Agile Model shows an iterative and incremental approach. This approach breaks the product into small incremental units to provide iterations. Then each iteration involves steps like Planning, Requirement Analysis, Design, Coding, Unit Testing, Acceptance Testing, etc. This approach also allows continuous interaction with the customer for their feedback and corrections in the requirements at regular intervals. Agility is flexibility, it is a state of dynamic, adapted to the specific circumstances.
Agile Testing can begin at the start of the project with continuous integration between development and testing. Agile Testing is not sequential (in the sense it’s executed only after coding phase) but continuous.
An agile team works as a single team towards a common objective of achieving Quality. Agile Testing has shorter time frames called iterations (say from 1 to 4 weeks). This methodology is also called release, or delivery driven approach since it gives a better prediction on the workable products in short duration of time.
The agile test plan includes types of testing done in that iteration like test data requirements, infrastructure, test environments, and test results. Typical test plans in agile includes,
Agile testing life cycle spans through four stages, which are explained as follows.
The following steps are set to achieve in Iteration 0
The second phase of testing is Construction Iterations, most of the testing occurs during this phase. This phase is observed as a set of iterations to build an increment of the solution. To do that, within each iteration, the team implements a hybrid of practices from XP, Scrum, Agile modeling, and agile data and so on.
The goal of “Release, End Game” is to deploy your system successfully into production. The activities include in this phase are a training of end users, support people and operational people. Also, it includes marketing of the product release, back-up & restoration, finalization of system and user documentation.
After the release stage, the product will move to the production stage.
The agile testing quadrants separate the whole process in four Quadrants and help to understand how agile testing is performed.
a) Agile Quadrant I– The internal code quality is the focus in this quadrant, and it consists of test cases which are technology driven and are implemented to support the team, it includes
b) Agile Quadrant II– It contains test cases that are business driven and are implemented to support the team. This Quadrant focuses on the requirements. The kind of test performed in this phase is
c) Agile Quadrant III– This quadrant provides feedback to quadrants one and two. The test cases can be used as the basis to perform automation testing. In this quadrant, many rounds of iteration reviews are carried out which builds confidence in the product. The kind of testing done in this quadrant is
d) Agile Quadrant IV– This quadrant concentrates on the non-functional requirements such as performance, security, stability, etc. With the help of this quadrant, the application is made to deliver the non-functional qualities and expected value.
Agile testing involves testing as early as possible in the software development lifecycle. It demands high customer involvement and testing code as soon as it becomes available. The code should be stable enough to take it to system testing. Extensive regression testing can be done to make sure that the bugs are fixed and tested.
Businesses and organizations are moving their workload to the cloud for better agility, performance, and security. Cloud computing is the bellwether of hosting applications and databases to improve the overall efficiency of business processes. The disparity between the on-premise workload and cloud environment workload often results in businesses migrating the workload to the cloud. Cloud technology shows impeccable growth contributing to the adoption of cloud-based computing across many businesses and organizations.
Centaurus, a next-generation cloud for the telecom sector, is an open-source project for building cloud infrastructure platform that can be used to build and manage public or private clouds, edge computing, and edge device datacenter. It is a solution to address key challenges of large-scale clouds such as system scalability, resource efficiency, multi-tenancy, edge computing, and the native support for the fast-growing modern workloads such as containers and serverless functions. Centaurus helps in creating multiple nodes, managing infrastructure, containerizing the environment, managing the pods, and many more.
Cloud computing is picking up the pace replacing the traditional methods of storing the data, accessing, and running the applications. Cloud migration is the process to shift the existing data, applications, and other business elements from data centers or one cloud to other cloud environments for better scaling. Organizations are shifting their businesses on cloud for more speed and agility. Migration to cloud gives the organization limitless computing resources.
Click2Cloud support enterprises throughout their cloud infrastructure deployment process and empowers them with private cloud offerings, a cloud framework for compute, storage, and network services. To get the benefit of hybrid cloud and Edge computing an enterprise can accelerate the use of OpenStack, Apsara Stack, and Azure Stack services to transform technologies into cloud and deep industry growth to deliver abiding value.
This blog will give you a complete understanding on billing, budget, and cloud cost optimization. Cloud cost management is as important as knowing your bills. It is important to know your cloud spends and which cloud offers you a good service at minimal costs. Click2Cloud also offers you a semi-automated assessment platform “ CloudsIntel” to support you with assessment and migration plan
