ActiveRecord::StatementInvalid: Could not find table

I am trying to run users_test.rb file which just has

test "the truth" do
     assert true
   end

I do have a likes table, still I am getting this error. Why so?

Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.

before test do rake db:test:prepare

Have you run rake db:migrate? Check database if the table exists. If you are working with sqlite, then call sqlite3 db/development.sqlite3 and then issue command .schema You can manually delete database db/test.sqlite3 and then re-create it with rake db:setup.

---

Have you checked your fixtures? It has happened to me that I modified a migration but the fixture staid the same, therefore causing a error.

---

Sometimes it is caused due to multiple versions of active record gems. Please uninstall all gems except one that your application is using. I faced the same problem and did same what i said. It worked.

I just had the same problem and found the solution in db/schema.rb:

# Could not dump table "xxx" because of following StandardError
#   Unknown type 'bool' for column 'yyy'

maybe this helps!

"bool" worked everywhere except for this schema.rb, but the migrations where executed correctly in development mode.
