+# Testing
+
+It‘s critical that changes you introduce do not cause regressions, i.e., that
+Tidy’s output remains consistent with the introduction of your changes, except
+for very specific circumstances.
+
+Additionally, changes that you introduce to Tidy must usually be accompanied by
+one or more test cases demonstrating the new feature or changed behavior.
+
+Both of these concerns can be addressed with the Tidy repository’s automated
+regression testing features, which are enabled by Github Actions. Any pull
+request you make will automatically test your PR against the existing set of
+test cases, and any failures are prima facie grounds for rejecting the PR. 
+
+You _must_ test your changes locally using the tools and test cases provided in
+the `regression_testing/` directory prior to submitting a PR, including adding
+test cases to this directory as needed.
+
+
+## Changes to Existing Output
+
+If your changes affect existing output, it’s critical to understand _why_, and
+if necessary, regenerate the `-expects` files so that the regression testing
+tool will pass with your new changes. These `-expects` changes, of course,
+become part of your Pull Request, and will be subject to review and conversation
+in the Pull Request thread.
+
+If you do cause such regressions, please be prepared to defend why they are
+needed.
+
+## New Tests
+
+If you’re adding new features to Tidy, code reviewers need to be able to see the
+intended effect of your changes via some type of demonstration. As such, please
+write at least one test case in `github-cases` and put the expected results in
+`github-expects`. These also constitute a part of your Pull Request, and more
+importantly, will become part of the standard regression testing suite once the
+PR is merged.
+
+Try to keep your test case(s) as succint as possible, and do try to put some HTML
+comments in the file explaining the purpose of the test case, and if applicable,
+the Github issue and/or PR number.
+
+Note that the files generated in `github-results` for your new test cases are
+suitable for use in `github-expects` when you are satisfied with the results.
+
+A sample `case-123a@0.html` might represent issue #123, test **a** in a series
+of multiple tests for this issue number, expecting Tidy exit code 0, and might
+look something like this:
+
+```
+<!DOCTYPE html>
+<html>
+<!--
+This test case represents HTML Tidy issue #123, and demonstrates
+the use of new feature #xxx. Tidy should exit with status code 0.
+The reason this change is needed is because WHATWG suddently
+determined that a standards change #yyyy impacts us because of zzz.
+ -->
+<head>
+<title>Case #123a</title>

