tiny-autounit

Yet another java auto unit testing generation tool.

It's tiny, no need to import other dependencies, jar size totally less than 30kb.

Class settings:

For a single class, you can put @UnitWalk annotation on top of it to make the class generates the unit testing class automatically.

If any methods that you don't want to generate it, then @UnitExeclude on this method can rescue.

Sample code below:

    @UnitWalk
    public class UnitBizService implements IUnitBizService {
   
       @Resource
       private IPriceCalcService priceCalcService;
   
       @Resource
       private ISubmitOrderService submitOrderService;
   
       public String proecess(PriceEntity priceEntity) {
           priceCalcService.calc("sss");
           System.out.println("process work biz");
           OrderModel orderModel = new OrderModel();
           submitOrderService.submit(orderModel);
           return "";
       }
   
       public void proecess1() {
           priceCalcService.calc("sss");
           System.out.println("process work biz");
       }
   
       public void proecess2() {
           priceCalcService.calc("sss");
           System.out.println("process work biz");
       }
   
       public void proecess3() {
           priceCalcService.calc("sss");
           System.out.println("process work biz");
       }
   
       @UnitExeclude
       public void proecess4() {
           priceCalcService.calc("sss");
           System.out.println("process work biz");
       }
   
       public void proecess5() {
           priceCalcService.calc("sss");
           System.out.println("process work biz");
       }
   }

Sample above is easy to use for small project really, But when our project is large and adding @UnitWalk on top of the classes will bring us nightmare. Consider this, this structure provides @UnitScan annotation to specific the scan package. When the project bootstraps, then the structure will scan the package in @UnitScan annotation to work.

After the settings, we can bootstrap the structure by following code:

        UnitBootStrap unitBootStrap = new UnitBootStrap();
        unitBootStrap.start("org.tiny.autounit.test.biz");

Need to mention that , the package name in above code is the package that will fill into the generated unit test class.

Putting above bootstrap code into main entrace and start the project, then we can get the automated generated unit class below:

}

This structure is still under design, any advice or push will be appreciated.
