Migrating an existing project to a new git repo

Image
Create a new repositoryon GitHub. To avoid errors, do not initialize the new repository withREADME, license, orgitignorefiles. You can add these files after your project has been pushed to GitHub. Open Git Bash. Change the current working directory to your local project. Initialize the local directory as a Git repository. git init Add the files in your new local repository. This stages them for the first commit. git add .# Adds the files in the local repository and stages them for commit. To unstage a file, use 'git reset HEAD YOUR-FILE'. Commit the files that you've staged in your local repository. git commit -m "First commit"

Coypu - magic for Selenium

Image
Coypu is an advanced wrapper for Selenium. Coypu supports browser automation in .Net to help make tests readable, robust, fast to write and less tightly coupled to the UI.
If your tests are littered with sleeps, retries, complex XPath expressions and IDs dug out of the source with FireBug then Coypu might help.

As coypu has evolved over a period of time, the tool understood the pain points of selenium testers, hence you don’t really have to think of
Creating browser object and working with different browsersFinding controls by complex Xpaths, CSS etc Coypu isA robust wrapper for browser automation tools on .Net, such as Selenium WebDriver that eases automating ajax-heavy websites and reduces coupling to the HTML, CSS & JSA more intuitive DSL for interacting with the browser in the way a human being would, inspired by the ruby framework Capybara - http://github.com/jnicklas/capybara

Git Tricks - Commit message

Image
## I am using git. I did a pull from a remote repo and got an error message: "please enter a commit message to explain why this merge is necessary,especially if it merges an updated upstream into a topic branch."
I try to type a message and press enter but nothing happens.

It's not a Git error message, it's the editor as git uses your default editor.

To solve this:

press "i"
write your merge message
press "esc"
write ":wq"
then press enter

Error

The "TechTalk.SpecFlow.Tools.MsBuild.GenerateAll" task could not be loaded from the assembly ~\packages\SpecFlow.Plus.Excel.1.2.0\tools\specflow.exe.
Could not load file or assembly 'Microsoft.Build.Utilities.v3.5, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies.
The system cannot find the file specified.
Confirm that the declaration is correct, that the assembly and all its dependencies are available, and that the task contains a public class that implements Microsoft.Build.Framework.ITask

Solution:

So I decided to get to specflow.exe from here

This particular app requires the older .NET Framework 3.0. Although the newer .NET Frameworks will try to emulate backwards compatibility, and developers can code to allow different versions, specflow insisted on hav…

Serverless Testing - AWS Lambda

Image
Let's start with what is Serverless Framework?

Build applications comprised of microservices that run in response to events, auto-scale for you, and only charge you when they run. This lowers the total cost of maintaining your apps, enabling you to build more logic, faster.
The Serverless Framework helps you develop and deploy your AWS Lambda functions, along with the AWS infrastructure resources they require. It's a CLI that offers structure, automation and best practices out-of-the-box, allowing you to focus on building sophisticated, event-driven, serverless architectures, comprised of Functions and Events.It manages your code as well as your infrastructureIt supports multiple languages (Node.js, Python, Java, and more) AWS Lambda is a compute service that lets you run code without provisioning or managing servers. You can also build serverless applications composed of functions that are triggered by events and automatically deploy them using AWS CodePipeline and AWS CodeB…

GitHub - Embed or add images to .md files

Image
If you are looking to insert images in your .md file on github there is no direct way.

Here is the trick to do get an embedded image

In most cases your CDN assets do not, however, need to be version controlled. And while Amazon CloudFront or Akamai offer great CDN solutions, such approaches
(a) physically separates your repository from your images, and
(b) becomes an upload and maintenance PITA when you have a simple set of static assets.

