Kubernetes Training in BTM Bangalore

What are kubernetes?

Kubernete is an open-source architecture that acts as a container to balance the system. Kubernetes provides containers to allow the control automation of the tasks. Developers depend on those containers to initialise the tasks, but to control the life cycle of containers there are some arrangements required for the system.

It was discovered by Joe Beda, Brendan Burns, and Craig Mcluckie, later they collaborated with other Google engineers and were inspired by Google's Borg. kubernete open-source system disputes the containers to manage logic in a simple way. They indicated it later to the  CNCF(Cloud Native Computing Foundation).

Why learn Kubernetes?

Objects of Kubernetes convey the applications range according to the CPU memory oor other kinds of metrics. It can be worked in any kind of container that facilitates the Open Container Initiative(OCI), which leads the developer to work with different containers utilising lesser resources.

Applications that are containerised can promote new features of the development, and Kubernetes are developed to work with Dockers, it also provides a higher level of operation than Docker including Docker Swarm. It scales and loads the balance of management and also discovers the services. The containers are separated from each other till the time when the developer chooses to connect them. It allows many flexible applications without any complicated interference.

Kubernetes is a large part of DevOps that allows clear information for containers. Kubernete APIs have the capability to handle complexities. 

It is a better choice for managing modern container deployments in an efficient, flexible, and business-friendly way.

Features of Kubernetes 

• It allows the management of large amounts of containers in a single place.
• It is an open-source architecture that facilitates the use of on-premises, hybrid, or public cloud infrastructure. 
• It allows automating new features of the application and restoring the application.
• Capability of running containerised applications of any scale without any break

What is Docker ? its working mechanism, tools and components.

What is Docker?

Docker is a container in which the containers create, manage, deploy and visualize applications in the software environment. The implementation of these containers on the common operating system with the help of some allied tools. Docker container developed in 2013. 

Docker container is an independent, executable and lightweight container that facilitates to run an application. Its libraries, tools, components, and runtime make the execution of an application easy and efficient. It is also known as software space where the applications are tested and developed quickly. 

Cloud services manage container services and the life cycle of containers. The runtime mechanism of containers is controlled by container services. Container services help to speed up, automate, simplify the development of application and deployment lifecycle.

How does it work?

Docker creates, manages, and operates containers. The operating system provides access to container technology: A container contains all of the libraries, configuration files, dependencies, and other components and parameters required for the application service or function to work. One underlying operating system is shared by all containers. Containers that travel between Docker environments with the same OS run without changes since Docker images contain all of the dependencies needed to execute code within a container.

To run several containers on the same OS, Docker leverages resource isolation in the OS kernel. Virtual machines (VMs), on the other hand, enclose a whole operating system with executable code on top of an abstraction layer of physical hardware resources.

Docker was originally designed to run on Linux, but it has now expanded to include support for non-Linux operating systems such as Microsoft Windows and Apple OS X. There are Docker versions for Amazon Web Services (AWS) and Microsoft Azure.

Docker tools and components 

• Docker Community Edition is free and open source, but Docker Enterprise Edition is a for-profit offering from Docker Inc. Docker is a collection of components and tools for building, testing, and managing containers.
• The Docker Engine is the underlying technology that manages the activities and workflows associated with developing container-based applications. The engine provides a daemon process that hosts images, containers, networks, and storage volumes on the server side. Users can interact with the daemon via the Docker application programming interface via a client-side command-line interface (CLI). Docker files are the names for the containers generated by Docker. Docker Compose files specify how a Docker container's components are put together.
• Docker Hub is a software-as-a-service technology that allows users to publish and distribute container-based programmes via a central repository. More than 100,000 publicly accessible apps, as well as public and private container registries, are available through the service.

Trusted Registry, like Hub, is a repository that provides an additional layer of control and ownership over container image storage and delivery.

• Docker Engine's swarm mode allows cluster load balancing for Docker. Numerous Docker host resources are pooled together to act as if they were one, allowing customers to scale up container deployments to multiple hosts fast.

The Universal Control Plane is a unified cluster and application administration interface that is accessible over the web.

Compose is a command-line utility for configuring multi-container application services, viewing container statuses, streaming log output, and running single-instance processes.

Content Trust is a security solution that uses user signatures and image metadata to validate the integrity of distant Docker registries.

Selenium Testing Training in Bangalore

Selenium is an open-source framework and portable tool that is utilized for mechanizing the tests directed on internet browsers. It is just utilized for testing web applications, for example, Shopping Carts, Email Programs like Gmail, Yahoo.

Testing done by utilizing Selenium is regularly known  as Selenium Testing.

Selenium isn't only a solitary tool, as it is a group of software and each tool has various instances of testing.

Selenium was presented by Jason Huggins in 2004. Jason Huggins is an Engineer at Thoughtworks. He was taking care of his responsibilities on some web applications and he suddenly required testing.

He understood that ordinary Manual Testing (used to distinguish bugs, issues, and imperfections in programming) of their application was going to be increasingly ineffectual.

He made a JavaScript Program that would control the program's activity. Also he named the program "JavaScriptTestRunner" and later he made JavaScriptTestRunner as an Open Source that was subsequently renamed as Selenium core.

 What are the tools in selenium?

1.    Selenium integrated development environment

2.    Selenium remote control

3.    Selenium web driver

4.    Selenium grid

Selenium IDE is implemented as a firefox extension that offers record and functionality on test Script and provides the tester to create recorded scripts in many types such as HTML,Java, Ruby, Python, etc.

Selenium RC provides the testers to create automated web application tests with support of any programming languages. It also includes HTTP proxy servers that enable the browser to understand that web applications are tested and come from proxy servers.

Selenium web driver offers programming interface to create test cases, and the test scripts are created according to the identification of web elements on the web pages then executes the action that can be performed on the web elements. It directly conveys with the web browser. Selenium web driver includes HTML unit driver, opera driver, safari driver, etc.

 Selenium grid is the most important component of selenium that run and compiles the test cases in a parallel environment on a different operating system or browser

 Features of Selenium

●     Selenium supports multiple browsers such as google chrome, safari, firefox by executing simple commands.

 

●     Selenium supports multiple programming languages such as Java, Python, C#, Perl, etc.

 

●     It is speed in execution that directly conveys with the browser without the need of an intermediate server.

 

●     Easy to identify and it's easy for locators in webdriver helps in finding web elements in the website. It is a great advantage for the testers to implement.

 

●     It is an open-source and portable framework that can work on different operating systems like Linux, Mac, etc.

 

●     It reduces time and increases efficiency that is used widely for web development.

 

●     Selenium promotes continuous integration and continuous delivery.

 

Limitations of Selenium

●     It is used for only testing web applications, not software.

●     It is not accurate in handling dynamic web applications.

●     It faces some problems while handling pop-ups and frames.

●     There is absent of test integration tool for test management

●     Huge skillset is required for automating test tools.

Why use Selenium?

Selenium motivates testers to compose a script to create content in one programming language and run (re-use) the same test scripts on different platforms. WebDriver is turning out to be important for the W3C standard for all programs, and hence creating programs that will naturally uphold Selenium. The interesting part of this test automation tool is that the testers in testing UI modules offer an enormous set of choices to test, think about the outcomes and check to assume that they are in agreement with the normal application conduct or not.

There are some reasons why we use the Selenium framework for web application development such as transparency, platform independence, visibility in end-to-end testing, and continuous integration efforts.

Manual Testing Training in Bangalore

Manual testing is known as a software testing process that executes test cases without the use of any tools. According to the end user’s point of view it executes the test cases manually. It checks the working condition of an application correctly and implements the complete software application effectively.

 Manual testing is the fundamental process that can correct both the visible and hidden defects of software applications accurately. Manual testing is very important for the all new developed software before automation  time and effort is essential for manual testing. It provides bug free software. Manual is an essential component for the testing in software development.

Although manual testing is required for the newly developed software. It checks the features of software working properly. It ensures that all are created and processed properly.

 Types of Manual testing

Manual testing keeps the software development error-free. There are various types to ensure error-free software development.

 1)   Black box testing:

It is the technique of testing software development without seeing internal code structure. Hence the developers don't want to know about the internal code structure. It ensures if the software matches its specification and requirements given by users. Black box testing ensures the inputs and output application without the consideration of internal structure.

 2)   White Box Testing

It  is exactly opposite of black-box testing. To perform manual testing internal structure, codebase knowledge is required, in this type it defines code visibility for the manual testers.

White box testing used to define the flow of input and output instead of focusing on the functional needs of the application. It is used to improve the software application design and usability that strengthens its security.

3)   Exploratory testing

Exploratory testing is a kind of Manual testing in which the testers don't want to create test cases in an advanced way. It is used to create out-of-box test cases and execute the test cases quickly.

The testers have the freedom and responsibility to introduce the continuous design and execution of testion features.

It helps the testers to escape from the predefined test cases and provides learning, investigation and discovery of the application in learning.

Difference between Manual andAutomation testing

Manual testing requires human action while automation testing requires machines. Manual testing is suitable for user interface and user experience.

Automation testing is suitable for stable systems that promote lesser bugs, it is mostly used for regression testing and performance testing. Testing tools like selenium and Jmeter are commonly used.

 Pros

●     Accurate

●     Provides human insight

●     Adaptable

●     Saves money

Cons

●     It provides heavy resources

●     It is not always suitable

●     Potential for errors

●     It is not reusable

How Manual testing is performed?

❖   It is necessary to understand the project requirement, understand the behavior of software, and what should be tested.

❖   Prepare test cases after the understanding of project requirements and should implement the test case in order to provide error-free software application.

❖   Report the bugs once the bugs are identified, again execute failed test cases to verify they pass.

Why Manual Testing?

Manual testing is based on human perspective, the usability and look,feel of the application can be implemented by humans.

Manual check consistently gives a more extensive point of view of the general application. As the human mind will forever be in an exploratory structure, rather than a coding system that executes similar advances each time. In this way, it will give more extensive inclusion for the system validationAnother situation where manual testing is required is the situation usability testing.

 We perform usability testing to assess how helpful, proficient, and easy to understand the item has ended up being for the end clients. For this appraisal, we require the most elevated manual mediation and can't depend on instruments to survey it for us. So to assess the item according to the end-client perspective, we decide on manual testing.
