Sorry for the late reply. We have discovered a breaking change in ESP-IDF 4.4 that affected unit tests, and had to resolve it. We have updated VisualGDB to support running ESP-IDF unit tests automatically. You can now use the following command line to do so:
VisualGDB.exe /runtests <file.vgdbproj> /targetpath:<full path to the .elf file> /output:<XML file with results>
It should work for all submodules/components that get linked into the same ELF file. You would need to use the following build: VisualGDB-5.6.104.4547.msi
That said, your support period had recently expired. Although this build will work with your key, we advise renewing your key here to get access to further VisualGDB updates and technical support.
