There are 5 ways to run only specific tests with Elixir

  1. run a single file with mix test path_to_your_tests/your_test_file.exs
    This will run all test defined in your_test_file.exs

  2. run a specific test from a specific test file by adding a colon and the line number of that test
    for example mix test path_to_your_tests/your_test_file.exs:12 will run the test at line 12 of your_test_file.exs

  3. define a tag to exclude on your test methods

    defmodule MyTests do     @tag disabled: true     test "some test" do         #testtesttest     end end 

    on the command line execute your tests like this
    mix test --exclude disabled

  4. define a tag to include on your test methods

    defmodule MyTests do     @tag mustexec: true     test "some test" do         #testtesttest     end end 

    on the command line execute your tests like this
    mix test --only mustexec

  5. Generally exclude some tagged tests by adding this to your test/test_helper.exsfile
    ExUnit.configure exclude: [disabled: true]

Warning: Mix has an --include directive. This directive is NOT the same as the --only directive. Include is used to break the general configuration (exclusion) from the test/test_helper.exsfile described under 4).

For some reason googling for elixir mix include testsor the like never shows up on my search results therefore I have written this entry and its answer. For more info, see the Mix documentation.
