I have two methods in my test class:
#Test
#Stories( "story1")
public void test01(){
}
#Test
#Stories( "story2")
public void test02(){
}
#Test
#Stories( "story1")
public void test03(){
}
To run tests Im using:
mvn clean test site
It will execute all test. But my question is, how to execute tests when I want to execute only tests with specific user story (ie. story1)
I know in python it can be done by
py.test my_tests/ --allure_stories=story1
But I don't know how to do it in java using maven
In Java there is no need for Allure to do such sort of things, because you can do it using your test runner, e.g. TestNG.
Just create Listener or BeforSuite which will check your environment variable e.g. -DallureStories and match it with ITestContext to disable tests not in your stories list.

I have setup an embedded mongo via flapdoodle (de.flapdoodle.embed).
Quite a lot of mongo operations hence i would like to run all of them as a suite and setup the mongo just once in testsuite.
Now when i run the test cases via mvn install , it seems to run the test cases individually.
Is there a way to run test cases only from suite and not as a class.
baeldung.com describes the use of JUnit 5 Tags, which are very well suited for your case.
You can mark tests with two different tags:
#Test
#Tag("MyMongoTests")
public void testThatThisHappensWhenThatHappens() {
}
#Test
#Tag("MyTestsWithoutMongo")
public void testThatItDoesNotHappen() {
}
And execute either set in a suite, e.g.
#IncludeTags("MyMongoTests")
public class MyMongoTestSuite {
}
In your case, the tests could be categorized by whether Mongo is in the application context or not. So, theoretically, it might be possible to create a JUnit 5 Extension to add the tag. That would be the more complex solution though.
i have a problem which occurs when using NetBeans 8.2 and JUnit.
Considering the following example:
Unit Test:
private MyClass myClass = new MyClass();
#Test
public void testSomething() {
myClass.testMethod();
}
// OTHER TEST EXISTING BUT THESE ARE TAGGED WITH #IGNORE
If I am using the following production code:
MyClass:
public class MyClass {
public void testMethod() {
System.out.print("test");
}
}
The "Unit test output" in NetBeans displays something like:
test
Testcase: testSomethingOther(mypackage.MyClassTest):SKIPPED
Testcase: testSomethingOther2(mypackage.MyClassTest):SKIPPED
-- other tests which are ignored / failed --
But I only want NetBeans to display my own "print" statements, and not some Test details.
If i am using the "println" function, it works as as planned (no test details are written to output console).
What is the problem here?
You're using the annotation #Test which implies that you're probably using JUnit, TestNG or another Testing framework. If you don't want to see your framework's prints either check if there's a configuration setting / flag that you can pass that turns it off or stop using it and find another way to run your tests.
I am having a problem, one test class seems to be interfering with the other in my test suite.
I have a suite, which executes two classes, one is called MergeTestSuite.java (which is another Suite), and the other is called RecordTest.java.
RecordTest extends one class already tested by MergeTestSuite.java
I created another suite as follows:
#RunWith(Suite.class)
#Suite.SuiteClasses( {
MergeTestSuite.class,
RecordTest.class
})
public class CoreTestSuite {
#BeforeClass
public static void install() throws Throwable {
RegistryUtils.cleanupResources();
}
}
Both MergeTestSuite.class and RecordTest.class run fine individually. If I run CoreTestSuite, the second test will fail, unless I remove MergeTestSuite.class from the list.
A Junit TestSuite provides extra features for multiple tests. For instance, you can control the order in which the tests run and you can also combine multiple test suites into another suite. I think this older doc from Junit 3.1.8 describes it best.
When writing code that interacts with external resources (such as using a web service or other network operation), I often structure the classes so that it can also be "stubbed" using a file or some other input method. So then I end up using the stubbed implementation to test other parts of the system and then one or two tests that specifically test calling the web service.
