selenium download ensure

[TroutZen]

I can't seem to get this script to work

require('selenium-download').ensure('./bin', function(error) {  
   if (error) {
     return console.log(error);
   } else {
     console.log('✔ Selenium & Chromedriver downloaded to:', './bin');
   }
});

[testium] grabbing selenium standalone server 2.53.0
Starting selenium server... There was an error while starting the Selenium server:

Error: Invalid or corrupt jarfile ./node_modules/nightwatch/bin/selenium.jar

Seems to be trying to start the server before the installation has completed? Is there a way to defer this in node?

Hi @TroutZen thanks for feedback!
Yes, the .ensure only checks that the driver has been downloaded.
We have a postinstall command in our package.json which runs the require('selenium-download').ensure( after all node_modules have been installed, that way the first time you attempt to run nightwatch both selenium.jar and chromedriver have already been installed.
see:

postinstall does not download the jar file into the bin folder on windows 8

@jpfernandezl thanks very much for the feedback! (_it's meant to be cross-platform... but we do not maintain the selenium-download package, so please inform our friends @groupon by raising an issue: https://github.com/groupon/selenium-download/issues explain exactly what OS version and method you used. 👍
