QA Testing for a Flutter Web Application

As a QA engineer, I ensured the Repoze application's quality by creating and documenting the test plan, executing and documenting the tests, researching test tools for end-to-end testing, and providing status updates from testing at the end of each sprint.

1. Test Plan Development – I created a comprehensive test plan for the application, which I documented in Confluence. The test plan included manual and automated testing scenarios.
2. Testing Execution – I implemented and documented the test plan to ensure it covered all the application's functional and non-functional requirements. I performed sprint testing, primarily manual testing, to ensure that the application met the acceptance criteria defined in the user stories.
3. Researching Test Tools – I researched test tools for end-to-end testing and implemented a POC using a flutter_driver that was integrated with GitHub Actions.
4. Status Updates – I created status updates at the end of each sprint to report on the testing progress and provide feedback on the application's overall quality.

Jenkins CI Setup and Chrome Extension Automation

As a QA automation consultant, my primary task was to help the customer's QA team set up a CI process for their local tests. To achieve this, I configured Jenkins CI to run tests, generate test reports, and post results on Slack, making it easier for the team to monitor test results and quickly identify any issues.

Additionally, I was tasked to create a POC to automate the testing of a Chrome extension. To achieve this, I developed a script that built and installed the extension into Chrome. I then implemented sample tests using the WebdriverIO framework, which the client was already using.

As part of my final deliverables, I also created documentation that explained the Jenkins setup and the Chrome extension automation process. This documentation served as a reference for the customer's QA team, helping them maintain and troubleshoot the automation processes as needed.

Overall, this project allowed me to showcase my expertise in QA automation and my ability to work closely with clients to identify their specific needs and provide effective solutions.

QA Testing for an iOS App Implemented with React Native

As a QA engineer, my primary task was creating a comprehensive test strategy and test plan for an iOS app implemented with React Native. This involved thoroughly analyzing the application's requirements, identifying potential risks, and devising a detailed testing plan to ensure the app met quality and performance standards.

Once the testing plan was in place, my secondary tasks included sprint, user stories, and regression testing for release. During these tasks, I used Jira to report any issues found. Then at the end of each sprint, I created a quality report with bug statistics to present to the client.

To further enhance the testing process, I implemented mobile UI end-to-end tests using the Maestro framework. I also implemented REST API tests using JavaScript, Jest, and the Supertest library. The test automation saved us time and effort during the testing process, provided more comprehensive testing coverage, and helped identify potential issues earlier in the development process.
