15
16 <h3>Can JSCoverage be used with <a href="http://www.jsunit.net/">JsUnit</a>?</h3>
17
18 <p>
19 It is necessary to run JSCoverage in <dfn>inverted mode</dfn>. You will have to
20 modify JsUnit to launch JSCoverage.
21 </p>
22
23 <p>
24 See the directory <code>doc/example-jsunit</code> for an example. It
25 contains a copy of JsUnit version 2.2alpha11, with the file
26 <code>jsunit/app/main-data.html</code> slightly modified to add a button
27 which launches JSCoverage. It also contains a simple unit test file <code>test.html</code>. You
28 can instrument this example as follows:
29 </p>
30
31 <pre>
32 jscoverage --no-instrument=jsunit doc/example-jsunit doc/instrumented-jsunit
33 </pre>
34
35 <p>
36 You can then run the <code>test.html</code> file in JsUnit's <code>jsunit/testRunner.html</code>.
37 The simplest way to do this is probably to copy the contents of <code>doc/instrumented-jsunit</code>
38 to the root of a web server and then access
39 <a href="http://127.0.0.1/jsunit/testRunner.html?testPage=http://127.0.0.1/test.html&amp;autorun=true">this URL</a>.
40 </p>
41
42 <h3>I'm trying to load my code with the URL
43 <code>file:///C:/foo/bar/jscoverage.html?foo/bar.html</code>
44 and I'm getting all kinds of JavaScript errors.</h3>
45
46 <p>
47 Internet Explorer 6 seems to have problems with a <code>file:</code> URL
48 that has a query string with a slash in it.
49 </p>
50 <p>
51 As a workaround:
52 </p>
53 <ul class="list">
54 <li>Place your files on a web server instead of loading them from the file system.
55 (<code>http:</code> URLs work fine.)
56 <li>Do not use a query string; enter your URL in the "URL" field in the "Browser" tab.
57 <li>Rearrange your directory structure so that <code>bar.html</code>
58 ends up in the same directory as <code>jscoverage.html</code>; then
59 you can use the URL
60 <code>file:///C:/foo/bar/jscoverage.html?bar.html</code>
61 with no slash in the query string.
62 <li>Use a different browser. (IE 7 seems to work.)
63 </ul>
64
65 <h3>JSCoverage changes my cursor to a busy cursor, and it never changes back!</h3>
66
67 <p>
68 Certain browsers (<i>e. g</i>., Internet Explorer 6, Opera, Safari) have trouble changing
69 the cursor. Try moving the mouse and your cursor should change back to normal.
70 </p>
71
72 <p>
73 See the discussion <a href="http://groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/631908bd63241136/783c307480f95d8c">here</a> for more information.
74 </p>
75
76 <h3>JSCoverage hangs sometimes when rendering the coverage report.</h3>
77
78 <p>
79 With Internet Explorer 6 (I think I see a pattern here), garbage collection can cause performance problems.
80 (More information <a href="http://ajaxian.com/archives/garbage-collection-in-ie6">here</a>.)
