本地模块引用 這段不錯
Jest Expect Methods https://jestjs.io/docs/en/expect
it = test
it('count > 30', async () => { await reqTarget.get("/members").expect(200) .then((res) => { //Can use foreach, more easy for(key in res.body){ //console.log(res.body\[key\].cou ); if (res.body\[key\].cou > 100) throw new Error("count: "+res.body\[key\].cou +" > 30"); //for vars value check message expect(res.body\[key\].cou ).toBeLessThan(30); } }); });
You can do：
1. reget git clone
2. npm install
3. remove node_module
4. npm install agin
5. npm audit fix
6. npm start or run
Sometime can Run.
