Can we exclude few tests from @BeforeClass?

[Jagriti Jain]

Hi,

I have a

   @BeforeClass

   public void setup(){

   

    //create restaurant id (say)

   }

  @Test(description="test 1")

   void restaurantIdDeleted(){

   .....

   } 

   @Test(description="test 2")

    void restaurantNameChanged(){

    ------

    }

  

   @Test(description="test 3")

    void menuItemChanged(){

   ------

   }

.......

The Before Class runs once and then the individual tests run 1 by 1.

Now, I have test1 which actually deletes the restuarantId which was generated in @BeforeClass, and test2 and test3 will fail now.

So, I thought of using @BeforeMethod instead of @BeforeClass, but then if I have 20 methods, then I am literally creating 20 restaurantIds, which is undesirable. I want a way to exclude 2-3 methods in which I am performing deletion or deactivation of restaurantId using @BeforeClass.

Please let me know if this is possible.

Jagriti,

 

You can do this very easily by following the below steps:

 

1. Define a marker interface which indicates that setup has to be skipped for a particular test.
2. Annotate all test methods for which setup is to be skipped, using the interface defined in (1).
3. Within your @BeforeMethod inspect the incoming “ITestResult” object and retrieve the method’s annotation to check if the marker interface defined in (1) was used to annotate the method. If the annotation was present, skip running the beforeMethod, else execute it.

 

The below sample shows this in action.

 

import static java.lang.annotation.ElementType.METHOD;

import java.lang.annotation.Retention;
import java.lang.annotation.Target;
import org.testng.ITestNGMethod;
import org.testng.ITestResult;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.Test;

public class SelectiveConfigurationExecutionSample {

  @BeforeMethod
  public void beforeMethod(ITestResult result) {
    ITestNGMethod method = result.getMethod();
    SkipSetup skipSetup =
        method.getConstructorOrMethod().getMethod().getAnnotation(SkipSetup.class);
    if (skipSetup == null) {
      System.err.println("Running  setup for the method " + method.getMethodName() + "()");
    } else {
      System.err.println("Skipping setup for the method " + method.getMethodName() + "()");
    }
  }

  @Test
  public void a() {}

  @Test
  public void b() {}

  @Test
  @SkipSetup
  public void c() {}

  @Test
  public void d() {}

  @Test
  public void e() {}

  @Test
  @SkipSetup
  public void f() {}

  @Test
  public void g() {}

  @Retention(java.lang.annotation.RetentionPolicy.RUNTIME)
  @Target({METHOD})
  @interface SkipSetup {}
}

 

 

Running  setup for the method a()

 

Running  setup for the method b()

Skipping setup for the method c()

 

Running  setup for the method d()

Running  setup for the method e()

 

Skipping setup for the method f()

Running  setup for the method g()

 

===============================================

Default Suite

Total tests run: 7, Passes: 7, Failures: 0, Skips: 0

===============================================

 

 

Process finished with exit code 0

 

 

 

 

 

 

 

 

Thanks & Regards

Thanks for answering Krishnan, however I didn't get:

 SkipSetup skipSetup =
        method.getConstructorOrMethod().getMethod().getAnnotation(SkipSetup.class);

you created a separate class elsewhere called Skipsetup, and then you created an object of this class called skipsetup, what exactly was there in the Skipsetup class, this might be silly, but I am a newbie.

Also there are Target and Retention annotation being used, I have never used them earlier.

[Jagriti Jain]

attaching screenshot from my code, can't find Skipsetup

[Krishnan Mahadevan]

Did you create a new class with the custom annotation SkipSetup ?

 

In the sample that I shared, I included its definition as a nested class. But you can have it reside in a separate file as well.

 

SkipSetup is a marker annotation.
