Could someone please demonstrate how to utilize the beforeEach function? For more information, visit: . I am particularly interested in seeing an example using promises, although a callback version would also be appreciated.
Below is a successfully functioning test that I have created:
'use strict';
const t = require('tap');
const tp = require('tapromise');
const app = require('../../../server/server');
const Team = app.models.Team;
t.test('crupdate', t => {
t = tp(t);
const existingId = '123';
const existingData = {externalId: existingId, botId: 'b123'};
const existingTeam = Team.create(existingData);
return existingTeam.then(() => {
stubCreate();
const newId = 'not 123'
const newData = {externalId: newId, whatever: 'value'};
const newResult = Team.crupdate({externalId: newId}, newData);
const existingResult = Team.crupdate({externalId: existingId}, existingData);
return Promise.all([
t.equal(newResult, newData, 'Creates new Team when the external ID is different'),
t.match(existingResult, existingTeam, 'Finds existing Team when the external ID exists')
]);
});
})
.then(() => {
process.exit();
})
.catch(t.threw);
function stubCreate() {
Team.create = data => Promise.resolve(data);
}
Prior to executing any tasks, my intention is to save existingTeam. Following its persistence, I aim to mock the behavior of Team.create. Subsequently, I wish to commence with the actual testing procedures. To streamline this process and avoid redundancy or the use of Promise.all, can beforeEach be employed?
How might I modify this scenario to incorporate the beforeEach method? Can you provide an illustrative example for reference?
