Created in the spirit of testfirst.org, test-first-clj strives to teach clojure and introduce some of it's tooling at the same time. Many of today's most popular learn-to-code tools are dressed up unit tests, but using them in that environment deprives the learner of grokking the power of testing, and keeps the syntax secret.

The test-first-clj library is still very much a work in progress. If you have an idea for a kata, or would like to help port over coding exercises from another language PRs are very much welcome!

• Install lein
• Run git clone https://github.com/HenryMarshall/test-first-clj
• cd test-first-clj
• lein deps

• Run lein test-refresh :only test-first-clj.00-greet-test
• Create src/test_first_clj/00_greet.clj
• Make the tests pass!
• Kill the lein process (Control-c)
• Run lein test-refresh again, replacing 00-greet-test with the next assignment

When you first get started, clojure.test won't give you a pretty list of failing tests because it won't be able to load the dependencies. You'll see something like the following:

Exception in thread "main" java.io.FileNotFoundException: Could not locate test_first_clj/00_greet__init.class or test_first_clj/00_greet.clj on classpath.

Just create the appropriate src file to proceed.

Likewise, clojure may complain that it's "unable to resolve symbol". That likely means it can't find the appropriately named function. Create it in the src file.

Exception in thread "main" java.lang.RuntimeException: Unable to resolve symbol: greet in this context, compiling:(test_first_clj/00_greet_test.clj:7:10)

• Add different profiles.clj files in different branches to make various REPL based testilng workflows more convenient.
