15 JSCoverage is a tool that measures code coverage for
16 JavaScript programs.
17 </p>
18 <p>
19 <dfn>Code coverage</dfn> statistics show which lines of a program have
20 been executed (and which have been missed). This information is useful
21 for constructing comprehensive test suites (hence, it is often called
22 <dfn>test coverage</dfn>).
23 </p>
24 <p>
25 JSCoverage works by instrumenting the JavaScript code used in web
26 pages. Code coverage statistics are collected while the instrumented
27 JavaScript code is executed in a web browser.
28 </p>
29 <p>
30 JSCoverage supports the complete language syntax described in the
31 <cite>ECMAScript Language Specification</cite> (ECMA-262, 3rd edition).
32 JSCoverage works with any modern standards-compliant web browser -
33 including Internet Explorer (IE 6, 7, and 8), Firefox,
34 Opera, Safari, and Google Chrome - on Microsoft Windows and GNU/Linux.
35 </p>

45 If you would like to see some case studies showing how to use JSCoverage in practice, take a look at the new <a href="http://blog.siliconforks.com/">blog</a>.
46 This week there will be a series of articles about using JSCoverage with various JavaScript testing frameworks.
47 The first article looks at using JSCoverage with the <a href="http://script.aculo.us">script.aculo.us</a> test suite.

50 <h3><a name="20100424">April 24, 2010 - JSCoverage 0.5</a></h3>
51 <p>
52 JSCoverage 0.5 is available for <a href="http://siliconforks.com/jscoverage/download.html">download</a>.
53 </p>
54 <p>
55 This release contains a number of new features and bug fixes:
56 </p>
57 <ul class="list">
58 <li>
59 A new mode of operation, called "window mode", allows you to run code in a new browser window (or tab).
60 </li>
61 <li>
62 Code coverage statistics can now be generated for applications based on
63 the Mozilla platform using the <code>--mozilla</code> option (thanks to
64 Murali Nandigama for help creating this).
65 </li>
66 <li>
67 The method used to calculate overall percentage code coverage for all
68 files has changed. Previously, the calculation was done using an
69 unweighted average: each file's percentage code coverage contributed
70 equally to the total, regardless of the number of lines of code in the
71 file. Now, the calculation is done using a weighted average. This
72 fixes
73 <a href="http://siliconforks.com/jscoverage/bugs/6">bug #6</a> (thanks to
74 Liu Cougar).
75 </li>
76 <li>
77 Contiguous lines in the "Missing" column are now grouped together (thanks to
78 Liu Cougar).
79 </li>
80 <li>
81 The "Source" tab is no longer empty when code being tested throws an
82 uncaught exception
83 (fixing <a href="http://siliconforks.com/jscoverage/bugs/5">bug #5</a>)
84 </li>
85 <li>
86 Previously, certain uses of the <code>new</code> operator were
87 instrumented incorrectly; this has now been fixed
88 (thanks to Guillaume Lung).
89 </li>
90 <li>
91 The <code>jscoverage-server</code> program now allows more characters in
92 URLs (thanks to Guillaume Lung).
93 </li>
94 <li>
95 The <code>jscoverage-server</code> program now handles HTTP headers with
96 empty values (thanks to Velo).
97 </li>
98 <li>
99 The <code>jscoverage</code> program now refuses to instrument code which
100 has already been instrumented (thanks to Velo).
101 </li>
102 <li>
103 URLs containing spaces now work correctly (thanks to Igor Papkov).
104 </li>
105 <li>
106 Previously, on Windows, the <code>jscoverage</code> program
107 was unable to instrument a directory in a drive root; this has now been
108 fixed.
109 </li>
110 <li>
111 Encoded URLs are now handled better in the query string.
112 </li>
113 <li>
114 A limitation of 65,535 lines per file and 65,535 characters per line has
115 been removed.
116 </li>
117 <li>
118 Floating-point numbers are now handled with improved precision.
119 </li>
120 <li>
121 The <code>jscoverage-server</code> program can no longer bind to the same port multiple times on Windows.
122 </li>
123 <li>
124 Some bugs in <code>jscoverage-server</code>'s handling of the "chunked"
125 Transfer-Encoding have been fixed.
126 </li>
127 <li>
128 Compilation under Cygwin now uses the <code>-mno-cygwin</code> flag.
129 </li>
130 <li>
131 The wire format used for submitting coverage reports for storage by
132 <code>jscoverage-server</code> has changed. (This change will not have
133 any visible effects for most users; it will only be of interest to those
134 who have written code which parses that format.)
