[browser] EP testing

dev tools profiler

• dev tools only, manual test
• AOT, interp, jiterp
• callspec and instrumentation

event pipe profiler

• AOT, interp, jiterp
• callspec to filter visible methods
• manual testing: dev tools - download, open in VS, find expected calls
• manual testing: with ds-router, dotnet-trace, open in VS, find expected calls
• WBT:
  • use JS API to get promise of .nettrace bytes
  • upload the file via HTTP
  • parse and validate that trace contains expected method call

gc dump

• manual testing: dev tools - download, open in VS, find expected classes
• manual testing: with ds-router, dotnet-gcdump collect, dotnet-gcdump convert, open in VS, find expected classes
• WBT:
  • use JS API to get promise of .nettrace bytes
  • upload the file via HTTP
  • parse and validate that dump contains expected classes

counters trace

• manual testing: dev tools - download, open in VS, find expected counters, values
• manual testing: with ds-router, dotnet-counters collect, open in VS, find expected counters, values
• WBT:
  • use JS API to get promise of .nettrace bytes
  • upload the file via HTTP
  • parse and validate that dump contains expected counters, values

performance

• manually test all above on some real life app, rather than empty template

usability

• provide feedback about ergonomy and future enhancements

notes

.nettrace messages could be parsed and validated using Microsoft.Diagnostics.NETCore.Client
See IpcMessage
