TiddlyWiki5 incorporates the Jasmine JavaScript testing framework (see http://pivotal.github.io/jasmine/). It allows the same tests to be run both in the browser and under Node.js.

! TiddlyWiki5 Testing Components

There are two main elements to the TiddlyWiki5 testing mechanism:

* The plugin `tiddlywiki/jasmine` that wraps Jasmine up into a plugin along with some glue code
* The TiddlyWiki5 edition `test` that contains the core test specifications and includes the Jasmine plugin

! Running the Tests in Node.js

To run the tests under Node.js just load up the `test` wiki:

```
node ./tiddlywiki.js \
	./editions/test \
```

! Running the Tests in the Browser

To generate a wiki containing the browser tests load up the `test` wiki and save it as an HTML file:

```
node ./tiddlywiki.js \
	./editions/test \
	--verbose \
	--rendertiddler $:/core/save/all $TW5_BUILD_OUTPUT/test.html text/plain \
```

Then, open the `test.html` file in the browser to see the test results. There is a prebuilt version of `test.html` at:
