Facebook Infer - Detect bugs before you ship



What is Infer?
An Opensource tool to detect bugs in Android and iOS apps before they ship - http://fbinfer.com/

Documentation (Getting Started Guide) - http://fbinfer.com/docs/getting-started.html

Quotes from "Peter O’Hearn" - engineering manager at Facebook
  • When you have to write a software test, often you are going after a specific bug. That means you’ll need to exercise all of the funny cases that will get you to that bug. Static analysis allows you to execute the code symbolically
  • It’s important to know that while things like Infer have made us faster and more successful, they’re not pieces of the Facebook competitive differentiator
  • another huge benefit of open source is in recruiting. By showing you can open source stuff if you built it at Facebook, then you get excellent, independent engineers who don’t require as much ramp up time, since they’re used to working on these open source projects. So there’s far less training.

Software Testing @ Microsoft

Image
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
