testing Software Testing Techniques - Equivalence Partition Login validation
Example
The Rule:
The user will input credentials (email and password).
If credentials are valid, redirect to home page. Show an error message otherwise.
How to apply technique:
You can have a huge valid list of emails that could be used:
As well as a huge list of invalid emails
- xxx123
- foobar
- [email protected]
- ...
For passwords, you can have:
- a valid password for a specific and valid user
- non-valid password (one that does not exists on the system)
Equivalence Partition means that any element on a given individual set should be enough to design a test case.
So for represent a valid email we can choose [email protected]. There is no need to design test cases using [email protected] or another from the set of valid emails to ensure a good coverage.
For represent an invalid email we can choose xxx123
Same logic applies to password
