- Built a functional test automation framework based on WebDriver for automating tests for a web application, a REST API service written in Python, and a service application with HTTP and SMPP interfaces. Included integration tests in all three apps.
- Created an automated performance (load) test framework for a REST API service. Wrote a custom-made JMeter sampler (based on Cloudhopper Java library) for load-testing the SMPP server. Created a shell script used for collecting KPIs (key performance indicators) of the machines where services were run and a Java tool to merge all the KPI outputs into one aggregated CSV file.
- Conducted exploratory testing of RabbitMQ and Elasticsearch in order to validate if those were good and reliable enough to be used as parts of some products and services. Testing included both functional and performance testing.
