| 27 | <h2>String Constraints (NUnit 2.4)</h2>
|
|---|
| 28 |
|
|---|
| 29 | <p>String constraints perform tests that are specific to strings.
|
|---|
| 30 | Attempting to test a non-string value with a string constraint
|
|---|
| 31 | is an error and gives an exception.
|
|---|
| 32 |
|
|---|
| 33 | <p>The <b>Text</b> prefix is deprecated beginning with NUnit 2.5.1
|
|---|
| 34 | and will be removed in NUnit 3.0.
