Häufige Annahme
A test setup file configured under setupFiles has access to test framework globals like beforeEach, afterEach, and expect.extend.
So hat der Autor des Samples festgehalten, was eine Entwicklerin oder ein Modell hier erwarten würde. Der Vertrag darunter ist das, was tatsächlich lief.
Contract
- assert running Jest with test framework hooks in setupFiles fails with ReferenceError: beforeEach is not defined because the framework environment is not yet initialized
- assert setupFiles executes in the isolated test environment before the test framework and can configure environment globals
- assert setupFilesAfterEnv executes after test framework initialization, allowing beforeEach hooks and expect.extend matchers to run across test suites
- assert jest-config normalize correctly resolves <rootDir> tokens for both setupFiles and setupFilesAfterEnv into absolute paths
