Assuming I have these test cases (with jest and supertest):
describe('Test actors', async () => {
const params = { /* ... */ }
let actorId
test(`Create an actor ${actorsUrl}`, async () => {
const response = await request(app.callback())
.post(actorsUrl)
.send(params)
.set('Accept', 'application/json')
.set('Content-Type', 'application/json')
.expect(200)
expect(response.body.name).toBe(params.name)
expect(response.body.address).toBe(params.address)
actorId = response.body.id
})
test(`Get the actor created ${actorsUrl}/${actorsUrl}`, async () => {
const response = await request(app.callback())
.get(`${actorsUrl}/${actorsUrl}`)
.set('Accept', 'application/json')
.expect(200)
expect(response.body.name).toBe(params.name)
expect(response.body.address).toBe(params.address)
})
})
I want to wait for first test to finish before running the second one (because the first one creates a Actor and the second one ask the API for the created Actor). Running this code fails because the actor is not already created.
Is there a way to wait for the first test to finish before calling the second one?
jestjs is just a wrapper over jasmine, and in many cases it relies on jasmine's rules.
Therefore, you can make use of the same done callback that is passed to the test function:
test(`Create an actor ${actorsUrl}`, async (done) => {
const response = await request(app.callback())
.post(actorsUrl)
.send(params)
.set('Accept', 'application/json')
.set('Content-Type', 'application/json')
.expect(200)
expect(response.body.name).toBe(params.name)
expect(response.body.address).toBe(params.address)
actorId = response.body.id
done();
})
test(`Get the actor created ${actorsUrl}/${actorsUrl}`, async (done) => {
const response = await request(app.callback())
.get(`${actorsUrl}/${actorsUrl}`)
.set('Accept', 'application/json')
.expect(200)
expect(response.body.name).toBe(params.name)
expect(response.body.address).toBe(params.address)
done();
})
You can read more about that in jest's async documentation
