I’ve never seen Claude do that. It makes the new tests pass by fixing previously unknown bugs in my experience.
I had it do it about a month ago. It changed test data which caused another test to fail and instead of isolating things it decided to flip an assert.
I love Claude but on several occasions I've had it do some really funky stuff just to get tests passing
