I am learning and doing automated testing.
I was able to connect Firefox with selenium in the project created but now on of the experienced developer has given his code to go through and implement automation testing as per his approach using( excel approach). But when I imported his code in eclipse and copy pasted my code for firefox connectivity it shows an error saying can't connect to localhost...and firefox binary issue as well.
I read about the error, it says that version upgrade or downgrade but the same code is working in my another project. Also, I added the jar files that I have in my project.
Please advice me on the same.
