Testing ASP.NET Core Docker Container with Travis CI - bash

Question

So I've configured my .travis.yml to build and test my ASP.NET Core project, but now I've to configure it to run in docker. So far so good, I've the Dockerfile for the build, but then I started to figure:
Should I run the testing inside the Docker Container or outside? Or Does it even matter?
If I should do it inside how could this be achieved? since dotnet test doesn't have **/*/ support and my container doesn't run my bash script.
UPDATE:
Or should I build and test outside and later create the dockerimage?
The Dockerfile is:
FROM microsoft/dotnet:latest
ARG source=.
WORKDIR /usr/src/project
COPY $source .
RUN dotnet restore
EXPOSE 5000
CMD dotnet build **/*/project.json
And the .sh is:
#!/bin/bash
cd test/
for D in `find ./ -maxdepth 1 -type d`
do
if [ -a ./project.json ]
then
( cd ${D}; dotnet test;)
fi
done
Any suggestions are greatly appreciated.

Answer 1

So I decided that the docker build and publish should only be done if the build and test succeeded
.travis.yml
language: csharp
sudo: required
solution: Solution.sln
mono: none
dotnet: 1.0.0-preview2-1-003177

    - npm install -g bower
    - npm install -g gulp
before_script:
    - chmod a+x ./scripts/test.sh

    - dotnet restore && dotnet build **/*/project.json
    - ./scripts/test.sh --quite verify
    - if [ "$TRAVIS_BRANCH" == "master" ] ; then
      dotnet publish --no-build src/Main -o publish/ ;
      docker build -t project . ;
      fi
    
after_success:
    - if [ "$TRAVIS_BRANCH" == "master" ] ; then
