Testing

​

Requirements

• Install chromedriver . It is required to run tests from ./apps/block_scout_web of the Umbrella application.
• This set of environment variables is required for each run of the test (mix test) suite:
  export MIX_ENV=test
  export POSTGRES_DB=explorer_test
  export POSTGRES_PASSWORD=postgres
  export POSTGRES_USER=postgres
  export CHAIN_ID=77
  
  Since v6.6.0, there are more flexible options for configuring the database used in testing. Refer to the TEST_DATABASE_URL and DATABASE_READ_ONLY_API_URL environment variables for more details.
  export MIX_ENV=test
  export TEST_DATABASE_URL=postgresql://postgres:postgres@postgres-host:5432/explorer_test
  export CHAIN_ID=77
  

​

Running tests

1. Build assets. cd apps/block_scout_web/assets && npm run build; cd -
2. Format Elixir code. mix format
3. Lint Elixir code. mix credo --strict
4. Run the dialyzer. mix dialyzer --halt-exit-status
5. Check the Elixir code for vulnerabilities. cd apps/explorer && mix sobelow --config; cd - cd apps/block_scout_web && mix sobelow --config; cd -
6. Lint JavaScript code. cd apps/block_scout_web/assets && npm run eslint; cd -
7. Test JavaScript code. cd apps/block_scout_web/assets && npm run test; cd -
8. Run separate test suites for the Umbrella application
   - indexer
mix do ecto.create --quiet, ecto.migrate && cd apps/indexer && mix do compile, test --no-start && cd -
   
   - explorer
mix do ecto.create --quiet, ecto.migrate && cd apps/explorer && mix do compile, test --no-start && cd -
   
   - block_scout_web
mix do ecto.create --quiet, ecto.migrate && cd apps/block_scout_web && mix do compile, test --no-start && cd -
   
   - ethereum_jsonrpc
mix do ecto.create --quiet, ecto.migrate && cd apps/ethereum_jsonrpc && mix do compile, test --no-start && cd -
