摩卡柴测试用例不会自动终止

Question

I have written following test cases on mocha-chai and it works fine and shows the all results passed successfully. But it does not terminate the execution after successfully passed all 6 test cases. I don't know what is the reason that why my test case does not terminate automatically, I need to click CTRL+C to terminate the test case.

I don't know what is the reason test has been successfully passed but does not terminate. I have also written done() at the end of the test case but still it doesn't work

I have used PostgreSQL as database and NodeJS as backend server.

test.js

const { colors } = require('mocha/lib/reporters/base');

colors.pass = 32;
const { describe, it } = require('mocha');
const { expect } = require('chai');
const request = require('superagent');
const should = require('should');
const fs = require('fs');
const path = require('path');
const moment = require('moment-timezone');

const envPath = path.join(__dirname, '.env');
require('dotenv').config({ path: envPath });

const Sequelize = require('sequelize');
const db = require('../db/models');

// Test that server is running or not
describe('Unit tests for add user', () => {
    // Gateway api test case and it's works fine
});

// Read the test cases stored from database and stored in an array
describe('Test Cases', () => {
    // Read the test cases from database
});

// Test case to write test data in csv and upload the csv and insert user information in csv

describe('Process data user csv', () => {    

    it('create user csv to write data in csv', done => {
        // Create user csv from test data and it's passed and successfully completed it
    });

    it('Upload user csv and insert the user in the database with accurate data', done => {
        // Upload user csv and insert user information from csv and it's passed and successfully completed it
    });

    it('verify user information from user table', done => {
        // This method verifies the user data stored user table, which has inserted in test case.
        // Sequlieze query which fetch the user information 

        TestService.executeQuery(
            dbQuery.qGetUserDetails,
            {
            email: arrTestCases[0].expected_result.email,
            },
            'select'
        )
        .then(data => {
            should(data[0].email).equal(arrTestCases[0].expected_result.email);
            done();
        });        
    });
  });
});

app.query.js

/**
 * @description default queries
 */
module.exports = {
  qGetUserDetails: `select * from "Users" where email = :email and is_active = true and is_deleted = false`,
};

Test.service.js

/**
 * @class TestService
 */
const Sequelize = require('sequelize');
const db = require('../db/models');

module.exports = class TestService {

  /**
   * @static execute query
   * @param {*} query
   * @param {*} replacements
   * @param {*} operation
   * @memberof TestService
   */
  static executeQuery(query, replacements, operation) {
    return new Promise((resolve, reject) => {
      let queryType;
      if (operation === 'insert') {
        queryType = Sequelize.QueryTypes.INSERT;
      } else if (operation === 'update') {
        queryType = Sequelize.QueryTypes.UPDATE;
      } else if (operation === 'select') {
        queryType = Sequelize.QueryTypes.SELECT;
      } else if (operation === 'delete') {
        queryType = Sequelize.QueryTypes.DELETE;
      } else {
        queryType = Sequelize.QueryTypes.SELECT;
      }
      return db.sequelize
        .query(query, { replacements, type: queryType, raw: true })
        .then(data => resolve(data))
        .catch(err => reject(err));
    });
  }
};

I don't know what is the reason test has been successfully passed but does not terminate.

You're not closing your database handle when all tests have been run, which means that Node.js doesn't know that you're done.

You can add a root-level after hook to close it:

after(() => {
  sequelize.close();
});
