I have several #ParameterizedTest test method in my class.
I have static #BeforeAll method which runs before all #ParameterizedTest test methods once.
Now I need a mechanism to run a certain '#Before' method before each #ParameterizedTest test method (NOT before each scenario of #ParameterizedTest test but before test method annotated as #ParameterizedTest).
The issue is that #BeforeEach annotation will run your 'before' method before each scenario of #ParameterizedTest test but I need to run that once.
Any ideas?
I have a similar problem, you can use #Nested for this

I wish to run a method with #BeforeClass annotation twice (or more). Is there a way to do so with TestNG?
Like: #Test(invocationCount = 2)?
No there is no such provision available in TestNG.
#BeforeClass is a configuration method that is designed to run exactly once before any #Test methods within a particular class get executed.
So there's no way of altering its behavior.
I have about 5 different classes with JUnit tests (selenium tests).
I need a way to teardown the webdriver at the end of the program.
So I need to know where to put the #AfterClass and how to pass the driver to it so it can be closed.
I thought of creating a test suit and implement the &AfterClass tearDownClass() there. But I'm not sure how to pass the driver to it to close.
You can use below code
[OneTimeTearDown]
public void SetupTestTeardown()
{
KillDriver();
Assert.AreEqual("", verificationErrors.ToString());
}
The OneTimeTearDown attribute is inherited from any base class. Therefore, if a base class has defined a OneTimeTearDown method, that method will be called after any test methods in the derived class.
You may define a OneTimeTearDown method in the base class and another in the derived class. NUnit will call base class OneTimeTearDown methods after those in the derived classes.
Add #BeforeClass to your superclass. Initiate the driver in that. Due to this, the test classes will also inherit the driver.
Add the driver teardown in your superclass in #AfterClass
I am writing a test class in java using spring and junit (actually I have "#RunWith(SpringJUnit4ClassRunner.class)" at the bottom of my class).
there is a method with #Before annotation that I want it not to be run before a particular test method(but not the rest). how can I do this?
thanks
You have a few options:
Refactor to put that one test in a new test class which doesn't have #Before.
Refactor to put that one test in a new test class extending the original one that overrides #Before to do nothing.
Refactor to have all the other methods call the before method explicitly and remove the #Before annotation (I don't recommend you go with this one)
I have a bit of a special situation. Basically I have a unit test, annotated with #Test, and inside that test I need to execute a Cucumber JVM test class.
Why? Long story. Something to do with classloaders and RoboGuice, it's not very important but it does impose limits on what I can and cannot do.
Here's the test method:
#Test
public void runCucumberFeature() throws Exception {
Cucumber cucumber = new Cucumber(MyCucumberTest.class);
cucumber.run(new RunNotifier());
}
MyCucumberTest is a class I have created, and annotated like this:
//#RunWith(Cucumber.class)
#Cucumber.Options(format = {"pretty", "html:target/cucumber"}, strict=true)
public class MyCucumberTest {
// Empty, as required by Cucumber JVM
}
Why have I commented out the #RunWith annotation? Because if I don't, the Cucumber test runner will pick up the test and run it, which I don't want because I am running the test manually.
The problem is that the above doesn't work. It looks like Cucumber is finding the feature files, it is verifying that MyCucumberTest contains the #Givens etc, it even prints out the test as if it was running it.
But it doesn't. No code is executing inside the #Given, #When and #Then methods. I'm not sure why this is, but I have a vague idea that the Cucumber JVM test runner doesn't want to execute the code because the class isn't annotated with #RunWith.
Can anyone help?
I can't provide the solution you're looking for, but....
... have you considered tagging the test that you want to run manually (e.g. with #Manual)?
Then you could uncomment your #RunWith annototation and exclude the manual test by adding --tags ~#Manual to your Cucumber-JVM invocation.
In your manual JUnit invocation you could add --tags #Manual
I'd like a junit runner that executes all #Before methods, then all #Test methods, then all #After methods.
This is how my System-Tests work. The #Before methods are run, to setup the test data and scenarios. The application is started. Then the #Test methods are run with the application running in the background. Those #Test methods can change data or respond to the application. Then the framework waits for the application to finish up. Afterward, the #After methods are run to verify the test results.
I already use junit annotations, assertion methods, and other various bits. But I just can't figure out how to use junits runners to execute test methods in this way. I couldn't make heads nor tails of the "Computer" interface in junit 4.8, or figure out how to apply Rules to this.
This isn't what JUnit does. JUnit has a design philosophy that emphasizes independent unit tests. As such, it isn't a natural framework for system tests. What you want to do fits nicely into TestNG (which as a design goal tries to straddle both unit and system tests).
In JUnit the #Before and #After are run before and after each test. You can shoehorn this kind of thing into JUnit using a Suite, which references all of your tests and is responsible for all setup and teardown, so the Suite's #BeforeClass and #AfterClass methods get run before and after the suite, which if you organize it correctly could be all of your system tests.
There are lot of organizational challenges in the code when it gets large with the JUnit approach, so I would suggest you consider and alternative framework if this is the bulk of what you want to do.
I think you can solve this by making only one actual test method, that just calls are your actual tests, which you do not declare as ssuch.
Kinda like:
#Before
public void beforeTest(){}
#After
public void afterTest(){}
#Test
public void test(){
test1();
test2();
test3();
}
public void test1(){}
public void test2(){}
public void test3(){}
