我正在尝试通过代码启动和停止无服务器应用程序。一旦所有测试通过,我就能启动和停止它。但是,如果测试失败globalTeardown
,请不要运行。您可以在此处检查示例项目:https://github.com/bilalsha/sls-test-jest/tree/fail_test
teardown.js
module.exports = async function() {
let slsOfflineProcess = global.__SERVERD__;
slsOfflineProcess.stdin.write('q\n');
slsOfflineProcess.stdin.pause();
await slsOfflineProcess.kill('SIGINT');
console.log('Serverless Offline stopped');
};
output
7 | expect(res.statusCode).toEqual(200);
> 8 | expect(res.body).toEqual('Go Serverless v1.0! Your function executed successfully!');
| ^
9 | });
10 | });

仅将文档设置为bail: true
时,jest.config.js中就出现问题了
https://github.com/bilalsha/sls-test-jest/blob/fail_test/test/jest.config.js#L3
文档说,如果保释金为真,则与在第一次失败后停止测试相同。
https://jestjs.io/docs/en/configuration#bail-number--boolean
我会尝试更改bail: 0
(默认设置),并查看它是否产生了预期的行为。

您可以做的就是添加一个包含afterAll
函数的脚本:
afterAll(() => {
console.log("I ran");
});
并将脚本添加到setupFiles
或setupFilesAfterEnv
。就我而言,我弹出了一个测试失败的react poc代码:
在package.json
的Jest配置中,存在以下条目:
"jest": {
...
"setupFilesAfterEnv": [
"<rootDir>/src/setupTests.js"
],
...
}
因此,我在下面的setupTests.js
中添加了该子句:
// jest-dom adds custom jest matchers for asserting on DOM nodes.
// allows you to do things like:
// expect(element).toHaveTextContent(/react/i)
// learn more: https://github.com/testing-library/jest-dom
import '@testing-library/jest-dom/extend-expect';
afterAll(() => {
console.log("I ran");
});
现在,当我运行测试时,结果如下:
FAIL src/App.test.js
✓ renders learn react link (14ms)
✕ renders class (5ms)
● renders class
expect(jest.fn()).toHaveBeenCalledTimes(expected)
Expected number of calls: 1
Received number of calls: 0
18 | // someClass.someProp = "";
19 | render(<App />);
> 20 | expect(track).toHaveBeenCalledTimes(1);
| ^
21 | });

即使测试失败,您仍可以看到I ran
在那。这是您可以使用的替代方法,因为您已经悬赏金了,我认为也许解决问题比为什么globalTeardown
不起作用更为重要。
