A simple configuration change in the config/test.exs file, setting the logger’s level to debug, enables developers to see the exact queries executed during Elixir application tests, aiding in debugging and optimization efforts.
Main Points
Changing logger's level to debug in test configuration helps understand database interactions.
By adjusting the logger’s level to debug in the config/test.exs file, developers can gain insight into the exact queries being executed during test runs. This change is made by updating the line config :logger, level: :warning to config :logger, level: :debug.
Insights
Updating the logger's level to debug in the `config/test.exs` file allows developers to see the exact queries being executed during tests.
This level of transparency is instrumental when trying to understand the interactions between the tests and the database, and consequently, can help in identifying inefficiencies or potential issues with database queries.
