Experience

Building the Entire Test Automation Framework at nCrypt

As the first QA automation engineer hired at the company, I had the opportunity to build the test automation project from the ground up. I used Selenium WebDriver with Java, TestNG, and Maven. I incorporated Log4J for logging test steps and error stack trace to a log file, 我添加了ExtentReports，用于生成用户友好的HTML报告，以显示测试结果.

我自动化了前端web应用程序中所有关键和常用的工作流, 自动化套件在回归测试期间运行，以减少手工测试的时间和工作量. QA团队特别赞赏这样一个事实，即自动化测试取代了一些涉及数字计算和检查正确现金的最乏味和耗时的手动测试用例, bitcoin, and bitcoin cash balances in the customers' wallets within the application.

Building an API Test Suite to Test RESTful Web Services

在BCAA，我参与了一个需要web服务API测试的数据标记化项目. Since no one on my team had done API testing before, I took the initiative to build the test suite from scratch. 因为我们是一家Java公司，所以我使用REST Assured Java框架来测试REST API端点.

After creating the testing framework and the initial set of test cases, 我指导另一个测试人员学习REST服务和编写API测试的编程语法. The project was a success, and the entire test suite was run on a daily basis in Bamboo, our continuous integration tool.

Leading the QA Activities for a Brand-new Government Agile Project

我被一家政府机构聘为一个全新的敏捷项目的测试主管和QA自动化工程师. 该项目的目的是重新设计和重建内部网，使其能够作为员工的协作和知识共享平台.

After some discussions with the development team, 我们决定用Python构建测试自动化项目，因为它是大多数开发人员熟悉的语言. 我使用Selenium WebDriver从零开始构建测试自动化框架，并对开发人员在每个sprint中生成的所有新特性进行自动化测试.

In addition to building the entire test automation framework, I also mentored junior testers, set up, and configured test management and defect tracking systems, performed accessibility testing for the hearing-impaired, and created the test strategy document for submission to the senior management.

我们参与的敏捷项目为组织内的其他部门提供了一个开创性的例子, 并且我们经常让同事访问我们的办公室，了解我们如何使用敏捷方法以增量方式成功地交付我们的项目.

Serving as a Mentor in UBC's Computer Science Mentorship Program

Since 2006, 我一直志愿担任英属哥伦比亚大学计算机科学指导计划的导师. 这个项目可以让我回馈计算机科学系，同时为学生的课程和职业方向提供指导. Not only have I found this experience to be rewarding, I have also made some lifelong friends over the years.
