Pre & Post Test Operations
Similarly, we have another method called afterEach which simply performs some specified operations after each test.
Sometimes, we would want to execute some code only once, before any tests in that scope are executed. To achieve this, we can enclose the respective code into a beforeAll block, which follows the same syntax as a beforeEach block:
beforeAll(() => {
// before any tests are executed
});
Similarly, we can also specify some code to be executed after all the tests in that scope are executed by using a afterAll block:
afterAll(() => {
// after all the tests have been executed
});

Can you explain the difference between beforeEach and beforeAll?
How do I decide when to use afterEach vs afterAll?
Can you give an example of using these hooks together in a test file?
Fantastisk!
