| TimeContext | | abstract public class TimeContext extends TestContext (Code) | | This class represents a
TestContext test context specialized
for measuring execution time.
TimeContext implementations may perform assertions based upon the
execution time. For example:[code]
class MyTestCase extends TestCase() {
...
public void validate() {
long ns = TimeContext.getAverageTime("ns");
TimeContext.assertTrue(ns < 100); // Error if execution time is more than 100 ns.
...
}
}[/code]

| Field Summary | |
| final public static Configurable | DEFAULT
Holds the time context default implementation (by default logs
average and minimum execution time to System.out). | | final public static Class | REGRESSION
Holds an implementation which does not perform any logging but raises an
AssertionException when an assertion fails, including any timing
assertion. | | final public static Configurable | TEST_DURATION_MS
Holds the minimum duration of each test case execution (default 2000 ms). |
| DEFAULT | | final public static Configurable DEFAULT(Code) | | Holds the time context default implementation (by default logs
average and minimum execution time to System.out).
|
| REGRESSION | | final public static Class REGRESSION(Code) | | Holds an implementation which does not perform any logging but raises an
AssertionException when an assertion fails, including any timing
assertion.
|
| TEST_DURATION_MS | | final public static Configurable TEST_DURATION_MS(Code) | | Holds the minimum duration of each test case execution (default 2000 ms).
The larger the number the more accurate is the average time result; but
the longer it takes to run the test.
|
| exit | | public static Context exit()(Code) | | Exits the current time context.
the time context being exited.
throws:
ClassCastException - if the context is not a stack context. |
| getAverageTime | | public static long getAverageTime(String unit)(Code) | | Returns the average execution time of the latest execution performed or
-1 if the current context is not a time context.
Parameters:
unit - one of "s", "ms", "us", "ns", "ps" the average execution time stated in the specified unit. |
| getAverageTimeInPicoSeconds | | public long getAverageTimeInPicoSeconds()(Code) | | Returns the average execution time of the latest execution stated in
pico-seconds.
the time in pico-seconds. |
| getMaximumTime | | public static long getMaximumTime(String unit)(Code) | | Returns the maximum execution time of the latest execution performed or
-1 if the current context is not a time context.
Parameters:
unit - one of "s", "ms", "us", "ns", "ps" the maximum execution time stated in the specified unit. |
| getMaximumTimeInPicoSeconds | | public long getMaximumTimeInPicoSeconds()(Code) | | Returns the maximmum execution time of the latest execution stated in
pico-seconds.
the time in pico-seconds. |
| getMinimumTime | | public static long getMinimumTime(String unit)(Code) | | Returns the minimum execution time of the latest execution performed or
-1 if the current context is not a time context.
Parameters:
unit - one of "s", "ms", "us", "ns", "ps" the minimum execution time stated in the specified unit. |
| getMinimumTimeInPicoSeconds | | public long getMinimumTimeInPicoSeconds()(Code) | | Returns the minimum execution time of the latest execution stated in
pico-seconds.
the time in pico-seconds. |
