I think you are using this function wrong. Try:

    $this-&gt;assertInstanceOf(&#39;User&#39;, $user);

It&#39;s always a good idea to use `::class` wherever you can. If you get used to this standard, you don&#39;t have to use FQCNs (fully qualified classnames), or escape backslashes. Also, IDEs provide better functionality if they know that `User` here is not just a string, but rather a class.

    $this-&gt;assertInstanceOf(User::class, $user);

Or You can use something like:

    $this-&gt;assertInstanceOf(get_class($expectedObject), $user);

I usually use this when I&#39;m checking i.e. if setter method is returning reference to self.

    $testedObj = new ObjectToTest();
    $this-&gt;assertInstanceOf(
        get_class($testedObj), 
        $testedObj-&gt;setSomething(&#39;someValue&#39;),
        &#39;Setter is not returning $this reference&#39;
    );



I have the following problem, I want to create my own colormap (red-mix-violet-mix-blue) that maps to values between -2 and +2 and want to use it to color points in my plot.
The plot should then have the colorscale to the right.&lt;br&gt;
&lt;br&gt;
That is how I create the map so far. But I am not really sure if it mixes the colors.

    cmap = matplotlib.colors.ListedColormap([&quot;red&quot;,&quot;violet&quot;,&quot;blue&quot;], name=&#39;from_list&#39;, N=None)
    m = cm.ScalarMappable(norm=norm, cmap=cmap)

&lt;br&gt;That way I map the colors to the values.&lt;br&gt;

    colors = itertools.cycle([m.to_rgba(1.22), ..])

&lt;br&gt;Then I plot it:&lt;br&gt;

    for i in range(0, len(array_dg)):
      plt.plot(array_dg[i], markers.next(),alpha=alpha[i], c=colors.next())
&lt;br&gt;
My problems are:&lt;br&gt;
1. I can&#39;t plot the color scale.&lt;br&gt;
2. I am not completely sure if my scale is creating a continues (smooth) colorscale.

I&#39;m curious as to why the backspace is necessary when setting IFS to split on newlines like this:

    IFS=$(echo -en &quot;\n\b&quot;)

Why can I not just use this (which doesn&#39;t work) instead?

    IFS=$(echo -en &quot;\n&quot;)

I&#39;m on a Linux system that is saving files with Unix line endings.  I&#39;ve converted my file with newlines to hex and it definitely only uses &quot;0a&quot; as the newline character.

I&#39;ve googled a lot and although many pages document the newline followed by backspace solution, none that I have found explain why the backspace is required.

I know that I have downloaded a `Symfony2` project and started with but I have updated my vendor several times and I want to know which version of symfony I have 

Any idea ?

How to know which version of Symfony I have?

Every now and then I see **vendor** being used in a directory structure on web apps.

Like this:

    &lt;script src=&quot;js/vendor/modernizr-2.6.2.min.js&quot;&gt;&lt;/script&gt; 

What does this mean? Why do people use it?

More importantly, should _I_ use it? I make web apps using php and javascript.

In Laravel, there appears to be a command for creating a migration, but not removing.

Create migration command:

    php artisan migrate:make create_users_table


If I want to delete the migration, can I just safely delete the corresponding migrations  file within the database/migrations folder?

I would like to add a [post to a Blogger blog][1] via PHP.
Google provided the example below. How to use that with PHP?
&gt; You can add a post for a blog by sending a POST request to the post
&gt; collection URI with a post JSON body:

    POST https://www.googleapis.com/blogger/v3/blogs/8070105920543249955/posts/
    Authorization: /* OAuth 2.0 token here */
    Content-Type: application/json
    
    {
      &quot;kind&quot;: &quot;blogger#post&quot;,
      &quot;blog&quot;: {
        &quot;id&quot;: &quot;8070105920543249955&quot;
      },
      &quot;title&quot;: &quot;A new post&quot;,
      &quot;content&quot;: &quot;With &lt;b&gt;exciting&lt;/b&gt; content...&quot;

Is it possible to create a mock object with disabled constructor and manually setted protected properties?

Here is an idiotic example:

    class A {
    	protected $p;
    	public function __construct(){
    		$this-&gt;p = 1;
    	}
    	
    	public function blah(){
    		if ($this-&gt;p == 2)
    			throw Exception();
    	}
    }
    
    class ATest extend bla_TestCase {
    	/** 
    		@expectedException Exception
    	*/
    	public function testBlahShouldThrowExceptionBy2PValue(){
    		$mockA = $this-&gt;getMockBuilder(&#39;A&#39;)
    			-&gt;disableOriginalConstructor()
    			-&gt;getMock();
    		$mockA-&gt;p=2; //this won&#39;t work because p is protected, how to inject the p value?
    		$mockA-&gt;blah();
    	}
    }

So I wanna inject the p value which is protected, so I can&#39;t. Should I define setter or IoC, or I can do this with phpunit?

phpunit - mockbuilder - set mock object internal property

I would like to be able test that a result is an integer (1,2,3...) where the function could return any number, e.g.:

    $new_id = generate_id();

I had thought it would be something like:

    $this-&gt;assertInstanceOf(&#39;int&#39;, $new_id);

But I get this error:

**Argument #1 of PHPUnit_Framework_Assert::assertInstanceOf() must be a class or interface name**


How do I assert the result is an integer in PHPUnit?

I can&#39;t seem to find an assertion in [**PHPUnit**][1] that simply tests if a string is contained somewhere in another string. Trying to do something like this:

   	public function testRecipe() {

		$plaintext = get_bread_recipe();

		$this-&gt;assertStringContains(&#39;flour&#39;, $plaintext);

	}

What real assertion would I put instead of `assertStringContains` ? I would prefer not having to worry about regex in this case because there is absolutely no need for it.

