How to debug tests of multiple deno projects?

[jeiea]

I was running an deno program on vscode with Control+F5, and clicked "Debug" code lens above an test. Then I got this.

 *  Executing task: C:\ProgramData\chocolatey\lib\deno\deno.EXE test --allow-all --no-check --trace-ops --unstable --inspect-wait --filter /^Given example$/ d:\Repos\test\test.ts 

Cannot start inspector server: error creating server listener: Only one usage of each socket address (protocol/network address/port) is normally permitted. (os error 10048).

 *  The terminal process "C:\ProgramData\chocolatey\lib\deno\deno.EXE 'test', '--allow-all', '--no-check', '--trace-ops', '--unstable', '--inspect-wait', '--filter', '/^Given example$/', 'd:\Repos\test\test.ts'" terminated with exit code: 1. 
 *  Terminal will be reused by tasks, press any key to close it. 

I know it's my fault that try debugging with duplicate port, but how to set different port whenever I debug test?

I tried adding "--inspect-wait=127.0.0.1:9399 to "deno.codeLens.testArgs" settings, but I got error: the argument '--inspect-wait[=<HOST_AND_PORT>]' cannot be used multiple times. Even if this worked I think I will get same error again if I debug multiple test simultaneously.

What's the recommended way?
