Want to Performance test your web Applications? Then you should know about Apache JMeter.

What is Apache JMeter?

 It is a 100% pure Java application and Open Source testing software .It was designed for  load, stress, functional, performance testing.  It requires JDK 5 or higher.

What is performance testing ?

 Performance testing is the process of determining the speed or effectiveness of a computer, network, Software program or device. In this process involve quantitative tests done in a lab, such as measuring the response time or the number of MIPS (millions of instructions per second) at which a system functions. Qualitative attributes such as reliability, scalability and interoperability may also be evaluated. Performance testing is often done in conjunction with stress testing.

Heard about Node.js and Express but are confused where to start? Well, here you can find 3 easy steps to create and run Express application in Node.js on a Mac OS.

 How do you know what tool to choose? JIRA, VersionOne, Rally, DAD, LeanKit... the list goes on.

As a product owner, I am constantly challenged with writing user stories that meet my stakeholder needs. A key deliverable from a Product Owner is having user stories with crisp acceptance criteria. Having clear acceptance criteria enables the scrum team’s ability to deliver high-quality software. It also enables the team to make commitments toward sprint goals while ensuring that the business is getting high value deliverables based on the decomposition of the highest priority epics. The challenge in writing good user stories is always the amount of details to add to a user story. A good user story should have enough details to understand the business intent, the user roles, the goal and the depth so that the team can understand it to produce a workable prototype or software and the business can understand it.

Why Sync Spaces?

Contentful provides spaces to group related resources into one repository. The content from these spaces can then be retrieved using Contentful’s Content Delivery APIs. In situations where development is occurring on a website while a live (production) website is available and both are using the same space, there is a danger that development changes will be visible on the live website. To avoid running into such situations, it is desirable to have separate spaces for development and production and have a mechanism to sync these spaces periodically in a controlled environment.

Challenges While Syncing Spaces

There are some sync tools currently out there that provide a mechanism to sync from one space to another. However, these tools have limitations:

1. Most of these sync tools are command-line based.
2. They don’t provide a mechanism for the user to know the differences between the spaces and accept the changes for synchronization.
3. They fail to modify embedded URLs properly (to the Media in the space) within a Content.

In our experience, the embedded URL issue (#3) has caused us some major headaches.  After the sync process, this leaves the Content in the production space pointing at the Media in development space. Not a good situation!

But where is the system documentation?

The CI [continuous integration] pitfall to utilizing Git and Gerrit for code review.

We developers live in an object oriented world where data is represented as objects in our applications. However, these applications often end up saving their data in SQL databases which are relational, not object oriented. This often causes translation errors and could cost you and your team significant time tracing and debugging. Understanding keys, relationships, and cardinality are essential skills for any developer to be able to create and maintain reliable, consistent, and efficient applications by being able to create and read data models and spot potential problems before they become major bugs.

If you are familiar with open-source Jenkins, you understand that it is an award-winning continuous integration and deployment tool for a reason. It’s growing ecosystem of plugins has taken Jenkins to the next level providing extended features and added functionality.

However, an integral part of replicating your software delivery workflow is the ability to represent your delivery model visually while automating the process; with Enterprise Jenkins, you can completely re-write the script pun intended to accomplish this through the Pipeline Plugin.
