+
+Compound tiddlers are a special type of tiddler that can store one or more payload tiddlers. The tiddlers within a compound tiddler are only accessible via special operations, typically with the TestCaseWidget.
+
+The compound tiddler format is extremely simple, and includes the notable flaw that it does not permit tiddlers that contain a plus sign (`+`) on a line by itself. It is not intended as a general purpose way of storing tiddler data.
+
+Compound tiddlers are identified by having their type field set to `text/vnd.tiddlywiki-multiple`.
+
+The content of a compound tiddler consists of a sequence of tiddlers separated by a plus sign (`+`) on a line by itself. Each tiddler uses the same format as [[.tid files|TiddlerFiles]].
+
+For example:
+
+```
+title: First
+tags: one two
+
+This is the first tiddler
++
+title: Second
+tags: three four
+
+This is the second tiddler
++
+title: third
+tags: five six
+
+This is the third tiddler
+```

+Test case tiddlers encapsulate one or more tiddlers that can be displayed as a [[test case|TestCaseWidget]]: an independent embedded wiki that can be used for testing or learning purposes.
+
+Test case tiddlers are formatted as CompoundTiddlers, allowing them to contain multiple tiddlers packed into one.
+
+Test case tiddlers have the following fields:
+
+|!Field |!Description |
+|<<.field type>> | Should be set to `text/vnd.tiddlywiki-multiple` |
+|<<.field tags>> | Test cases are tagged [[$:/tags/wiki-test-spec]]. Test cases that intentionally fail are tagged [[$:/tags/wiki-test-spec-failing]] |
+|<<.field description>> |Descriptive heading for the test, intended to make it easy to identify the test |
+|<<.field display-format>> |Optional, defaults to `wikitext`. Set to `plaintext` to cause the output to be rended as plain text |
+
+Test case tiddlers with the appropriate tag are shown in $:/ControlPanel
+
+Some payload tiddlers are set aside for special purposes:
+
+|!Tiddler |!Description |
+|''Narrative'' |Narrative description of the test, intended to explain the purpose and operation of the test |
+|''Output'' |The tiddler that produces the test output |

+!! Cache Busting
+
+There are a couple different ways of changing the names of files so that they will load when they change. One way is to use version numbers and have them somewhere in the file name when loading. You could have a subdirectory for every version, `v1/index.js` `v2/index.css` . You could also have the version in queries in the URLs, `index.js?v1` , `index.css?v2` .
+
+Another way is to change the name of the file, `index.v1.js` , `index.v2.css` . These ways are not as manageable because this can become very hard once you have a ton of files that are being changed.
+
+A more popular and manageable way is to keep hashes inside the file names. Hashes, if you don’t know, are fixed length character representations of any content and they are irreversible, meaning you can get the hash from the file but you can’t get the file from the hash. Hashes are perfect for this, because when a file changes its hash will change, so if we keep the hash inside the filename `index.[someHashHere].js` browsers will detect it and load it instead of an old file.

+The [[web server configuration parameter|WebServer Parameters]] ''use-browser-cache=yes'' activates 200 OK browser caching via the `Cache-Control` header and a smart a Etag header:
+
+* The server javascript creates an MD5 `hash` object.
+* Adds the data of the current `request:response` (for example: json text or an image binary) to the hash object.
+* Adds the current `headers` of the response to the hash object.
+* If the response data has an `encoding` value, adds the encoding to the hash object.
+* Calculates the final MD5 hash string as a `contentDigest` javascript variable, and saves it as an `Etag: "<<contentDigest>>"` header.
+
+If the incoming request contains a header named `if-none-match`, then the server will check the generated Etag against all values.
+
+If any `if-none-match` value DOES match the current Etag, the server will send a `304 NOT MODIFIED` response with the current response headers, instead of the data with a `200 OK` response.
+
+This saves bandwidth, as the client can be sure they have already received the exact data and has it in their current cache.
+
+If ''use-browser-cache=no'' (or any other value including null), then the server will return a `Cache-Control: no-store` header by default.
+
+If any customer server route module defines custom `Cache-Control` header behavior, then the server will pass that header through instead of the default.

