Software defect indicator

<p>A Software Defect Indicator is a pattern that can be found in <a href="/facts/Source_code/o9J6Jv23">source code</a> that is strongly correlated with a <a href="/facts/Software_defect/I1uSXySv">software defect</a>, an error or omission in the source code of a computer program that may cause it to malfunction. When inspecting the source code of <a href="/facts/Computer_program/e38jH9N9">computer programs</a>, it is not always possible to identify defects directly, but there are often patterns, sometimes called <a href="/facts/Anti-pattern/BSSJC6os">anti-patterns</a>, indicating that defects are present.
</p><p>Some examples of Software Defect Indicators:
</p>
<ul><li>Disabled Code: Code has been written and the <a href="/facts/Programmer/WGTS1Jv9">programmer</a> has disabled it, or switched it off, without making it clear why it has been disabled, or when or whether it will be re-enabled.</li>
<li>Routine Too Complex: A program (method, module, routine, subroutine, procedure, or any named block of code) contains more than 10 binary terms in conditional statements.</li>
<li>Unused Variables: Unreferenced variables are a strong indicator for other errors.</li>
<li>Number of Distinct Committers: The amount of unique developers that have made contributions to a project's commit history. This is a process metric that is useful in indicating software defects. </li></ul>
