Node NPM error: URIError: URI malformed at decodeURIComponent (native) at Url.parse


Problem: If you are using node and accidentally change your proxy settings every time  you run npm you get something like this:

NPM error: URIError: URI malformed at decodeURIComponent (native) at Url.parse

What Happened there?
Once a bad URL makes it in to the config file, it is broken, but you as the operator are unaware until you do another operation. This was confusing when I was setting both HTTP and HTTPS proxies. It delayed me from finding the real problem. To resolve this issue it would be great if the URLs were validated before they went in the file. This would reduce confusion.

How to solve this?

  1. You cannot reset npm config from command-line because the npm command doesn't work anymore
  2. Reinstalling node will not help
  3. Locate where npm has its global settings stored: C:\Users\Ady\.npmrc
  4. edit the file and everything is back to normal!

This solves a similar but different problem:

Software Testing @ Microsoft

In continuation from my previous  series of posts  targeting testing in top few companies from the technology space. After  Software Testing @Facebook  and @Google  we shall now look at Microsoft: Testing@Microsoft Software Development Engineers in Test (SDETs) are usually just called Test and sometimes Software Testing. SDETs are responsible for maintaining high testing and qualityassurance standards for all Microsoft products. Software Development Engineers (SDEs) are often referred to as Software Development. SDEs write the code that drives Microsoft products and upgrades. Very few teams in Microsoft are still using SDETs to do significant amount of manual testing. Manual testing is mainly outsourced. Actually, as early as in 2004, for example, most of the manual testing of MSN Explorer was outsourced. Think about it this way: it just doesn't make sense for test manager to spend their headcount (SDETs) on something can be easily outsourced.  Until 2005, Microso

Trim / Remove spaces in Xpath?

Image
If you are wondering how you can trim the spaces in your xpath, this is how: The normalize-space function strips leading and trailing white-space from a string, replaces sequences of white-space characters by a single space, and returns the resulting string. Example : Which one is better? //td[starts-with(normalize-space(),'Text to Trim')] //td[starts-with(normalize-space(text()),' Text to Trim ')] The second option is better as it targets at the specific nodes More string functions in XPATH: Functions Description starts-with( string1 ,  string2 ) Returns true if the first string starts with the second string. contains( string1 ,  string2 ) Returns true if the first string contains the second string. substring( string offset length ) Returns a section of the string. The section starts at  offset (which is a number), and is as long as the value provided at  length. substring-before( string1 ,  string2 ) Returns the part of  string1  up unti