It&#39;s so simple that there must be something I have overlooked, but I just can&#39;t figure it out! Funny enough there is `assertStringStartsWith()` and `assertStringEndsWith()`!

**Update:** I know `strpos() !== false` could be used but I&#39;m looking for something cleaner. If I just use vanilla PHP functions anyway what&#39;s the whole point with all the assertions then...

How to test if string contains another string in PHPUnit?

I am struggling to run a single test method named `testSaveAndDrop` in the file `escalation/EscalationGroupTest.php` with `phpunit`. I tried the following combinations: 

    phpunit EscalationGroupTest escalation/EscalationGroupTest.php --filter=escalation/EscalationGroupTest.php::testSaveAndDrop
    phpunit EscalationGroupTest escalation/EscalationGroupTest.php --filter=EscalationGroupTest.php::testSaveAndDrop
    phpunit EscalationGroupTest escalation/EscalationGroupTest.php --filter=EscalationGroupTest::testSaveAndDrop
    phpunit EscalationGroupTest escalation/EscalationGroupTest.php --filter=testSaveAndDrop

In each case *all* test methode in the file `escalation/EscalationGroupTest.php` are executed. How to select just ONE method instead?

The name of the class is `EscalationGroupTest` and the version of `phpunit` is 3.2.8.

How to run single test method with phpunit?

I am trying to learn how to test with phpunit and laravel. When start the test using `phpunit` command, I am getting a warning :

    There was 1 failure:
    
    1) Warning
    No tests found in class &quot;PostsTest&quot;.
                                         
    FAILURES!                            
    Tests: 2, Assertions: 1, Failures: 

My test classname and filename matches. I have read other problems about unmatching names. my filename is `PostsTest.php` and my test file :


    class PostsTest extends ApiTester {
    
    	
    	public function it_fetches_posts()
    
    	{
    		$this-&gt;times(5)-&gt;makePost();
    
    		$this-&gt;getJson(&#39;api/v1/posts&#39;);
    
    		$this-&gt;assertResponseOk();
    
    	}
    
    	private function makePost($postFields=[])
    	{
    		$post = array_merge([
    			&#39;title&#39; =&gt; $this-&gt;fake-&gt;sentence,
    			&#39;content&#39; =&gt; $this-&gt;fake-&gt;paragragraph
    		], $postFields);
    
    		while($this-&gt;times --)Post::create($post);
    	}
    }
if necessary my ApiTester :

    use Faker\Factory as Faker;
    
    class ApiTester extends TestCase {
    	protected $fake;
    	protected $times = 1;
    	function __construct($faker)
    	{
    		$this-&gt;fake = Faker::create();
    	}
    }

I dont have any clue where the error is. Laravel or my local phpunit settings or anything else. Any helps is appreciated.

Thanks.

Phpunit tests gives warning no tests found in class

In a python unit test (actually Django), what is the correct `assert` statement that will tell me if my test result contains a string of my choosing?

    self.assertContainsTheString(result, {&quot;car&quot; : [&quot;toyota&quot;,&quot;honda&quot;]})

I want to make sure that my `result` contains at least the json object (or string) that I specified as the second argument above

    {&quot;car&quot; : [&quot;toyota&quot;,&quot;honda&quot;]}

I know that `static_assert` makes assertions at compile time, and `assert` - at run time, but what is the difference in practice? As far as I understand, deep down they are pieces of code, like


    if (condition == false) exit();

 - Can someone give me an example of where **only** `static_assert` will work, or **only** `assert`?
 - Do they do anything a simple `if` statement can&#39;t do?
 - Is it bad practice to use them?

How would I `assertThat` something is `null`?

for example 

     assertThat(attr.getValue(), is(&quot;&quot;));

But I get an error saying that I cannot have `null` in `is(null)`.

My lecturer has asked me that in class, and I was wondering why is it a macro instead of a function? 

Why is assert a macro and not a function?

Is there any reason to group multiple assertions:

    public void shouldTellIfPrime(){
        Assertions.assertAll(
                () -&gt; assertTrue(isPrime(2)),
                () -&gt; assertFalse(isPrime(4))
        );
    }

instead of doing this:

    public void shouldTellIfPrime(){
        Assertions.assertTrue(isPrime(2));
        Assertions.assertFalse(isPrime(4));
    }

assertAll vs multiple assertions in JUnit5

**Context**

in XUnit github I found this: [Add Assert.Equal(expected, actual, message) overload #350][1] *(so a developer ask for a non existing overload see below)*

Quote from the answer:

&gt; We are a believer in self-documenting code; that includes your assertions.

*(so the XUnit team rejects it)*

  [1]: https://github.com/xunit/xunit/issues/350

OK, I got it. I also believe the self documenting code. Still I can not find out 
this use case:

**Sample**

    // Arrange
    // Create some external soap service client and its wrapper classes
    
    // Act
    // client.SomeMethod();

    // Assert
    // Sorry, soap service&#39;s interface, behaviour and design is *given*
    // So I have to check if there is no Error, and 
    // conveniently if there is, then I would like to see it in the assertion message

    Assert.Equal(0, client.ErrorMessage.Length); // Means no error

    // I would like to have the same result what would be the following *N*U*n*i*t* assert:
    // Assert.AreEqual(0, client.ErrorMessage.Length, client.ErrorMessage); // Means no error

**Question**

How can I implement a descriptive assert message in this case in XUnit which still has no such an overload?
