I have a Junit test class with multiple #Test methods in it that I need to run in order. If there is an exception thrown in a method I would like to stop entire test case and error out, but all of the rest of the test methods running.
public class{
#Test{
//Test1 method`enter code here`
}
#Test{
//Test2 method
}
#Test{
//Test3 method
}
}
If Test1 method fails then don't run other Tests
Note: All are independent tests
Unit tests should be designed to run independently of one another. The order of execution cannot be guaranteed. You should redesign your test class so that the order is not important.
Without further information it's hard to advise you specifically. But it may help to have an #before method, which checks for some precondition before running each test. If you included an Assume.assumeTrue(...) method call, then your test could be skipped if the condition fails?
As discribed here, JUnit 4.11 supports the ordered execution with the Annotation #FixMethodOrder, but the others are right, all tests should be independent of each other.
At the end of a test you can set a global success flag. This flag will be tested at the begining of each test. If the flag is not set by the end of one test(because it fails before finishing) all other tests will fail too.
Example:
#FixMethodOrder(MethodSorters.NAME_ASCENDING)
public class ConsecutiveFail{
private boolean success = true;
#Test
public void test1{
//fist two statements in all tests
assertTrue("other test failed first", success);
success = false;
//do your test
//...
//last statement
success = true;
}
#Test
public void test2{
//fist two statements in all tests
assertTrue("other test failed first", success);
success = false;
//do your test
//...
//last statement
success = true;
}
}
I was able to achieve what you are looking with intellij idea IDE, I am using community edition.
Go to Edit Configuration in the class where test methods available.( Run --> Edit Configurations)
Select Test kind as "Class"
as in the below Image.
When you run the Class Test it will execute all #Test Annotated methods inside the class as in below Picture.
If you need the consequence to be kept and failing a test not to fail the whole set, put all such tests in one and test by assume.
Here's example for TESTNG how to specify test running order:
#Test(priority = 1)
public void test1(){}
#Test(priority = 2)
public void test2(){}
#Test(priority = 3)
public void test3(){}

Here is the relevant code in my test:
private MockedStatic<MyDAO> myDAOStaticMock;
#Captor
ArgumentCaptor<SomeInput> someInputCaptor;
#Before
public void before() {
myDAOStaticMock = Mockito.mockStatic(MyDAO.class);
}
#After
public void after() {
myDAOStaticMock.close();
}
#Test
public void test() {
thingImTesting.methodThatCallsDaoStatically();
myDAOStaticMock.verify(() -> MyDao.staticMethod(someInputCaptor.capture()), times(2));
}
When I run this test in intellij, it almost always works. When it runs through our build system, it fails every time. The error is that there is 0 interaction with this mock.
What might be the problem with this particular verify, when all of the rest of my static checks work fine?
Edit: I was wrong about the reason for the issue and the static checks were not related. See my answer for more information.
I was wrong about the reason these tests failed in the build system. The unit test I wrote called DateTime.now() which has a different result depending on the timezone of where you are running the code. My build system was running the code in a different timezone, so the test failed in that context.
By being explicit about time zone in my unit test (e.g. DateTime.now().withZone(whatever)), I was able to fix the issue.
I have simple Android application with some espresso tests.
I want to write some base class so all of my test classes will inherit its #beforeClass and #afterClass methods, but the problem is when I do it like code example below, JUnit doesn't see any tests at al. I got Empty test suite. message. What's the problem?
Code example:
public class RealmTest {
protected static Realm realm;
#BeforeClass
public static void beforeClass() {
realm = Realm.getDefaultInstance();
realm.setAutoRefresh(true);
}
#AfterClass
public static void afterClass() {
realm.close();
}
}
#RunWith(AndroidJUnit4.class)
public class MainActivityTest extends RealmTest {
#Rule
public IntentsTestRule<MainActivity> activityTestRule = new IntentsTestRule<>(MainActivity.class);
#Test
public void startedFine() {
assertNotNull(realm);
onView(withId(R.id.button)).perform(click());
intended(hasComponent(new ComponentName(getTargetContext(), EducationActivity.class)));
}
}
If I'll run all tests, tests from MainActivityTest won't run.
Thanks for your help, pls say if some additional info is needed.
Guessing: the JUnit environment is not looking for static methods. So maybe you simply drop that keyword from your base methods (guess you could keep your Realm static nonetheless; I assume you really only want one of those).
But then, another suggestion: don't use inheritance for test cases.
The point that makes test cases valuable to you is: they should quickly allow you to find and fix bugs in your production code.
But when your "setup" is hidden from your testcases - because things are not only happening in some #Before method ... but in a #Before method somewhere, in some different class ... well, that can seriously increase the time you will need to understand a failing testcase. Because: instead of just studying your test case, you find yourself digging around within test code in order to understand what exactly is happening besides the code in that failing test method itself!
