Jasmine JavaScript Testing Framework Jasmine JavaScript Knowledge 5

Question 1

What is the purpose of `beforeAll` in Jasmine?

Accepted Answer

Runs setup code once before all specs in a describe block

Answer

beforeAll executes its callback exactly once before any spec inside the enclosing describe runs.

Question 2

How does `afterAll` differ from `afterEach` in Jasmine?

Accepted Answer

afterAll runs once after all specs; afterEach runs after every spec

Answer

afterAll is a single teardown that fires after the last spec in the suite, while afterEach fires after each individual spec.

Question 3

What does the `xdescribe` function do in Jasmine?

Accepted Answer

Disables all specs inside the describe block

Answer

xdescribe marks an entire describe block as pending, so all specs inside are skipped without being removed.

Question 4

Which function marks a single spec as focused so only it runs in a suite?

Accepted Answer

fit()

Answer

fit() (focused it) causes Jasmine to run only that spec and skip all non-focused specs in the suite.

Question 5

What does calling `pending()` inside a Jasmine spec do?

Accepted Answer

Marks the spec as pending regardless of other assertions

Answer

Calling pending() anywhere in a spec immediately marks it as pending and stops execution of that spec.
