@alalek , do you remember whether the changes in this file are necessary? It seems that some calib3d and color conversion tests fail due to this modification.

These changes are used to have reproducible initial RNG seed (independent and different for each test_case_idx of the legacy test system).

RNG seeds are changed by this modification, so some tests are started to fail. This is the question to the testing code and performed checks.

The PR have passed all checks now. Following is the list of changes:

  • (1) enabled 2-channel arrays in imgwarp tests (the main purpose of this PR) - this change caused some tests failure due to changed RNG state, so we...
  • (2) enabled RNG resetting for old-style (e.g. based on ArrayTest) tests to make them more stable
  • (3) increased test threshold in test_convhull.cpp (MinTriangle), test_color.cpp (Lab, Luv), test_homohraphy.cpp (max_diff)
  • (3) partially converted Calib3d_Homography.accuracy to new style (plain GTest) and cv::theRNG()

Maybe there are too many commits? I can squash them into 1, 2 or 3 according to categories above if needed - please let me know.

@mshabunin Please squash and rebase commits to enable GitHub Actions checks too (GHA fetch workflows from source branch only :\ ).

It should be good now - I've rebased and "fixed" one flaky test in video module.
