I wanted to start project using TDD. Created the test directory and later changed it to package that is integrated with src direcotry. In both cases I get the same error:
Class not found: "tests.objectsTest"
I tried different techniques of importing JUnit jar and none solved problem. Also I tried to rename my test class but it gives no solutons whatsoever.
It seems that IntelliJ or JUnit changes name of the test class. Shouldn't it be objectsTest.tests?
I am using JUnit version 4.12 and latest IntelliJ EAP.
This is my project structure:
Project:
-.idea
-src
-logic
-objects
-tests
-test
-test.java
src and tests are directories marked as Source and Test. Every package except test is empty. On my other PC with IntelliJ Community Edition everything works fine but on EAP there is this bug. Unfortunatelly I have to use EAP.
test.java code:
package test;
import org.junit.Test;
public class test {
#Test
public void canCreateInhabitant(){
}
}
Have you checked if you have the JUnit plugin enabled? I (foolishly, shame!) disabled it at some point and was unable to get IDEA to run my tests until I remembered to turn the plugin back on...
Check the root directory of your classes. It must be marked as source (for java classes) or test (for java test classes).
It seems that your directory is not well marked in IntelliJ.
I did a simple test and put it on github.
It's the absolute simplest of tests but it works great, standing inside the test class pressing shift+ctrl+t will run the test.
Go ahead and clone it and try it out.
Easiest way is:
Open Class in Intellij and press Ctrl+Shift+T
Select "Create New Test"
Now, a new pop up will be opened where you can select Unit Test Library (For your case its Junit4)
Select the methods which you want to include in test
And there you go !
Sometimes I find that this happens when I try and launch "All tests" from the project folder in the structure view. Launching all tests by right clicking on the test root folder and selecting "all tests" from there seems to solve it.
Just had this happen to me. When I built via Maven it had a problem. When I fixed the problem, it would run the junits again. Goofy.
I had the same problem, I solved it by clicking File-> Invalidate chaces and Invalidate an Restart

I have checked out a code from CVS and need to make changes to it. The code has 2 folders
Java
Test
The later has JUnit test cases. I'm not very familiar with JUnit but as far as my understanding is, the classes are duplicated in JUnit as class names. That's why I get the error in the test folder.
Class "xxxxx" already exists
I'm not sure how do I run this project without removing the folder test. Is there a way I can make eclipse ignore the JUnit test cases for now?
Go into the properties of the Eclipse project, open Java Build Path / Source and remove folder Test. Eclipse will then ignore the sources in that folder.
Test and normal java classes are merged together during build time, your error happens because the test classes have the exact same name as the normal classes. You should rename your test cases with some kind of prefix like Test to prevent them conflicting.
Doing things to work around the problem will only conflict later when you are changing the build platform, maybe your current build platform accepts it, but your future platform/editor may not, and then you have the real problems.
I have a java project in eclipse, when I press the project right click -> run as junit some tests do not run. I attached a picture, see YamiMailSenderTest for example.
When I try to run the tests directly they are running.
I am using eclipse 3.7.2.

Any idea?
Ran into the same problem, my error was that I wrote: public void myMethodName(){ //assertions }
instead of: public void testMyMethodName() { //assertions }
the test before the MyMethodName is important.
It's a bit late, but in case anyone finds this via a search engine:
If a Test is run multiple times the results provided by JUnit are indistinguishable for those Tests and thus the results are only displayed for one run. See also the following Eclipse bug report: https://bugs.eclipse.org/bugs/show_bug.cgi?id=172256
Check if you are excluding tests from run by attributes and check under Run > Run Configurations if your JUnit configuration are excluding any tests.
In jUnit 4, a test case needs to have #Test annotation. The test case can be set to ignore with #Ignore annotation. The whole test class can also be set to ignore by placing the #Ignore annotation right above the class declaration. Note: In jUnit 4 , there is no need to extend Testcase class as in jUnit 3. Everything is in annotation.
I have no idea about jUnit 3 since I use only 4.
I had a similar problem. For some reason, the "Run As -> jUnit Test" was always skiping the first test package. I was on an older version of Eclipse and SpringSource.
