Supporting two languages in travis.ci file

Question

I'm building a python package which is mostly c++ code (think numpy)

My travis file is currently

language: cpp
compiler:
  - gcc
  - clang
os:
  - linux
  - osx
dist: trusty

script: "make pcst_fast_test && ./pcst_fast_test"

notifications: 
...

But I've also written some python tests in a file called test_pcst_fast.py. Is there some way to call those from travis as well?

It seems ambiguous as to whether travis supports multiple languages in one file, but it seems like most people pull this off despite only listing one language under the language tag.

Answer 1

Travis doesn't support multiple languages per job yet.

Look at categories after_success and after_script in the Travis build lifecycle docs

Also, you can add more build scripts, they will run independently, just list them like this:

script:
    - "make pcst_fast_test && ./pcst_fast_test"
    - "./test_pcst_fast.py"

If there is no python installed (not sure about c builds), you can install it, check out this .travis.yml, it installs custom python interpreter as a dependency.
