I have generated test class using jtest IDE.
I want to run this code in my normal eclipse editor
How to do that?
How to use this sonarqube?
@subratdash8 : Which JTest version are you using? This is a very important piece of information we need to determine your next steps. Second question is what is the purpose of using SonarQube here? Display of test results and coverage in a dashboard? Correct?
Hi @Andrey Madan
I think it's 9.3.
In our project currently we r using sonarqube to display code coverage and tesr case success rate to client.Recently we have started using JTest.
So can we do that?
Thanks in advance
@subratdash8 : JTest 9.3 is a pretty old version. If you generate tests using this version, you will have to use older maven/ant plugins to integrate with CI/CD process. How far have you advanced in using the JTest 9.3? JTest 9.x product line is not designed to submit data to SonarQube.
The good news, the new JTest line of products which is giving you ability to not only create pure JUnits but also easily integrate with your CI/CD pipeline and publish results to a more advanced reporting and analytics ecosystem (DTP). Check out this awesome blog post from @Mark Lambert : https://blog.parasoft.com/why-people-hate-unit-testing-and-how-to-bring-back-the-love . If you have further questions after reading and listening to the blog video, please contact your friendly Parasoft representative.
Jtest 9 builds test cases that require Jtest libraries in order to run. It does not build test cases that use Mockito. Instead if you switch to Jtest 10, then you will be able to build maintainable test cases that run on their own without any Parasoft dependencies. The test cases built by Jtest 10 use Mockito for mocking.
After reviewing our documentation, I can see how it can be confusing. I will recommend that we update the documentation to be clearer.
When creating tests using the Regular or Parameterized actions, UTA does not automatically create mocks or instantiate objects (other than the object under test). When creating tests using the "Add test case(s)" action, mocks will be automatically generated. This is intentional - the Regular and Parameterized actions allow you to build the unit test a piece at a time, whereas the "Add test case(s)" option is for building more fully-configured tests.
@Andrey Madan thanks..
But I have one doubt. After generating test classes in jtest IDE can I use same code in junit class in normal eclipse IDE.
Currently we are using mockito framework to mock data service or any dependency call.In jtest I can see the stup is getting created for that call.
But how to integrate this functionality in junit after creating stub code in jtest editor.
Thanks in advance.
Can we use jtest library in junit test class??
Thanks in advance.
@subratdash8 : It's just a library, so yes. However, I would strongly recommend upgrading to JTest 10 and Unit Test Assistant. The test cases created by UTA will be much easier integrated with your workflow (CI / Mockito, etc). You WILL save yourself a lot of headaches down the road.
Do you mean to ask if you can use the Jtest 9 library in a JUnit test class when running in an IDE that does not have Jtest installed? I would suspect it is possible but I have not done it so I don't know how easy or if it is actually possible.
Do you have existing test cases built with Jtest 9? Or are you just starting out in building test cases? Because if you are just starting out, you really want to use Jtest 10 - the test cases are MUCH cleaner and can be run independently of Parasoft.
Using Jtest 9.x library for test case execution.
Generally, I could say that You need Jtest tool to correctly execute these test cases. These test cases are using few features like parameterization, stubs and other utilities to realize some functionality and should be executed by Jtest tool.
Also Jtest tool is use to provide information about coverage.
When you are saying jtest 9 or 10,what does it mean?
It means only library like jar or it's version of editor that is used for jtest.
Currently I am using parasoft jtest editor for that.
I am confused what is actually jtest means.
Currently we are using maven and sonarqube for build and report generation to show code coverage.
I don't have idea how to use this with jtest.
I am new to this thing.
Any pointers would be helpful for me.
By saying Jtest 9 vs 10 we say about tool - whole plugin to IDE.
Jtest 9 was delivered only as plugin to Eclipse.
Jtest 10 is devliery as pluign to Eclipse, IntelliJ or Netbeans.
jtest.jar - is only small library which realize extra features in test cases generated by Jtest.
Finally I got jtest 10 version.. I am exploring its feature. One issue that I have noticed is
For EJB object it is not creating stub method by itself. So it's initial with null
So is it not possible for jtest to mock ejb object and if it is possible how to do that?
Waiting for you response..
Depending on which action you used to create the test with Unit Test Assistant, objects like EJBs may not be instantiated by default. This gives you the opportunity, when building tests, to decide whether you want a real object or a mock in the test.
If you select the local variable in the code editor, you can either instantiate it (using a constructor or factory method) or mock the object (using Mockito) using an action in the Unit Test Assistant view.
Thanks for your response. But as per jtest documentation if there is any other module call exist to do isolate test jtest will automatic mock dependent class objects.
So why we can't do in case of EJB?
Correct me if I am wrong.
Thanks for your response.
When I am trying to create junit for 1 method I can see only 1 test methods getting formed. Buy we have different scenarios. So as per my understanding jtest should create junit based on different scenarios not only 1 method to cover only 1 scenario.
