I have few JUnit Tests and I want to decide which one to use at runtime. I checked previous answers at SO and I ended up creating Test Suite dynamically.
This class is where my application starts. I have CustomTestSuite class and Main class adds Tests to my custom suite.
public class Main {
public static junit.framework.TestSuite suite()
{
CustomTestSuite suite = new CustomTestSuite();
suite.addTest(new JUnit4TestAdapter(BTest.class));
suite.addTest(new JUnit4TestAdapter(ATest.class));
return suite;
}
}
CustomTestSuite.java
public class CustomTestSuite extends TestSuite {
#BeforeClass
public static void setUp() throws Exception {
System.out.println("Before class test");
}
#After
public void tearDown() throws Exception {
System.out.println("After class test");
}
}
My ATest and BTest are simple Test classes, I will just show ATest as sample:
public class ATest{
#Test
public void testMethod() {
System.out.println("testMethod");
}
}
When I start running my project from Main class, it is expected to run the method with #BeforeClass first, do testing, and then run the method with #AfterClass annotation.
Tests are working fine but it skips setUp method and tearDown method. I tried #Before and #BeforeClass annotations both.
I am confused with suite structure. Any help would be appreciated.
Thanks
#Before and #BeforeClass are supposed to be used in Test class not in TestSuite. If need to have common setUp and tearDown for more than one Test class, then put those both methods in a super class and extend that super by ATest and BTest test classes. And also the Suite can be built and run simply with #RunWith and #SuiteClasses annotations and the CustomTestSuite class is not needed.
So the changes are as below.
The CustomTestSuite becomes TestSuper
public class TestSuper {
#BeforeClass
public static void setUp() throws Exception {
System.out.println("Before class test");
}
#After
public void tearDown() throws Exception {
System.out.println("After class test");
}
}
Now the ATest extends TestSuper
public class ATest extends TestSuper {
#Test
public void testMethod() {
System.out.println("testMethod");
}
}
Similarly BTest also should extend TestSuper.
Simply add #RunWith and #SuiteClasses annotations to Main class as below and run Main.
#RunWith(Suite.class)
#SuiteClasses({ATest.class, BTest.class})
public class Main {
}
Have a go with these changes.

I try to mock a static class PowerMockito.mockStatic(Static.class);. When #RunWith(PowerMockRunner.class), the code runs successfully but when I use #ExtendWith(MockitoExtension.class), it throws org.powermock.api.mockito.ClassNotPreparedException. Is it possible to mock a static class with #ExtendWith(MockitoExtension.class)?
This is my setup
#RunWith(PowerMockRunner.class)
#PrepareForTest({SmeRestClient.class})
public class PreScreeningServiceImplTest extends PreScreeningServiceImplTestHelper {
#Before
public void setup() {
PowerMockito.mockStatic(Static.class);
}
}
#RunWith(JUnitParamsRunner.class)
#ExtendWith(MockitoExtension.class)
#PrepareForTest(SmeRestClient.class)
public class PreScreeningServiceImplTest extends PreScreeningServiceImplTestHelper {
#Before
public void setup() {
PowerMockito.mockStatic(Static.class);
}
}
Full error code
org.powermock.api.mockito.ClassNotPreparedException:
The class com.ime.restful.Static not prepared for test.
To prepare this class, add class to the '#PrepareForTest' annotation.
In case if you don't use this annotation, add the annotation on class or method level.
I'm writing an application test with Junit5 and TestFX.
My intention is that the main test class relaunches the application after each test. As far as I know, I shall use the annotation #BeforeEach, and it didn't work for me.
Here is my test class:
#FixMethodOrder(MethodSorters.NAME_ASCENDING)
public class MainTest extends ApplicationTest implements FxRobotInterface {
Logger loggerGuiTesting = LoggerManager.getInstance().getLogger(LoggerType.GUI_TESTING);
#BeforeEach
#Override
public void start(final Stage stage) {
StartMain.getInstance();
this.loggerGuiTesting.log(Level.INFO, "Application starts!");
}
#AfterAll
public void endApplication() {
new ExitGuiTest().run(); // That's my internal test framework
}
#Test
public void atestIfOpeningScreenIsThere() {
verifyThat("#imageViewSplashScreenLogo", NodeMatchers.isNotNull());
verifyThat("#progressBarSplashScreen", NodeMatchers.isNotNull());
verifyThat("#labelSplashScreenVersion", NodeMatchers.isNotNull());
verifyThat("#labelSplashScreenDate", NodeMatchers.isNotNull());
this.loggerGuiTesting.log(Level.INFO, "testIfOpeningScreenIsThere, succeeded!");
}
#Test
public void btestIfRadioButtonOneExist() {
assertThat("#sourcesOneRadioButton", is("#sourcesOneRadioButton"));
this.loggerGuiTesting.log(Level.INFO, "testIfRadioButtonOneExist, succeeded!");
}
#Test
public cnextTest() {
new StartAnotherGuiTest().run();
this.loggerGuiTesting.log(Level.INFO, "anotherTest, succeeded!");
}
}
The question is: how can I relaunch the application after each test?
