Ptor-xunit-grep-builder NPM

Description

Given XML reports from protractor, this library will construct the grep param to run the failing tests

Supports sharded configuration

HOW TO USE

install this library

npm install -g ptor-xunit-grep-builder

configure your protractor to export reports to xml (in onPrepare() phase )

// for sharded configuration
jasmine.getEnv().addReporter(new jasmineReporters.JUnitXmlReporter({
  consolidateAll: true,
  savePath: savePath + '/each',
  filePrefix: 'failed-test-' + uuid()
}));

// for regular configuration
jasmine.getEnv().addReporter(new jasmineReporters.JUnitXmlReporter({
  consolidateAll: true,
  savePath: savePath
}));

// alternatively, to have support for specs as well
// tested on configuration for running in parallel.
return global.browser.getProcessedConfig().then((config) => {
  const filename = () => {
    try {
      return config.specs[0].split('/').slice(-1)[0]; // return entire name (e.g. name.ptor.js) - this will be appended with .xml later on
    } catch (e) {
      return 'failed-test-' + uuid();
    }
  };
  const filenameValue = filename();
  global.jasmine.getEnv().addReporter(new jasmineReporters.JUnitXmlReporter({
    consolidateAll: true,
    savePath: savePath + '/each/',
    filePrefix: filenameValue
  }));

  logger.info('filename is', filenameValue);
});

add a retry code to you build script - her is an example

#!/usr/bin/env bash

print_attempt(){
    echo "#########################################################################################"
    echo "                          attempt ${i}                                                   "
    echo "#########################################################################################"
}

clean_reports () {
rm -rf ./reports/protractor/**/failed-test-*.xml
}

run_tests () {
    print_attempt
    echo PTOR_SUITE=${PTOR_SUITE}
    GREP_PARAMS=`ptor-xunit-grep-builder --tests --files=./reports/protractor/*/each/*.xml`
    echo "count of all tests"
    ptor-xunit-grep-builder --count --tests --files=./reports/protractor/*/each/*.xml
    SPECS_PARAMS=`ptor-xunit-grep-builder --filenames --files=./reports/protractor/*/each/*.xml`
    echo "GREP PARAMS=${GREP_PARAMS}"
    echo "SPECS PARAMS=${SPECS_PARAMS}"

    if  [ "$GREP_PARAMS" = "" ]; then
        echo "ERROR::: grep params is empty but retrying..."
        exit 1
    fi

    if  [ "$SPECS_PARAMS" = "" ]; then
        echo "ERROR::: specs params is empty but retrying..."
        exit 1
    fi

    clean_reports
    ./node_modules/.bin/protractor --specs=${SPECS_PARAMS} --grep="${GREP_PARAMS}" protractor.conf.js
}

first_run () {
    print_attempt
    clean_reports
    ./node_modules/.bin/protractor --suite=${PTOR_SUITE} protractor.conf.js
}
i=1
# run first time and then retry over and over again
first_run || ( for i in 2 3 4 5 6 7 8 9; do run_tests $i && break || sleep 5; done )
