Traditional Testing vs. Unit Testing

Traditional testing

---

Traditional testing tests the system as a whole.

---

In traditional testing:

• Individual components are rarely tested
• Errors go undetected
• Isolation of errors is difficult to track down

Traditional testing strategies

The various strategies of traditional testing are:

• Print statements
• Use of a debugger
• Debugger expressions
• Test scripts

Drawbacks of traditional testing strategies

Instead of testing the system as a whole, it is always better to test individual components so that we have confidence in the overall system.

Traditional testing strategies are not adequate to test individual components. In this case, unit testing is a better strategy.
