Example: Adding Database
● A database is a common requirement● Include schema in repo● Include data in repo● Load database before testing
Example: Adding Database
● A database is a common requirement● Include schema in repo● Include data in repo● Load database before testing● “before_script” (in .travis.yml)
Example: Adding Database
before_script: - mysql -e 'create database my_db;' - mysql -D my_db < db/load_db.sql
Example: Connecting to Database
● TravisCI sets up a database user