The problem is I don't want to be calling these external services either from Jenkins or when I run all of the tests for my project (e.g. "gradle test"). Some of the services have side effects, or may not be accessible to all developers.
Right now I just uncomment and then re-comment the #Test annotation on these particular test methods to enable and disable them. Enable it, run it manually to check it, then remember to comment it out again.
// Uncomment to test external service manually
//#Test
public void testSomethingExternal() {
Is there is a better way of doing this?
EDIT: For manual unit testing, I use Eclipse and am able to just right-click on the test method and do Run As -> JUnit test. But that doesn't work without the (uncommented) annotation.
I recommend using junit categories. See this blog for details : https://community.oracle.com/blogs/johnsmart/2010/04/25/grouping-tests-using-junit-categories-0.
Basically, you can annotate some tests as being in a special category and then you can set up a two test suites : one that runs the tests of that category and one that ignores tests in that category (but runs everything else)
#Category(IntegrationTests.class)
public class AccountIntegrationTest {
#Test
public void thisTestWillTakeSomeTime() {
...
}
#Test
public void thisTestWillTakeEvenLonger() {
....
}
}
you can even annotate individual tests"
public class AccountTest {
#Test
#Category(IntegrationTests.class)
public void thisTestWillTakeSomeTime() {
...
}
Anytime I see something manually getting turned on or off I cringe.
As far as I can see you use gradle and API for JUnit says that annotation #Ignore disables test. I will add gradle task which will add #Ignore for those tests.
If you're just wanting to disable tests for functionality that hasn't been written yet or otherwise manually disable some tests temporarily, you can use #Ignore; the tests will be skipped but still noted in the report.
If you are wanting something like Spring Profiles, where you can define rulesets for which tests get run when, you should either split up your tests into separate test cases or use a Filter.
You can use #Ignore annotation to prevent them from running automatically during test. If required, you may trigger such Ignored tests manually.
#Test
public void wantedTest() {
return checkMyFunction(10);
}
#Ignore
#Test
public void unwantedTest() {
return checkMyFunction(11);
}
In the above example, unwantedTest will be excluded.
What is the best way run a lot of integration tests using JUnit?
I crudely discovered that the code below can run all the tests... but it has a massive flaw. The tearDown() method in each of those classes is not called until they have all been run.
public class RunIntegrationTests extends TestSuite {
public RunIntegrationTests(){
}
public static void main (String[] args){
TestRunner.run(testSuite());
}
public static Test testSuite(){
TestSuite result = new TestSuite();
result.addTest(new TestSuite(AgreementIntegrationTest.class));
result.addTest(new TestSuite(InterestedPartyIntegrationTest.class));
result.addTest(new TestSuite(WorkIntegrationTest.class));
// further tests omitted for readability
return result;
}
}
The classes being run connect to the database, load an object, and display it in a JFrame. I overrode the setVisible method to enable testing. On our build machine, the java vm runs out of memory when running the code above as the objects it has to load from the database are pretty large. If the tearDown() method was called after each class finished it would solve the memory problems.
Is there a better way to run them? I'm having to use JUnit 3.8.2 by the way - we're still on Java 1.4 :(
Not sure if this is the problem, but according to the JUnit Primer you should just add the tests directly, instead of using the TestSuite:
result.addTest(new AgreementIntegrationTest()));
result.addTest(new InterestedPartyIntegrationTest()));
result.addTest(new WorkIntegrationTest()));
That's very strange. setUp and tearDown should bookend the running of each test method, regardless of how the methods are bundled up into suites.
I typically do it slightly differently.
TestSuite suite = new TestSuite( "Suite for ..." ) ;
suite.addTestSuite( JUnit_A.class ) ;
suite.addTestSuite( JUnit_B.class ) ;
And I just verified that tearDown was indeed being called the correct number of times. But your method should work just as well.
Are you sure tearDown is properly specified -- e.g. it's not "teardown"? When you run one test class on its own, is tearDown properly called?
