[RemoteTestNG] detected TestNG version 6.8.2

Is this happening because of testng version conflicts? I am stuck on this since past many days.

Answer 1

On console : detected TestNG version 6.8.2 and in your folder structure , it is : 6.12

You should update your TestNG jar and re-configure the latest one in your buildpath. You can download the latest from here .

Answer 2

You have to match your TestNG version install in Eclipse and your TestNG dependency.

You can't run TestNG dependency of 7.1.0 with TestNG Software 6.14 installed in your eclipse.

You can install your compatible TestNG version from here

Follow these steps to install/upgrade TestNG version in your eclipse:
