I have several classes each containing several methods annotated with #Test. The classes are not extending TestCase. Now I want to
write a main that executes all these methods (for command line use)
create a class that can be "Run as -> JUnit Test" in Eclipse executing all these methods
Since the classes are no TestCases I can't just add them to a suite. Also extending TestCase is not an option because the test methods are just annotated and their names don't start with 'test'.
How can I do this?
Try this:
#RunWith(Suite.class)
#Suite.SuiteClasses({
Test1.class,
Test2.class,
Test3.class,
Test4.class
})
public class YourTestSuite {
}
You can set up run configurations for a project. Right click on your project. Then selecte 'Run as' -> 'Run configurations'. Within that you can select run all tests
What Eugene posted works if you have a small number of classes. If you want all the tests in a certain package pattern, Classpath Suite lets you specify this with patterns instead of listing them all out.

I have a testng.xml file and i have three classes and all three have tests with priority from 1 to 4(#Test(priority=1 to 4)). On running it the tests with priority 1 from different classes run first and affect the flow of my test.What kind of testng annotation can I use to avoid this?
#Test(priority=1) given in multiple classes
use preserve order
<test name="Test" preserve-order="true">
So that all classes specified in testng.xml will run in specified order and then in each class methods will run as per priority.
In testng, the order of the classes mentioned in the testng.xml doesn't matter if you have the priority set in the tests inside those classes. The tests will run according to the priorities (priority=1 tests will run first and then priority=2 and further on).
To solve the above issue, you need to remove the priorities from the tests inside the classes and then put the classes in the testng in the order you want to execute those classes and put <preserve-order="true"> in the testng xml.
If you want to run the tests inside a class also in a particular order, then you can use dependsOnMethods between the tests mentioned inside the class like:
#Test(dependsOnMethods = {"parentTest"})
public void childTest() {
}
#Test
public void parentTest() {
}
In the above case, when the parentTest() pass only then the childTest() will execute.
I have set of Junit test suites. All are working fine in eclipse.
In the test suites one test suite we will pass some System properties.
But those modified system properties should not propagate to other test suites So i just put those only in setup method like below,
#BeforeClass
public static void setUp() {
System.setProperty("public", "publicfolder");
System.setProperty("private", "privatefolder");
}
But this is working fine in eclipse only. While running it outside all other test suites are working fine except the above one.
I know to pass system properties in gradle in build file. but how could i pass those system properties to only one test suite instead of all thats my question here.
You could add another Test task so there's two in total. Each could have a different filter to run separate test suites and each could pass different system properties.

I want to test methods of Java classes using JUnit. Therefore, I use Eclipse and create a source folder "TestCases" which contains a package with the name "test" that should be the place where I want to put the JUnit test cases.
The whole directory set up is shown in the following pic:
My problem is, when I right-click on "test" and go to "JUnit Test Case", and write for example "ASTAnyExprTest"(see (1) in the following pic), and go to "Browse" (see (2)) and type "ASTAnyExpr" (see (3) ) to set the name of the class under test, then I see only a blank space (no class to choose).
So, I must have a path-problem, I thought. My first idea was to copy all classes to the package "test". But then I need to modify and adjust all dependencies in the classes.
So is there a better solution for that ?
best regards,
I am using junit with eclipse to write function tests.
When running an individual test it runs in the order that I have them set within the class.
Eg.
testCreateUser
testJoinUserToRoom
testVerify
testDeleteUser
However when I run this test as part of a suite, (so in a package) the order is random.
It will for example do the verify, then delete user then joinuserToRoom then Createuser.
My tests within the suite are not dependent on each other. However each individual test within a test is dependent on them being run in the correct order.
Is there any way I can achieve this?
Thanks.
You can't guarantee the order of execution of test methods in JUnit.
The order of execution of test classes within a suite is guaranteed (if you're using Suite), but the order of execution if the test classes are found by reflection isn't (for instance, if you're running a package in Eclipse, or a set of tests from maven or ant). This may be definable by ant or maven, but it isn't defined by JUnit.
In general, JUnit executes the test methods in the order in which they are defined in the source file, but not all JVMs guarantee this (particulary with JVM 7). If some of the methods are inherited from an abstract base test class, then this may not hold either. (This sounds like your case, but I can't tell from your description).
For more information on this, see my answer to Has JUnit4 begun supporting ordering of test? Is it intentional?.
So what can you do to fix your problem? There are two solutions.
In your original example, you've actually only got one test (verify), but you've got 4 methods, two setup (createUser, joinUserToRoom) and one teardown (deleteUser). So your first option is to better define your test cases, using a TestRule, in particular ExternalResource. ExternalResource allows you to define before/after behaviour for a test, similar to #Before/#After. However, the advantage of ExternalResource is that you can factor this out of your test.
So, you would create/delete the user in your external resource:
public class UsesExternalResource {
#Rule
public ExternalResource resource= new ExternalResource() {
#Override
protected void before() throws Throwable {
// create user
};
#Override
protected void after() {
// destroy user
};
};
#Test
public void testJoinUserToRoom() {
// join user to room
// verify all ok
}
}
For me, this is simpler and easier to understand, and you get independent tests, which is a good thing. This is what I would do, but you will need to refactor your tests a bit. You can also stack these Rules using RuleChain.
Your second option, if you really want to introduce dependencies between your test methods, is to look at TestNG, in which you can define dependencies from one test to another.
If they have a 'correct' order, then they are not multiple tests, but a single test that you have incorrectly annotated as being multiple independent tests.
Best practise would to rewrite them in approved junit style (setup - act - verify), supported by #Before or #BeforeClass methods that did any required common setup.
Quick workaround would be to have a single #Test-annotated method that called the other test methods in sequence. That becomes something like the preferred alternative if you are using Junit not to do strict unit testing, but something more like scenario-driven systems testing. It's not necessarily the best tool for such use, but it does work perfectly well in some cases.
Then, what you would have so far is have a single test:
#Test public void testUserNominalLifeCycle(...
which could then, if you are feeling virtuous, be supplemented by extra new tests like
#Test public void testUserWhoNeverJoinsARoom(...
This question is tangentially related to How can I create JUnit stub methods in eclipse? but it doesn't answer my specific question.
Assuming you have an existing JUnit test case class, if you add a method to the target class (or choose to test a previously untested method), is there a way to tell Eclipse to generate the stub for the "new" method(s) in the existing TestCase without creating a new test case class?
Install the MoreUnit extension from the MarketPlace.
Open the package hierarchy panel.
Navigate down to the class that
you've modified.
Right click on the new method.
Select "Generate Test". The generated stub will appear in your ClassTest file.
My solution.
I simply go through the standard 'create JUnit test case'
Select file to test. -> New Junit test case
Go through the normal process in creating the test case, but only select those that you want new stubs for.
The file is created with the stubs, which I now copy into the existing test case file.
Delete the newly created test file class.
It's not the most efficient, but quicker than 'thick fingering' when you create them manually.

The usual working cycle with unit tests is to create the test case first
public void test_new_method() {
ClassUnderTest x = new ClassUnderTest();
x.NewMethod();
}
At that point Eclipse will give you a warning that the method "NewMethod" does not exist. Than you simply select a "Quick Fix" (Ctrl-1 or Ctrl-2 i'm not sure) to create the missing method in the class.
