-# Release Notes
-
-## 2024.05.21
-
-### Features
-
-### Bug fixes
-
-### Enhancements
-
--   `py-editor` run buttons now display a spinner when disabled, which occurs when the editor is running code.
-
-## 2023.05.01
-
-### Features
-
--   Added the `xterm` attribute to `py-config`. When set to `True` or `xterm`, an (output-only) [xterm.js](http://xtermjs.org/) terminal will be used in place of the default py-terminal.
--   The default version of Pyodide is now `0.23.2`. See the [Pyodide Changelog](https://pyodide.org/en/stable/project/changelog.html#version-0-23-2) for a detailed list of changes.
--   Added the `@when` decorator for attaching Python functions as event handlers
--   The `py-mount` attribute on HTML elements has been deprecated, and will be removed in a future release.
-
-#### Runtime py- attributes
-
--   Added logic to react to `py-*` attributes changes, removal, `py-*` attributes added to already live nodes but also `py-*` attributes added or defined via injected nodes (either appended or via `innerHTML` operations). ([#1435](https://github.com/pyscript/pyscript/pull/1435))
-
-#### <script type="py">
-
--   Added the ability to optionally use `<script type="py">`, `<script type="pyscript">` or `<script type="py-script">` instead of a `<py-script>` custom element, in order to tackle cases where the content of the `<py-script>` tag, inevitably parsed by browsers, could accidentally contain _HTML_ able to break the surrounding page layout. ([#1396](https://github.com/pyscript/pyscript/pull/1396))
-
-#### &lt;py-terminal&gt;
-
--   Added a `docked` field and attribute for the `<py-terminal>` custom element, enabled by default when the terminal is in `auto` mode, and able to dock the terminal at the bottom of the page with auto scroll on new code execution.
-
-#### &lt;py-script&gt;
-
--   Restored the `output` attribute of `py-script` tags to route `sys.stdout` to a DOM element with the given ID. ([#1063](https://github.com/pyscript/pyscript/pull/1063))
--   Added a `stderr` attribute of `py-script` tags to route `sys.stderr` to a DOM element with the given ID. ([#1063](https://github.com/pyscript/pyscript/pull/1063))
-
-#### &lt;py-repl&gt;
-
--   The `output` attribute of `py-repl` tags now specifies the id of the DOM element that `sys.stdout`, `sys.stderr`, and the results of a REPL execution are written to. It no longer affects the location of calls to `display()`
--   Added a `stderr` attribute of `py-repl` tags to route `sys.stderr` to a DOM element with the given ID. ([#1106](https://github.com/pyscript/pyscript/pull/1106))
--   Resored the `output-mode` attribute of `py-repl` tags. If `output-mode` == 'append', the DOM element where output is printed is _not_ cleared before writing new results.
--   Load code from the attribute src of py-repl and preload it into the corresponding py-repl tag by use the attribute `str` in your `py-repl` tag([#1292](https://github.com/pyscript/pyscript/pull/1292))
--   &lt;py-repl&gt; elements now have a `getPySrc()` method, which returns the code inside the REPL as a string.([#1516](https://github.com/pyscript/pyscript/pull/1292))
-
-#### Plugins
-
--   Plugins may now implement the `beforePyReplExec()` and `afterPyReplExec()` hooks, which are called immediately before and after code in a `py-repl` tag is executed. ([#1106](https://github.com/pyscript/pyscript/pull/1106))
-
-#### Web worker support
-
--   introduced the new experimental `execution_thread` config option: if you set `execution_thread = "worker"`, the python interpreter runs inside a web worker
--   worker support is still **very** experimental: not everything works, use it at your own risk
-
-### Bug fixes
-
--   Fixes [#1280](https://github.com/pyscript/pyscript/issues/1280), which describes the errors on the PyRepl tests related to having auto-gen tags that shouldn't be there.
-
-### Enhancements
-
--   Py-REPL tests now run on both osx and non osx OSs
--   migrated from _rollup_ to _esbuild_ to create artifacts
--   updated `@codemirror` dependency to its latest
-

