webdriverio-parallel-retrier

🛠 Development in progress, beta version

This library is a wrapper around `process-rerun`

The purpose of this library is - build simple and flexible interface for wdio framework parallel execution with rerun (on fail) possibility

buildExecutor
byIt
byFile

usage

const {buildExecutor} = require('webdriverio-parallel-retrier');

executeAsQueue();

  const testCaseRegPattern = /(?<=it\(').+(?=')/ig;
  const cwd = process.cwd();

  const result = await buildExecutor(resolve(cwd, './wdio.conf.js'), resolve(cwd, './built/specs'))
    .asQueue(testCaseRegPattern, ['test case it name 1', 'test case it name 2', 'test case it name 3'])
    .command({'--process-argument': 'process-argument-value'}, {ENV_VARIABLE: 'en-varialbe-value'})
    .executor({attemptsCount: 2, maxThreads: 1, logLevel: 'VERBOSE', longestProcessTime: 60 * 1000, pollTime: 100})
    .execute();

  console.log(result);
  if(result.retriable.length || result.notRetriable.length) {
    process.exit(1);
  }
}

buildExecutor

buildExecutor('./path/to/wdio.conf.js', './path/to/specs/folder')

arguments	description
`pathTowdioConfigFile`	Type: `string` Path to wdio config file
`pathToSpecFolderOrSpecsFilesList`	Type: `string` or `string[]` Path to specs folder, or list (array) with specs files path;

returns {byIt: function; byFile: function; asQueue: function}

byIt

buildExecutor(...args).byIt(/(?<=it\(').+(?=')/ig) or .byIt()

arguments	description
`itPattern`	Type: OPTIONAL `RegEx` RegEx for it title. example it('test item'); -> itRegEx = /(?<=it(').+(?=')/ig; in case of undefined library will define itPattern based on first symbol in it title;
`pathToSpecFolderOrSpecsFilesList`	Type: `string` or `string[]` Path to specs folder, or list (array) with specs files path;

returns {command: function}

byFile

buildExecutor(...args).byFile()

no arguments here

returns {command: function}

asQueue

buildExecutor(...args).asQueue(/(?<=it\(').+(?=')/ig, ['test1', 'test2', 'test 10']) or buildExecutor(...args).asQueue(['test1', 'test2', 'test 10'])

arguments	description
`itPattern`	Type: OPTIONAL `RegEx` RegEx for it title. example it('test item'); -> itRegEx = /(?<=it(').+(?=')/ig; in case of undefined library will define itPattern based on first symbol in it title;
`casesList`	Type: `string[]` List with tests what should be executed one by on `can be first argument, because itPattern is an optional`

returns {command: function}

command

buildExecutor(...args).asQueue(...args1).command({'--test': 'test'}, {ENV: 'test'}) or buildExecutor(...args).asQueue(...args1).command()

arguments	description
`processArgs`	Type: `undefined`
`processEnvVars`	Type: `undefined`

returns {executor: function}

executor

buildExecutor(...args).asQueue(...args1).command().executor({maxThreads: 1, attemptsCount: 2, logLevel: 'ERROR'})

arguments	description
`buildOpts`	Type: `object` Options for executor
`buildOpts.maxThreads`	Type: `number`, How many threads can be executed in same time Default threads count is 5
`buildOpts.attemptsCount`	Type: `number`, How many times can we try to execute command for success result in next cycle will be executed only faild command, success commands will not be reexecuted Default attempts count is 2
`buildOpts.pollTime`	Type: `number` , Period for recheck about free thread Default is 1 second
`buildOpts.logLevel`	Type: `string`, one of 'ERROR', 'WARN', 'INFO', 'VERBOSE', ERROR - only errors, WARN - errors and warnings, INFO - errors, warnings and information, VERBOSE - full logging Default is 'ERROR'
`buildOpts.currentExecutionVariable`	Type: `string`, will be execution variable with execution index for every cycle will be ++
`buildOpts.everyCycleCallback`	Type: `function`, Optional. everyCycleCallback will be executed after cycle, before next execution cycle. Default is false
`buildOpts.processResultAnalyzer`	Type: `function`, Optional. processResultAnalyzer is a function where arguments are original command, execution stack trace and notRetriable array processResultAnalyzer should return a new command what will be executed in next cycle or null - if satisfactory result
`buildOpts.longestProcessTime`	Type: `number`, In case if command execution time is longer than longest Process Time - executor will kill it automatically and will try to execute this command again. Default time is 45 seconds

returns {execute: async function}

execute

buildExecutor(...args).asQueue(...args1).command().executor(...args2).execute()

no arguments here

returns {retriable: string[]; notRetriable: string[]}
