How to debug using Delve inside NeoVim
This is a simple explanation on how to use delve inside NeoVim using vim-delve.
On NeoVim, add a breakpoint with :DlvAddBreakpoint and run :DlvDebug or :DlvTest.
To run a single test one can use :DlvTest -- -test.run RegexpWithTestName
Then run Delve commands as normal.
Passing command line parameters
Everything after :DlvDebug -- is the same as if the command was invoked on the command line.
:DlvDebug -- aws --resource-type iam --exclude-region global
How to run a single test
At your terminal use go test -run RegexpWithTestName <path where the tests are>. Example:
go test -v -run Test.\*Iam ./aws
Debugging single test on the command line
On your code add runtime.Breakpoint() (importing "runtime") where you want to add a breakpoint, then:
dlv test ./path -- -test.run Test.\*Iam
