+# tapered version history
+
+## *1.0-0* (July 10, 2015)
+
++ Initial public release
+
+## *1.0-1* (July 10, 2015)
+
++ Fix rockspec: the URL for Bitbucket was wrong.
+
+## *1.1-0* (July 13, 2015)
+
++ Improve organization and coverage of tests
++ Refactor the `same` method
++ Remove `same_mt`
++ Meaningful exit statuses via `done`
++ Add CI via [drone.io][dio]
+
+[dio]: https://drone.io/bitbucket.org/telemachus/tapered/latest
+
+## *1.2.0-1* (July 19, 2015)
+
++ Clean up code using luacheck and luacov
++ Small tweaks to README and CHANGES
++ Fix version number: the previous two digit number was a mistake, based on
+ a misunderstanding of LuaRocks conventions. This is an annoying switch, but
+ better now than later. And better to do it than to live with a versioning
+ pattern I dislike.
+
+## *1.2.1-1* (December 5, 2015)
+
++ Test coverage stats are now thanks to [codecov][codecov].
++ Latest stable Lua in the 5.3 series is 5.3.2, so we test against that now.
+
+[codecov]: https://codecov.io
+
+## *2.0.0-1* (May 1, 2016)
+
++ The informational fields are now functions that return strings. This is to prevent them from violating Lua recommendations about variables such as `_VERSION`. (I've bumped the major version number since this is technically an API change, though for most users it will not require any changes on their end.)
+
+## *2.0.1-1* (May 2, 2016)
+
++ Fix a typo in the documentation.
++ Adjust the `version()` return value to show only software version, not the rockspec version as well.
+
+## *2.1.0-1* (July 21, 2016)
+
++ Update to test against Lua 5.3.3
+
+## *2.2.0-1* (February 11, 2017)
+
++ Update to test against Lua 5.3.4
++ The repo is now housed on [Github](https://github.com/telemachus/tapered)
++ CI is now provided by [Travis.ci](https://travis-ci.org/telemachus/tapered)
+
+## *2.3.0-1* (October 15, 2017)
+
++ Remove `setup()` and `teardown()`
++ Update to use luarocks 2.4.3 for testing on Travis
+
+Would you rather view the [documentation][d]?

+# tapered [![Build Status](https://travis-ci.org/telemachus/tapered.svg?branch=master)](https://travis-ci.org/telemachus/tapered) [![Coverage](https://codecov.io/gh/telemachus/tapered/branch/master/graph/badge.svg)](https://codecov.io/gh/telemachus/tapered)
+
+## Synopsis
+
+Very minimal tap testing for Lua. Arguably too minimal.
+
+## Assertions
+
+The `message` parameter is always optional. Brief messages help make test output
+clearer to readers, but are not needed if the output goes straight to another
+program for parsing.
+
++ `ok(expression, [message])` Tests whether `expression` returns a truthy
+ value.
+
++ `nok(expression, [message])` Tests whether `expression` returns a falsy
+ value.
+
++ `is(actual, expected, [message])` Tests whether `actual` is equal to
+ `expected`. The test uses `==` internally.
+
++ `isnt(actual, expected, [message])` Tests whether `actual` is not equal to
+ `actual`. The test uses `~=` internally.
+
++ `same(actual, expected, [message])` Tests whether `actual` is a deep copy
+ of `expected`. The test uses an `__eq` metamethod if one is found. Useful
+ for comparing tables.
+
++ `like(string, pattern, [message])` Tests whether `string` matches the given
+ `pattern`.
+
++ `unlike(string, pattern, [message])` Tests whether `string` does not match
+ the given `pattern`.
+
++ `pass([message])` A test that always passes. Useful as a quasi-skip with a
+ message.
+
++ `fail([message])` A test that always fails. Useful as a quasi-TODO with a
+ message.
+
++ `boom(function, args, [message])` Calls `function` with `args` as
+ parameters and checks to see if an exception is raised. Passes if an
+ exception is raised; fails otherwise. (The exception is swallowed.) The
+ `args` parameter expects a table. The table can be empty but not `nil`.
+
+## Helper method
+
+A method is available to show how many tests were run. (This output
+is required for [TAP compliance][tap], which may matter in some cases.)
+
+[tap]: http://testanything.org/tap-specification.html
+
++ `done([number])` Call this function (optionally) at the end of your test file.
+ It will print out a line in the form `1..n` where `n` is the total number
+ of tests run. This secures TAP compliance when needed. The call to `done`
+ is not otherwise required. If you don't care about TAP compliance, neither does
+ the library. If you pass the optional parameter to the method, it will check
+ whether the number of tests you expected matches the number of actual tests.
+ Thus, if can function like a traditional `plan` method. However, this method
+ should always be called *last* in your tap file, unlike `plan` methods which
+ normally start the test file.
+
+ Another reason to use `done` is if you care about the exit status of the
+ tests. Many continuous integration tools rely on tests signalling success or
+ failure via their exit status. After `done` is called, the script will exit
+ with a status of 0, indicating success, if all tests passed. If some tests
+ failed, the script will exit with a status equal to the number of failed
+ tests, indicating failure. A script will also exit with an error status if
+ there is a mismatch between the actual number of tests run and the number
+ passed to `done` as a parameter.
+
+## Varia
+
+The module provides four informational functions that return strings. They
+should be self-explanatory.
