 ## Breaking changes
 ## v0.0.71
 - #267 Change behavior of reader conditionals: the `:clj` branch is taken when
  it occurs before a `:bb` branch.
 ## v0.0.44 - 0.0.45
 - #173: Rename `*in*` to `*input*` (in the `user` namespace). The reason for
  this is that itt shadowed `clojure.core/*in*` when used unqualified.

 ## Reader conditionals
-Babashka supports reader conditionals using the `:bb` feature:
+Babashka supports reader conditionals by taking either the `:bb` or `:clj`
 branch, whichever comes first. NOTE: the `:clj` branch behavior was added in
 version 0.0.71, before that version the `:clj` branch was ignored.
 ``` clojure
-$ cat example.clj

-## Socket REPL
+## Running tests
-Start the socket REPL like this:
+Babashka bundles `clojure.test`. To make CI scripts fail you can use a simple
 runner like this:
 ``` shell

 ## REPL
 Babashka supports both a REPL and socket REPL. To start the REPL, type:
 ``` shell
 $ bb --repl
 ```
 To get history with up and down arrows, use `rlwrap`:
 ``` shell
 $ rlwrap bb --repl
 ```
 To start the socket REPL you can do this:

   ASSERTIONS
   The core of the library is the \"is\" macro, which lets you make
   assertions of any arbitrary expression:
   (is (= 4 (+ 2 2)))
   (is (instance? Integer 256))
   (is (.startsWith \"abcde\" \"ab\"))
   You can type an \"is\" expression directly at the REPL, which will
   print a message if it fails.
       user> (is (= 5 (+ 2 2)))
       FAIL in  (:1)
       expected: (= 5 (+ 2 2))
         actual: (not (= 5 4))
       false
   The \"expected:\" line shows you the original expression, and the
   \"actual:\" shows you what actually happened.  In this case, it
   shows that (+ 2 2) returned 4, which is not = to 5.  Finally, the
   \"false\" on the last line is the value returned from the
   expression.  The \"is\" macro always returns the result of the
   inner expression.
   There are two special assertions for testing exceptions.  The
   \"(is (thrown? c ...))\" form tests if an exception of class c is
   thrown:
   (is (thrown? ArithmeticException (/ 1 0)))
   \"(is (thrown-with-msg? c re ...))\" does the same thing and also
   tests that the message on the exception matches the regular
   expression re:
   (is (thrown-with-msg? ArithmeticException #\"Divide by zero\"
                         (/ 1 0)))
   DOCUMENTING TESTS
   \"is\" takes an optional second argument, a string describing the
   assertion.  This message will be included in the error report.
   (is (= 5 (+ 2 2)) \"Crazy arithmetic\")
   In addition, you can document groups of assertions with the
   \"testing\" macro, which takes a string followed by any number of
   assertions.  The string will be included in failure reports.
   Calls to \"testing\" may be nested, and all of the strings will be
   joined together with spaces in the final report, in a style
   similar to RSpec <http://rspec.info/>
   (testing \"Arithmetic\"
     (testing \"with positive integers\"
       (is (= 4 (+ 2 2)))
       (is (= 7 (+ 3 4))))
     (testing \"with negative integers\"
       (is (= -4 (+ -2 -2)))
       (is (= -1 (+ 3 -4)))))
   Note that, unlike RSpec, the \"testing\" macro may only be used
   INSIDE a \"deftest\" or \"with-test\" form (see below).
   DEFINING TESTS
   There are two ways to define tests.  The \"with-test\" macro takes
   a defn or def form as its first argument, followed by any number
   of assertions.  The tests will be stored as metadata on the
   definition.
   (with-test
       (defn my-function [x y]
         (+ x y))
     (is (= 4 (my-function 2 2)))
     (is (= 7 (my-function 3 4))))
   As of Clojure SVN rev. 1221, this does not work with defmacro.
   See http://code.google.com/p/clojure/issues/detail?id=51
   The other way lets you define tests separately from the rest of
   your code, even in a different namespace:
   (deftest addition
     (is (= 4 (+ 2 2)))
     (is (= 7 (+ 3 4))))
   (deftest subtraction
     (is (= 1 (- 4 3)))
     (is (= 3 (- 7 4))))
   This creates functions named \"addition\" and \"subtraction\", which
   can be called like any other function.  Therefore, tests can be
   grouped and composed, in a style similar to the test framework in
   Peter Seibel's \"Practical Common Lisp\"
   <http://www.gigamonkeys.com/book/practical-building-a-unit-test-framework.html>
