Configure core annotations with a global scope

@MeasureExecutionTime

Measure execution time of test method.

🔎 Example

[QUICK PERF] Execution time of test method: 5 s 289 ms (5 289 245 600 ns)

⚠️ Be cautious with time measurement results. It is a rough and first level result. Data has no meaning below the seconde / millisecond. JIT warm up, GC or safe points can impact the measure and its reproducibility. We recommend JMH to do more in depth experiments.

@ExpectMaxExecutionTime

The test will fail if the execution time is greater than expected.

It can be useful to configure this annotation with a global scope.

🔧 Elements

Name	Type	Meaning	Default value
hours	int	Number of hours	0
minutes	int	Number of minutes	0
seconds	int	Number of seconds	0
milliSeconds	int	Number of milli seconds	0

You can use several elements together, as shown in the following example.

🔎 Example

@ExpectMaxExecutionTime(seconds = 2)

[PERF] Execution time of test method expected to be less than <2 s> but is <5 s 286 ms (5 285 734 000

@DisplayAppliedAnnotations

Display applied QuickPerf annotations in console.

An annotation can have three scopes (gobal, test class, test method). This annotation is useful to see which annotations are applied on a test method.

🔎 Example

[QUICK PERF] Applied annotations: @JdbcBatches(batchSize=30), @DisableSameSelectTypesWithDifferentParamValues
             Class specifying global annotations: org.quickperf.QuickPerfConfiguration

@DisableGlobalAnnotations

Disable global annotations on test method or test class.

🔧 Elements

Name	Type	Meaning	Default value
comment	String	Comment why global annotations are disabled	-

@DisableQuickPerf

Disable QuickPerf features.

@FunctionalIteration

Disable QuickPerf features.

@DebugQuickPerf

This annotation is addressed to developers working on QuickPerf annotations.
It displays information in console for debugging purpose.

Configure core annotations with a global scope

Annotations having a global scope apply on each test.

org.quickperf.annotation.CoreAnnotationBuilder helps to configure core annotations with a global scope.

🔎 Example

package org.quickperf;

import org.quickperf.annotation.CoreAnnotationBuilder;
import org.quickperf.config.SpecifiableGlobalAnnotations;

import java.lang.annotation.Annotation;
import java.util.Arrays;
import java.util.Collection;

public class QuickPerfConfiguration implements SpecifiableGlobalAnnotations {

    public Collection<Annotation> specifyAnnotationsAppliedOnEachTest() {

        return Arrays.asList(
          
                CoreAnnotationBuilder.expectMaxExecutionTimeOfMilliSeconds(500)

        );

    }

}

⚠️ The class implementing SpecifiableGlobalAnnotations has to be in org.quickperf package.
