This feature was added back in the upcoming Visual Studio 2012 Quarterly Update 1. Right-click the test you want to profile in the Test Explorer and select &quot;Profile Test&quot; from the context menu.

In Visual Studio it was a really powerful feature !
As you, I can not find it in VS2012 (no references in MSDN or in blogs, ...)

Now, the only solution I have found for profiling Unit Test is to Attach the Profiler to a Process called vstest.executionengine.x86.exe (x86 for me but this could be different for 64 bits)

You can do this in the Tab &quot;Performance Explorer&quot; after a right click.

![enter image description here][1]

Once the profiler is starting, you can run as many tests as you want. Then stop profiling and you will see all details of this session.

There are 2 caveats with this technique : 

 - for some reasons, the process is missing in the list. Maybe it stops when idle. Start just one test te see it.
 - You have to Attach the Profiler for every sessions. I don&#39;t find yet a way to script it.

Hope this will help you.

In Visual Studio 2015, follow the instructions Cybermaxs gives, but select `TE.ProcessHost.Managed`. Unfortunately, there appear to be two of them, so you must select the one with higher CPU usage.

I&#39;m trying to format a float as comma-separated currency.  E.g. `543921.9354` becomes `$543,921.94`.  I&#39;m using the `format` filter in Jinja templates, which seems to mimic the `%` operator in Python rather than the Python `format` function?

How can I accomplish this formatting in Jinja?  Is it possible using the `format` filter?  This is what I have so far, which accomplishes everything except the commas:

`&quot;$%.2f&quot;|format(543921.9354)`

which of course yields

`$543921.94`

I use macros extensively for ViewModel properties in [XAML][1] development. I use them even more in [WCF][2] to generate Message and DataContract properties.

To my disappointment, the macros I&#39;ve built aren&#39;t going to be usable in Visual Studio 2012.

An example of what I&#39;m talking about, for a VM, I would enter something like this.

    int id;
    string name;

Select both lines, run a macro and end up with

    private int _id;
    private string _name;

    public int Id
    {
       get {return _id;}
       set
       {
          if(_id != value)
          {
            _id = value;
            RaisePropertyChanged(&quot;Id&quot;);
          }
    }

    public string Name
    {
       if(_name != value)
       {
          _name = value;
          RaisePropertyChanged(&quot;Name&quot;);
       }
    }

I&#39;m looking for ideas of other solutions deal with losing macros.

The [assertAlmostEqual(x, y)][1] method in [Python&#39;s unit testing framework][2] tests whether `x` and `y` are approximately equal assuming they are floats.

The problem with `assertAlmostEqual()` is that it only works on floats. I&#39;m looking for a method like `assertAlmostEqual()` which works on lists of floats, sets of floats, dictionaries of floats, tuples of floats, lists of tuples of floats, sets of lists of floats, etc.

For instance, let `x = 0.1234567890`, `y = 0.1234567891`. `x` and `y` are almost equal because they agree on each and every digit except for the last one. Therefore `self.assertAlmostEqual(x, y)` is `True` because `assertAlmostEqual()` works for floats.

I&#39;m looking for a more generic `assertAlmostEquals()` which also evaluates the following calls to `True`:

 - `self.assertAlmostEqual_generic([x, x, x], [y, y, y])`.
 - `self.assertAlmostEqual_generic({1: x, 2: x, 3: x}, {1: y, 2: y, 3: y})`.
 - `self.assertAlmostEqual_generic([(x,x)], [(y,y)])`.

Is there such a method or do I have to implement it myself?

**Clarifications:**

 - `assertAlmostEquals()` has an optional parameter named `places` and the numbers are compared by computing the difference rounded to number of decimal `places`. By default `places=7`, hence `self.assertAlmostEqual(0.5, 0.4)` is False while `self.assertAlmostEqual(0.12345678, 0.12345679)` is True. My speculative `assertAlmostEqual_generic()` should have the same functionality.

 - Two lists are considered almost equal if they have almost equal numbers in exactly the same order. formally, `for i in range(n): self.assertAlmostEqual(list1[i], list2[i])`.

 - Similarly, two sets are considered almost equal if they can be converted to almost equal lists (by assigning an order to each set).

 - Similarly, two dictionaries are considered almost equal if the key set of each dictionary is almost equal to the key set of the other dictionary, and for each such almost equal key pair there&#39;s a corresponding almost equal value.

 - In general: I consider two collections almost equal if they&#39;re equal except for some corresponding floats which are just almost equal to each other. In other words, I would like to really compare objects but with a low (customized) precision when comparing floats along the way.

assertAlmostEqual in Python unit-test for collections of floats

Say I have a class with no equals() method, to which do not have the source.  I want to assert equality on two instances of that class.

I can do multiple asserts:

    assertEquals(obj1.getFieldA(), obj2.getFieldA());
    assertEquals(obj1.getFieldB(), obj2.getFieldB());
    assertEquals(obj1.getFieldC(), obj2.getFieldC());
    ...

I don&#39;t like this solution because I don&#39;t get the full equality picture if an early assert fails.

