Pure java testing framework implementation

Motivation

Spock framework is fantastic but use groovy to test java always will be become a mess. After executing a test that should fail and does not fail. Decided that this must be done in pure java.

Quick start

(Please read our Javadoc for further information)

First of all include the Jar file in your compile and execution classpath.

Maven

<dependency>
    <groupId>org.bytemechanics</groupId>
    <artifactId>test-drive</artifactId>
    <version>X.X.X</version>
    <type>test</type>
</dependency>

In your maven pom.xml activate the surefire test-drive provider by adding the corresponding dependency

 <build>
     <plugins>
         <plugin>
             <groupId>org.apache.maven.plugins</groupId>
             <artifactId>maven-surefire-plugin</artifactId>
             <version>X.XX.X</version>
             (...)
             <dependencies>
                 <dependency>
                     <groupId>org.bytemechanics</groupId>
                     <artifactId>testdrive-surefire</artifactId>
                     <version>X.X.X</version>
                 </dependency>
             </dependencies>
         </plugin>
     </plugins>
 </build>

In your maven pom.xml activate the suffix you will use (tipically Spec)

 <build>
     <plugins>
         <plugin>
             <groupId>org.apache.maven.plugins</groupId>
             <artifactId>maven-surefire-plugin</artifactId>
             <version>X.XX.X</version>
             <configuration>
                 <includes>
                     <include>*Spec.java</include>
                     (...)
                 </includes>
             </configuration>
             (...)
         </plugin>
     </plugins>
 </build>

Create your first spec

Option 1: non-driven

import org.bytemechanics.testdrive.Specification;
import org.bytemechanics.testdrive.annotations.Evaluation;
import org.bytemechanics.testdrive.annotations.Test;
import org.bytemechanics.testdrive.Assert;

public class AddIntegerSpec implements Specification {

   (...)

	@Test(name="accumulate {} and {} should result with {} with driven test", evaluations = {
		@Evaluation(name = "one",args = {"1","1","0","2"}),
		@Evaluation(name = "zero",args = {"0","0","0","0"})
	})
	public void accumulate(final int _base,final int _val1,final int _val2,final int _expected){

       int base=_base;
       int actual=base+_val1+_val2;
       Assert.assertEquals(actual,_expected);
	}
   (...)
}

Option 2: non-driven with labels

import org.bytemechanics.testdrive.Specification;
import org.bytemechanics.testdrive.annotations.Evaluation;
import org.bytemechanics.testdrive.annotations.Test;
import org.bytemechanics.testdrive.Assert;

public class AddIntegerSpec implements Specification {

   (...)

	@Test(name="accumulate {} and {} should result with {} with driven test", evaluations = {
		@Evaluation(name = "one",args = {"1","1","0","2"}),
		@Evaluation(name = "zero",args = {"0","0","0","0"})
	})
	public void accumulate(final int _base,final int _val1,final int _val2,final int _expected){

       int base,actual;

       given:
           base=_base;
       when:
           actual=base+_val1+_val2;
       then:
           Assert.assertEquals(actual,_expected);
	}
   (...)
}

Option 3: driven

import org.bytemechanics.testdrive.DrivenTest;
import org.bytemechanics.testdrive.Specification;
import org.bytemechanics.testdrive.annotations.Evaluation;
import org.bytemechanics.testdrive.annotations.Test;
import org.bytemechanics.testdrive.example.AddInteger;
import org.bytemechanics.testdrive.exceptions.AssertException;
import org.bytemechanics.testdrive.Assert;

public class AddIntegerSpec implements Specification {

   (...)

	@Test(name="accumulate {} and {} should result with {} with driven test", evaluations = {
		@Evaluation(name = "one",args = {"1","1","0","2"}),
		@Evaluation(name = "zero",args = {"0","0","0","0"})
	})
   public DrivenTest accumulateDriven(final int _base,final int _val1,final int _val2,final int _expected){
       return new DrivenTest() {

           int base,actual;

           @Override
           public void given() {
               this.base=_base;
           }
           @Override
           public void when() {
               this.actual=this.base+_val1+_val2;
           }
           @Override
           public void then() throws AssertException {
               Assert.assertEquals(this.actual,_expected);
           }
       };
   }
   (...)
}
