How can I mock APIs in Express for testing purposes?
You can use libraries like nock
or express-mock-server
to mock APIs in your Express application.
Can you show me a simple example using nock
?
Sure! First, install nock
using npm. Then, you can set up a mock like this: nock('http://example.com').get('/api').reply(200, { success: true });
.
What if I want to mock multiple endpoints?
You can chain multiple nock
calls or use nock
's persist()
method to keep the mocks active for multiple requests.