It is difficult to answer without taking a look at the StartMain class. It looks like you are using a singleton pattern there. If thats the case I would create a new method in StartMain that sets the singleton instance to null so when getInstance is called again, it has to be re-created:
#After //This should be executed after each test
public void destroyApp()
{
StartMain.getInstance().destroy();
}
My #Before and #After methods are not picking up by Junit
public class TestSetup {
#Before
public void browserSetUp() {
// code for before a test
}
#After
public void tearDown() {
// code after a test
}
}
In Another class file I have defined
public class Steps{
#Step
public void step1() {
//Code for step 1
}
#Step
public void step2() {
// Code for Step 2
}
}
Finally I am calling those steps for my Test
public class Tests {
Steps step = new Steps();
#Test
public void TC_0001 {
step.step1();
step.step2();
}
}
#Test method are getting executed but the #Before and #After methods are not executing before #Test method.Do I have to include the TestSetup class to somewhere ? Any help will be appreciated.
**Thought 1: As I am using Maven to build, my #Before #After methods resides in a class (TestSetup.java - Name is not ending with *Test.java and may be thats why Maven is not picking it up for execution?
#Before and #After are used in the same class that your test is running. You should put this methods on your test class:
public class Tests {
Steps step = new Steps();
#Test
public void TC_0001 {
step.step1();
step.step2();
}
#Before
public void browserSetUp() {
// code for before a test
}
#After
public void tearDown() {
// code after a test
}
}
#Before and #After are only executed before a single test, if they are defined in the same class as the #Test. In your case, the TestSetup class contains no tests. So either you let Test inherit from TestSetup or you create a rule that is executed "around" your test.
I have a little problem here, and I don't know how to solve it.
I have a class which have to make tests for some JSF beans.
In order to achieve that, I used PowerMock with Mockito for mocking the FacesContext, RequestContext and another static methods which are used inside the JSF beans.
#PrepareForTest(ClassWithStaticMethods.class)
#RunWith(PowerMockRunner.class)
#FixMethodOrder(MethodSorters.NAME_ASCENDING)
public class MyTestingClass extends SomeTestBaseClass{
#BeforeClass
public static void init() throws Exception{
//mocking the FacesContext and others
}
#Test
public void test0001Create(){}
#Test
public void test0002Edit(){}
#Test
public void test0003Delete(){}
}
The SomeTestBaseClass, nothing complicated.
public abstract class SomeTestBaseClass {
#BeforeClass
public static void setUpBeforeClass() throws Exception {
//...
}
#AfterClass
public static void tearDownAfterClass() throws Exception {
//...
}
}
The problem is that the order of tests is ignored (even with the FixMethodOrder annotation). If I remove PowerMockRunner (and the RunWith annotation), the order is kept but the mocking for static (and void) methods doesn't work.
But leaving the class with PowerMockRunner, the annotation #FixMethodOrder is ignored, totally.
I even tried with MockitoJUnitRunner, and here the order of tests is kept, but the mocking for static (and void) methods isn't done.
Does anyone have any idea why it is happening?
Thanks
I had the same problem getting them to run in the right order.
I solved it by using the #PowerMockRunnerDelegate annotation.
In my test class annotations:
#FixMethodOrder(MethodSorters.NAME_ASCENDING)
#RunWith(PowerMockRunner.class)
I added #PowerMockRunnerDelegate(JUnit4.class):
#FixMethodOrder(MethodSorters.NAME_ASCENDING)
#RunWith(PowerMockRunner.class)
#PowerMockRunnerDelegate(JUnit4.class)
They now run in the expected order.
I believe this works because then it's not PowerMock that's running the tests, but JUnit 4 itself.
