DevOps

About DevOps

DevOps is a set of practices that automatically integrate the processes between development team and  SQA, database or other related teams , so that a new  build can be tested, and released which in turns makes a software faster and more reliably. The term DevOps was formed by combining the words “development” and “operations” and signifies a cultural shift that bridges the gap between development and operation teams.  

As DevOps is intended to be a cross-functional mode of working, those who practice the methodology use different sets of tools rather than a single one. These tools are expected to fit into one or more of the following categories, reflective of key aspects of the development and delivery process: 

  1. Coding – code development and review, source code management tools, code merging.
  2. Building – continuous integration tools, build status.
  3. Testing – continuous testing tools that provide quick and timely feedback on business risks.
  4. Packaging – artifact repository, application pre-deployment staging.
  5. Releasing – change management, release approvals, release automation.
  6. Configuring – infrastructure configuration and management, infrastructure as code tools.
  7. Monitoring – applications performance monitoring, end-user experience.

Some categories are more essential in a DevOps toolchain than others; especially continuous integration (e.g. Jenkins, Gitlab, Bitbucket pipelines) and infrastructure as code (e.g., Terraform, Ansible, Puppet).

Agile Scrum Development Methodology

About Agile Scrum Development

Scrum is a framework within which people can address complex adaptive problems, while productively and creatively delivering products of the highest possible value.

Scrum itself is a simple framework for effective team collaboration on complex products.  Scrum co-creators Ken Schwaber and Jeff Sutherland have written The Scrum Guide to explain Scrum clearly and succinctly.  This Guide contains the definition of Scrum. This definition consists of Scrum’s roles, events, artifacts, and the rules that bind them together.

Scrum is:

Lightweight

Simple to understand

Difficult to master

 

Scrum is simple.  It is the opposite of a big collection of interwoven mandatory components. Scrum is not a methodology. Scrum implements the scientific method of empiricism. Scrum replaces a programmed algorithmic approach with a heuristic one, with respect for people and self-organization to deal with unpredictability and solving complex problems.  The below graphic represents Scrum in Action as described by Ken Schwaber and Jeff Sutherland in their book Software in 30 Days taking us from planning through software delivery. 

 

The Scrum Team consists of a Product Owner, the Development Team, and a Scrum Master. Scrum Teams are self-organizing and cross-functional. Self-organizing teams choose how best to accomplish their work, rather than being directed by others outside the team. Cross-functional teams have all competencies needed to accomplish the work without depending on others not part of the team. The team model in Scrum is designed to optimize flexibility, creativity, and productivity.

Jmeter

About JMeter

Apache JMeter is an Apache project that can be used as a load testing tool for analyzing and measuring the performance of a variety of services, with a focus on web applications

JMeter can be used as a unit-test tool for JDBC database connections, FTP, LDAP, web services, JMS, HTTP, generic TCP connections and OS-native processes. One can also configure JMeter as a monitor, although this is typically used as a basic monitoring solution rather than advanced monitoring. It can be used for some functional testing as well. Additionally, JMeter supports integration with Selenium, which allows it to run automation scripts alongside performance or load tests.

JMeter supports variable parameterization, assertions (response validation), per-thread cookies, configuration variables and a variety of reports.

SQL is a domain-specific language used in programming and designed for managing data held in a relational database management system (RDBMS). It is particularly useful in handling structured data, i.e. data incorporating relations among entities and variables.SQL (pronounced “ess-que-el”) stands for Structured Query Language. SQL is used to communicate with a database. According to ANSI (American National Standards Institute), it is the standard language for relational database management systems.

You will learn SQL as part of Selenium Webdriver which will boost your testing capacity. As a professional, you will be able to demonstrate your capability your testing approach applying this structured language. It will lead you to work independently in this arena.
