how to write JUnit test cases for spring application using annotations

The Spring documentation on testing is pretty good, although (to me at least) seems to not be covered in the best order. Therefore, I suggest to check out the docs here...

http://docs.spring.io/spring/docs/3.1.x/spring-framework-reference/html/testing.html

...but probably start reading from section "10.3.5 Spring TestContext Framework".


In a nutshell though, the annotations that will be of the biggest use to you are...

@RunWith(SpringJUnit4ClassRunner.class)
// This is a JUnit annotation enables Spring functionality



@ContextConfiguration({"/app-config.xml", "/test-config.xml"})
// If you use XML based Spring configuration

       or

@ContextConfiguration(classes={AppConfig.class, TestConfig.class})
// If you use JavaCofig based Spring configuration

Select allOpen in new window

Once you have this setup, you can use normal Spring @Autowired annotations to inject references from your Spring configuration into your test class, and then use the normal JUnit annotations to run your tests.


If you can provide more information about your unique situation/requirements we can probably help a little more too.

I've requested that this question be deleted for the following reason:

i know those steps

You need to provide a proper explanation for deleting the question. What you have done is not sufficient. If you don't do that then the delete request will be stopped and you will need to close the question in a different way.

I'm objecting to the deletion of this question, as I believe my comment (http:Q_28299158.html#a39664483) sufficiently answers the (very briefly worded) question. Also, the question author has made no attempt to follow up on my comment or ask additional questions. And finally, the (also very briefly worded) explanation for deletion is inadequate. Attempts to resolve this with the question author have been ignored.

sorry for that attempt actually i postponed  my practice. i need to test spring application using junit testcasese.

i created one testcase and i imported those two steps
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:data-servlet.xml"})
after  that i called one method i inserted hard code values finally i called service mehod

while running the junit test  i am getting error.

Failed to load ApplicationContext

parsing XML document from class path resource [data-servlet.xml]; nested exception is java.io.FileNotFoundException: class path resource [data-servlet.xml] cannot be opened because it does not exist

class path resource [data-servlet.xml] cannot be opened because it does not exist

any problem if i import the statement like this @ContextConfiguration(locations = {"classpath:data-servlet.xml"})
can u give a proper suggestion for me.

any problem if i import the statement like this

No, it appears that you are correctly using the ContextConfiguration annotation. The problem might be exactly where Spring is looking for the file.

Can you tell me the exact directory that your "data-servlet.xml" is located in? Also can you tell me the package name that this TestCase class has?

directory location for data-servlet.xml is:
WebContent/WEB-INF/data-servlet.xml

pkg name for Test class:
com.hcltech.poc.ets.test.ManagerPageControllerTest

pkg name for Service class:
com.hcltech.poc.ets.service.TaskServiceProvider

Thanks for your suggestions i have a habit like if i didn't get the solution for my question i will delete my question from the portal i think mccrl you saw only my answered questions previously i deleted many questions because of i didn't get exact input from experts.

I dont know A is the default rating just now i saw the ratings.

i got the proper input from you.Thanks for your suggestion.

@srikotesh,

Thanks for accepting, and explaining why your reasons for grading the way your did.

And to follow from what SouthMod posted, I didn't bring this up just for my own benefit, or to enforce the policy for sake of enforcing it, but to help you to hopefully get a high level of help from the other experts here. :)

Cheers
mccarl
