<h3>I'm trying to load my code with the URL |
| 17 |
|
|
<code>file:///C:/foo/bar/jscoverage.html?foo/bar.html</code> |
| 18 |
|

and I'm getting all kinds of JavaScript errors.</h3> |

Internet Explorer 6 seems to have problems with a <code>file:</code> URL |
| 22 |
|
|
that has a query string with a slash in it. |
| 23 |
|
|
</p> |
| 24 |
|
|
<p> |
| 25 |
|
|
As a workaround: |
| 26 |
|
|
</p> |
| 27 |
|
|
<ul class="list"> |
| 28 |
|
|
<li>Place your files on a web server instead of loading them from the file system. |
| 29 |
|
|
(<code>http:</code> URLs work fine.) |
| 30 |
|
|
<li>Do not use a query string; enter your URL in the "URL" field in the "Browser" tab. |
| 31 |
|
|
<li>Rearrange your directory structure so that <code>bar.html</code> |
| 32 |
|
|
ends up in the same directory as <code>jscoverage.html</code>; then |
| 33 |
|
|
you can use the URL |
| 34 |
|
|
<code>file:///C:/foo/bar/jscoverage.html?bar.html</code> |
| 35 |
|
|
with no slash in the query string. |
| 36 |
|
|
<li>Use a different browser. (IE 7 seems to work.) |
| 37 |
|
|
</ul> |

<h3>JSCoverage changes my cursor to a busy cursor, and it never changes back!</h3> |
| 40 |
|
|
|
| 41 |
|
|
<p> |
| 42 |
|
|
Certain browsers (<i>e. g</i>., Internet Explorer 6, Opera, Safari) have trouble changing |
| 43 |
|
|
the cursor. Try moving the mouse and your cursor should change back to normal. |

<h3>JSCoverage hangs sometimes when rendering the coverage report.</h3> |
| 51 |
|
|
|
| 52 |
|
|
<p> |
| 53 |
|
|
With Internet Explorer 6 (I think I see a pattern here), garbage collection can cause performance problems. |
| 54 |
|
|
(More information <a href="http://ajaxian.com/archives/garbage-collection-in-ie6">here</a>.) |

<h3>Can JSCoverage be used with <a href="http://www.jsunit.net/">JsUnit</a>?</h3> |
| 58 |
|
|
|
| 59 |
|
|
<p> |
| 60 |
|
|
It is necessary to run JSCoverage in <dfn>inverted mode</dfn>. You will have to |
| 61 |
|
|
modify JsUnit to launch JSCoverage. |
| 62 |
|
|
</p> |
| 63 |
|
|
|
| 64 |
|
|
<p> |
| 65 |
|
|
See the directory <code>doc/example-jsunit</code> for an example. It |
| 66 |
|
|
contains a copy of JsUnit version 2.2alpha11, with the file |
| 67 |
|
|
<code>jsunit/app/main-data.html</code> slightly modified to add a button |
| 68 |
|
|
which launches JSCoverage. It also contains a simple unit test file <code>test.html</code>. You |
| 69 |
|
|
can instrument this example as follows: |
| 70 |
|
|
</p> |
| 71 |
|
|
|
| 72 |
|
|
<pre> |
| 73 |
|
|
jscoverage --no-instrument=jsunit doc/example-jsunit doc/instrumented-jsunit |
| 74 |
|
|
</pre> |
| 75 |
|
|
|
| 76 |
|
|
<p> |
| 77 |
|
|
You can then run the <code>test.html</code> file in JsUnit's <code>jsunit/testRunner.html</code>. |
| 78 |
|
|
The simplest way to do this is probably to copy the contents of <code>doc/instrumented-jsunit</code> |
| 79 |
|
|
to the root of a web server and then access the URL |
| 80 |
|
|
</p> |
| 81 |
|
|
|
| 82 |
|
|
<pre> |
| 83 |
|
|
http://127.0.0.1/jsunit/testRunner.html?testPage=http://127.0.0.1/test.html&autorun=true |
| 84 |
|
|
</pre> |
| 85 |
|
|
|
| 86 |
|
|
<p> |
| 87 |
|
|
After the test suite has been run, click on the "Coverage report" button |
| 88 |
|
|
to get a coverage report. |
| 89 |
