c# - How to use Moq to test a method with no return value? -

-

This is my first question, please be kind! :)

What I am trying to do is write a test for a manager class that during the construction many new examples of single item class are added in the list. When UpdateAllItems is called in this manager category, it is intended to iterate the intent list and make an incremental call to each individual item.

The manager class is my code, but the single item class is not the same, so I can not modify it.

I use NUnit for a test framework and I'm starting to work. . Because the manager class uses the single item class, I think I'll need to use a Moq, so I'm just testing the manager, not a single item.

How do I test a test for my UpdateAllItems method? (Technically I should know the first test).

Here is some sample code that gives me the general idea of ​​working with it ... 

  public class single-id codecuntbofified {public int-current value {received ; Private set; } Public Single Entity Discounted Entitlement {CurrentValue = startValue; } Public Zero Enhance () {CurrentValue ++; }} Public Class Single Entrepreneur Manager {list & lt; Single IT CodecounterBmAffaed & gt; Item = new list & lt; Single item_codentbmodified & gt; (); Public SingleItemem Manager () {items.Add (new single item codecannedbymified (100)); item. Add (New SingleItem_CoderentBoamed (200)); } Public Zero UpdateAllItems () {items.ForEach (item => item.Increment ()); }}   
 Thanks in advance for all help!   
 
 
 The simple answer is, you can not  UpdateAllItems  call ( Increment () ) method is non-virtual, so you will not be able to fake it.  
 Your options, as I see, are:  
     
  •   UpdateAllItems  do not check at all. Its implementation is trivial, so it is an option to consider (though not ideal).  
  •  Make a real  SingleItem_CodeCantBeModified  example in your test Purists will say that you do not have the  unit  exam at this point, but this is still a useful test Could.  
  •  Add a  ISingleItem  interface, and a  single itam adapter: icinglight code  class which is in the context of  SingleItem_CodeCantBeModified  and calls Then you can work on  ISingleItem  s by typing  single item manager , and you pass in your tests in the fake  ISingleItem  s To be free (depending on how your system is set up, you can descend from  SingleItem_CodeCantBeModified , Applying the interface to your offspring, and instead of writing an adapter, you can use those items.)   
     This last option gives you the most options, but some of the complexity at cost. Choose the option you are trying to complete.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered.

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
