Is the issue reproducible on runner?

• Shell
• Maven
• Gradle
• Ant
• Eclipse
• IntelliJ
• NetBeans

I switched from version 7.8.0 to version 7.9.0 without making any changes and I started to get this error.

@bakicanboydas - Please add a sample project that can be used to reproduce this problem.

@krmahadevan I cannot share it because it is a company project, but I can share pom versions. I changed where our company name used in pom file other things that i can publish with you. I can't publish project because of NDA sorry.

@bakicanboydas - I am not asking you to share your company project, but merely asking you to please help share a sample project which I can use to reproduce the problem. Without a sample its not going to be possible to figure out what is going on.

So please help with a sample project.

[krmahadevan]

Also if you look at the stacktrace you would notice that its one of your test listeners which seem to be the source of the NullPointerException

at utils.listeners.TestListener.onStart(TestListener.java:38)

Perhaps you could help setup a breakpoint there and see what is being passed as the key/value to the ITestResult object's attributes. That should tell you what is going wrong.

[bakicanboydas]

@krmahadevan These are steps with debug for 7.9.0 result, what is different between 7.9.0 and 7.8.0 for this part?

@bakicanboydas

These are steps with debug for 7.9.0 result, what is different between 7.9.0 and 7.8.0 for this part?

It looks like your driver object is null. Please check/share how the this.driver is being instantiated to find out why it's coming up as null.

[bakicanboydas]

@krmahadevan I instantiated it in BaseTest and extend it on Listener class

[krmahadevan]

Please show the place wherein Appium is being instantiated. Your screenshot just shows where AppiumDriver is declared.

Instead of this back and forth is why I was suggesting that you please create a sample that can be used to reproduce the problem.
