Confidential

Responsibilities:

• With the help of Weblogic Console, a memory leak was identified during performance test execution.
• Further analysis was done by analyzing the heap dump using Memory Analyzer tool (MAT).
• The object that was consuming large amount of memory and not releasing was reported back to the development team.
• Comtrac is the front end GUI that interfaces with the DDP billing Database. Vision is the Comtrac enhancements which helps Confidential Account Executives (CAE) to provide Install, Change of Service, Reschedule or Disconnect services to Customers.
• Vision is a web based application and interacts with other internal applications to complete its transactions.
• High response times were observed during performance test execution. Application response times improved once the internal application services were stubbed using Parasoft, proving that the downstream systems were the source of bottleneck.

Confidential

Responsibilities:

• Since this project mainly involved platform migration of existing application with minor code changes and defect fixes, the responsibility was to update existing test cases and execution on the new environment to make sure existing functionality was not broken.The project involved end to end regression testing of all aspects of Confidential point of sale.
• Test planning for sales and returns modules using all types of tendering mechanism (cash, credit cards, debit cards, gift cards)

Confidential

Responsibilities:

• Store Side Transaction
• Appliance Online (AOL) web services
• Vendor Side Application which consists of LG, Whirlpool and GE vendors
• Depot Direct and AOL applications are where the consumer can order appliances like Washer, Dryer and any Electronic devices directly from any store.
• Store Side Transaction is where costumer will order appliances from a store directly.
• Vendor Side Applications included Product Availability and Order Entry where consumer will order appliance from GE, LG and Whirlpool vendors directly. These test execution where performance tested directly on production servers.
• All the applications were web services and were scripted in LoadRunner. During performance test execution, the application JVMs which were on Tomcat servers (Store-Side and AOL) was monitored using in-house JVM monitoring tool, GridStats.
• Following were the performance test execution details:
• During the test execution, the AOL web service application had high response time. This was due to database and application QP servers being located in different locations whereas the production servers were at same location. The database and application servers for QP were placed at same location and the response time looked good.
• The Vendor Side application for GE had high response time and CPU utilization was 80% during test execution. The production server count was increased and re-tested. The response time was reduced from 2 minutes to few seconds and the CPU utilization was reduced from 80% to 30%.
• All the applications were stress tested. The applications were able to handle 4 to 5 times that of usual production load.
