Description

Renaming a function also renames references to it. If there is a correspondingly named test function, it'd make sense to also rename it (TestHello to TestFoo when Hello renamed to Foo). Keeping the names in sync, and reducing work burden.

Contributor guide

Research direction
Explore the gopls renaming logic in the x/tools repository. Look for how references are collected during rename and extend it to find corresponding test functions. The test function naming convention is 'Test' + function name. Ensure the rename command also updates test function names and their references.
