当我尝试实现时，在 express 中的“npm test”之后“找不到命令”（参见 jest、supertest、env）

Question

I am trying to implement TESTCODE by jest and supertest in express.

but when i type npm test in vsc terminal, it made the following issue:

'.env' file already has private data. So it works when I try to signup and signin, but when i do npm test it made the issue.

I think it might because because jest(?) can't read .env. file properly.

vsc terminal

env-cmd ./.env jest --watch

./.env: line 1: DATABASE_USERNAME: command not found
./.env: line 2: DATABASE_PASSWORD: command not found
./.env: line 3: DATABASE_NAME: command not found
./.env: line 4: DATABASE_HOST: command not found
./.env: line 5: DATABASE_PORT: command not found
npm ERR! Test failed.  See above for more details.

Answer 1

I ran your test script and it worked but make sure:

1. Enough permission is granted for the project directory, run chmod -R a+rwx /your/project/path

2. File structure is correct

• project
  • .env
  • package.json

Answer 2

Thank you for your advice.

My file structure is

project
    server
        .env
        package.json

First time when I type 'npm test' it made this result => spawn./.env EACCES

So I typed 'chmod -R 777 server/ ', and 'npm test' Then it made this result

 > env-cmd ./.env jest --watch

./.env: line 1: DATABASE_USERNAME: command not found
./.env: line 2: DATABASE_PASSWORD: command not found
./.env: line 3: DATABASE_NAME: command not found
./.env: line 4: DATABASE_HOST: command not found
./.env: line 5: DATABASE_PORT: command not found
npm ERR! Test failed.  See above for more details.

Then I typed what you said 'chmod -R a+rwx server/', and 'npm test' Then it made same result like up thing……….
