You'll find a number of FREE distributions of SQLite source code files here: http://www.sqlite.org/download.html The full distribution is the one called sqlite-3_6_23-tea.tar.gz (1.14 MiB) And, as you can see, it includes a test suite. The purpose of the test suite is /not/ to test SQLite itself because the authors have done that. It's to test your hardware, OS, compiler and linker to make sure that your own compilation of SQLite is sane on your particular platform. The only people who run the test suite in anger are those who are compiling for non-standard hardware (embedded platforms) who are rare, and those who think they've spotted a bug in SQLite who are even rarer. Many people who run SQLite are not really concerned about the inner workings of SQLite. They are dealing with a big and complicated set of source files themselves and they don't want one tiny piece of their program -- a database engine -- to look big and complicated in their development environment. For those people, SQLite makes the amalgamation package available: one file of C code and one header file, which is as simple as C gets. That's the one you were told to use for your programming: sqlite-amalgamation-3_6_23_1.zip (1.07 MiB) If you have no reason to be suspicious of SQLite because you use the same hardware and compiler as everyone else, the amalgamation files are the only ones you need, and that's the way almost everyone does it. So you have the test suite right there, for free, if you need it. The reason you were initially told about the amalgamation version is that almost nobody does. > I'm not talking about something that uses weeks of CPU time, gives 100% > branch > coverage and requires commerical licences to use.

That's the way SQLite splits it: the really big and complicated test suite is not a freebie (and is not mentioned on the above page). However, there's a smaller simpler and faster set of tests, still quite thorough, which you can get free as described above.
