tddreloader

This module runs inside an Erlang shell alongside development. It watches the src/ directory for changed files, and when any file changes, it recompiles, loads, and runs tests on the file.

Usage

cd myproject
erl -pa ebin -s tddreloader start

Or, in a running shell:

tddreloader:start().

Or, in a project Makefile:

shell:
  erl -pa ebin -s tddreloader start

Once tddreloader is started, it'll watch for file changes and do its thing. But if you want, you can reload stuff and run tests without starting the application.

tddreloader:reload_all() - reload everything under src/.

tddreloader:test_all() - run all tests for beams in ebin/.

How I use it

My actual workflow is to split my terminal (I use tmux for that) and run my editor (vim) over my Erlang shell. That way, every time I save a file, it triggers a compile, a reload, and running all the tests for that module.

Installing

Using erlang.mk:

DEPS = ... tddreloader ...
...
dep_tddreloader = https://github.com/Version2beta/tddreloader.git master
