java.lang.StackOverFlow Exception on waitFor

[raz]

I'm getting java.lang.StackOverflowError exception when using waitFor method (log file attached with full exception)

Line of code throwing exception is 

waitFor(10) { browser.$('div', class: 'LocationSearch__ResultCount-jsWbXv hXPPML').isDisplayed() }

But the following line works fine so I'm certain object can be found.

while (!browser.$('div', class: 'LocationSearch__ResultCount-jsWbXv hXPPML').isDisplayed()) { System.out.println("waiting...") }

I believe it has something to do with the clash of versions in POM file as the waitFor works fine if I update POM file to geb-core version 0.10.0 but anything higher than that causes the above issue.

Here are the properties and dependencies from the POM file:

Hi Raz,

You're the third person reporting a problem where Geb's private methods and properties are mysteriously not seen from other places in the same class when using Geb with Cucumber and Maven (for the other two see https://groups.google.com/forum/?utm_medium=email&utm_source=footer#!msg/geb-user/pHZfjoPGECg/V9sAPmaWAwAJ). Unfortunately the previous reporters did not manage to produce a minimal reproducible sample that I could play with to observe the issue and debug it. Maybe it's the third time lucky and you will be able to create something that exposes the issue and upload it to github for me to be able to take a look at?

Thanks,
Marcin

Hi Marcin,

Thanks for getting back.

I've attached a zip file of the whole project which should help you replicate the issue.

Once extracted, following command can be used from home dir to run the test and you'll see the exception.

mvn clean test -Dgeb.env=chrome -DtagArg=@US01

Only setup required is maven, chrome and JDK1.8 

Please let me know if you need anything else, hopefully the issue is resolved soon!

Raz,

This is not a problem with Geb but it's down how you setup the environment for your cucumber environment, namely mixing in the browser class into them using this.metaClass.mixin(geb.Browser) which is something you should never do. Instead you should setup your environment using the BindingUpdater, as shown in the example project at https://github.com/geb/geb-example-cucumber-jvm/blob/master/src/cucumber/resources/env/env.groovy. After removing the mixing in and using the bundle updater I was able to get the scenarios you attached to pass:

Thanks Marcin,

That seems to have fixed the StackOverFlow exception.

Now I'm getting this exception

groovy.lang.MissingMethodException: No signature of method: cucumber.runtime.groovy.GroovyWorld.contains() is applicable for argument types: (String) values: [q]

when using 

browser.$('input', name: contains('q')) << term + Keys.ENTER

instead of 

browser.$('input', name: 'q') << term + Keys.ENTER

I have attached the updated project again (as per the example you shared), can you please let me know if it's setup as it should be? Am I missing an import to use shortcut pattern methods?

Really appreciate your help.

Thanks!

This is because the binding updater does not forward methods from geb.textmatching.TextMatchingSupport onto the Browser instance. Would you mind creating an issue for that in the tracker at https://github.com/geb/issues/issues?

To workaround that issue you can override the BindingUpdater:

@InheritConstructors
class BindingUpdaterSupportingTextMatchers extends BindingUpdater {
    static public final TEXT_MATCHING_FORWARDED_BROWSER_METHODS = ["contains"]

    @Override
    BindingUpdater initialize() {
        super.initialize()

        TEXT_MATCHING_FORWARDED_BROWSER_METHODS.each {
            binding.setVariable(it, new BindingUpdater.InvocationForwarding(it, browser))
        }

        this
    }

    @Override
    BindingUpdater remove() {
        super.remove()

        TEXT_MATCHING_FORWARDED_BROWSER_METHODS.each {
            binding.variables.remove(it)
        }

        this
    }
}

and use that instead of the one provided out of the box. You will probably want to add names of additional methods from TextMatchingSupport to TEXT_MATCHING_FORWARDED_BROWSER_METHODS if you want them to work.

Another workaround would be not to use the matcher methods directly in your steps but as part of page definitions using content DSL (https://gebish.org/manual/current/#content-dsl). As far as I can tell, using text matcher methods in content definitions should work for you without any changes being needed.

Thanks Marcin, issue # 601 created.

I'm trying the workaround to override the BindingUpdater but getting the following exception:

[ERROR] Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.6.0:java (default) on project sample-test: An exception occured while executing the Java class. Failed to create Script instance for class: class features.support.BindingUpdaterSuppo
rtingTextMatchers. Reason: java.lang.reflect.InvocationTargetException: geb.binding.BindingUpdater: method <init>()V not found -> [Help 1]

What I did was

1. created a new class BindingUpdaterSupportingTextMatchers

2. placed your provided code in it

3. updated the previous binding statement 

bindingUpdater = new BindingUpdater(binding, browser)

to use the new class  

bindingUpdater = new BindingUpdaterSupportingTextMatchers(binding, browser)

Did I miss a step or did something incorrectly? Seems like it's looking for a blank constructor for BindingUpdater but can't find it because it doesn't exist yet??

Have also attached the project showing the changes.

Thanks,

Raza 

[Marcin Erdmann]

For some reason the class you added (BindingUpdaterSupportingTextMatchers) inside of the features directory is treated as a script and is being instantiated using a no arg constructor which doesn't exist, most likely by cucumber. When I moved the class to the bottom of the env.groovy file and removed the BindingUpdaterSupportingTextMatchers.groovy file then it worked for me.

Thanks Marcin for your help!

Looking forward to a fix so don't have to use this workaround.

Cheers,

Raza
