使用 SuperTest 和 Jest 测试 TypeScript Apollo Server:'request.post' 不是函数
Using SuperTest and Jest to test TypeScript Apollo Server: 'request.post' is not a function
我正在尝试使用 SuperTest 来测试 Apollo 服务器,这是在 this Stack Overflow question 的第一个答案之后,以及我找到的其他示例。
我的完整代码是
// /__test__/index.test.ts
import * as request from 'supertest';
let postData = {
query: `query allArticles{
allArticles{
id
}
}`,
operationName: 'allArticles'
};
test('basic', async () => {
try {
const response = request
.post('/graphql')
.send(postData)
.expect(200); // status code that you expect to be returned
console.log('response', response);
} catch (error) {
console.log(`error ${error.toString()}`);
}
});
然而当我 运行 这与 Jest
"test": "jest --detectOpenHandles --colors"
我明白了
PASS __test__/index.test.ts
● Console
console.log
error TypeError: request.post is not a function
at __test__/index.test.ts:20:11
就其价值而言,我不认为这是 "passing" 测试,因为我在 expect
中输入什么并不重要。
如果我更改我的代码以完全遵循 Stack Overflow(将 GraphQL 端点直接传递给请求
test('basic', async () => {
try {
const response = request('/graphql')
.post('/graphql')
.send(postData)
.expect(200); // status code that you expect to be returned
console.log('response', response);
} catch (error) {
console.log(`error ${error.toString()}`);
}
});
我明白了
PASS __test__/index.test.ts
● Console
console.log
error TypeError: request is not a function
at __test__/index.test.ts:20:11
我在 Node 12.14
下使用 ts-jest
和 运行ning
我的 tsconfig.json
是
{
"compilerOptions": {
"target": "ES6",
"lib": [
"esnext",
"dom"
],
"skipLibCheck": true,
"outDir": "dist",
"strict": false,
"forceConsistentCasingInFileNames": true,
"esModuleInterop": true,
"module": "commonjs",
"moduleResolution": "node",
"resolveJsonModule": true,
"isolatedModules": true,
"sourceMap": true,
"alwaysStrict": true
},
"exclude": [
"node_modules",
"**/*.test.ts",
"**/*.mock.ts"
]
}
我的jest.config
是
module.exports = {
preset: 'ts-jest',
testEnvironment: 'node'
};
感谢任何线索!
supertest
没有导出,这就是为什么需要将导入更改为
import {default as request} from 'supertest';
request
现在是您可以调用的导出工厂函数:
const response = request('/graphql')
.post('/graphql')
...