+<p>The quick brown fox jumps over the lazy dog.<//p>
+<body>

+Tidy Regression Testing Specification
+=====================================
+
+Background
+----------
+HTML Tidy uses regression testing as its main means of quality control when 
+implementing new features and fixing bugs. HTML Tidy has been in constant 
+development since before unit testing and automated testing were in wide use,
+and has proven effective in guiding the development of Tidy.
+
+This repository is the regression testing tool used by Tidy for both 
+continuous integration, and for development work, and consists for test 
+cases split into multiple set sets, as well as tools for automating testing.
+
+Testing consists of automatically running some version (of your choice) of HTML 
+Tidy on various operating systems and architectures against the suite of 
+test cases, and comparing the Tidy and report output against known, “good” 
+versions thereof.
+
+This testing process ensures that:
+
+- No regressions occur as a result of the changes you make to HTML Tidy. 
+  Everything that has passed in the past should continue to pass, regardless 
+  of your changes. Changing test expectations for existing test cases must 
+  result in a discussion on the pull request discussion thread, otherwise 
+  regressions are _prima facie_ cause for rejecting your pull request.
+
+- Although touted as a “regression test,” code changes should also be 
+  furnished with a test case that demonstrates the issue being corrected or 
+  the feature being added. Logically you are already informally using one or 
+  most test cases during your development of the patch; this simply 
+  formalizes the requirement for HTML Tidy, and makes it much easier for the 
+  maintainers to understand the impact of your proposed change.
+
+Additionally, when introducing new features or fixing bugs,
+new test cases should be written to demonstrate that the fix works against 
+the test case.
+
+
+About the Test Tool (test.rb)
+-----------------------------
+The `test.rb` tool replaces the previous Windows shell and Bash testing 
+scripts. This start-from-scratch approach is intended to provide a single 
+script that’s platform agnostic, for the primary purpose of enabling 
+automated testing, but with strong support for use as a manual tool during 
+HTML Tidy development.
+
+Ruby was chosen as the scripting language of choice because it is available 
+on every platform, is easy to read (even if you're not a Ruby programmer), 
+and is supported by the major continuous integration testing providers, such 
+as Github.
+
+We recognize that some developers have scripting environment preferences, 
+and as such, please feel free write wrappers around `test.rb` as needed in 
+order to suit your prefences. If additional CLI API is needed to enable your 
+scripting environment wrapper, please feel free to request such.
+
+
+Building Tidy, and Tidy Versions
+--------------------------------
+The testing tool works by executing `tidy` (or `tidy.exe`, referred to only 
+as `tidy` continuing) on your platform. Naturally, you don’t want to conduct 
+testing using the normal, installed version of `tidy`, but rather version(s)
+that you’ve built for testing.
+
+By default, the `tidy` used will be in the standard build folder of the 
+`tidy-html5` directory that is a sibling to this `tidy-html5-tests` 
+directory. The complete relative path from `test.rb`, then, is:
+
+```
+../tidy-html5/build/cmake/tidy[.exe]
+```
+
+This makes it convenient when performing testing on both repositories when 
+they’re checked out. However you can also specify another build of HTML Tidy 
+as an optional argument, too.
+
+
+Static Build Considerations
+---------------------------
+By default, HTML Tidy is built as a console application statically linked to 
+LibTidy. Although the option to link against a dylib or dll exist when 
+building, it’s suggested that you no longer do so, because you might put 
+yourself into a situation where you’re testing multiple command line 
+executables that are all linked to the same dynamic library!
+
+Although not formally deprecated, you should consider dynamic linking 
+deprecated and treat it that way. In a world where entire Java Runtime 
+Environments are shipped _per program_, the benefits of dynamic linking no 
+longer exist on any modern computer or operating system. In some cases, 
+modern security hardening even prevents dynamic linking, and we’re likely to 
+see such restrictions become more common in the future.
+
+
+Running Test Tests
+------------------
+
+### Preparing the Environment
+
+Assuming that you have a working Ruby interpretor, version 2.7 or so, upon 
+`CD`-ing into the `tidy-html5-test` directory, you should execute `bundle 
+install`, which ensures that any dependencies that your environment doesn’t 
+already have will be downloaded.
+
+### Executing the Program
+
+In Windows shell and powershell, simply typing
+
+~~~
+test 
+~~~
+
+will run the tool. Usually. Probably. If not, try `ruby test.rb` in case 
+your environment is not configured to work directly.
+
+Unix and Unix-like operating systems (including WSL and other Unix-like 
+environments for Windows) can run the program like such:
+
+~~~
+test.rb
+~~~ 
+
+### Testing
+When used without any arguments, help will be provided. In general, though, 
+you can do the following:
+
+| Command                        | Effect                            |
+|--------------------------------|-----------------------------------|
+| `./test.rb test`               | Tests all cases in all test sets. |
+| `./test.rb only <setname>`     | Tests only in the given test set. |
+| `./test.rb case <case_number>` | Tests only on a single case.      |
+
+
+Input Specification
+-------------------
+
+### Test Sets
+
+“Test sets” are groups of individual tests that are thematically related,
+such as accessibility checks, XML-specific tests, historical tests, etc.
+Each set of cases consists of directories and a text file within the `cases/`
+directory. Each test set shall consist of the following directories/files, where
+`setname` indicates the name of the testing set, e.g., `testbase` (our default
+set of case files).
+
+- `setname/`, which contains the HTML files to tidy, and an optional
+  configuration file for each case.
+
+  - Test files shall have the format `case-basename@n<.html|.xml|.xhtml>`, 
+    where `nnn` represents the test case name, and the `@n` metadata 
+    represents the required shell exit status code that HTML Tidy should 
+    produce after running the test case. The case name cannot contain 
+    hyphens or the `@` symbol, and should represent something meaningful 
+    such a a Github issue number.
+
+  - Optional Tidy configuration files shall be named `case-basename.conf`.
+
+  - In the absense of a configuration file, the file `config_default.conf` in
+    each directory will be used instead.
+
+  - `README<.txt|.md>`, which describes the test set.
+
+- `setname-expects/`, which contains the expected output from HTML Tidy.
+  - Files in the format `case-nnn<.html|.xml|.xhtml>` represent the expected 
+    HTML file as generated by Tidy.
+  - Files in the format `case-nnn.txt` represent the expected warning/error
+    output from Tidy.
+      
+#### Example
+
+```
+cases/
+   testbase/
+      config_default.cong
+      case-427821.html
+      case-427821.conf
+   testbase-expects/
+      case-427821.html
+      case-427821.txt
+```
+
+
+Output Specification
+--------------------
+
+The output specification is written such that it makes it trivial to easily
+`diff` a `setname-expects` directory with the output of a test in order
+to check for differences.
+
+Test results consist of Tidy's HTML output and Tidy's warning/error output.
+
+Each set of results consists of directories within the `cases/` directory.
+
+- `setname-results` contains Tidy's HTML and warning/error output.
+  - Files in the format `case-nnn.html` are the HTML file generated by Tidy.
+  - Files in the format `case-nnn.txt` are the warning/error output from Tidy.
+
+### Example
+
+~~~
+cases/
+   testbase-results/
+      case-427821.html
+      case-427821.txt
+~~~

+About this test suite:
+======================
+
+These files ensure that Tidy is presenting the correct accessibility information
+when used with Tidy’s various levels of accessibility checking.
+
+The original accessibility test script looked for a single line of output
+present in Tidy's error output. Current treatment as a standard regression
+test accomplishes the same result, in that testing the entire error output is
+a superset of testing only the desired output anyway.
