#agent.all_logs=true
# some jvm is not compatible with DNSJava. If so, set this false.
#agent.enable_local_dns=false

I also see in the downloadable zipfile that my script has ended and run correctly:

But still there's a SCRIPT ERROR in the gui.

You may record wrong method.

Do you have the test method named "test()"?

Re: Script Stopped by error, reason unclear

Hi,

I indeed didn't have the function test(), but I had this in my script:

@Test
public void test1(){...}
Now I change it, it's working!!

But when I have a look on this page, there's also no test() method: http://www.cubrid.org/wiki_ngrinder/entry/how-to-run-the-multiple-tests-with-different-weight-groovy-way

How should I use the @RunRate in this case?

junoyoon

Re: Script Stopped by error, reason unclear

Administrator

if so, you have to change

test.record(this, "test")

to

test.record(this, "your_test_method_name")

so that your_test_method_name method can be recorded.

Re: Script Stopped by error, reason unclear

Thanks!! This was indeed the issue. Now it's running fine.

It looks like the @RunRate-annotation is giving errors in combination with the setting "Run Count". In that case I get the error "[ERROR] All agents are unexpectedly lost".
To solve this error I changed the Test Configuration from "Run Count" to "Duration". Is it a known bug that @RunRate and "Run Count" isn't a good combination?
