-Asset Importer Lib Regression Test Suite
-========================================
-
-1) How does it work?
----------------------------------------------------------------------------------
-run.py checks all model in the <root>/test/models* folders and compares the result
-against a regression database provided with assimp (db.zip). A few failures
-are totally fine (see sections 7+). You need to worry if a huge
-majority of all files in a particular format (or post-processing configuration)
-fails as this might be a sign of a recent regression in assimp's codebase or
-gross incompatibility with your system or compiler.
-
-2) What do I need?
----------------------------------------------------------------------------------
- - You need Python installed (2.7+, 3.x). On Windows, run the scripts using "py".
- - You need to build the assimp command line tool (ASSIMP_BUILD_ASSIMP_TOOLS
-   CMake build flag). Both run.py and gen_db.py take the full path to the binary
-   as first command line parameter.
-
-3) How to add more test files?
----------------------------------------------------------------------------------
-Use the following procedure:
- - Verify the correctness of your assimp build - run the regression suite.
-   DO NOT continue if more tests fail than usual.
- - Add your additional test files to <root>/test/models/<fileformat>, where
-   <fileformat> is the file type (typically the file extension).
- - If you test file does not meet the BSD license requirements, add it to
-   <root>/test/models-nonbsd/<fileformat> so people know to be careful with it.
- - Rebuild the regression database:
-   "gen_db.py <binary> -ixyz" where .xyz is the file extension of the new file.
- - Run the regression suite again. There should be no new failures and the new
-   file should not be among the failures.
- - Include the db.zip file with your Pull Request. Travis CI enforces a passing
-   regression suite (with offenders whitelisted as a last resort).
-
-4) I made a change/fix/patch to a loader, how to update the database?
----------------------------------------------------------------------------------
- - Rebuild the regression database using "gen_db.py <binary> -ixyz"
-   where .xyz is the file extension for which the loader was patched.
- - Run the regression suite again. There should be no new failures and the new
-   file should not be among the failures.
- - Include the db.zip file with your Pull Request. Travis CI enforces a passing
-   regression suite (with offenders whitelisted as a last resort).
-
-5) How to add my whole model repository to the database?
----------------------------------------------------------------------------------
-
-Edit the reg_settings.py file and add the path to your repository to
-<<model_directories>>. Then, rebuild the database.
-
-6) So what is actually tested?
----------------------------------------------------------------------------------
-The regression database includes mini dumps of the aiScene data structure, i.e.
-the scene hierarchy plus the sizes of all data arrays MUST match. Floating-point
-data buffers, such as vertex positions are handled less strictly: min, max and
-average values are stored with low precision. This takes hardware- or
-compiler-specific differences in floating-point computations into account.
-Generally, almost all significant regressions will be detected while the
-number of false positives is relatively low.
-
-7) The test suite fails, what do do?
----------------------------------------------------------------------------------
-Get back to <root>/test/results and look at regression_suite_failures.txt.
-It contains a list of all files which failed the test. Failing dumps are copied to
-<root>/test/results/tmp. Both an EXPECTED and an ACTUAL file is produced per test.
-The output of "assimp cmpdump" is written to regressions_suite_output.txt. Grep
-for the file name in question and locate the log for the failed comparison. It
-contains a full trace of which scene elements have been compared before, which
-makes it reasonably easy to locate the offending field.
-
-8) fp:fast vs fp:precise fails the test suite (same for gcc equivalents)
----------------------------------------------------------------------------------
-As mentioned above, floating-point inaccuracies between differently optimized
-builds are not considered regressions and all float comparisons done by the test
-suite involve an epsilon to accommodate. However compiler settings that allow
-compilers to perform non-IEEE754 compliant optimizations can cause arbitrary
-failures in the test suite. Even if the compiler is configured to be IEE754
-comformant, there is lots of code in assimp that leaves the compiler a choice
-and different compilers make different choices (for example the precision of
-float intermediaries is implementation-specified).
