—dev:dgreftest [2016/05/26 19:31] (current) – created deva
Line 1: Line 1:
 +======DGRefTest======
 +It is located in test/dgreftest folder.
 +It is only compiled if configure was run with smf support (implicit in cli) and unittests.
  
 +
 +This is the output when run with no arguments:
 +<code>
 +$ ./dgreftest 
 +Usage: ./dgreftest testname drumkit midimap [seed]
 +</code>
 +
 +''testname'' is the //basename// used to create two files: //testname//.mid and //testname//.wav, ie. testname = "foo" will look for the files ''foo.mid'' and ''foo.wav''.
 +
 +Drumkit and midimap are the usual arguments as known from the drumgizmo command line interface.
 +
 +The //seed// is an integer used to seed the Random engines. It is optional, and will efault to 0 if omittted.
 +
 +=====Run test=====
 +To run the dgreftest on an existing set of files it is important to use the same drumkit, midimap and seed as was originally used.
 +
 +A couple of test can be downloaded here: [[http://www.aasimon.org/public/reftest]]
 +
 +They can be run with the following two commandlines:
 +<code>
 +$ ./dgreftest test-aasimonster /your/path/to/aasimonster/{aasimonster,midimap}.xml 42
 +$ ./dgreftest test-aasimonster2 /your/path/to/aasimonster2/{aasimonster,midimap}.xml 42
 +</code>
 +
 +At the end of the test a diff value is being printet. It is the difference sum of all samples in the output compared to the reference file. If it is 0 the test tells us that the code did not change compared to when the reference file was generated.
 +<code>
 +diff_samples: 0
 +</code>
 +
 +Be aware that a result not 0 is not nessecarily an error, it just signifies that //something// changed //somewhere// but it might have changed into something else that is also correct.
 +
 +If there is a change it is however important to put some thought into why there is a change and whether it is actually a good thing ;)
 +
 +=====Create test=====
 +To create a test, simply run the application only with the .mid file. This will make dgreftest create the .wav file.
