tests.LoginTest need to share an instance of WebDriver with utils.listener.TestListener; an possible alternative implementation using ITestContext

[kazurayam]

utils.listener.TestListner#onTestFailure() is designed to take a screenshot of the browser on a failure detected by the @Test-annotated method of tests.LoginTest. TestListener need to have a reference to the instance of WebDriver which was created by the LoginTest class.

Here we find a technical issue. The Test class creates a WebDriver instance; The Test Listener need a reference to the WebDriver instance. Then how to share the WebDriver instance between the two? There could be multiple design options. The original utils.listener.TestListner#onTestFailure() gets access to the WebDriver instance by the following 2 lines of code:

    @Override
    public void onTestFailure(ITestResult iTestResult) {
        ...
        Object testClass = iTestResult.getInstance();
        WebDriver driver = ((BaseTest) testClass).getDriver();

OK. This certainly works. However I find two issues in the original code set.

Issue1 : utils.listener.TestListener extends tests.BaseTest, which is unnecessary

I think that the author possibly forgot to erase the inheritance.

Issue2 : Should use ITestContext

we should rather use TestNG ITestContextto share the WebDriver instance between the Test class and the TestListener. Here is a brief introduction how to utilize @ITestContext`

How can we share the WebDriver instance created by a Test class to a TestListener?

See the following articale to learn about ITestContext of TestNG.
