• logLevel: (string) error, warn, info, verbose, debug, silly. Default: silly. Learn usage here.

• exitOnFail: (boolean) Exit after a set of tests fails so it won't execute tests for the next sets of parameters if there are some. Default: false.

Example:

{
  /* kaukau options */
  "enableLogs": true,
  "exitOnFail": false,
  "files": [], // Test files/directories to execute. (e.g.: [ "tests/test01.js" ])
  "options": {
    /* mocha options */
  },

  /* sets of parameters */
  "parameters": [
    {

      },
      "mochaOptions":{

Helpers

The following helpers come with kaukau.

Parameters

Usefull if you need to run the same tests with different parameters and options.

If you define sets of parameters in your configuration, the test scripts will be executed for each set. You can access parameters for the current set running as:

describe('test 01', function() {

  const { params } = this.ctx.kaukau;

  /**
   * In configuration:
   * parameters: [
   *  {
   *    host: "test.com",
   *    credentials: {
   *      email: "test@test.com"
   *    }
   *  }
   * ]
   */
  let host = params('host'); // "test.com"
  let email = params('credentials.email'); // "test@test.com"
});

Parameters can overwrite the main configuration by using the properties kaukauOptions and mochaOptions.

kaukauOptions can overwrite files and ext.

mochaOptions can overwrite all mocha options.

Logger

Logging utility.

describe('test 02', function() {

  const { logger } = this.ctx.kaukau;

  logger.silly('silly level');
  logger.debug('debug level');
  logger.log('verbose level');
  logger.info('info level');
  logger.warn('warn level');
  logger.error('error level');
});

Tester

Example:

// chai@4
const { expect } = require('chai');

describe('test 03', function() {

  const { params, tester } = this.ctx.kaukau;

  // set default options (axios.defaults)
  tester.setRequestDefaults({});
  
  // overwrite default options
  tester.updateRequestDefaults({});
  
  /* request */
  
  it('should be ok', async () => {
    const res = await tester.request({
      method: 'GET',
      url: params('host')
    });
    expect(res.status).to.equal(200);
  });
  
  // or
  
  tester.save({
    method: 'GET',
    url: params('host')
  });
  
  it('should be ok', function(){
    expect(this.err).to.equal(null);
    expect(this.res.status).to.equal(200);
  });
});
