i've noticed projects such bundler require spec_helper in each spec file

i've noticed rspec takes option --require, allows require file when rspec bootstrapped. can add .rspec file, added whenever run rspec no arguments.

are there disadvantages using above method might explain why projects such bundler choose require spec_helper in each spec file?

i don't work on bundler can't speak directly practices. not projects check-in .rspec file. reason file, current convention, has personal configuration options general output / runner preferences. if required spec_helper there, others wouldn't load it, causing tests fail.

another reason, not tests may need setup performed spec_helper. more there have been groups of rubyists trying move away loading many dependencies test. making explicit when spec_helper required in test people have idea may going on. also, running single test file or directory doesn't need setup faster.

in reality, if of tests requiring spec_helper , you've make clear convention on project there's no technical reason can't or shouldn't it. may initial surprise new people join project.

i have google question , find answer in day. know, data design many many table have list column,and mark pk , fk. why er-diagram have find this? data design process of designing database. main output of data design detailed logical data model of database. some people data design includes of needed logical , physical design choices , physical storage parameters needed generate design in data definition language. technically, database analysis, database analysts (dbas) trained do. while person can both data design , database analysis, these 2 different tasks. data design models data. database analysis takes model , applies 1 or more database engines (relational, hierarchical, nosql). a logical data model 1 of main outputs of data design. data model represented entity relationship diagram, or er diagram.
