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
usage
const {buildExecutor} = require('webdriverio-parallel-retrier');
executeAsQueue();
async function 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();

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()

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()

processArgs
| Type: undefined
| null
| {[prop: string]: string}
Object with required process argumentss, use format prop name with - or --, example '--prop' or '-p'
processEnvVars
| Type: undefined
| null
| {[prop: string]: string}
Object with required process env variables, use format prop name upper snake_case, LOG_LEVEL
returns {executor: function}

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}
