How to deal with complex Factory Bot associations in RSpec tests

What’s the best way to handle tests that involve complex setup data? You want to test object A but it needs database records for objects B, C and D first.I’ll describe how I address this issue but first let me point out why complex setup data is a problem.Why complex setup data is a problemComplex setup data can be a problem for two reasons. First, a large amount of setup data can make for an Obscure Test, meaning the noise of the setup data drowns out the meaning of the test.Second, complex setup data can be a problem if it results in duplication. Then, if you ever need to change the setup steps, you’ll have to make the same change in multiple places.
