Internet Application Testing

• By Akash Agarwal

2
The NEED to Test

• Is the site content meaningful?
• Is this application easy to use?
• How about browser compatible?
• Are we using the right tools?
• How reliable is our technology?
• Do the Servers have enough power?
• How many visitors are we expecting?
• Are the machines fast enough?
• How much activity can the site handle?

Testing a Web Site

• There are mainly two essential types of testing
  that should be accomplished.
• Functionality
• Performance

4
Functionality Testing

• What is it?
• Why is so important?
• Different kinds
• Unit Test
• Integrated Test
• Functional Test
• System Test
• Regression Test

5
Functionality Testing

• Set of procedures verifying application works as
  expected.
• Why important?
• Page display errors
• Runtime errors
• Improper links
• Missing pictures
• Many other errors

Functionality Testing

• Unit Testing - basic component level testing.
• Functional testing - identifying valid, invalid
  inputs and outputs.
• Integration testing - testing combine parts of an
  application.
• System testing - behaviors exposed by testing the
  entire integrated system.
• Regression testing tests to ensure that no
  adverse changes occur during maintenance or
  upgrades.

Performance Testing

• What is it?
• Why is so important?
• Different kinds
• Load Test
• Stress Test

11
Performance Testing

• Determine runtime behavior of application.
• Used to measure several characteristics.
• Why important?
• To determine performance extracted from the
  system.
• To determine maximum load and stress can handle.
• To prevent bottlenecks.

12
Performance Testing

• Load Testing determine application behavior
  under load.
• Stress Testing determines applications ability
  to handle large amounts of data.

13
Conclusions

• Test every internet application developed.
• Perform FUNCTIONALITY testing.
• Test under LOAD and STRESS
• Test early and Test often.
• Effort used in testing is an investment.
