I worked as a QA Engineer in the automation department. During my tenure I significantly contributed for the core automation framework development in Selenium/Java and functional automation in BDD. I was actively involved in development of utils, helper libraries, writing automation scenarios features for new UI functional changes and maintained regression testing.

Responsibilities:

Agile Scrum:

• Involved in daily standups, prioritising stories, product backlog grooming, sprint planning, story analysis for deriving tasks and estimating.
• Worked with various Agile teams for requirements analysis, test planning, automation and execution.

Automation Testing with BDD Cucumber Selenium WebDriver in Java:

• Developed new features implementation java code in the framework. Developed helper libraries, implemented steps, enhanced and maintained the framework with optimal, reusable, extendable and efficient approaches.
• Prepared UI test automation scenarios in Gherkin language for BDD with Cucumber in Java and grouped them for targeted runs of system, Integration, regression and component testing.
• Created scenarios in Gherkin language for BDD with Cucumber in Java. Utilised scenario, scenario outline with multi-level examples, data tables, parameterized data, tagging at various levels for generating  tests for specific scenarios sets, feature level, functionally based grouping, smoke, sanity and regression. 
• Implemented new steps in the  automation framework,  refactored existing code based on functional changes.
• Analysed cucumber scenarios execution report, debugged for root causes and applied fixes as required.
• Analysed DOM, style sheets, nodes to derive reliable relative xpath and CSS paths appropriately in order to make tests robust and not to break often due to changes.
• Selectors used are with a combination of ids, names, tags, attributes and values, regular expressions, custom attributes, traversing to parent and child nodes. 
• Prioritised regression tests with severity, priority and time to execute and plan story/sprint/release specific regression test suites. 
• Identified and updated regression test cases that will be impacted by the current story acceptance criteria and maintain traceability to requirements.
• Identified repeated code and transformed into reusable easy maintainable classes and methods.
• Wrote and maintained BDD feature files with regular expressions, steps files, runner files, JUnit tests, test suites, annotations, assertions.
• Used best practices to write helpers using Java interfaces, abstract methods, abstract classes, base and inherited classes and methods, constructors overloading and overriding, static variables, blocks and methods, encapsulation with getters and setters, typecasting, dynamic object type casting.
• Communicated with the design team, front-end team and java script developers to include reliable attributes and values, so that automation tests can be written well in advance before application is fully developed.
• Maintained selenium GitHub repository per project and committed automation code changes to story branches.
• Raised pull requests for review by developers, discuss and amend for best practices before merged to the main branch.
• Performed End-to-End testing of the software product, raised issues, followed QA process and more importantly was responsible to say –Go/No Go for a release.
• Utilised ‘Surefire’ and ‘Failsafe’ plugins for  parallel and multi browser executions. 
• Inorder to execute failed only scenarios of broader test suite, configured ‘Rerun’ plugin which saved substantial execution time during the regression.
• Used Selenium Grid for faster execution with multiple machines and browsers.

API Web Service Testing:  

• Implemented, enhanced/maintained existing code base for API calls automation in REST Assured Java.
• Executed automated scenarios for In-house and external API functionality for various REST requests of GET/POST/PUT/DELETE.

Database Testing:

• Wrote and executed SQL queries for CRUD on Mongo database loaded with data from various data sources and message systems.
• Analysed query results for constraints, unique and null values, schema changes validation, data types verification, index changes

Microservices and Docker:

• Tested various microservices application versions for specific changes. From the repository, deployed the images using Docker containers. Scaled up/down containers with required configurations, filtered and analysed logs for identifying issues and root causes. 

CI/CD with Jenkins:

• Configured various Jenkins jobs for sanity and regression tests in cross browsers to run on dev, test and pre productions staging environments.
• Based on development code changes and acceptance criteria, identified and triggered cascaded Jenkins jobs to run targeted test suites one after other. 
• Executed automated Jenkins driven tests successfully identified bugs and helped fix confirmation tests. This saved a lot of manual resources and gave quick feedback to developers.
• Jenkins generated automation test reports are communicated to the team and notified test coverage.

Debugging:

• Hands-on experience on Linux. Analysed logs, stack traces, http requests and responses, stack traces, DOM elements using inspectors and developer tools such as Firebug, Fire path CSS changes, URLs validity, REST requests and responses, ajax, cache details, content types and content sent and received, html tags and attribute values, panes, browser agents details, cookies, for java script, events triggering and communicate with developers for root cause analysis. 

Bug Reporting:

• Followed Defect/ Incident Life Cycle for reporting bugs in JIRA by including detailed description, steps to reproduce, screen shots, events video captures, user credentials, URLs, breadcrumbs, stack traces, timestamps, client and server logs, blocked tests and work around. 
• Found several bugs and did impact analysis for identifying the severity, priority, impact and likelihood and ensured any critical or major bugs are communicated as soon as possible for fix 
• Assisted developers to reproduce issues in their local environments and executed fix confirmation tests.
• Search reported bugs for duplication, if it was not previously reported, communicate with product owner and test lead to validate issue to report as bug.
• Participated in bug triaging meetings and included known bugs and work around in deployment notes for releases. 

Tools: Selenium/WebDriver in Java, Maven, Jenkins, IntelliJ, Git, VMs, Docker Containers, API REST Client, Postman, Firebug, Firepath, Selectors Hub, Mongo Db, Failsafe plugin, Surefire plugin, Grid.
