Question

I have following jar files added to my project :

2. cucumber-junit 1.2.5
3. cucumber-java 1.2.5
4. cucumber core 1.2.5
5. cucumber jvm-deps 1.0.5
6. cobetura 2.1.1

I am getting an error when I try to run test runner class:

 cucumber.runtime.CucumberException: Failed to instantiate class stepDefinition.Test_steps

The issue is on the second line of the code below since the "driver" object is null when the "wait" is initialized and that causes a NullPointerException.

private static WebDriver driver = null;
WebDriverWait wait = new WebDriverWait(driver, 60);

You should initialize the "driver" on a Before hook or initialize the "wait" after the "driver" has been initialized.
