我正在使用nock库来存根我的http调用.
不同的测试文件需要(‘nock’)并进行存根.
如果每个测试分别运行,则全部通过.
但是如果所有测试一起运行,后来的测试就会失败,因为而不是nock,实际的请求.
Consider below code snippet for example. It has two different
describe
blocks, each with multiple test cases. If I run this filenode node_modules/mocha/bin/_mocha test.js
then the first two tests will pass, but the third test (in differentdescribe
block) would fail because it would actually call the
/* eslint-env mocha */
let expect = require('chai').expect
let nock = require('nock')
let request = require('request')
let url = 'http://localhost:7295'
describe('Test A', function () {
after(function () {
nock.restore()
nock.cleanAll()
})
it('test 1', function (done) {
nock(url)
.post('/path1')
.reply(200, 'input_stream1')
request.post(url + '/path1', function (error, response, body) {
expect(body).to.equal('input_stream1')
done()
})
})
it('test 2', function (done) {
nock(url)
.post('/path2')
.reply(200, 'input_stream2')
request.post(url + '/path2', function (error, response, body) {
expect(body).to.equal('input_stream2')
done()
})
})
})
// TESTS IN THIS BLOCK WOULD FAIL!!!
describe('Test B', function () {
after(function () {
nock.restore()
nock.cleanAll()
})
it('test 3', function (done) {
nock('http://google.com')
.post('/path3')
.reply(200, 'input_stream3')
request.post('http://google.com' + '/path3', function (error, response, body) {
expect(body).to.equal('input_stream3')
done()
})
})
})
有趣的是,如果我执行console.log(nock.activeMocks()),那么我可以看到nock确实将URL注册为mock.
[ 'POST http://google.com:80/path3' ]
最佳答案 正如在这个
Github Issue中讨论的那样,nock.restore()删除了http拦截器本身.在调用nock.restore()之后运行nock.isActive()时,它将返回false.所以你需要在再次使用之前运行nock.activate().
解决方案1:
删除nock.restore().
解决方案2:
在测试中使用此before()方法.
before(function (done) {
if (!nock.isActive()) nock.activate()
done()
})