--   Add docs for event handlers
-
-## 2023.03.1
-
-### Features
-
-### Bug fixes
-
--   Fixed an issue where `pyscript` would not be available when using the minified version of PyScript. ([#1054](https://github.com/pyscript/pyscript/pull/1054))
--   Fixed missing closing tag when rendering an image with `display`. ([#1058](https://github.com/pyscript/pyscript/pull/1058))
--   Fixed a bug where Python plugins methods were being executed twice. ([#1064](https://github.com/pyscript/pyscript/pull/1064))
-
-### Enhancements
-
--   When adding a `py-` attribute to an element but didn't added an `id` attribute, PyScript will now generate a random ID for the element instead of throwing an error which caused the splash screen to not shutdown. ([#1122](https://github.com/pyscript/pyscript/pull/1122))
--   You can now disable the splashscreen by setting `enabled = false` in your `py-config` under the `[splashscreen]` configuration section. ([#1138](https://github.com/pyscript/pyscript/pull/1138))
-
-### Documentation
-
--   Fixed 'Direct usage of document is deprecated' warning in the getting started guide. ([#1052](https://github.com/pyscript/pyscript/pull/1052))
--   Added reference documentation for the `py-splashscreen` plugin ([#1138](https://github.com/pyscript/pyscript/pull/1138))
--   Adds doc for installing tests ([#1156](https://github.com/pyscript/pyscript/pull/1156))
--   Adds docs for custom Pyscript attributes (`py-*`) that allow you to add event listeners to an element ([#1125](https://github.com/pyscript/pyscript/pull/1125))
-
-### Deprecations and Removals
-
--   The py-config `runtimes` to specify an interpreter has been deprecated. The `interpreters` config should be used instead. ([#1082](https://github.com/pyscript/pyscript/pull/1082))
--   The attributes `pys-onClick` and `pys-onKeyDown` have been deprecated, but the warning was only shown in the console. An alert banner will now be shown on the page if the attributes are used. They will be removed in the next release. ([#1084](https://github.com/pyscript/pyscript/pull/1084))
--   The pyscript elements `py-button`, `py-inputbox`, `py-box` and `py-title` have now completed their deprecation cycle and have been removed. ([#1084](https://github.com/pyscript/pyscript/pull/1084))
--   The attributes `pys-onClick` and `pys-onKeyDown` have been removed. Use `py-click` and `py-keydown` instead ([#1361](https://github.com/pyscript/pyscript/pull/1361))

-A lot of problems related to `make setup` are related to node and npm being outdated. Once npm and node are updated, `make setup` should work. You can follow the steps on the [npm documentation](https://docs.npmjs.com/try-the-latest-stable-version-of-npm) to update npm (the update command for Linux should work for Mac as well). Once npm has been updated you can continue to the instructions to update node below.

-To update Node run the following commands in order (Most likely you'll be prompted for your user password, this is normal):
-
-```
-sudo npm cache clean -f
-sudo npm install -g n

 the following command:
 
 ```
-make test-integration
+make test
 ```
 
+(This essentially runs the `npm run test:integration` command in the right place. This is defined in PyScript's `package.json` file.)
+
+Tests are found in the `tests` directory. These are organised into three locations:
+
+1. `python` - the Python based test suite to exercise Python code **within** PyScript.
+2. `javascript` - JavaScript tests to exercise PyScript itself, in the browser.
+3. `manual` - containing tests to run manually in a browser, due to the complex nature of the tests.
+
+We use [Playwright](https://playwright.dev/) to automate the running of the Python and JavaScript test suites. We use [uPyTest](https://github.com/ntoll/upytest) as a test framework for the Python test suite. uPyTest is a "PyTest inspired" framework for running tests in the browser on both MicroPython and Pyodide.
+
+The automated (Playwright) tests are specified in the `tests/integration.spec.js` file.

 ## `pyscript` python package
 
 The `pyscript` package available in _Python_ lives in the folder `src/stdlib/pyscript/`.

+# PyScript Test Suite
+
+There are three aspects to our test suite. These are reflected in the layout of
+the test directory:
+
+1. `python` - contains the Python based test suite to exercise Python code
+   **within** PyScript. These tests are run four differeng ways to ensure all
+   combination of MicroPython/Pyodide and main thread/worker contexts are
+   checked.
+2. `javascript` - contains JavaScript tests to exercise PyScript _itself_, in
+   the browser.
+3. `manual` - contains tests to run manually in a browser, due to the complex
+   nature of the tests.
+
+We use [Playwright](https://playwright.dev/) to automate the running of the
+Python and JavaScript test suites. We use
+[uPyTest](https://github.com/ntoll/upytest) as a test framework for the Python
+test suite. uPyTest is a "PyTest inspired" framework for running tests in the
+browser on both MicroPython and Pyodide.
+
+The automated (Playwright) tests are specified in the `integration.spec.js`
+file in this directory.
+
+All automatic tests live in either the `python` or `javascript` folders. All
+the tests in these folder are run by CI or locally run by `make test` in the
+root of this project. Alternatively, run `npm run test:integration` in the
+PyScript source directory.
+
+Similarly, some tests can only be run manually (due to their nature or
+underlying complexity). These are in the `manual` directory and are in the form
+of separate directories (each containing an `index.html`) or individual `*.html`
+files to which you point your browser. Each separate test may exercise
+JavaScript or Python code (or both), and the context for each separate test is
+kept carefully isolated.
+
+Some rules of thumb:
+
+* We don't test upstream projects: we assume they have their own test suites,
+  and if we find bugs, we file an issue upstream with an example of how to
+  recreate the problem.
+* We don't test browser functionality, we just have to trust that browsers work
+  as advertised. Once again, if we find an issue, we report upstream.
+* All test cases should include commentary describing the **intent** and
+  context of the test.
+* Tests in Python use [uPyTest](https://github.com/ntoll/upytest) (see the
+  README for documentation), an "inspired by PyTest" test framework that works
+  with both MicroPython and Pyodide in the browser. This means that all
+  Python tests should work with both interpreters.
+* Tests in JavaScript... (Andrea to explain). ;-)