I moved back to Juno - Version: 4.2.1 and all my test run when I perform: "Run As -> jUnit Test. "
I had the same problem. Eclipse would only recognize and run 5 out of my 9 tests. After much troubleshooting I found this trick to convince Eclipse to recognize the remaining tests: just open each file, hit space and then backspace to mark it as changed, and save it. Then, Eclipse will recognize it as a test.
I create simple Java Application project with src and test folders. src folder consists of the class which I test and test folder consists of the class where I describe test. When I start testing, using JUnit 4 I get: Could not find the main class: org.eclipse.jdt.internal.junit.runner.RemoteTestRunner. Program will exit. error. All JAR files are presented in my project.
What did I miss in my project?
That is a class that is part of the Eclipse plugin, it sounds like you have a corrupted installation of Eclipse. Try with a fresh installation.
Far shot: is the test-folder containing the .java-files for your tests also declared as a source-folder in the project's Build Path settings?
All JUnit tests should be written as follows:
#Test //This is very very important
public void testAbc()
{
//Test Abc() here....
}
I am building an Android hello world application in Netbeans. It's building properly and I am able to run in the emulator also.
But when creating and running the Junit test I get a java.lang.NoClassDefFoundError.
How can I fix this problem?
Check the manifest of your test project, for example HelloWorldTest/AndroidManifest.xml. The android:targetPackage attribute of the instrumentation markup should target the package in your application, for example, com.example.helloworld. Not the test package of your test project (eg. com.example.helloworld.test).
Simply AndroidManifest.xml -> manifest -> package of main application should match AndroidManifest.xml -> manifest -> instrumentation -> android:targetPackage of the test application.
The full error message contains the name of the class, that wasn't found on the classpath. Double check if the classpath that is used for running the test includes all required classes and libraries (your class files, junit.jar, android specific libaries).
I find that a rebuild usually finds the classes (as it is a classpath issue). Netbeans seems to aggressively compile existing tests, but the main source code (from a maven setting at least) is not always available.
I've started running full builds to try address this. There might be a plugin that addresses this but I haven't found it yet.
EDIT: This might help.
I don't know about netbeans specifics, but the problem is probably the same.
FragmentActivity can not be tested via ActivityInstrumentationTestCase2
Your test project can be using a different android compatibility library than your main project, and that causes this weird errors.
I'm trying to run some JUnit test units in Eclipse 3.5, but with no luck at all.
JUnit3 works fine.
When I create the JUnit4 Test unit, Eclipse offers to add the JUnit library to the class-path. I accept, but when I check to see if it was added in the project's properties panel, I can see JUnit4 was added, but no JARS where included.
If I choose Edit, the combo says "JUnit 4", and just below "Current location: Not Found".
When I launch a JUnit4 test, I get an error saying and internal error occurred, NullPointerException.
I've read for about two days now, and all references say eclipse INCLUDES JUnit4, but somehow, there seems to be something I'm missing.
I've tried re-creating my projects and creating a test in brand new ones with no luck.
package test;
import static org.junit.Assert.*;
import org.junit.Test;
public class AuthServiceTest {
#Test
public final void testValidateCredentials() {
fail("Not yet implemented"); // TODO
}
}
[Edit]
I've added junit-4.8.1.jar to the project's classpath, and eclipse's classpath, but still the same problem.
[Edit2]
I also added junit-dep-4.8.1.jar, since I'm not sure if these dependencies are necessary, but no change.
Right click on the project name .
Built Path--> Add Libraries
Select the appropriate library from the list (JUnit 4 in this instance) .
In my Eclipse installation JUnit 4 is provided, it's in plugins\org.junit4_4.3.1\junit.jar
If you can't find it, then I guess that you may need to download it.
You can associate your JUnit with the Eclipse JUnit settings in
Windows->Preferences->Java->Build Path->User Libraries
Select JUnit there, and you can add and edit JARs.
It appears that the Eclipse 3.5 from Fedora's repository doesn't include JUnit, and installing the appropriate package didn't include it either.
Another Debian PC presented the same issue. A clean download from eclipse.org solved the problem.
I will report this bug at some point :)
