JSCoverage is a tool that measures code coverage for |
16 |
|
|
JavaScript programs. |
17 |
siliconforks |
2 |
</p> |
18 |
|
|
<p> |
19 |
siliconforks |
76 |
<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 |
siliconforks |
217 |
for constructing comprehensive test suites (hence, it is often called |
22 |
siliconforks |
76 |
<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 |
siliconforks |
217 |
JSCoverage supports the complete language syntax described in the |
31 |
|
|
<cite>ECMAScript Language Specification</cite> (ECMA-262, 3rd edition). |
32 |
siliconforks |
2 |
JSCoverage works with any modern standards-compliant web browser - |
33 |
siliconforks |
506 |
including Internet Explorer (IE 6, 7, and 8), Firefox, |
34 |
siliconforks |
291 |
Opera, Safari, and Google Chrome - on Microsoft Windows and GNU/Linux. |

<h3><a name="20100923">September 23, 2010 - JSCoverage 0.5.1</a></h3> |
44 |
|
|
<p> |
45 |
|
|
JSCoverage 0.5.1 is available for <a href="http://siliconforks.com/jscoverage/download.html">download</a>. |
46 |

</p> |
47 |

<p> |

|
This release contains several bug fixes and improvements: |
49 |
|
|
</p> |
50 |
|
|
<ul class="list"> |
51 |
|
|
<li> |
52 |
|
|
Probably the largest change is in the documentation: the manual no |
53 |
|
|
longer recommends using <code>file:</code> URLs. |
54 |
|
|
It is recommended that an HTTP server be used instead. |
55 |
|
|
(See the <a href="manual.html">manual</a> for details.) |
56 |
|
|
The JSCoverage user interface now displays a warning when used with |
57 |
|
|
<code>file:</code> URLs. |
58 |
|
|
</li> |
59 |
|
|
<li> |
60 |
|
|
The <code>--verbose</code> option to <code>jscoverage</code> now |
61 |
|
|
produces better output. |
62 |
|
|
</li> |
63 |
|
|
<li> |
64 |
|
|
Report loading is now faster (thanks to Klaus). |
65 |
|
|
</li> |
66 |
|
|
<li> |
67 |
|
|
Some bugs involving augmented object prototypes were fixed. |
68 |
|
|
</li> |
69 |
|
|
<li> |
70 |
|
|
JavaScript instrumentation was improved to work better in non-browser |
71 |
|
|
environments. |
72 |
|
|
</li> |
73 |
|
|
<li> |
74 |
|
|
Some cases where permission errors were occurring in inverted mode were |
75 |
|
|
fixed (thanks to tn). |
76 |
|
|
</li> |
77 |
|
|
<li> |
78 |
|
|
Previously, if <code>jscoverage-server</code> was started with the |
79 |
|
|
option <code>--ip-address=<var>A</var></code>, where <var>A</var> was a |
80 |
|
|
specific IP address, it was impossible to shut it down with |
81 |
|
|
<code>jscoverage-server --shutdown</code>. |
82 |
|
|
This should be possible now by running |
83 |
|
|
<code>jscoverage-server --shutdown --ip-address=<var>A</var></code> |
84 |
|
|
from the same machine. |
85 |
|
|
</li> |
86 |
|
|
<li> |
87 |
|
|
The test suite has been made more robust. |
88 |
|

94 |
|
|
This week there will be a series of articles about using JSCoverage with various JavaScript testing frameworks. |

The <a href="http://blog.siliconforks.com/2010/04/26/jscoverage-scriptaculous/">first article</a> looks at using JSCoverage with the <a href="http://script.aculo.us">script.aculo.us</a> test suite. |

105 |
|
|
<ul class="list"> |
106 |

<li> |
107 |

A new mode of operation, called "window mode", allows you to run code in a new browser window (or tab). |

Code coverage statistics can now be generated for applications based on |
111 |
|
|
the Mozilla platform using the <code>--mozilla</code> option (thanks to |
112 |
|
|
Murali Nandigama for help creating this). |

The method used to calculate overall percentage code coverage for all |
116 |
|
|
files has changed. Previously, the calculation was done using an |
117 |
|
|
unweighted average: each file's percentage code coverage contributed |
118 |
|
|
equally to the total, regardless of the number of lines of code in the |
119 |
|
|
file. Now, the calculation is done using a weighted average. This |
120 |
|
|
fixes |
121 |
|
|
<a href="http://siliconforks.com/jscoverage/bugs/6">bug #6</a> (thanks to |
122 |

Liu Cougar). |

124 |

Contiguous lines in the "Missing" column are now grouped together (thanks to |

Liu Cougar). |

The "Source" tab is no longer empty when code being tested throws an |
130 |

uncaught exception |

Previously, certain uses of the <code>new</code> operator were |
135 |
|
|
instrumented incorrectly; this has now been fixed |
136 |
|
|
(thanks to Guillaume Lung). |

The <code>jscoverage-server</code> program now handles HTTP headers with |
144 |
|
|
empty values (thanks to Velo). |

415 |
</li> |
146 |

<li> |
147 |

The <code>jscoverage</code> program now refuses to instrument code which |
148 |
|
|
has already been instrumented (thanks to Velo). |
149 |
|
|
</li> |
150 |
|
|
<li> |
151 |
|
|
URLs containing spaces now work correctly (thanks to Igor Papkov). |
152 |
|
|
</li> |
153 |
|
|
<li> |
154 |
|
|
Previously, on Windows, the <code>jscoverage</code> program |
155 |
|
|
was unable to instrument a directory in a drive root; this has now been |
156 |
|
|
fixed. |
157 |
|
|
</li> |
158 |
|
|
<li> |
159 |
|
|
Encoded URLs are now handled better in the query string. |
160 |
|
|
</li> |
161 |
|
|
<li> |
162 |
|
|
A limitation of 65,535 lines per file and 65,535 characters per line has |
163 |
|
|
been removed. |
164 |
|
|
</li> |
165 |
|
|
<li> |
166 |
|
|

170 |
|
|
</li> |
171 |
|
|
<li> |
172 |
|
|
Some bugs in <code>jscoverage-server</code>'s handling of the "chunked" |
173 |
|
|
Transfer-Encoding have been fixed. |
174 |
|
|
</li> |
175 |
|
|
<li> |
176 |
|
|
Compilation under Cygwin now uses the <code>-mno-cygwin</code> flag. |
177 |
|
|
</li> |
178 |
|
|
<li> |
179 |
|
|
The wire format used for submitting coverage reports for storage by |
180 |
|
|
<code>jscoverage-server</code> has changed. (This change will not have |
181 |
|
|
any visible effects for most users; it will only be of interest to those |
182 |
|
|
who have written code which parses that format.) |
