Two class files are not running continuously, second class files fails to run due to null pointer

[SreenivasanM]

Please find the below error message.

FAILED CONFIGURATION: @AfterMethod afterMethod([TestResult name=LoginReports status=FAILURE method=Reports.LoginReports()[pri:0, instance:com.test.Reports@343f4d3d] output={null}]) java.lang.NullPointerException at com.extentreports.BaseExample.afterMethod(BaseExample.java:28)

If I run both the files individually it works, running as a suite fails in second class file. Please help out to solve the issue

@anshooarora - Could you please give some inputs on my tickets ?

Are you running them parallel? As classes, or methods?

I am assuming you are running both classes parallel - in which case, I would recommend using ExtentTestManager to manage your tests. A very basic design pattern is shown here: http://extentreports.relevantcodes.com/java/#parallel-classes. If not, you would have to manage a single test instance per class and you won't receive NullPointers.
