- Customer: Landis + GYR (UK)Position: Embedded Automation Test Engineer using Python.
- Testing Automation Tool: ATS (with Python Interface), NI Test Stand
- Dedicated professional with 2 years of experience and working on automating manual work using python and SMETS5 compliant smart meters. I worked on parsing of html reports which is generated after test case execution and update the results to CSV file and excel using python modules (pandas).
- Testing Smart Meter software functionality which includes critical features like Security Credentials, tariffs / billings, charges, payment modes, Tamper, Special days Scheduling, Auxiliary Controllers, OTA upgrade/downgrade features to confirm that the product meets marketing and customer requirements (SMETS2, GBCS and Utilities Spec).
- Had good experience in writing the HLTA (high level test approaches) and LLTA (low level test approaches) based on the requirement. And also implementing those approaches in python (PYATS framework).
- Testing of implemented test cases by setting up the proper hardware environment.
- Created some power bi dash boards by extracting data from Microsoft Team foundation server for client presentations. Implemented a python script for fetching data related to user stories, bugs.
- Automated updating of CSV files which is used for creating batch files (stores the commands to be executed in serial order) to improve the accuracy of execution and time reduction..
- Automated build triggering in Jenkins using python .I also worked on creating new jobs, reconfigure the existing jobs, triggering the build generation, reading the existing job list using python by accessing Jenkins rest API.
- Implemented a python script that will extract data from Azure Devops server by using the TFS query , the purpose of this script is to remind the team members that what are the pending work items on each associate name. The overall pending items in current sprint will be sent to respective management and individual mails will be sent to respective associates.
- Implemented a python script that will track the occurrence of bugs and which test cases are affected by one particular bug in the given interval of time.
- Implemented a python script that will read data from text file which contains health check data of virtual machines and we will keep on tracking the pass percentage of machines in between certain dates and reasons for failures and raising tickets accordingly.
