; tox configuration file for running tests similar to buildbot builders.
;
; The main trial based environments are defined based on a set of tags. Each
; tag will trigger a different behavior. Multiple tags can be set for the same environment:
;
; * alldeps - install all possible dependencies.
; * nodeps - avoid installing any dependency.
; * withcov - run the tests wrapped using the coverage.
; * nocov - run the tests directly, without using the coverage wrapper.
; * wheel - build the wheel distribution
; * posix - prepare the tests to be run in a Linux/Unix/macOS environment.
; * macos - prepare the tests to be run in a macOS 10.11+ environment (superset of posix)
; * macos1010 - prepare the tests to be run in a macOS 10.10 environment (superset of posix)
; * windows - prepare the tests to be executed under Windows.
;
; There is are non-default `codecov-push` and `coveralls-push` environments
; used to push the coverage results to codecov.io and coveralls.io,
; respectively. They should be called after running both some number of
; `-withcov` environments and also `coverage-prepare`.

; For compatibility with the current buildbot infrastructure, `codecov-publish`
; combines `coverage-prepare` and `codecov-push` into a single step.
;
; A non-default `txchecker-travis` environment is used to run twistedchecker
; on travis in --diff mode