Like a workaround: Create a new method (let's say 'testAll'), put #Test annotation just for this (remove the #Test annotation from the rest of the methods), and then, call your testing methods inside of the annoted method.
Dirty, but it works.
#PrepareForTest(ClassWithStaticMethods.class)
#RunWith(PowerMockRunner.class)
#FixMethodOrder(MethodSorters.NAME_ASCENDING)
public class MyTestingClass extends SomeTestBaseClass{
#BeforeClass
public static void init() throws Exception{
//mocking the FacesContext and others
}
#Test
public void testAll(){
this.test0001Create();
this.test0002Edit();
this.test0003Delete();
}
public void test0001Create(){}
public void test0002Edit(){}
public void test0003Delete(){}
}
Please try to change sequence:
#FixMethodOrder(MethodSorters.NAME_ASCENDING)
#RunWith(PowerMockRunner.class)
#PrepareForTest(ClassWithStaticMethods.class)
I don't know why it doesn't work with the PowerMockRunner annotation but instead you could use a PowerMockRule
#FixMethodOrder(MethodSorters.NAME_ASCENDING)
public class MyTestingClass extends SomeTestBaseClass {
#Rule
public PowerMockRule rule = new PowerMockRule();
#BeforeClass
public static void init() throws Exception {
// mocking the FacesContext and others
}
#Test
public void test0001Create() {
}
#Test
public void test0002Create() {
}
#Test
public void test0003Create() {
}
}
I have the following code:
#BeforeClass
public static void setUpOnce() throws InterruptedException {
fail("LOL");
}
And various other methods that are either #Before, #After, #Test or #AfterClass methods.
The test doesn't fail on start up as it seems it should. Can someone help me please?
I have JUnit 4.5
The method is failing in an immediate call to setUp() which is annotated as #before.
Class def is :
public class myTests extends TestCase {
do NOT extend TestCase AND use annotations at the same time!
If you need to create a test suite with annotations, use the RunWith annotation like:
#RunWith(Suite.class)
#Suite.SuiteClasses({ MyTests.class, OtherTest.class })
public class AllTests {
// empty
}
public class MyTests { // no extends here
#BeforeClass
public static void setUpOnce() throws InterruptedException {
...
#Test
...
(by convention: class names with uppercase letter)
the method must be static and not directly call fail (otherwise the other methods won't be executed).
The following class shows all the standard JUnit 4 method types:
public class Sample {
#BeforeClass
public static void beforeClass() {
System.out.println("#BeforeClass");
}
#Before
public void before() {
System.out.println("#Before");
}
#Test
public void test() {
System.out.println("#Test");
}
#After
public void after() {
System.out.println("#After");
}
#AfterClass
public static void afterClass() {
System.out.println("#AfterClass");
}
}
and the ouput is (not surprisingly):
#BeforeClass
#Before
#Test
#After
#AfterClass
Make sure you imported #Test from the correct package.
Correct package: org.junit.Test
Incorrect pacakge: org.junit.jupiter.api.Test
Please note that this is a solution for: If your #Before, #Atter, etc did not get called at all.
Make sure that :
Your test class doesn't inherits from TestCase
The #BeforeClass method is static
You don't have more than one #BeforeClass method in test class hierarchy (only the most specialized #BeforeClass method will be executed)
Check your imports.
#Before
#After
#BeforeClass (this should be static)
#AfterClass (this should be static)
and #Test annotations should import from same path.
In order that the before annotated function will run , I had to do the following:
If you use Maven , add a dependency to Junit 4.11+:
<properties>
<version.java>1.7</version.java>
<version.log4j>1.2.13</version.log4j>
<version.mockito>1.9.0</version.mockito>
<version.power-mockito>1.4.12</version.power-mockito>
<version.junit>4.11</version.junit>
<version.power-mockito>1.4.12</version.power-mockito>
</properties>
and the dependency:
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>${version.junit}</version>
<scope>test</scope>
</dependency>
.
.
.
</dependencies>
Make sure your Junit Test class is not extending The TestCase class, since this will cause overlapping with Older version:
public class TuxedoExceptionMapperTest{
protected TuxedoExceptionMapper subject;
#Before
public void before() throws Exception {
subject = TuxedoExceptionMapper.getInstance();
System.out.println("Start");
MockitoAnnotations.initMocks(this);
}
}
