- When surefire plugin version &lt; 2.14: use `-DforkMode=never`
- When surefire plugin version &gt;= 2.14: use `-DforkCount=0`

In IDEA, open your run/debug configuration, in `Runner` tab, add fork options `-DforkCount=0`

I execute tests with the following options:

    mvn -Dmaven.surefire.debug=&quot;-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=6666 -Xnoagent -Djava.compiler=NONE&quot; test

... and then connect to Maven with remote debugger.


What about a right click on your goal and &quot;Debug [your goal]&quot; (in your case the test goal)?

`-DforkMode=never` doesn&#39;t work anymore, it is now deprecated in SureFire. 

Use `-DforkCount=0` instead when using surefire plugin 2.14+.

The question has been answered. But just to share my own experience. 
The selected answer did not solve my problem.
My code has multiple modules.

foolshat&#39;s reply did bring valuable insight to my problem.

I have two solutions,
1. Using your IDEA, by adding a **VM option** `-DforkMode=never`; Must run it with debug mode.
2. Set up a **remote debugging**, specifying the socket and in this case forkMode is not necessary.

It is just a summary for what I have been through.


The solution from Colin Hebert is not working to me neither. But fortunelly I found an easy way to debug the test by doing right click on the green triangle appears next to the test method:

I hope thats helps you!

I need to update 2 datetime columns, and I need them to be exactly the same, using mysql version 4.1.20. I&#39;m using this query:

    mysql&gt; update table set last_update=now(), last_monitor=now() where id=1;

It is safe or there is a chance that the columns are update with different time, because of the 2 visible calls to `now()`?  
I don&#39;t think that it can be update with different values (I think internally mysql calls `now()` just once per row or something similar), but I&#39;m not an expert, what do you think?

**Update:**
Second question was extracted [here][1].

What approach do you recommend for persisting user settings in a WPF windows (desktop) application?   Note that the idea is that the user can change their settings at run time, and then can close down the application, then when starting up the application later the application will use the current settings.  Effectively then it will appear as if the application settings do not change.  

Q1 - Database or other approach?  I do have a sqlite database that I will be using anyway hence using a table in the database would be as good as any approach?

Q2 - If Database: What database table design?  One table with columns for different data types that one might have (e.g. `string`, `long`, `DateTime` etc) OR just a table with a string for the value upon which you have to serialize and de-serialize the values?  I&#39;m thinking the first would be easier, and if there aren&#39;t many settings the overhead isn&#39;t much?   

Q3 - Could Application Settings be used for this?  If so are there any special tasks required to enable the persistence here?  Also what would happen regarding usage of the &quot;default&quot; value in the Application Settings designer in this case?  Would the default override any settings that were saved between running the application? (or would you need to NOT use the default value)

[This fabulous answer](https://stackoverflow.com/questions/717026/how-can-i-test-my-webpage-using-different-browsers/1583030#1583030) suggests there’s no way to run multiple versions of Google Chrome on one machine.

Every now and then you’ll get a website user stuck on an old version of Chrome (no idea how, but it happens — maybe they installed [the standalone version](http://googlesystem.blogspot.com/2009/03/standalone-offline-installer-for-google.html)?) with an issue, and you need to be able to verify it. Bit difficult to do that without their browser version around.

Does anyone know if there’s actually a way to do this? I.e.

1. Obtain an installer for an older version of Google Chrome (Google seems to keep very quiet about versions, which is great for users, less great for developers trying to support old versions)
2. Run two versions of Google Chrome on one machine

Can I run multiple versions of Google Chrome on the same machine? (Mac or Windows)

I need mock some class with final method using mockito. I have wrote something like this 

    @Test
    public void test() {
        B b = mock(B.class);
        doReturn(&quot;bar called&quot;).when(b).bar();   
        assertEquals(&quot;must be \&quot;overrided\&quot;&quot;, &quot;bar called&quot;, b.bar());
        //bla-bla
    }
    
    
    class B {
        public final String bar() {
            return &quot;fail&quot;;
        }
    }
But it fails. 
I tried some &quot;hack&quot; and it works.

       @Test
       public void hackTest() {
            class NewB extends B {
                public String barForTest() {
                    return bar();
                }
            }
            NewB b = mock(NewB.class);
            doReturn(&quot;bar called&quot;).when(b).barForTest();
            assertEquals(&quot;must be \&quot;overrided\&quot;&quot;, &quot;bar called&quot;, b.barForTest());
        }
It works, but &quot;smells&quot;.

So, Where is the right way?

Thanks.



Final method mocking

Reading [this question][1] has helped me solidify some of the problems I&#39;ve always had with unit-testing, TDD, et al.

Since coming across the TDD approach to development I knew that it was the right path to follow. Reading various tutorials helped me understand how to make a start, but they have always been very simplistic - not really something that one can apply to an active project. The best I&#39;ve managed is writing tests around small parts of my code - things like libraries, that are used by the main app but aren&#39;t integrated in any way. While this has been useful it equates to about 5% of the code-base. There&#39;s very little out there on how to go to the next step, to help me get some tests into the main app.

Comments such as &quot;[*Most code without unit tests is built with hard dependencies (i.e.&#39;s new&#39;s all over the place) or static methods.*][2]&quot; and &quot;[*...it&#39;s not rare to have a high level of coupling between classes, hard-to-configure objects inside your class [...] and so on.*][3]&quot; have made me realise that the next step is understanding how to de-couple code to make it testable.