I can manually compare on my own and track the result:

    String errorStr = &quot;&quot;;
    if(!obj1.getFieldA().equals(obj2.getFieldA())) {
    	errorStr += &quot;expected: &quot; + obj1.getFieldA() + &quot;, actual: &quot; + obj2.getFieldA() + &quot;\n&quot;;
    }
    if(!obj1.getFieldB().equals(obj2.getFieldB())) {
    	errorStr += &quot;expected: &quot; + obj1.getFieldB() + &quot;, actual: &quot; + obj2.getFieldB() + &quot;\n&quot;;
    }
    ...
    assertEquals(&quot;&quot;, errorStr);

This gives me the full equality picture, but is clunky (and I haven&#39;t even accounted for possible null problems).  A third option is to use Comparator, but compareTo() will not tell me which fields failed equality.

Is there a better practice to get what I want from the object, without subclassing and overridding equals (ugh)?


How do I assert equality on two classes without an equals method?

Assume I want to unit test a method with this signature:

    List&lt;MyItem&gt; getMyItems();

Assume `MyItem` is a Pojo that has many properties, one of which is `&quot;name&quot;`, accessed via `getName()`.

All I care about verifying is that the `List&lt;MyItem&gt;`, or any `Iterable`, contains two `MyItem` instances, whose `&quot;name&quot;` properties have the values `&quot;foo&quot;` and `&quot;bar&quot;`.  If any other properties don&#39;t match, I don&#39;t really care for the purposes of this test.  If the names match, it&#39;s a successful test.

I would like it to be one-liner if possible. Here is some &quot;pseudo-syntax&quot; of the kind of thing I would like to do.  

    assert(listEntriesMatchInAnyOrder(myClass.getMyItems(), property(&quot;name&quot;), new String[]{&quot;foo&quot;, &quot;bar&quot;});

Would Hamcrest be good for this type of thing?  If so, what exactly would be the hamcrest version of my pseudo-syntax above?

I&#39;m using the Mock library to test my application, but I want to assert that some function was not called. Mock docs talk about methods like `mock.assert_called_with` and `mock.assert_called_once_with`, but I didn&#39;t find anything like `mock.assert_not_called` or something related to verify mock was **NOT called**.

I could go with something like the following, though it doesn&#39;t seem cool nor pythonic:

    def test_something:
        # some actions
        with patch(&#39;something&#39;) as my_var:
            try:
                # args are not important. func should never be called in this test
                my_var.assert_called_with(some, args)
            except AssertionError:
                pass  # this error being raised means it&#39;s ok
        # other stuff

Any ideas how to accomplish this?

I tend to write rather large templated header-only C++ libraries and my users commonly complain about compilation times. After thinking about the matter, it occurred to me that *I have no idea where the time is going*. Is there some simple way to profile the C++ compilation process with common compilers, such as g++, icc, and xlC? For instance, is it possible to get an idea of how much time is spent within [each of the phases of C++ compilation](http://www.drdobbs.com/cpp/c-compilation-speed/228701711)?

So in Java, we can do https://stackoverflow.com/questions/313893/how-to-measure-time-taken-by-a-function-to-execute

But how is it done in python? To measure the time start and end time between lines of codes?
Something that does this:

    import some_time_library
    
    starttime = some_time_library.some_module()
    code_tobe_measured() 
    endtime = some_time_library.some_module()
 
    time_taken = endtime - starttime

I&#39;ve been searching all over for a consistent and clear explanation of what &#39;self time&#39; actually refers to in the VisualVM context and how does it differ to &#39;self time (cpu)&#39;. Also does &#39;self time [%]&#39; refer to self time or self time cpu. 

There doesn&#39;t appear to be much documentation on this or at least I haven&#39;t found it. So any thoughts/input will be appreciated.

VisualVM and Self Time

I played with Visual Studio builtin profiling tools and now every time I check out any file this section automatically adds to my solution file:

    GlobalSection(Performance) = preSolution
        HasPerformanceSessions = true
    EndGlobalSection

I totally removed all profiling reports, then removed local copy of all source control files from this solution and update to latest. This section still in *.sln file after any checkout.

Other teammates who haven&#39;t used prfiler doesn&#39;t have this problem.
Has anyone any ideas?

I opened my vs2010 solution with vs2012 but it didn&#39;t make any conversion as from 2008 to 2010 was happening. So my solution still remains the same as 10 label on it. when I make a new solution of course it has 11 label on it. I haven&#39;t got any problem running like that but I am curious. Is there any difference? if yes, how to convert into vs2012 solution?

Now that macros are gone from Visual Studio 2012, what is the best way to automatically trim trailing whitespace whenever a file is saved?

I&#39;m aware that *Format Document* (&lt;kbd&gt;Ctrl&lt;/kbd&gt; + &lt;kbd&gt;K&lt;/kbd&gt;, &lt;kbd&gt;Ctrl&lt;/kbd&gt; + &lt;kbd&gt;D&lt;/kbd&gt;) will do this, but it presumably changes the file in other ways, and it&#39;s not automatic either.

The motivation is given here:
