我正在使用与以下内容非常类似的东西来使用Mocha执行一系列API测试。这很棒,但它需要为每个测试单独调用API。 我想使用相同的API调用并针对该响应运行多个测试。我一直在阅读您可以使用before
来执行此操作,但实际上网络上没有任何示例显示它使用API调用?
var chai = require('chai');
var request = require('request');
var async = require('async');
var assert = chai.assert,
expect = chai.expect,
should = chai.should();
describe('/', function () {
it('should return 200', function (done) {
request.get('http://localhost:8000', function (err, res, body) {
res.should.have.status(200);
done();
});
});
it('should say "Hello, world!"', function (done) {
request.get('http://localhost:8000', function (err, res, body) {
body.should.have.property('type', 'aType');
done();
});
});
});
答案 0 :(得分:5)
您可以使用before
函数执行此操作,如此...
var chai = require('chai');
var request = require('request');
var async = require('async');
var assert = chai.assert,
expect = chai.expect,
should = chai.should();
describe('/', function () {
var firstRequest;
before(function(done) {
request.get('http://localhost:8000', function(err, res, body) {
firstRequest = {
err:err,
res:res,
body:body
};
done();
});
});
it('should return 200', function (done) {
firstRequest.res.should.have.status(200);
done();
});
it('should say "Hello, world!"', function (done) {
firstRequest.body.should.have.property('type','aType');
done();
});
});
然而,除非你有充分的理由这样做,否则我认为你只需要合并测试就可以了。
var chai = require('chai');
var request = require('request');
var async = require('async');
var assert = chai.assert,
expect = chai.expect,
should = chai.should();
describe('/', function () {
it('should return 200 and say "Hello, world!"', function (done) {
request.get('http://localhost:8000', function (err, res, body) {
res.should.have.status(200);
body.should.have.property('type', 'aType');
done();
});
});
});
如果测试失败,即使有两个断言,Mocha也会报告失败的具体原因。
