Missing test execution [MSSQL] [Travis-ci]

[Incognito]

Presently there are no tests running against a MSSQL environment on Travis.

In theory this should be possible to do via adding a job like this:

    - name: MSSQL
      php: 7.4
      env: DB=mssql
      install:
        - >
          docker run \
          -d \
          -e 'ACCEPT_EULA=Y' \
          -e 'SA_PASSWORD=yourStrong(!)Password' \
          -p 1433:1433 \
          mcr.microsoft.com/mssql/server:2017-latest
        - rm -f ~/.phpenv/versions/$(phpenv version-name)/etc/conf.d/xdebug.ini
        - composer install -v

There will be some other steps need however:

• Creating the build setup scripts for MSSQL: tests/bin/setup.mssql.sh, tests/mssql.phpunit.xml, tests/bin/phpunit.mssql.sh
• Writing the actual MSSQL-friendly-syntax for these setup scripts, ports, password, etc. All the basic setup stuff isn't done for us out-of-the-box.
• Installing the cli-client to run mssql commands against (or pass it through docker exec, that's also possible)
• Installing the right PDO drivers for MSSQL
