使用范围报告时出现空指针异常

Question

I have two classes baseClass and TesCaseLoginPage . When i am trying to execute TesCaseLoginPage class without any Report/Logger (ExtentReport),Test case is getting pass. But when i am puttin extend report into my code, I am getting NullPointerException .Could you please help me

I have written report.endTest(logger); in line no 51. Tried to comment this line and then executed. This time i got same error in line no 50 ie

logger.log(LogStatus.INFO,"Browser Closed"); . So every time i am commenting error line, getting same error in new log related line only.

Error log is as below :

Answer 1

Initialize the logger in your Test.

use this line:

logger = extent.startTest("Test Name","Description");

Make it the first line even before you call the logger in your test.

For reference see Software Automata - Extent Reports in Selenium

Answer 2

I am also facing the same issue, using Extent 2.41 Keeping default file on loaction is mandatory?, if yes then what will happen in case of you are generating the file at run time and providing the new file name every time @ Upkar singh
