I've been following along a couple of tutorials and at the point where they run the tests in the junit test view in Eclipse, mine just looks disabled, and I can see any tests to run:
Notice on the right hand side I have an empty JUnit view. None of the tutorials mention anything about this situation. You can see the JUnit library in my Package Explorer too. What do I need to do now to get my test to run in the JUnit test view?
You got the project setup right, now you need to tell eclipse to execute the test cases locate in the project, for that you need to do the following
Right click project --> run as --> Junit Test
And the Junit view of the eclipse will get populated with the test runs as below with the results of which cases failed and which passed
Just right click on AssertTest.java; then follow below--
run as > Junit Test
Since looking into your screen shot, you only have one Junit class; so it seems this will help you to run Junit.
I found this post while looking into a slightly different "empty JUnit view" issue: after upgrading to Eclipse 2022.06 from 2021.??, my JUnit view stopped working. I could see the unit tests running in the console, but no results were shown in the view.
I was able to fix it by opening the Eclipse preferences Java -> JUnit, then clicking Apply and Close.

I have a Java project on VSCode for Windows and I have installed the Test Runner plugin ...
I would like to be able to run a test file from the editor and see the results. In Eclipse, I can right click on the test file but when I open the test file in the editor
I don't see any option to right click and run my test file and I don't see any "Run Test" text hovering above my test file class, as some other posts seem to suggest. What is the right way to run a test from the editor? I'm not tied to Test Runner for Java. I'm open to using other extensions.
The Test Runner for Java extension supports the following test frameworks:
JUnit 4 (v4.8.0+)
JUnit 5 (v5.1.0+)
TestNG (v6.9.13.3+)
You must first enable testing and adding test framework JARs to your project. Then in the Testing panel on the left, you can see the test list of the project and test it. A Test button is also displayed to the left of the test script.
There are more details you can look at this document.
I found similar questions but no satisfactory answers. In addition, most answers were rather old as well, so I wonder if the combination eclipse / Junit got better in the meantime.
Instead of packing projects into test suites, I would like to spread tests cases all over the place in the package structure (I'm programming in Java). Then right clicking on whatever package (on the package explorer) should bring the option Run As -> JUnit Test and run all the unit tests in that package and below (recursively). In this way, I wouldn't have to care about maintaining the test structure, it would be in the packages themselves.
I've seen that this works only with end packages (with no children), but not recursively. Do you have any ideas? I'm using eclipse Kepler (4.3.0), JUnit 4 and Java 1.6.
Why cant you create a run config in eclipse to run all the JUnit tests ?
Refer the screen shot.
Select the radio button which says
Run All tests in the selected project, package or source folder.
Getting back into Java coding after being away for a while, downloaded the latest Maven (3.1.1), the latest Eclipse (Kepler), the latest JDK (1.7.0_45), created a new Maven project in Eclipse (using the quickstart archetype, which looks like it defaulted to JUnit 3.8.1), opened AppTest.java, selected "Run As JUnit Test" (not JUnit Plug-in Test), and nothing shows up in the JUnit view.
Shouldn't it at least say something like "Runs: 1/1"? If I change the code in testApp() to "assertTrue( false)", then I don't see a failure (although if I debug, sure enough, an exception gets thrown). If I put a println() in the test, I see its output in the console view. If I run mvn test from the command line, I get a lovely stacktrace and the word "FAILURE!" (and my println() output).
So. Something basic is wrong somewhere, but what?
Maybe you checked the "Show Failures Only" option? (on the same bar as "Rerun Test"). It happened to me :)
I think I repeat your problem. It happens when the JUnit window is opened initially in eclipse (for example I detached the view as separate window and it shows when eclipse starts).
With fresh start (window/view shown) I run tests and don't see anything in it, when I close it and run unit tests (via 'run as') window reopens but now results are shown.
In my attempt to implement a JUnit test suit through Ant, I stumbled across the question of whether it'd be possible to make the suite results show up in the typical Eclipse JUnit window, when run from Eclipse.
Is it possible?
Thanks
You may use Right-Click -> Open With -> JUnit View on the XML result file to achieve this.
First time I am trying Junit and I am following below link:
http://www.vogella.de/articles/JUnit/article.html
When I run my testClass as Run-As-> Junit Test. It says below thing.
Please help me in figure it out.
Could not launch the JUnit plug-in tests because project 'SalesTax'
is not a plug-in project.
SalesTax: Is the Project Name
I suspect you did create an Eclipse 'jUnit Plugin Test' launch configuration which is designed to run Eclipse plugins jUnit tests (in some kind of mocked eclipse environment).
Try to create a simple 'jUnit' launch configuration instead.
Suggestion - Follow the tutorial. type in the (3-line) example "MyClassTest" from the tutorial. Verify that you can get the tutorial working. Post back with any questions about the tutorial.
Once you get one complete example working, end-to-end (your code, your JUnit test code, and successfully building and executing at least one JUnit test in your IDE), then try to get your "SalesTax" project working.
Q: I presume you're using Eclipse, correct? Eclipse 3.7?
PS:
Here's another good tutorial:
