Can you please test the specific break values, not just the number of classes?

[dvrohan]

I added the breakpoint values for a few tests. Is that what you meant? For a few tests it is not possible to know the values beforehand.

[petrasovaa]

The tests are slow. There are couple options to optimize this. If I understand this correctly the fixture runs for each test, consider running it just once if appropriate. Also running db.execute in loop is expensive, see the manual page of db.execute to avoid that.

[dvrohan]

I have used a single db.execute query instead of inside a loop. I am also using a module scope for shared state. Please let me know if this works.

It's still the longest pytest (see the windows CI):

Perhaps mark the large data test as skipped and see if it helps.

I have reduced the number of points to 100 instead of 1000. I think that should reduce the processing time significantly.

It looks good now, thanks!
