hi all,
I'm trying to parallelize our tellurium tests, and am running into
frequent cases where requests through the connector give me:
Exception : com.thoughtworks.selenium.SeleniumException:
The_server_localhost_failed_to_respond_with_a_valid_HTTP_response.:
java.lang.NullPointerException
at
org.codehaus.groovy.runtime.callsite.GetEffectivePojoFieldSite.acceptGetProperty(GetEffectivePojoFieldSite.java:
43)
at
org.codehaus.groovy.runtime.callsite.AbstractCallSite.callGetProperty(AbstractCallSite.java:
237)
at
org.tellurium.connector.CustomSelenium.getActiveSeleniumSession(CustomSelenium.groovy:
76)
Is there anything that needs to be done for the selenium connector to
be thread-safe? Does it need synchronizaiton, or are lower levels in
the stack already synchronized?
My use-case is this:
I have multiple dslContexts, each of which represents a webapp (I have
2) that is being manipulated during a test. Setup is being done
through a TestNG listener, which establishes the DslContexts, does
connectUrl() on them, etc. Then my testcase begins.
As mentioned, I get frequent SeleniumExceptions when trying to use
parallel="methods" while executing.
>From looking at the code, I see the the connector isn't synchronized,
nor is the CustomSelenium object. It also would seem to me that this:
// Get the active Selenium RC session
def CustomSelenium getActiveSeleniumSession(){
DefaultSelenium sel =
com.thoughtworks.selenium.grid.tools.ThreadSafeSeleniumSessionStorage.session()
CommandProcessor processor = sel.commandProcessor
CustomSelenium csel = new CustomSelenium(processor)
/*
if(this.userExtension != null &&
this.userExtension.trim().length() > 0){
File userExt = new File(this.userExtension);
// processor.setExtensionJs(userExt.getAbsolutePath())
processor.setExtensionJs(this.userExtension)
println "Add user-extensions.js found at given path: " +
userExt.getAbsolutePath() + " to Command Processor";
}
*/
csel.customClass = this.customClass
csel.passCommandProcessor(processor)
return csel
}
would have to be thread-safe or the csel object returned back may not
always be correct -- ie: CustomSelenium would have to be protected
like DefaultSelenium is, right?
thanks!
Jason
