This library is a wrapper around `process-rerun`

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

usage

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

executeByFile();
async function executeByFile() {
  const cwd = process.cwd();
  const result = await buildExecutor(resolve(cwd, './path/to/specs'))
    .byFile()
    .command({'--process-argument': 'process-argument-value'}, {ENV_VARIABLE: 'en-varialbe-value'})
    .executor({attemptsCount: 2, maxThreads: 5, logLevel: 'VERBOSE', longestProcessTime: 60 * 1000, pollTime: 100})
    .execute();

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

executor

buildExecutor(...args).byFile(...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
