I opened #175 and were happy that you might have provided the solution, but I still have the same problem of unverified breakpoints. But maybe im an exception.

EDIT:
I needed to add another '/' in front of the sourceMapPathOverrides to make it work.
Is this maybe a OS-Problem, since I use windows and you probably not? 😄 Does it work for you as well when you add an additional slash?

E.g;

"sourceMapPathOverrides": {
          "/./*": "${webRoot}/*",
          "/src/*": "${webRoot}/*",
          "/*": "*",
          "/./~/*": "${webRoot}/node_modules/*"
        }

@WtfJoke, it does. I'll update it.

LGTM. Thanks @alan-agius4

Also experiencing this issue. I read through issue #175 and this one but when the debugger starts and tests run, all breakpoints are showing as unverified.