   (deftest arithmetic
     (addition)
     (subtraction))
   The names of the nested tests will be joined in a list, like
   \"(arithmetic addition)\", in failure reports.  You can use nested
   tests to set up a context shared by several tests.
   RUNNING TESTS
   Run tests with the function \"(run-tests namespaces...)\":
   (run-tests 'your.namespace 'some.other.namespace)
   If you don't specify any namespaces, the current namespace is
   used.  To run all tests in all namespaces, use \"(run-all-tests)\".
   By default, these functions will search for all tests defined in
   a namespace and run them in an undefined order.  However, if you
   are composing tests, as in the \"arithmetic\" example above, you
   probably do not want the \"addition\" and \"subtraction\" tests run
   separately.  In that case, you must define a special function
   named \"test-ns-hook\" that runs your tests in the correct order:
   (defn test-ns-hook []
     (arithmetic))
   Note: test-ns-hook prevents execution of fixtures (see below).
   OMITTING TESTS FROM PRODUCTION CODE
   You can bind the variable \"*load-tests*\" to false when loading or
   compiling code in production.  This will prevent any tests from
   being created by \"with-test\" or \"deftest\".
   FIXTURES
   Fixtures allow you to run code before and after tests, to set up
   the context in which tests should be run.
   A fixture is just a function that calls another function passed as
   an argument.  It looks like this:
   (defn my-fixture [f]
      Perform setup, establish bindings, whatever.
     (f)  Then call the function we were passed.
      Tear-down / clean-up code here.
    )
   Fixtures are attached to namespaces in one of two ways.  \"each\"
   fixtures are run repeatedly, once for each test function created
   with \"deftest\" or \"with-test\".  \"each\" fixtures are useful for
   establishing a consistent before/after state for each test, like
   clearing out database tables.
   \"each\" fixtures can be attached to the current namespace like this:
   (use-fixtures :each fixture1 fixture2 ...)
   The fixture1, fixture2 are just functions like the example above.
   They can also be anonymous functions, like this:
   (use-fixtures :each (fn [f] setup... (f) cleanup...))
   The other kind of fixture, a \"once\" fixture, is only run once,
   around ALL the tests in the namespace.  \"once\" fixtures are useful
   for tasks that only need to be performed once, like establishing
   database connections, or for time-consuming tasks.
   Attach \"once\" fixtures to the current namespace like this:
   (use-fixtures :once fixture1 fixture2 ...)
   Note: Fixtures and test-ns-hook are mutually incompatible.  If you
   are using test-ns-hook, fixture functions will *never* be run.
   SAVING TEST OUTPUT TO A FILE
   All the test reporting functions write to the var *test-out*.  By
   default, this is the same as *out*, but you can rebind it to any
   PrintWriter.  For example, it could be a file opened with
   clojure.java.io/writer.
   EXTENDING TEST-IS (ADVANCED)
   You can extend the behavior of the \"is\" macro by defining new
   methods for the \"assert-expr\" multimethod.  These methods are
   called during expansion of the \"is\" macro, so they should return
   quoted forms to be evaluated.
   You can plug in your own test-reporting framework by rebinding
   the \"report\" function: (report event)
   The 'event' argument is a map.  It will always have a :type key,
   whose value will be a keyword signaling the type of event being
   reported.  Standard events with :type value of :pass, :fail, and
   :error are called when an assertion passes, fails, and throws an
   exception, respectively.  In that case, the event will also have
   the following keys:
     :expected   The form that was expected to be true
     :actual     A form representing what actually occurred
     :message    The string message given as an argument to 'is'
   The \"testing\" strings will be a list in \"*testing-contexts*\", and
   the vars being tested will be a list in \"*testing-vars*\".
   Your \"report\" function should wrap any printing calls in the
   \"with-test-out\" macro, which rebinds *out* to the current value
   of *test-out*.
   For additional event types, see the examples in the code.