+tags: Widgets
+title: TestCaseWidget
+type: text/vnd.tiddlywiki
+
+! Introduction
+
+The <<.wid testcase>> widget is designed to present interactive example test cases that are useful for learning and testing. It functions by creating an independent subwiki loaded with the specified payload tiddlers and then rendering a specified template from within the subwiki. The <<.wid testcase>> widget can optionally also be used to run and verify test results within the subwiki.
+
+This makes it possible to run independent tests that also serve as documentation examples.
+
+The <<.wid testcase>> widget can be used directly as documented below, but it is generally easier to create [[TestCaseTiddlers]]. These are special CompoundTiddlers that can contain multiple payload tiddlers making up a test case.
+
+!! Features
+
+Here is an example of a test case showing the default split view with the source tiddlers on the left and the tiddler titled `Output` rendered on the right.
+
+<<testcase "TestCases/TranscludeWidget/SimpleTransclusion">>
+
+Notice also that clicking on links within the output pane will switch to the tab containing that tiddler.
+
+The text of the payload tiddlers listed on the left are editable, with the results being immediately reflected in the preview pane on the right. However, if the <<.wid testcase>> widget is refreshed then the modifications are lost.
+
+The green tick at the top left of a test case indicates that a test has been set up and that it passes.
+
+If the test fails, a red cross is shown, and there is a display of the differences between the actual results and the expected results:
+
+<<testcase "TestCases/TestCaseWidget/FailingTest">>
+
+! Limitations
+
+The <<.wid testcase>> widget creates a lightweight TiddlyWiki environment that is a parasite of the main wiki. Because it is not a full, independent TiddlyWiki environment, there are some important limitations:
+
+* Output is rendered into a DIV, and so cannot be styled independently of the host wiki
+* Any changes to the wiki made interactively by the user are volatile, and are lost when the <<.wid testcase>> widget is refreshed
+* Startup actions are not supported
+* Only plugins available in the host wiki can be included in the test case
+
+If these limitations are a problem, the [[Innerwiki Plugin]] offers the ability to embed a fully independent subwiki via an `<iframe>` element, but without the testing related features of the <<.wid testcase>> widget.
+
+! Content and Attributes
+
+The content of the `<$testcase>` widget is not displayed but instead is scanned for <<.wlink DataWidget>> widgets that define the payload tiddlers to be included in the test case.
+
+|!Attribute |!Description |
+|<<.attr template>> |Optional title of the template used to display the test case (defaults to $:/core/ui/testcases/DefaultTemplate). Note that custom templates will need to be explicitly added to the payload |
+|<<.attr testOutput>> |Optional title of the tiddler whose output should be subject to testing (note that both <<.attr testOutput>> and  <<.attr testExpectedResult>> must be provided in order for testing to occur) |
+|<<.attr testExpectedResult>> |Optional title of the tiddler whose content is the expected result of rendering the output tiddler (note that both <<.attr testOutput>> and  <<.attr testExpectedResult>> must be provided in order for testing to occur)  |
+|<<.attr testActions>> |Optional title of the tiddler containing actions that should be executed before the test occurs |
+|<<.attr testHideIfPass>> |If set to "yes", hides the <<.wid testcase>> widget if the test passes |
+
+! Payload Tiddlers
+
+The payload tiddlers are the tiddler values that are loaded into the subwiki that is created to run the tests. They are created via <<.wlink DataWidget>> widgets within the body of the `<$testcase>` widget. The `$:/core` plugin is automatically included in the payload.
+
+! Testcase Templates
+
+The <<.attr template>> attribute defaults to $:/core/ui/testcases/DefaultTemplate
+
+The default test case template assigns special meanings to a number of payload tiddlers:
+
+|!Tiddler |!Description |
+|''Description'' |Descriptive heading for the test, intended to make it easy to identify the test |
+|''Narrative'' |Narrative description of the test, intended to explain the purpose and operation of the test |
+|''Output'' |The tiddler that produces the test output |
+|''~ExpectedResult'' |HTML of expected result of rendering the ''Output'' tiddler |
+
+The test case wiki will inherit variables that are visible to the <<.wid testcase>> widget itself. The default template uses several variables that can be set by the user:
+
+|!Variable |!Description |
+|<<.var linkTarget>> |Causes the test case description to be rendered as a link to the current tiddler |
+|<<.var displayFormat>> |Defaults to "wikitext", can also be "plaintext" to force plain text display |
+
+A custom template can be specified for special purposes. For example, the provided template $:/core/ui/testcases/RawJSONTemplate just displays the payload tiddlers in JSON, which can be used for debugging purposes.
+
+! Test Czase Template Variables
+
+The <<.wid testcase>> widget makes the following variables available within the rendered template:
