Dependency Management and Maven

Maven is a great and mature build automation tool. There is always a solution on almost everything. The main case you might stumble on organization projects is dependency management. Instead of each project having its own dependencies you want a centralized way to inherit those dependencies.

In those cases, you declare on the parent prom the managed dependencies. In my example, I just want to include the Akka stream dependencies.

Getting Started With Maven For Selenium Testing

While working on a project for test automation, you’d require all the Selenium dependencies associated with it. Usually these dependencies are downloaded and upgraded manually throughout the project lifecycle, but as the project gets bigger, managing dependencies can be quite challenging. This is why you need build automation tools, such as Maven, to handle them automatically.

Maven can be more specifically defined as a software project management tool that uses the concepts of project object model (POM). It enables the user to create an initial folder structure, perform compilation and testing, and then package and deploy the final product. It efficiently cuts down several steps followed in the build process and makes the build a one step process.

In this Selenium Maven tutorial, I’ll explain what Maven is and why Maven is important as a build automation tool. Further, I’ll show you how to install Maven for your Selenium test automation projects and run your first project in this Selenium Maven tutorial. In case you aren’t familiar with Selenium, you can refer to this detailed web page on, what is Selenium?

Why Use Maven?

Maven plays a crucial role in managing a project lifecycle, which typically includes validation, code generation, compilation, testing, packaging and much more. It is a software build tool that works in phases rather than tasks (as in the case of Ant). It is basically used to manage the life cycle of a project. Maven makes the build management process much easier, as you’ll only need to specify the dependencies in the pom.xml files and Maven will take care of the rest!

Some of the key reasons Maven is used are:

• It simplifies the build process and provides a uniform system
• It handles compilation, distribution, dependency management and other tasks efficiently.
• It increases reusability.
• It reduces steps, like adding jar files to the project library, building reports, executing JUnit test cases, creating jar/war/ear files for deployment.
• It has a repository which is centralized that manages jar files.

Now that we know why to use Maven, let’s explore a bigger question in this Selenium Maven tutorial, What is Maven?

What Is Maven?

By now, you already have the idea that Maven is a build automation tool which is used to manage the project dependency and the whole project lifecycle. Maven is built by Apache Software Foundation and is used majorly for Java projects. It was initially developed to make the build process of the Jakarta Turbine Project much simpler and is now widely used to make build processes easy and uniform.

Maven can be more specifically defined as a software project management tool that uses the concepts of project object model (POM). It enables the user to create initial folder structure, perform compilation and testing and then package and deploy the final product. It efficiently cuts down several steps followed in the build process and rather makes the build a one step process.

How to Install and Correct Dependencies Issues in Ubuntu

What is a Dependency?
A dependency is defined as a file, component, or software package that a program needs to work correctly. Almost every software package we install depends on another piece of code or software to work as expected. Because the overall theme of Linux has always been to have a program do one specific thing, and do it well, many software titles utilize other pieces of software to run correctly.

Introduction
Let’s review what dependencies are and why they are required. We all have, at one point or another, most certainly seen a message from our system when we were installing software regarding “missing dependencies.” This error denotes that a required part of the software package is outdated, unavailable or missing. Let’s review how to address those issues when we come across them on Ubuntu.

Way to find out if DNS is down or your instance with python

DNS-PING

Way to find out if DNS is down or your instance.

Problem: At times it happens that DNS provider services of a website URL is down and so to reduce response time by not diagnosing the infrastructure and informing the user to check with DNS provider.

Functionality: Lambda in python pings the URL to be monitored and fetch the response. If the response code is anything other than 200 it triggers CloudWatch event and send SNS to user.

How to Run the Script : Create a Lambda function called “DNS-PING” the run-time version Python 3.6 and above by using the attach code. Creation of the Lambda function will in turn create CloudWatch Logs groups for its logging. Lamda can be call every 5 mins or as per your business requirement.
