My automation tests use Cucumber and Geb. I am trying to create a browser
object at the beginning of my test execution in the cucumber before hooks.
To share the browser object, I am trying to use Geb biding but when I
create a class variable bindingUpdater and then trying to use it then I am
getting error. Can someone help me and explain what is going on. Should I
only be using the env.groovy file to use binding?
Following is the code which I am trying in my machine ( copied the code
from Marcin's repo
https://github.com/geb/geb-example-gradle/tree/master/src/test)
package hooks
import geb.Browser
import geb.binding.BindingUpdater
import io.cucumber.java.After
import io.cucumber.java.AfterStep
import io.cucumber.java.Before
import io.cucumber.java.BeforeStep
class Hooks {
BindingUpdater bindingUpdater
Browser theBrowser
@Before
public void createBrowser() {
if (!bindingUpdater.binding.hasVariable('browser')) {
theBrowser = new Browser()
bindingUpdater = new BindingUpdater(bindingUpdater.binding,
theBrowser)
bindingUpdater.initialize()
} else {
// save for later screenshot taking
theBrowser = browser
}
go "/cart"
}
*Error*
