我正在尝试使用supertest进行一些测试。以下是我要测试的代码段:
it("should create a new org with valid privileges and input with status 201", function(done) {
request(app)
.post("/orgs")
.send({ name: "new_org", owner: "oldschool@aol.com", timezone: "America/New_York", currency: "USD"})
.expect(201)
.end(function(err, res) {
res.body.should.include("new_org");
done();
});
});
我在尝试测试res主体时遇到错误:
TypeError: Object #<Object> has no method 'indexOf'

这是supertest中的错误,还是我错误地格式化了我的测试?感谢

或者,这也应该有效:
res.body.should.have.property("name", "new_org");
另外,只是一个注释,但从逻辑上讲,我认为将它放入expects
的另一个调用而不是最终的回调中是有意义的。此功能也可以重复使用,因此我倾向于在可能的情况下将其放在可重复使用的位置:
var isValidOrg = function(res) {
res.body.should.have.property("name", "new_org");
};
it("should create a new org with valid privileges and input with status 201", function(done) {
request(app)
.post("/orgs")
.send({ name: "new_org", owner: "oldschool@aol.com", timezone: "America/New_York", currency: "USD"})
.expect(201)
.expect(isValidOrg)
.end(done);
});
现在你可以想象你正在为GET
测试/orgs/:orgId
,你可以重复使用相同的验证。

使用 Jest 这对我来说是这样的
it('should do something', async () => {
const test = await supertest(app)
.post('/some/endpoint')
.send({
someResource,
})
.expect(200);
expect(test.body.someKey).toBeDefined();
expect(test.body.someKey).toBe('someValue');
});

这可以改写如下:
res.body.name.should.equal("new_org");
这将解决错误。
答案 3 :(得分:0)
如果你的res.body是一个数组,你需要提供对象的索引res.body[res.body.length -1].name.should.equal("new_org")
- 如果你的属性是数组中的最后一个而没有被排序

要测试响应正文,您只需在expect
const { describe, it } = require('mocha');
const supertest = require('supertest');
describe('Validate API calls', () => {
it('create session post request should fail for invalid credentials', (done) => {
const data = { user_name: 'incorrect_username', password: 'INVALID' };
supertest(app).post('/api/session')
.send(data)
.expect('Content-Type', /json/)
.expect({ name: 'AuthenticationError', message: 'Unauthorized' })
.expect(401, done);
});
});
