Here is a typical example of the instructions for running tests locally
# Running tests
Write your code in `<exercise_name>.zig`.
To run the tests for an exercise, run:
zig test test_exercise_name.zig
in the exercise's root directory (replacing `exercise_name` with the name of the exercise).
Perhaps we could support the placeholders already used in TestConfigurations.
For track maintainers the file would become
# Running tests
Write your code in `{{solution_files}}`.
To run the tests for an exercise, run:
zig test {{test_files}}
in the exercise's root directory.
