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.
