Why Testing?

Why do we need to Test Software?

• Make sure the software fulfills the Requirements from the Customers (Software Requirements Specification, SRS)
• Make sure the Software don't contain critical Bugs
• Make sure the software can be installed at the customer. The customer don't have Visual Studio!
• Make sure the software are user-friendly an intuitive to use
• Make sure the software is robust and has acceptable performance (so it don't crash when more than 1 person are using it, the database contain lots of data, etc.)

Unit Testing

What are Unit Tests? Unit Testing (or component testing) refers to tests that verify the functionality of a specific section of code, usually at the function level. In an object-oriented environment, this is usually at the class and methods level. Unit Tests are typically written by the Developers as part of the programming. The Unit Tests are typically automatically executed (e.g., by Visual Studio and Team Foundation Server/Visual Studio Team Services, which have have built-in functionality for Unit Testing).

Test Environment

Why do we need a Test Environment?

• “It works on my computer” says the Developer
• A Clean Environment is needed
• On the Developers PCs we have all kind of Software installed that the Customer don't have, e.g. Development Tools like Visual Studio, etc.
• We need to test on different Platforms and Operating Systems
• Customers may use different Web Browsers
• Deployment: Test of Installation packages
• Make the software available for Testers etc.
