What is BDD?
Behavior Driven Development is a disciplined technique for building software in which the Product Owner, a Programmer, and a Tester collaborate on system behavior, also known as, acceptance criteria for the future that is about to be implemented.
Initially we had waterfall models, wherein the role of Development team starts after the requirement finalization, and after Development is completed, then comes into picture, the QA/Testing team.
Then Iterative and Agile models were introduced, where though the time reduced in which the builds were released, but the testing time given to Testers (Specifically Automation Testers) was not sufficient enough.
So there came in the concept of BDD, where we follow the shift left concept.
Biggest Challenge in software development is trying to understand the requirements of customers. BDD encourages creating a shared understanding and collaboration by writing simple, scenario based, single source specifications that business people can understand and quickly agree to provide clear tracebility.
Syntax in Gherkin is used as follows:
This was about BDD, but to make it successful, we will be using Devops.
Since customer satisfaction and our loyalty towards them is very important ,we use DevOps because it improves the way that a business delivers value to its customers, suppliers, and partners.
DevOps follow the concept of CICD – Continuous integration Continuous Development.
Example/Benefit of CICD: Let’s say a small portion of the software is developed, and the build is integrated on Jenkins, the testing team has test cases ready written in simple English format (Gherkin) as discussed in BDD section.
The manual testers would start testing the application after deployment on production like environment and the automation testers would start building there automation scripts. Bugs would be found and reported and automation scripts would be ready (for say 20 Test cases) .Now the second build revision is out, so when it comes to the test, the 20 test cases can be automated and need no manual testing.
This process helps early identification of bugs, less rework and early results
Automated Environment Provisioning
Testing In Devops Using Automated Environment Provisioning
There are many companies which use cloud services in which there would be systems available with different hardware configurations and with different combinations of software’s (SVN, Eclipse, Selenium, QTP etc).
These machines can be used for specific time and the company will have to pay for the usage hours.This would in turn reduce a large amount of hardware and software costs and will provide a good ROI.
Establishing and connecting all the service components to enable the service operation can be a complex project. This delays service delivery to the business and potentially results in errors that add to audit expenses. Automated Environment Provisioning ties together the components that make up the service to execute a complete end-to-end deployment of the service in a single, fully-automated process
AT&T and Cisco have developed a robust small cell solution for the home and home office: the AT&T Micro-Cell. The AT&T Micro-Cell provides cellular coverage indoors where you need it most. It connects to AT&T's network using existing broadband Internet service. With the AT&T Micro-Cell, customers receive improved cellular signal performance for both voice calls and cellular data applications.
Microcellular systems are typically used to provide low cost mobile phone systems in high-density environments such as large cities. There are 3G micro cell devices that expands the network for the particular areas like as a mall, a hotel, or a transportation hub. We can register multiple mobile numbers with that device.
For example : A mobile number “08956879510” is registered in the 3G micro cell device, and when that mobile device comes in the coverage of the 3G micro cell device network ,it will catch the network and can operate on it.
A microcell is a cell in a mobile phone network served by a low power cellular base station (tower), covering a limited area such as a mall, a hotel, or a transportation hub. A microcell uses power control to limit the radius of its coverage area.
A microcellular network is a radio network composed of microcells.
