Examples
Assertions
In this example, we are asserting the response from random-user api. The results from the server are dynamic, so we are using the eachLike matcher in expectJsonMatch to validate the type of the values instead of the content.
resultsshould be an array of objects.- each object in
resultsshould containgenderand it should be a string
- each object in
js
const { spec } = require('pactum');
const { like, eachLike } = require('pactum-matchers');
await spec()
.get('https://randomuser.me/api')
.withQueryParams('results', 2)
.expectJsonMatch({
"results": eachLike({
"gender": like("male")
}
});
Mock Server
Interactions in mock server will help in building contracts between services. Matching rules are defined in interaction responses to make them more reliable during contract testing.
In some scenarios, we might want to return multiple items while using eachLike as by default, it only returns one element. To overcome it, use items property.
js
const { mock } = require('pactum');
const { eachLike } = require('pactum-matchers');
// return only one user
mock.addInteraction({
request: {
method: 'GET',
path: '/api/users'
},
response: {
status: 200,
body: eachLike({
"name": "mom",
"age": 50
})
}
});
js
const { mock } = require('pactum');
const { eachLike } = require('pactum-matchers');
// return multiple users - dad and brother
mock.addInteraction({
request: {
method: 'GET',
path: '/api/users'
},
response: {
status: 200,
body: eachLike({
"name": "mom",
"age": 50
}, items: [
{
"name": "dad",
"age": 55
},
{
"name": "brother",
"age": 30
}
])
}
});
