@volodya-lombrozo take a look, please

[h1alexbel]

@volodya-lombrozo yes, definitely. I didn't check the speed of code in @BeforeAll section that loads a model. 16-19ms for tests execution, and ~3seconds for model loading. I will implement some sort of caching to speed up it a bit. Is 1.5 second of model load will be considered as acceptable? WDYT?

[volodya-lombrozo]

@h1alexbel Yes, it would be great. 1.5 seconds is acceptable. Please, go ahead.

@volodya-lombrozo updated pull request, take a look again, please

[h1alexbel]

First run should take ~3 seconds, model will be cached in src/test/resources/ml/cached.bin. Next test executions should take no longer than 1.5 seconds