Thus: be really careful to balancing "code duplication" versus "test case is easy to understand" aspects!
I am using TestNG with Selenium WebDriver, the framework that I use has one base class which has BeforeClass method and all the Suite classes extend from this base class and have overriden BeforeClass methods as shown.
public BaseClass{
#BeforeClass
public void preConditions{
//primary actions like opening browser and setting preferences
}
}
public TestSuiteClass extends BaseClass{
#BeforeClass
#Override
public void preConditions(){
super.preCnditions();
//specific preconditions required by test suite
}
}
The problem I am have is, if an overridden method is failing for any reason, all the test suits/cases gets skipped and entire test execution stops.
How to stop this from happening?
If something fails in #Before... annotated procedure the tests will be skipped instead of failing, because the problem is not with your test cases, but with the process before them. So it looks like your car cannot cross the river on a broken bridge, but it's not your car's fault.
If you really want to do some hacking about it, you can find ideas here!
You can find a way around this, but you need to consider if you realy want to do it. The idea of the method with #BeforeClass annotation is to set relevant data for the test (you even called it preConditions). If it fails, the test won't pass anyway.
One way to do it is to remove the #BeforeClass annotation and call the method from the test itself
public TestSuiteClass etends BaseClass {
public void customPreConditions() {
super.preCnditions();
}
#Test
publuc void someTest() {
customPreConditions();
// do the test
}
}
The test will continue even if customPreConditions() is not successful.
I have a test that does a cycle to run the same test but with different inputs. The problem is that when one assert fails, then the test stops, and it is marked as if one test failed.
Here is the code:
#Test
public void test1() throws JsonProcessingException {
this.bookingsTest(Product.ONE);
}
#Test
public void test2() throws JsonProcessingException {
this.bookingsTest(Product.TWO);
}
public <B extends Sale> void bookingsTest(Product product) {
List<Booking> bookings = this.prodConnector.getBookings(product, 100);
bookings.stream().map(Booking::getBookingId).forEach((bookingId) -> {
this.bookingTest(bookingId);
});
}
public <B extends Sale> void bookingTest(String bookingId) {
...
// Do some assert:
Assert.assertEquals("XXX", "XXX");
}
In that case, the methods test1 and test2, execute as two different tests, but inside them, I do a cycle to check some stuff on every item that is returned by the collection. But what I want is to make that test on each item to be treated as a different one, so that if one fails, the others continue executing and I can see which one failed and how many failed over the total.
what you described is parameterized testing. there is plenty of frameworks that may help you. they just have different simplicity to power ratio. just pick the one that fits your needs.
junit's native way is #Parameterized but it's very verbose. other junit plugins that you may find useful are zohhak or junit-dataprovider. if you are not enforced to use junit and/or plain java, you can try spock or testng.
I'm testing different parts of a miniature search engine, and some of the JUnit tests are leaving entries in the index that interfere with other tests. Is there a convention in JUnit/Maven for clearing objects between tests?
There are 2 particular annotations that can help you with this, and are intended to be used in cases such as yours:
#After defines that a certain method must be executed after every #Test, while #AfterClass is the method to execute once the entire test class has been executed. Think of the latter as a last cleanup method to purge any structures or records you've been using and sharing between tests so far.
Here is an example:
#After
public void cleanIndex() {
index.clear(); //Assuming you have a collection
}
#AfterClass
public void finalCleanup() {
//Clean both the index and, for example, a database record.
}
Note: They have their counterparts (#Before and #BeforeClass) that to exactly the opposite by invoking the related methods before a #Test method and before starting to execute the #Tests defined on that class. This ones are the setUp used in previous versions of JUnit.
If you can't use annotations, the alternative is to use the good old tearDown method:
public void tearDown() {
index.clear(); //Assuming you have a collection.
}
This is provided by the JUnit framework and behaves like a method annotated with #After.
You should make use of the #Before annotation to guarantee that each test is running from a clean state. Please see: Test Fixtures.
Inside of your junit testing class, you can override the methods setup and teardown. setup will run before every one of your tests while teardown will run after every single junit test that you have.
ex:
public class JunitTest1 {
private Collection collection;
//Will initialize the collection for every test you run
#Before
public void setUp() {
collection = new ArrayList();
System.out.println("#Before - setUp");
}
//Will clean up the collection for every test you run
#After
public void tearDown() {
collection.clear();
System.out.println("#After - tearDown");
}
//Your tests go here
}
This is useful for clearing out data inbetween tests, but also allows you to not have to reinitialize your fields inside of every single test.
