How to Mock or Stub Process.argv

如何模拟或存根 process.argv 值以便它可以返回特定参数？

我试过像这样使用沙箱：

beforeEach(() => {
  sandbox.stub(process.argv.slice(2)[0], 'C:\\home\\project\\assignment').value('--local')
});

test("it replace value of node argument", () => {
    assert(process.argv.slice(2)[0], '--local')
});
    
afterEach(() =>{
    sandbox.restore()
})

但是我一直收到一个错误，提示尝试存根属性 *'C:\home\project ssignment' * of undefined

您可以通过编程修改

process.argv

const assert = require('assert');

describe('71476237', () => {
  let originalArgv;
  beforeEach(() => {
    originalArgv = process.argv;
  });

  afterEach(() => {
    process.argv = originalArgv;
  });

  it('it replace value of node argument', () => {
    process.argv = process.argv.concat(['node', 'C:\\home\\project\\assignment', '--local']);
    assert(process.argv.slice(2)[0], '--local');
  });
});

测试结果：

  71476237
    ✓ it replace value of node argument
