--result-json does not respect --skip-missing-interpreters-option #672

When executing tox with --result-json and --skip-missing-interpreters-option, the latter seems not to be reflected in the generated json file. Please find the sample project attached below:

To reproduce the issue simply invoke:

tox --skip-missing-interpreters --result-json toxreport.json
Tox main process exits with return code 0, but in toxreport.json file user can see the following:

"python": {
  "setup": [
    "command": [
    "setup virtualenv"
    "output": "InterpreterNotFound: xyz_unknown_interpreter",
    "retcode": "1"

In my opinion retcode here should be changed to 0 if --skip-missing-interpreters option is explicitly used.

@r2dan r2dan changed the title from --result-log does not respect --skip-missing-interpreters-option to --result-json does not respect --skip-missing-interpreters-option Nov 15, 2017

Hi @r2dan thanks for the report. Having a test reproducing this would also be great.
