Starting a new testing project, and I'm wondering if it's a bad practice to set up all the necessary seed data in a beforeAll to run the test suite then or if isolation is critical so that work should be done in a beforeEach. We have an application that requires a decent amount of data to get up and run, so we're trying to figure out what might be the best practices.

• Avoid Nesting when you're Testing

Test Data: To BeforeAll or to BeforeEach