So the summary advice is:

Do not try to add your images to the repository itself and then use a reference to a raw path.Do not worry about deploying your static images and other file attachments to Amazon CloudFront or Akamai
Click on Issues tab: Create an issue with title appropriate to the context of your images Create a new issue You can drag-n-drop 1 or more images onto the Leave a Comment box and those files will be instantly uploaded to the hidden GitHub asset manager. After each upload, GitHub will update the text the markdown link to the imag…

Problem: I created this confluence page that acts as a single source of truth for the community.
I wan't sure who was reading or looking at this page.
Also helps me when I roll out comms  to make sure the right number of people and the appropriate people has seen it.

Solution:
You could enable the Confluence Usage Stats plugin and you would be able to see anonymous viewing stats for all pages: https://confluence.atlassian.com/display/DOC/View+Space+Activity
OR

You could install the viewtracker plugin: https://marketplace.atlassian.com/plugins/ch.bitvoodoo.confluence.plugins.viewtracker

Mock the backend using Postman

Postman has developed a new mock service to enable teams to simulate a backend server. Front-end developers can simulate each endpoint in a Postman Collection (and corresponding environment) to view the potential responses, without actually spinning up a back end. Simulate a back end with Postman's mock service Throughout the development process, delays on the front end or back end can hold up dependent teams from completing their work efficiently. Some API engineers already use Postman to work on endpoints without relying on a front-end UI to simulate API requests. Now, Postman has developed a new mock service to enable teams to simulate a backend server.

Here is also agood repository that uses postman collections demonstrating a variety of use cases for all REST and Platform Extension APIs:

Facebook is building brain-computer interfaces for typing and skin-hearing


Facebook is building brain-computer interfaces for typing and skin-hearing Today at F8, Facebook revealed it has a team of 60 engineers working on building a brain-computer interface that will let you type with just your mind without invasive implants. The team plans to use optical imaging to scan your brain a hundred times per second to detect you speaking silently in your head, and translate it into text.

This week - Programming Turns 70

Image
April 12th, 1947: ENIAC, the world's first general-purpose programmable electronic computer, ran the first code written in the modern paradigm, marking the birth of computer programming as a profession.

This first test code ran computations for the hydrogen bomb.
ENIAC could perform complex coded operations like loops, seen today in languages like JavaScript, Ruby and Python.

These first professional programmers were all WOMEN, a fact that took 50 years to be recognised.
Coding ENIAC to solve a single problem would take weeks. Today, you can build a website in a matter of hours!

What is test sharding?

Test sharding allows you to evenly divide up your tests into groups. The shard index is which "percentage" group you are running.

How the groups are divided is arbitrary as the point of sharding is to parallelize your tests.
Generally used in the context of android:

Here is the code that shows test sharding for android devices:
androidtestlib/src/com/android/test/runner/TestRequestBuilder.java - platform/frameworks/testing - Git at Google android / platform / frameworks / testing / 2fe8aed7542ee05ce504d69656475d1948e9c5b2 / . / androidtestlib / src / com / android / test / runner / TestRequestBuilder.java
Another example of test sharding:

Test sharding manually with ADBTest sharding using an existing framework: Spoon
Another context of where you would hear this term is mongodb:

The best way to understand what is Machine Learning

This is probably one of the best single page website that could explain what is Machine Learning using interactive visualizations:


A visual introduction to machine learning Let's revisit the 73-m elevation boundary proposed previously to see how we can improve upon our intuition. Clearly, this requires a different perspective. By transforming our visualization into a histogram, we can better see how frequently homes appear at each elevation.

Machine Learning in the Test Automation space?

Image
For those of you who know me I have been exploring and talking about Machine Learning a lot these days. (Blame it on one of the meetups I had been to)

Let's explore the what and how of ML:
What is it?

Machine learning is the subfield of computer science that gives computers the ability to learn without being explicitly programmed - Arthur Samuel, 1959

Evolved from the study of pattern recognition and computational learning theory in artificial intelligence, machine learning explores the study and construction of algorithms that can learn from and make predictions on data

Machine learning is the study of computer algorithms that improve automatically through experience - Tom Mitchell
