The right way to manage your load testing project

The right way to manage your Load testing projects

Performance test main goals
Validates system under load with KPI/SLA system requirements
Verify system functionality under load
Help configure the system from performance aspects
Identify Performance system issues

Test Performance on What Level?
Unit test
Sub system test
System test
Production
The Cost of Fixing Software Defects: The later in the development cycle— the higher the cost $0 $100 $1,000 $10,000 Design Code Unit Integration System Release Maintenance

Load Testing
# of CSRs
# of transactions per peak hour
Runs this test for a long period of time without shutting down
Checks the transaction’s time in the application under load conditions
Verifies that the system comply with the load requirements (i.e. operates according to a defined response time when maximum inputs are loaded into the system)

Volume Testing Verifies that the system complies with the volume requirements (i.e. operates in a defined response time when the system data bases are populated to maximum) # of data pool Load DB with Max data Test the system with Max data

Stress Testing
Examples:
Maximum data inflation
# of maximum records
# of maximum users
Evaluates the system behavior at or beyond the limits of its specified load and volume requirements

First step Definition – analyze the system

First step Definition – Performance Test Plan
Test Plan document include
Environment architecture
Testing tools
Performance Test scope
Running scenario
Entry/Exit Criteria
Time table
Defect Tracking
Roles & responsibilities
Measure of success
Risk assessment

First step Definition – Define Load Testing tool Load Runner

First step Definition – Define Load Testing tool JMeter server types (web-http,https SOAP DB via jdbc LDAP JMS mail POP 3)

First step Definition WebLoad web load support

First step Definition Team System

First step Definition – Monitor Tools Windows Performance monitor

First step Definition – Monitor Tools Unix Performance monitor - Top

Preparation - Estimation module A tool helps to calculate the exact dates will need in order to perform the performance activities

Preparation – Work Plan After we got the number of working days required for the project will gather it on a calendar

Development & configuration
Test environment preparation and data inflation
Script Development
Scenario configuration

Execution
Execute 30% 50% 100%

Analyze results & Recommendation
There is a problem OR the problem is here???
Help the development team to find the problem
Configuration issues and recommendation

Load Testing reports –Templates

Load Testing reports – Templates cont. Comparison XLS report table

Run & Analyze the scenario Bottlenecks Statistics Example
