Here are few things to look at when setting up Travis in your project

• Correct file name

    .travis.yml
  

• Inside .travis.yml file

      
    language: node_js
  
    env:
    - DATABASE_URL=postgresql://postgres@localhost:5432/<your_database_here>
  
    node_js:  
    - 12
  
    before_script:
    - psql -c 'create database  <your_database_here>;' -U postgres
    - psql -U postgres -d <your_database_here> -a -f <table_name.sql>
  
    services:
    - postgresql
  
  

  • pay attention to spaces inbetween
  • path to correct sql file.