+
++ `version() -- 2.3.0`
+
++ `author() -- Peter Aronoff`
+
++ `url() -- https://github.com/telemachus/tapered.git`
+
++ `license() -- BSD 3-Clause`
+
+## Credits
+
+For the `same` method I took ideas and code from [Penlight][p], [Underscore][u],
+[luassert][l], and [cwtest][cw]. I thank all the people who worked on those.
+
+Indirect inspirations include [knock][k], [Test::More][tm], and [bats][b]—not so
+much for code as for ideas about testing and simplicity.
+
+Thanks in particular to [Pierre Chapuis][pchapuis] for help with ideas and
+getting continuous integration for tapered.
+
+An anonymous email showed me that my setup and teardown methods had a logical
+flaw. As a result, I've removed those methods. I appreciate the report.
+
+All the mistakes are mine. See [version history][c] for release details.

+program for parsing.</p>
+
+<ul>
+<li><p><code>ok(expression, [message])</code> Tests whether <code>expression</code> returns a truthy
+value.</p></li>
+<li><p><code>nok(expression, [message])</code> Tests whether <code>expression</code> returns a falsy
+value.</p></li>
+<li><p><code>is(actual, expected, [message])</code> Tests whether <code>actual</code> is equal to
+<code>expected</code>. The test uses <code>==</code> internally.</p></li>
+<li><p><code>isnt(actual, expected, [message])</code> Tests whether <code>actual</code> is not equal to
+<code>actual</code>. The test uses <code>~=</code> internally.</p></li>
+<li><p><code>same(actual, expected, [message])</code> Tests whether <code>actual</code> is a deep copy
+of <code>expected</code>. The test uses an <code>__eq</code> metamethod if one is found. Useful
+for comparing tables.</p></li>
+<li><p><code>like(string, pattern, [message])</code> Tests whether <code>string</code> matches the given
+<code>pattern</code>.</p></li>
+<li><p><code>unlike(string, pattern, [message])</code> Tests whether <code>string</code> does not match
+the given <code>pattern</code>.</p></li>
+<li><p><code>pass([message])</code> A test that always passes. Useful as a quasi-skip with a
+message.</p></li>
+<li><p><code>fail([message])</code> A test that always fails. Useful as a quasi-TODO with a
+message.</p></li>
+<li><p><code>boom(function, args, [message])</code> Calls <code>function</code> with <code>args</code> as
+parameters and checks to see if an exception is raised. Passes if an
+exception is raised; fails otherwise. (The exception is swallowed.) The
+<code>args</code> parameter expects a table. The table can be empty but not <code>nil</code>.</p></li>
+</ul>
+
+
+<h2>Helper method</h2>
+
+<p>A method is available to show how many tests were run. (This output
+is required for <a href="http://testanything.org/tap-specification.html">TAP compliance</a>, which may matter in some cases.)</p>
+
+<ul>
+<li><p><code>done([number])</code> Call this function (optionally) at the end of your test file.
+It will print out a line in the form <code>1..n</code> where <code>n</code> is the total number
+of tests run. This secures TAP compliance when needed. The call to <code>done</code>
+is not otherwise required. If you don&rsquo;t care about TAP compliance, neither does
+the library. If you pass the optional parameter to the method, it will check
+whether the number of tests you expected matches the number of actual tests.
+Thus, if can function like a traditional <code>plan</code> method. However, this method
+should always be called <em>last</em> in your tap file, unlike <code>plan</code> methods which
+normally start the test file.</p>
+
+<p>Another reason to use <code>done</code> is if you care about the exit status of the
+tests. Many continuous integration tools rely on tests signalling success or
+failure via their exit status. After <code>done</code> is called, the script will exit
+with a status of 0, indicating success, if all tests passed. If some tests
+failed, the script will exit with a status equal to the number of failed
+tests, indicating failure. A script will also exit with an error status if
+there is a mismatch between the actual number of tests run and the number
+passed to <code>done</code> as a parameter.</p></li>
+</ul>
+
+
+<h2>Varia</h2>
+
+<p>The module provides four informational functions that return strings. They
+should be self-explanatory.</p>
+
+<ul>
+<li><p><code>version() -- 2.3.0</code></p></li>
+<li><p><code>author() -- Peter Aronoff</code></p></li>
+<li><p><code>url() -- https://github.com/telemachus/tapered.git</code></p></li>
+<li><p><code>license() -- BSD 3-Clause</code></p></li>
+</ul>
+
+
+<h2>Credits</h2>
+
+<p>For the <code>same</code> method I took ideas and code from <a href="https://github.com/stevedonovan/Penlight">Penlight</a>, <a href="https://github.com/mirven/underscore.lua">Underscore</a>,
+<a href="https://github.com/Olivine-Labs/luassert">luassert</a>, and <a href="https://github.com/catwell/cwtest">cwtest</a>. I thank all the people who worked on those.</p>
+
+<p>Indirect inspirations include <a href="https://github.com/chneukirchen/knock">knock</a>, <a href="http://search.cpan.org/perldoc?Test::More">Test::More</a>, and <a href="https://github.com/sstephenson/bats">bats</a>—not so
+much for code as for ideas about testing and simplicity.</p>
+
+<p>Thanks in particular to <a href="https://twitter.com/pchapuis">Pierre Chapuis</a> for help with ideas and
+getting continuous integration for tapered.</p>
+
+<p>An anonymous email showed me that my setup and teardown methods had a logical
+flaw. As a result, I&rsquo;ve removed those methods. I appreciate the report.</p>
+
+<p>All the mistakes are mine. See <a href="changes.html">version history</a> for release details.</p>
