| The test program | |
| ---------------- | |
| We need a test program that: | |
| - can read a file with the test specs | |
| - construct a pipeline using the pipeline definition in the spec file | |
| (using gst_parse_launch ()) | |
| - add signals to elements in the pipeline | |
| - run the pipeline for a fixed (in time/number of iterations) period | |
| - record the fireing of the signals | |
| - compare the signals to the expected results. | |
| spec file contents: | |
| ------------------- | |
| tcN: name-of-the-tescase | |
| tcP: pipeline of the testcase in gst_parse_launch () syntax. | |
| tcS: id1, element, signalname (attach to signal in an element) | |
| tcS: id2, element, signalname | |
| ... | |
| tcI: the number of iterations on the top bin | |
| tcT: a timeout value in mSecs | |
| tcR: id1,1,id2,1,.. (the pattern of signals triggered) | |
| or | |
| tcR: id1==id2,... (denote an equal number of signals) | |
| /n | |
| signal trigger patterns | |
