protractor-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 protractor framework parallel execution with rerun (on fail) possibility

buildExecutor

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

arguments	description
pathToProtractorConfigFile	Type: string Path to protractor 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 or null or {[prop: string]: string} Object with required process argumentss, use format prop name with - or --, example '--prop' or '-p'
processEnvVars	Type: undefined or null or {[prop: string]: string} Object with required process env variables, use format prop name upper snake_case, LOG_LEVEL

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[]}
