| 27 | <h2>Delayed Constraint (NUnit 2.5)</h2>
|
|---|
| 28 |
|
|---|
| 29 | <p><b>DelayedConstraint</b> delays the application of another constraint until a certain
|
|---|
| 30 | amount of time has passed. In it's simplest form, it replaces use of a Sleep
|
|---|
| 31 | in the code but it also supports polling, which may allow use of a longer
|
|---|
| 32 | maximum time while still keeping the tests as fast as possible.
|
|---|
| 33 |
|
|---|
| 34 | <p>The <b>After</b> modifier is permitted on any constraint, and the delay applies to
|
|---|
| 35 | the entire expression up to the point where <b>After</b> appears.
|
|---|
| 36 |
|
|---|
| 37 | <p>Use of a <b>DelayedConstraint</b> with a value argument makes no sense, since
|
|---|
| 38 | the value will be extracted at the point of call. It's intended use is with
|
|---|
| 39 | delegates and references. If a delegate is used with polling, it may be called
|
|---|
| 40 | multiple times so only methods without side effects should be used in this way.
