Test your skill to find the best move from the given test position where the player from the test sets fails to find. It generates a summary table with your selected move, the game move and the engine move. The test sets in json format can be found under the data folder.
You can also generate test positions with the use of test_generator.py which can be found in this repository. You need the stockfish engine to analyze the positions where the test_generator saves interesting positions in json format. There is also a stockfish 15 compiled for modern hardware under the engine folder.
Take a pgn file from the week in chess for example and generate test positions. It is better if the players have WhiteElo and BlackElo in the PGN because Position-Trainer can filter rating range and you can train on positions from those players with that filtered rating.

Download the json training file inside the data folder or from here. It is a test file that is needed for training.

Use the test_generator.py program to generate test positions. The output is in json format that can be used by Position-Trainer.
You need to install python chess with:
pip install chess
Run from the command line
python test_generator.py --pgn-file ./pgn/stlbli22_4games.pgn --engine-file ./engine/sf15.exe --engine-hash-mb 128 --output-file mytest.json --movetime 1000
The rate is based on the formula.
def score_proba(score_cp):
K = 6
score_p = score_cp/100
return 1 / (1 + 10 **(-score_p/K))fmvn is fullmove number
hmvc is half-move clock
The "analysis_movetime": 1.0, is in seconds.
