在 Cypress 测试中模拟 imgur 请求/响应

我正在尝试存根 imgur 请求和响应。根据 API 文档 ,我可以发出如下匿名请求:
curl --location --request POST 'https://api.imgur.com/3/image' \
--header 'Authorization: Client-ID {{clientId}}' \
--form 'image=R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7'
响应如下(我已为其创建了一个装置,即
navbar-logo-image.json
)
{
"data": {
"id": "orunSTu",
"title": null,
"description": null,
"datetime": 1587998106,
"type": "image/png",
"animated": false,
"width": 2100,
"height": 1709,
"size": 138557,
"views": 0,
"bandwidth": 0,
"vote": null,
"favorite": false,
"nsfw": null,
"section": null,
"account_url": null,
"account_id": 0,
"is_ad": false,
"in_most_viral": false,
"tags": [],
"ad_type": 0,
"ad_url": "",
"in_gallery": false,
"deletehash": "N9YaI4CIkq3rIar",
"name": "",
"link": "https://i.imgur.com/12gZbNU.png"
},
"success": true,
"status": 200
}
我的测试场景如下:
it('should allow the user to select a navbar component and replace a logo', () => {
cy.server();
cy.route({
url: '/3/image',
method: 'POST',
response: "fixture:navbar-logo-image.json",
}).as('imgurRequest');
cy.getIframeBody('builder-showcase').find('[data-cy="navbar-component"]').eq(0).click();
cy.getIframeBody('builder-showcase').find('[data-cy="navbar-logo-image"]').eq(0).click();
cy.get('[data-cy="builder-sidebar-menu-select-image-navbar"]').eq(0).click();
const navbarLogoImage = 'images/navbar-logo-image.png';
cy.get('[data-cy="image-file-input"]').attachFile(navbarLogoImage);
cy.get('[data-cy="image-alt-text"]')
.clear()
.type('Twitter logo image');
cy.get('.source-image').invoke('attr', 'src')
.then(uploadedLogoImage => {
expect(uploadedLogoImage).to.contain('iVBORw0KGgoAAAANSUhEUgAACDQAAAatCAYAAAAmAogfAAAgAElEQVR4XuzdC5icdXn38');
});
cy.get('[data-cy=image-select-save]').click();
});
API 调用在此行触发
cy.get('[data-cy=image-select-save]').click();
。我想拦截它并将帖子发布到虚拟 API,然后提供虚拟响应。我该怎么做?

如果
cy.request()
中的参数正确,则您已设置为拦截调用并模拟对 json 装置的响应。然后,您可以使用
cy.wait()
获取包含请求和响应的 http 对象:
cy.get('[data-cy=image-select-save]').click();
cy.wait('@imgurRequest').then(xhr => {
// do something with the xhr object
});
确保您的请求不是
fetch
类型,因为 cypress 尚无法捕获
fetch
请求。另外,我建议在
cy.request()
中的 url 参数中使用 glob 模式,例如
url: '*/3/image'
