What is Error Guessing Testing Technique?
Error Guessing technique is a Software Testing technique on guessing the error which can prevail in the code.
The main purpose of this technique is to guess possible bugs in the areas where formal testing would not work.

-
-
- Experience of the tester is utilised to guess the problematic areas of the application.
- This technique necessarily requires skilled and experienced testers.
- It is a type of Black-Box Testing technique and can be viewed as an unstructured approach to Software Testing.
- This technique can be used at any level of testing.
- It is the process of making an educated guess as to other types of areas to be tested.
- main purpose is to concentrate the testing action on regions that have not been taken care of by the other more formal methods.
-
Some common areas of error guessing:
-
-
- Divide by zero
- Null pointer exception
- Entering blank spaces in the text fields
- Pressing the submit button without entering values.
- Uploading files exceeding maximum limits.
- Invalid parameters
- Refresh buttons
-
Benefits/Advantages of Error Guessing technique:
-
-
- Effective when used in combination with other formal testing techniques.
- Reveals those defects which would otherwise not be possible to find out, through formal testing.
- Saves a lot of time and effort.
- Helps in errorguessing of complex and problematic areas of the application.
-
Drawbacks of ErrorGuessing technique:
-
-
- Dependent on testers experience and skills
- Does not guarantee that the software has reached the expected quality.
- Does not provide full coverage of the application
