1] Software Testing.
2] STLC
3] Performance Testing.
The intent of finding
an error.
To identify actual and
expected results.
process of determining the speed or effectiveness
PT has three dimensions
- Number of Users
- Amount of Data
- Amount of Activity
Performance is Dependant
Resources
Bottlenecks & Wait times
Factors
Throughput
Response Time
Tuning
Benchmarking
Client side – Time, Pass Fail Statistics,
Throughput, Hits/sec, Customized Functionality Validation Counters, User Abandonment
Server-side – Performance related
metrics and observations for Web Server (s), Application Server (s) and/or Database Server (s)
Load Testing
- Process of exercising the system under test.
-Constantly increasing the load on the system via automated tools.
Examples:
1. Testing a word processor by editing a very large document.
2. For Web Application load is defined in terms ofconcurrent
Stress Testing –
-Trying to break the system under test
-To make sure that the system fails and recovers gracefully.
Example:
1. Double the baseline number for concurrent users/HTTP connections.
2. Randomly shut down and restart ports on the network
1. To identifies problems.
2. Reduces development cycles.
3. Produces better quality.
4. system meets performance
expectations such as –
response time, throughput
etc. under given levels of load.
Expose bugs, such as memory management bugs, memory leaks, buffer overflows, etc.
