I'm having difficulty using the required annotation of June 4 to see exceptions. I can not compile the code because it has an unrestricted exception

This is a simple example that creates a situation: 

  import static org.junit.Assert. *; Import java.io.UnsupportedEncodingException; Import org.junit.Test; Public class simple {@ test (expected = unsupported encoding exception. Clash) Public Zero Simple () {string A = ""; A.getBytes ("UTF-123"); }}   
 I get a compilation error called "compiled exception type unsupported encoding exception"  
 It makes sense, and I can make it clear that Simplified unsupported encoding throws an exception, we have seen many examples online where people do not do it (which would be good when writing a lot of test cases).  
 Is there a way to configure the test case, which clearly tell me what exceptions will be thrown?   
 
 
 As far as I know, unsupported encoding exceptions are a check exception, therefore the compiler expects That throws the section for a checked exception. I think your code will work, if you say that you have tried an arbitrary exception such as arithmetic exception.

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
