I cannot find any pre existing unit test cases for any .jsx/.tsx files in
app-desktop/gui. The only few unit test files available were of utility functions used.
Since, my changes are mainly involved with context menu, focus of elements and selected texts in .jsx files, should a detailed manual testing instructions of the fix be sufficient ?
If you can't write test cases for a function/method and it is GUI related, yes. Please explain why no test cases were written and what you did to test it manually.
