Tracer makes it easy to log the execution time of any test written in Java.
Using the @TracedTest annotation we can log and even benchmark multiple runs of the same test.
| Type | Name | Default value | Description |
|---|---|---|---|
| int | iterations | 1 | How many times the test should run. |
| TimeUnit | timeunit | TimeUnit.MILLISECONDS | What time unit the duration values should be outputted as. |
All we need to do in order to use Tracer is extending our test class with the TestWithTracer class,
and annotate the method we want to trace with @TracedTest.
public class MyTestClass extends TestWithTracer {
@Test
@TracedTest(iterations = 100, timeunit = TimeUnit.MICROSECONDS)
public void shouldTestSomething() {
// Your awesome test here
}
}Output:
16:29:58.153 INFO com.tyrill.tracer.TestWithTracer : shouldTestSomething execution took: 24564 MICROSECONDS
16:29:58.182 INFO com.tyrill.tracer.TestWithTracer : 100 isolated invocations took: 203058 MICROSECONDS
16:29:58.184 INFO com.tyrill.tracer.TestWithTracer : Average: 2045.55 MICROSECONDS
- Add option for failure "threshold": so that the test will fail if execution time takes longer than this threshold.
- Maven-central / gradle availability.
- Support Trace of non-test methods using simple AOP.
