<h1>Introduction</h1>

<p>The reliability and robustness of SQLite is achieved in part
by thorough and careful testing.</p>

<p>As of [version 3.16.2] ([dateof:3.16.2]),
the SQLite library consists of approximately
<tcl>KB {$stat(coreSLOC)}</tcl> KSLOC of C code.
(KSLOC means thousands of "Source Lines Of Code" or, in other words,
lines of code excluding blank lines and comments.)
By comparison, the project has
<tcl>
hd_puts "[expr {int($stat(totalSLOC)/$stat(coreSLOC))}] times as much"
................................................................................
so that on a full test run millions of
separate tests are performed.
</p>
</li>

<li><p>
The <b>[TH3]</b> test harness is a set of proprietary tests, written in
C that provide 100% branch test coverage (and 100% MC/DC test coverage) to

the core SQLite library.  The TH3 tests are designed to run
on embedded and specialized platforms that would not easily support
TCL or other workstation services.  TH3 tests use only the published 
SQLite interfaces. TH3 consists of about
<tcl>MB {$stat(th3NByte)}</tcl> MB or <tcl>KB {$stat(th3SLOC)}</tcl> KSLOC
of C code implementing <tcl>N {$stat(th3NTest)}</tcl> distinct test cases.
TH3 tests are heavily parameterized, though, so a full-coverage test runs
