General usage instructions

Generates Test Cases is a port of Eclipse's generate test cases plugin described here:

You can see a 10 minutes video to grasp the concept in a really easy way here:

This project aims to make it easier to make TDD with a really cool and easy approach that consist in annotating interface method with desired behaviours like this:

public interface Person {

* @return
* @should say hello, and nothing more that that
String sayHello();


So with this plugin you could generate a test class for this interface like this one automatically:

public class PersonTest extends TestCase {
* @verifies say hello, and nothing more that that
* @see Person#sayHello()
public void testSayHello_shouldSayHelloAndNothingMoreThatThat() throws Exception {
//TODO auto-generated"Not yet implemented");

And then test your implementation code like this

public void sayHello_shouldSayHelloAndNothingMoreThatThat() throws Exception {
assertThat(instance.sayHello(), is("hello world"));

This way you can realize that for testing this behaviour you just wrote the should annotation in the sut (system under test) in a really descriptive way.

@should say hello, and nothing more that that

Auto-generated the test class and test method (using the plugin) and then tested the actual expected behaviour with (hamcrest style junit test):

assertThat(intance.sayHello(), is("hello world"));

Usage Instructions:

Open class in editor and press the "Generate Test Methods" button in toolbar to generate test methods for @should style annotations added to methods in javadoc
