In order to measure the code coverage of a page on <code>http://example.com/</code>, |

you must run <code>jscoverage</code> to create a <code>jscoverage.html</code> file on the |
| 21 |
|
<code>example.com</code> server. You cannot use <code>http://example.org/jscoverage.html</code> |
| 22 |
|
to measure the code coverage of a page located on <code>http://example.com/</code>. |

|
|
can instrument this example as follows: |

|
|
| 31 |
<pre> |
<p> |

jscoverage --no-instrument=jsunit doc/example-jsunit doc/instrumented-jsunit |
(In fact, the current version of JSCoverage is slightly more restrictive |
| 33 |

than this: it requires that the JavaScript being measured reside under the |
| 34 |
|
same <strong>directory</strong> as the <code>jscoverage.html</code> file.) |
| 35 |
<p> |
</p> |
|
You can then run the <code>test.html</code> file in JsUnit's <code>jsunit/testRunner.html</code>. |
|
|
The simplest way to do this is probably to copy the contents of <code>doc/instrumented-jsunit</code> |
|
|
to the root of a web server and then access |
