I am very new to Salesforce.
I was wondering what is the easiest way to deploy the updated Apex class from Sandbox to Production? I just made some small changes in one of our Apex classes. Since I couldn't modify the class in Production, so I made a Partial Copy Sandbox and edited the Apex class there.
After some physical tests(I didn't write any test file.), it is working good. Now how can I push the updated Apex class to Production?
I searched a bit on google, it seems like I need to download Eclipse, install Force Package, write some test coverage and etc. Do I have any easier way to make it happen?
Thank you very much!