What should I be looking at to help me do this? Is there a specific set of design patterns that I need to understand and start to implement which will allow easier testing?

Useful design patterns for unit testing/TDD?

I was thinking of making a new, light-weight database population framework. I absolutely hate dbunit. Before I do, I want to know if someone already did it.

Things i dislike about dbunit:

1) The simplest format to write and get started is deprecated. They want you to use formats that are bloated. Some even require xml schemas. Yeah, whatever.

2) They populate rows not in the order you write them, but in the order tables are defined in the xml file. This is really bad because you can&#39;t order your data in such a way that foreign key constraints won&#39;t cause problems. This just forces you to go through the hassle of turning them off altogether. 

This also wastes time and bloats up your junit base classes to include code to disable the foreign key constraints. You will probably have to test for the database type (hsqldb, etc.) and disable them in database-specific ways. This is way bad.

It could be better if dbunit helped in disabling foreign key constraints as part of their framework automatically, but they don&#39;t do this. They do keep track of dialects... so why not use them for this? Ultimately, all of this does is force the programmer to waste time and not get up and testing quickly.

3) XML is a pain to write. I don&#39;t need to say more about this. They also offer so many ways to do it, that I think it just complicates matters. Just offer one really solid way and be done with it.

4) When your data gets large, keeping track of the ids and their consistent/correct relationships is a royal pain. 

Also, if you don&#39;t work on a project for a month, how are you to remember that user_id 1 was an admin, user_id 2 was a business user, user_id 3 was an engineer and user_id 4 was something else? Going back to check this is wasting more time. There should be a meaningful way to retrieve it other than an arbitrary number.

5) It&#39;s slow. I&#39;ve found that unless hsqldb is used, it is painfully slow. It doesn&#39;t have to be. There are also numerous ways to mess up its configuration as it is not easy to do &quot;out of the box&quot;. There is a hump that you must go through to get it working right. All this does is encourage people to not use it, or be pissed of when they do start to use it.

6) Some values tend to repeat a lot, likes dates. It&#39;d be nice to specify defaults, or even have the framework put defaults in automatically, even without you telling it to put defaults in there. That way you can create objects just with the values you want, and leave the rest off. This sure beats specifying every nook and cranny of a column if it&#39;s not required.

7) Probably the most annoying thing is that the first entry must include ALL the values - even null placeholders - or future rows won&#39;t pick the columns that you actually specified.

DBunit doesn&#39;t have a sensible default for translating [NULL] to a real null value either. You have to manually add it. Tell me, who hasn&#39;t done this with dbunit? Everyone has. It shouldn&#39;t be like this!

What this means is that if you have a polymorphic object, you must declare all the foreign keys to the joining tables of each subclass in the first row, even though they are null. If you do a table for all subclasses pattern, you still have to specify all the fields on the first row. This is just awful.

Anything out there to satisfy me, or should I become the next framework developer of a much better database testing framework?

Is there a dbunit-like framework that doesn&#39;t suck for java/scala?

I would like to see test results ( system.out/err, log messages from components being tested ) _as they run_ in the same console I run:

And not wait until tests are done to look at the test reports ( that are only generated when tests are completed, so I can&#39;t &quot;tail -f&quot; anything while tests are running )

Where is Maven&#39;s settings.xml located on Mac OS?

I have created a minimal maven project with a single child module in eclipse helios.

In the src/test/resources folder I have put a single file &quot;install.xml&quot;. In the folder src/test/java I have created a single package with a single class that does:

      @Test
      public void doit() throws Exception {
        URL url = this.getClass().getClassLoader().getResource(&quot;install.xml&quot;);
        System.out.println(url.getPath());
    
      }

but when I run the code as a junit 4 unit test I just get a NullPointerException. This has worked fine a million of times before. Any ideas?

I have followed this guide:

http://www.fuyun.org/2009/11/how-to-read-input-files-in-maven-junit/

but still get the same error.

This is my current project structure:

    pom.xml
    /src
      /main
        /resources
          hibernate.cfg.xml
          /META-INF
            persistence.xml

I have very similar configuration params in both files (`hibernate.cfg.xml` and `persistence.xml`), which looks strange, but this is what I saw in many online examples and tutorials. I can&#39;t understand why do I need to have two files. Is it possible to work just with one? Please explain.

ps. For example, should I declare `hibernate.dialect` in both files, or just one will be enough? If so, which one to use?

what is the purpose of two config files for Hibernate?

I&#39;m switching over from Eclipse to IntelliJ. In Eclipse, if you do &lt;kbd&gt;Ctrl&lt;/kbd&gt;+&lt;kbd&gt;O&lt;/kbd&gt; in the editor, it will show a hover popup that allows you to search for a method in the class you&#39;re editing.

What is the equivalent shortcut for that in IntelliJ?

I&#39;d like to know how to setup IntelliJ to point to the JDK documentation so the documentation popups that display during code completion will show me what the function I&#39;m looking at is going to do. For some reason IntelliJ isn&#39;t able to find the JavaDocs by default.

I&#39;m also not 100% sure that the documentation is installed with the JDK that&#39;s installed with the OS. I don&#39;t see them in /System/Library/Frameworks/JavaVM.framework/ but I may be looking in the wrong place. If it&#39;s not included, I&#39;d also like to know what needs to be downloaded and where it needs to be installed to get the JavaDocs for the JDK to show up in IntelliJ.