Correct me if I am wrong *
In Jtest 9.x, generating tests did build multiple test methods for each method-under-test; with Jtest 10.x, we have moved away from this paradigm because it often resulted in incorrect and un-maintainable tests. Unit Test Assistant is designed to provide a guided test-creation workflow, where developers define the scenarios they need for each method. We have found that in nearly all cases, a using the guided test creation paradigm results in better, more maintainable tests than the all-automatic approach.
I would also recommend reaching out directly to our support team or a Parasoft representative - we would be happy to take a closer look at what you are trying to accomplish and help you get there.
Thanks for your response.. I am arranging a meeting with jtest team. Before that I am just clarifying some open point so that I can explain to my team.
So can we mock this type of object like ejb or if we are calling methods of different class then mocking of that function call part, by jtest instead manually after creating test methods.?
I mean can we ask jtest to mock one class or one function call after its created jtest method?
The answer to this question will solve our many doubts.
Thanks in advance
Hi @subratdash8 ,
Yes, you can mock an EJB and its methods. If you select a local variable that is initialized to null, you can use the Mock it action to instantiate the EJB as a mock. Alternatively, you can use Deep Setup to automatically mock the EJB and any method calls being made to it from the method under test.
When tests are run, UTA will make recommendations for each method call on the mocked EJB, if the method is not yet mocked. There is a quick-fix link in the recommendation to automatically mock the method.
Be sure to read the documentation on mocking here: https://docs.parasoft.com/display/JTEST1033/Creating+Mocks
I have read that documentation. But I can't see that mock option in recommendation tab. And there is only option for mockito. Power mockito option i cant see in preference. I can only see mock it option for getter and setter methods.
And EJB object is initialized with null which is resulting in null pointer exception.
Is any configuration missing from ur side?
As suggested by @bmcglau, I would recommend you contact our support team as it looks like we are having a hard time understanding your use case on the forums. With that being said, here are some quick thoughts:
We have installed 10.3.4 jtest. Now we are able use power mockito feature and we can mock static method. But there is still some issue.
1.we are not able to still mock EJB object in this version. and if we are manually mocking EJB object still we can not see any recommendation to mock the function call made by that object.
2.If we are using list of some data and we are passing to source method then after creating test method by jtest , we can see that Jtest is only creating a empty list without any content. So is it a expected behaviour and we need to add content or something is missing from our side
3.If code contains some if else condition based on some scenario then Jtest is not covering all scenario.In this case do we need to manual modify value to cover all condition?
Please let me know in case you need more details
Thanks in advance
Hi @subratdash8 ,
Regarding the EJB mocking issues, I would recommend contacting and working with our support team to look into the issue further. Perhaps there is something in your EJB or related code which we need to understand in order to provide a better answer.
By default, Unit Test Assistant instantiates collections as empty lists and maps as empty HashMaps. This is expected behavior.
Jtest does not currently analyze code branches to drive test creation. As the test developer, you would configure the test to take the code branches that you want it to take, in order to test a specific code-path.
Hi @bmcglau and all
Thnaks for your response. I have raised thia concerns to my tool team and they will contact jtest team soon.
So now coming to list or map initialization and branch coverage..
1.In jtest 10.3.2..we saw its creating mock of list or map.. And 10.3.4, it is creating a empty list and map.. So can we expect this feature in higher version.. Where jtest will analyze the list and it will add mock objects into that. This feature is basically required when list contains a user defined class with lot of properties and our functions invocation depend on this data.. So if jtest can analyze this and create mock 9f objects with some mock data and add it to list then it will reduce some more efforts given by developers.
2.And same as for conditional scenarios also.. If higher version includes this..
Waiting for your input and suggestions..
Hi @subratdash8 ,
Yes, we intentionally changed our default instantiation of Collections and Maps (including Lists) to use concrete classes like ArrayList and HashMap instead of mocking them. This is because, in nearly all circumstances, the List or Map is not the object which needs to be mocked. However, when we generate tests we don't necessarily know what data you - the developer - want in the collection. In some tests, you probably want an empty collection, and in others you may want nulls or real objects, depending on the scenario you want to test. Instead of generating too much code (which quickly becomes unmanageable), we opted to initialize empty collections, and expect the developer to populate the collection. I should mention that you can easily create a local variable for an item in the list, and use UTA actions to instantiate or mock the item.
We do eventually want to make improvements to UTA in which we are able to analyze code branches to generate more complete "deep setup" tests.
Thanks for you feedback.
But one point i want to mention here.
While creating test methods jtest is mocking al input l parameters. While writing test methods may be developer need empty or null or with some data added into the list.
But anyhow we need to test scenarios where input list to function have at least one data or object for further operation which is more important in testing.
So if jtest can create mock objects with mocking parameters and add into the list then later developer will write for null or empty.
So if you can include at least one mock object in list then developer wll try for other scenarios in higher version of jtest then it will add new flavor.
And for 2nd point waiting for new version of jtest f for condition coverage.
Hi @subratdash8, thank you so much for your feedback. The suggestions that you are making directly relate to internal discussions we are having about how to make the created tests get better coverage. I have captured your feedback and we will use it as input to our decisions about what to do in the next release. I can't promise that we will include everything you are asking for in the next release - but we are working in this area and there will be improvements.
