Usually I usethe annotation #FixMethodOrder(MethodSorters.NAME_ASCENDING) and my tests start by test001_nametest1, test002_nametest2, ..
With this method adding a test between existing test is problematic (because you have to rename all test after).
Is there a way to execute all junit test in the written order ?

The model zoo provided few pre-trained models with several datasets such like PASCAL VOC2012, Cityscapes, ...etc. I am trying to run it on my local and it works as well with validation set because of they are providing the code to convert train/validation set to tfrecord. However, I couldn't test DeepLabV3+ with test set.
Is there any way to run with test set?
Use [inference] and loop over all images.1
Student here. In JUnit 5, what is the best way to invoke a #Nested test class multiple times, but with slightly different state each time?
I see that JUnit 5 has an (experimental) #ParameterizedTest feature that is based on the (non-experimental) #TestTemplate feature, but both of those apply to test methods only, rather than nested test classes.
I have a heavy #Nested test class that needs to be invoked once for each value of an enum (preferably with a distinct #Tag value for each invocation), and I would prefer to avoid the "copy-and-paste" method of parameterization.
It is not currently possible to execute a test class multiple times in JUnit Jupiter.
To participate in the discussion, see the following issue: https://github.com/junit-team/junit5/issues/878
Currently If I write #Before method, it will be executed for each of tests present in the JUnit. However i want the following.
I need to have multiple #Before methods and only needed should be executed for each test.
Example:
#Before
setUpBeforeForTest1AndTest3()
#Before
setUpBeforeForTest2AndTest4()
For test1 and test2, setUpBeforeForTest1AndTest3() should be executed and for other tests setUpBeforeForTest2AndTest4 should be executed.
How i can acheive this?
you can not achieve that this way.
To do this, make 2 distinct test classes, one with test 1 and test 3, one other with test 2 and test 4.
If you have common methods needed in all your test classes either externalize them in a helper or make a super class (usually called 'TestBase' or something similar) providing them.
You can use Junit
#Rule TestName
Then in your
#Before, depending on the test method name, do something differently.
Let's say I have three JUnit test cases, namely TC1, TC2 and TC3. Is there a way to configure TeamCity or pom somehow, so that when I remote run, the order will be TC1 -> TC2 -> TC3 always?
Right now, because of unordering in test cases, all these tests start with the same functionality (for example: creating a user), which takes a pretty big amount of time. I would like to do that functionality in the first test case only (TC1 in this case). I am open for any other approaches also.
Thanks in advance.
maven-failsafe-plugin has an optional parameter, runOrder which is exactly what I wanted. You can set it to alphabetical and afterwards, you modify the name of your testcases, you are done.
I'm new to Junit. I want to write test cases for if condition,loops.
Do we have any guidelines or procedure to write test cases for if,loop conditions?
Can anyone explain with an example?
IF Age < 18 THEN WHILE Age <> 18
DO ResultResult = Result +1 AgeAge = Age +1 END
DO Print “You can start driving in {Result} years”
ELSE
Print “You can start driving now!”
ENDIF
You want one test case for each major scenario that your code is supposed to be able to handle. With an "if" statement, there are generally two cases, although you might include a third case which is the "boundary" of the two. With a loop, you might want to include a case where the loop is run multiple times, and also a case where the loop is not run at all.
In your particular example, I would write three test cases - one where the age is less than 18, one where the age is exactly 18, and one where the age is over 18. In JUnit, each test case is a separate method inside a test class. Each test method should run the code that you're testing, in the particular scenario, then assert that the result was correct.
Lastly, you need to consider what to call each test method. I strongly recommend using a sentence that indicates which scenario you're testing, and what you expect to happen. Some people like to begin their test method names with the word "test"; but my experience is that this tends to draw attention away from what CONDITION you're trying to test, and draws attention toward which particular method or function it is that you're testing, and you tend to get lower quality tests as a result. For your example, I would call the test methods something like this.
public void canStartDrivingIfAgeOver18()
public void canStartDrivingIfAgeEquals18()
public void numberOfYearsRemainingIsShownIfAgeUnder18()
From my understanding of writing in junit for java ,we were used to create a source code into different blocks is the code conventional,and used to pass the values as args to the function from the test cases so the values will steps into the block statements ,and passes the test cases .
For example you are having the variable as age by assuming as functionName(int age), for testing you should pass the integer from the test case as functionName(18) it will steps into the statements and will show you the status of the test case.Create test case for a testing class write test case for the functions
UseClass classObj=new UseClass();// it should be your class
#Test
public void testValidateAge() {
classObj.validateAge("20");
assertEquals(200,"");
}
Correct me if 'm wrong :)
