1. Rename goto_engineering_post_page/2 to visit_engineering_path/2 for better accuracy (used for both post pages and tag pages) 2. Simplify Makefile test target by removing explicit ecto.create and ecto.migrate commands (mix test handles migrations automatically) 3. Update blog_test.exs header comment to reflect actual changes made 4. Move Sandbox alias to top level in data_case.ex

This module defines the setup for tests requiring

You may define functions here to be used as helpers in

your tests.

Finally, if the test case interacts with the database,

we enable the SQL sandbox, so changes done to the database

are reverted at the end of every test. If you are using

PostgreSQL, you can even run database tests asynchronously
|
|
by setting `use Firehose.DataCase, async: true`, although
|
|
this option is not recommended for other databases.
