How do I run a specific test within junit - maven

We have several junit test cases in a particular file, how do I run a certain test alone.
Note: I am aware of the #Ignore annotation, but don't want to use it. Since you will still have to mark the rest of the use cases with the #Ignore option.

You can specify the test you would like to run via the -Dtest= parameter.
Just run it with this parameter values:
-Dtest=TestClass#singleTestCaseMethod
It is only supported in JUnit 4.x. More information: Running a single test

This depends on how you're running the tests.
If you're using Eclipse, you can either select the name of the method in the Java Editor and press F11/ctrl-F11 to Run As JUnit. This also works if the cursor is on the method name itself.
If you've already run the tests, and the JUnit view is open in Eclipse, you can rerun a particular method by right clicking on the test and selecting Run/Debug. There will be similar functionality in Intellij.
If you're running from the command line, you can use JUnitCore.
java org.junit.runner.JUnitCore TestClass1 TestClass2
EDIT: For maven, you can specify the name of the method on the command line:
mvn -Dtest=TestCircle#mytest test
See the documentation for Maven Surefire - Running a Single Test.

In IntelliJ (You should try the free community edition, I tried several IDE and I found IntelliJ to be the best, far ahead the competition), you press CtrlshiftF10 to run unit tests. The location of the cursor will decide what to run: if it's within a test, it will run this test only, if it's outside, it will run all the tests on the current class.
And shiftF10 will re-run whatever was last ran.
You can also right-click on the Run view to re-run any specific test.

How to Print logs for JUnit test results while an application in build

I am writing test cases in Junit, and when i build my application, i want to see in my logs which test cases has failed, succeeded , skipped and number of test cases run.
So how can we implement this.
When you build an application you probably run some build tool (Maven, Gradle) to do so.
Maven for example has a plugin (called surefire) for running the tests.
And it also produces a report with all the failures/ successfully run tests.
Since maven also establishes a well-known layout of directories, you'll find this report in the target/surefire-reports folder.
There are even tools that can parse the information about the tests execution and show it in a graphical way in CI tools for example

Is there test explorer in intellij idea? (to observe all the tests without execution)? I use TestNG

In VS and Resharper I could see all test in my solution before any execution, see https://www.jetbrains.com/help/resharper/Reference__Windows__Unit_Test_Explorer.html
In Idea I can't find any test explorer, only test runner but it slightly different. Maybe I need to install some dedicated plugins? I use maven and TestNG.
Project view has the special mode for Tests:
Check the documentation for details.

Running all featurefiles together in maven goal failing

I am trying to run multiple feature files through maven goal(command line) but after 2 feature files that run successfully, the other feature files (3rd one onwards) fails in some test cases which when ran independently passes all the test cases.
So f I run each feature file individually I get proper results but running them all together gives wrong results.
We are using serenity framework with cucumber jvm. Please help how can we resolve this issue.
Your failing tests fail to fully setup the context. Some state is leaking from the previous ones. Look for what has changed during the first runs (database/mocks/whatever state) that has to be reset before running the third and following.

Running Visual Studio Load Test From Build Definition

I created a build definition that runs automated tests using MTM build environments and test suites. I recently created a Visual Studio Load Test, which can be added to a test suite just like any test method marked with the [TestMethod] attribute. However, when I run the build, I get no errors and it appears the aggregate tests don't run. Is there a way to make this work?
I found this article: https://blogs.msdn.microsoft.com/testingspot/2013/01/22/how-to-automatically-run-a-load-test-as-part-of-a-build/ which describes a way to do it, but I can't find a build template that matches what he describes, and it appears this only allows you to run a single load test.
Also, when you configure a test controller, there is an option to configure it for load testing, but to do this, you must unregister it from the Team Project Collection. If this is done, it appears the controller can no longer be used in an environments to run project automated tests. This defeats the purpose of what I want to do and makes it seem that Load Tests and Team Projects are mutually exclusive. Is this the case? If so, this is a big oversight. Load tests are the kind of thing you would like to run automatically. Thanks for the help.
You are unfortunately right. A test controller used for load testing cannot be used for other automated test execution 'at the same time'. In your scenario I would recommend that you setup a different test controller and agent for load testing and you would be able to queue it as a part of your build to achieve what you are looking for.
There is no special build process template for this case.

How do i "run" a dbunity test?

I am relatively new on unity testing and just started working with dbUnit.
I wrote a test class, along with the test methods.
However, I have't figured out yet how to "run" my test case class. How can I do that? I mean, how do I execute my test methods and collect the results?
Thank you,
First of all look here: https://stackoverflow.com/a/34716990/5719185 - it is how to prepare dbUnit tests.
And you also need to mark folder with tests, but before this look here (about project structure): https://stackoverflow.com/a/28161314/5719185
After this you can choose Run in the tests class (right click in your class), or you can execute your tests with Maven, for example with clean-install.
