如何用 commonbeforeAll
和编写自己的 Jest 预设afterAll
?
我很困惑,似乎没有相关文档。
您可以通过这种方式扩展环境:
笑话配置:
module.exports = {
testEnvironment: './suites/future/jest.myEnv.js',
};
jest.myEnv.js
: _
const NodeEnvironment = require('jest-environment-node');
const start = async () => {
console.log('START');
};
const stop = async () => {
console.log('STOP');
};
class TestEnvironment extends NodeEnvironment {
constructor(config) {
super(config);
}
async setup() {
await super.setup();
await start();
}
async teardown() {
await stop();
await super.teardown();
}
runScript(script) {
return super.runScript(script);
}
}
module.exports = TestEnvironment;
