Running tests from eclipse failed

[Umesh]

I'm trying to run a simple JUnit test with PowerMockRunner.

I get the following error when I run each of the test methods
individually.

ShoppingCartManagerTest.addToCartWithNoInventory
Unrooted Tests
initializationError0(org.junit.runner.manipulation.Filter)
java.lang.Exception: No tests found matching Method

This error occurs only when i try to run a test method individually
and doesn't occur when the test class is run.

I have a @PrepareForTest for each of my test method.

Please let me know if any of you faced this problem earlier and had a
solution to it.

Try using @PrepareForTest at the class-level of your test and see if that helps. You should only use it on method-level in very special cases.

It works fine when @PrepareForTest at the class-level. However, my
requirement is to use it at the method level.

Any inputs on this would be extremely helpful.

Why do you need it at the method level?

I have a set of test cases each having few test methods. Only few of those test methods need @PrepareForTest to be configured.
Below is a code snippet of what I'm trying achieve with Powermock.

@RunWith(PowerMockRunner.class)
public class ShoppingCartManagerTest {

    @Test
    @PrepareForTest(Utils.class)
    public void addToCartWithNoInventory() {
        // this method mocks call to inventory database
       
        // inventory service uses Utils class to perform some validation
    }
   
    @Test
    public void addToCartWithActualInventory() {
        // this method retrieves actual inventory from the database
       
        // Utils class should not be mocked here
    }
}

Can you please suggest if there is any alternative method to achieve this?

Usually it is good practice to separate unit testing and integration
tests. I recommend that you separate your test into two different
classes, one unit test where you use PrepareForTest and one
integration test class. You could still reuse common validation
methods if you need to.

Often I also use a separate transaction for each integration test, for
example using Spring Framework. This is often also configured at the
class level.

Agree and it makes sense to me. I'll try that option. Thanks for the help.
