我的頁面上有樹值。在一個事件之後,這些樹值應該改變。我想得到它們的初始值,然後在事件之後,我想看看它們是否正確增加。我可以在不將它們相互鏈接的情況下讀取和保存這些樹值嗎?
現在的代碼是:
let active_tours: number;
let active_drivers: number;
let total_capacity: number;
cy.get('[data-cy="txt-dashboard-active_tours"]')
.invoke('text')
.then((txt) => {
active_tours = parseInt(txt, 10);
cy.get('[data-cy="txt-dashboard-active_drivers"]')
.invoke('text')
.then((txt) => {
active_drivers = parseInt(txt, 10);
cy.get('[data-cy="txt-dashboard-total_capacity"]')
.invoke('text')
.then((txt) => {
total_capacity = parseInt(txt, 10);
cy.createTour('email', 'password').then(
(response: any) => {
cy.get('[data-cy="txt-dashboard-active_tours"').should(($div) => {
expect($div.text().trim()).equal((active_tours + 1).toString());
});
cy.get('[data-cy="txt-dashboard-active_drivers"').should(($div) => {
expect($div.text().trim()).equal((active_drivers + 1).toString());
});
cy.get('[data-cy="txt-dashboard-total_capacity"').should(($div) => {
expect($div.text().trim()).equal(
(total_capacity + response.vehicle.capacity).toString()
);
});
}
);
});
});
});
要最小化異步回調,請使用別名和this
屬性,請參閱共享上下文
it('minimizes callbacks', function () { // must be function here
cy.get('[data-cy="txt-dashboard-active_tours"]')
.then($el => parseInt($el.text(), 10))
.as('tours') // saved as this.tours
cy.get('[data-cy="txt-dashboard-active_drivers"]')
.then($el => parseInt($el.text(), 10))
.as('drivers') // saved as this.drivers
cy.get('[data-cy="txt-dashboard-total_capacity"]')
.then($el => parseInt($el.text(), 10))
.as('capacity') // saved as this.capacity
cy.createTour('email', 'password').then(response => {
cy.get('[data-cy="txt-dashboard-active_tours"')
.then($el => parseInt($el.text(), 10))
.should(tours2 => expect(tours2).to.eq(this.tours + 1))
cy.get('[data-cy="txt-dashboard-active_drivers"]')
.then($el => parseInt($el.text(), 10))
.should(drivers2 => expect(drivers2).to.eq(this.drivers + 1))
cy.get('[data-cy="txt-dashboard-total_capacity"')
.then($el => parseInt($el.text(), 10))
.should(capacity2 => {
expect(capacity2).to.eq(this.capacity + response.vehicle.capacity)
})
})
})
如果你想刪除一些代碼重複
Cypress.Commands.add('saveNumber', (selector, alias) => {
cy.get(selector).then($el => parseInt($el.text(), 10)).as(alias)
})
it('minimizes callbacks', function () { // must be function here
cy.saveNumber('[data-cy="txt-dashboard-active_tours"]', 'tours')
cy.saveNumber('[data-cy="txt-dashboard-active_drivers"]', 'drivers')
cy.saveNumber('[data-cy="txt-dashboard-total_capacity"]'), 'capacity')
cy.createTour('email', 'password').then(response => {
cy.saveNumber('[data-cy="txt-dashboard-active_tours"]', 'tours2')
.should(() => expect(this.tours2).to.eq(this.tours + 1))
cy.saveNumber('[data-cy="txt-dashboard-active_drivers"]', 'drivers')
.should(() => expect(this.drivers2).to.eq(this.drivers + 1))
cy.saveNumber('[data-cy="txt-dashboard-total_capacity"]'), 'capacity')
.should(() => {
expect(this.capacity2).to.eq(this.capacity + response.vehicle.capacity)
})
})
})
