 (ns data-test
+  ^{:author "Michael Jerger, with contributions and suggestions by razum2um",
+    :doc "data-test separates test data from test code and allows a 
+more data driven approach for testing. In case of having huge amounts 
+of test-input & -expectations your test code will remain readable and concise. 
+data-test is founded on and compatible with `clojure.test`. Integration in your 
+test environments will work without any changes. For explicit, intentful and 
+obvious data, data-test uses aero (see: https://github.com/juxt/aero).
+
+USAGE
+Define your data test similar to deftest and express your test e.g. with 
+is macro. The given binding [input expected] will let symbols which can be 
+used in your test code.
+
+Example:
+
+(ns my.cool.project-test
+  (:require [clojure.test :refer :all]
+            [data-test :refer :all]))
+
+(defdatatest should-test-multiple-specs [input expected]
+  (is (= input expected)))
+
+Your test data are loaded as resource and therefore data has to be located in 
+classpath. The path is determined by your tests namespace and your tests 
+definition name. In given case it is 
+
+my/cool/project_test/should_test_multiple_spec.edn
+
+{:input 1
+ :expected 1}
+
+The keys :input and :expected are fixed, the values can be anything you need. 
+You can have up to 11 data specifications for each test. 
+
+my/cool/project_test/should_test_multiple_spec.[1-9].edn
+
+is a valid resource-location also.
+
+Test can be executed by using 
+
+(clojure.test/run-tests)
+
+ and will produce the usual test-output like:
+
+Running namespace tests…
+FAIL in: project_test.clj: 35: should-test-multiple-specs: project_test/should_test_multiple_specs.1.edn:
+  expected: 1
+
+  actual: (2)
+
+
+4 tests finished, problems found. 😭 errors: 0, failures: 1, ns: 1, vars: 3
+
+The test data resource used will determine the testing context."}
