java - Testing for optional exception in parameterized JUnit 4+ test -

-

I am trying to write a unit test for a method that takes a string as a parameter and a Exceptions are distorted (and if it's okay then none). I want to write a parametred test that feeds in many strings and expected exceptions (in which none is thrown when input string is created well!). If @Test (expect = SomeException.class) is trying to use annotations, then I have two problems:

  1. Expected = Null is not allowed, so I How can I test for the expected outcome of an exception (for well-formed input wires)?

  2. Expected = Not possible? I have not tried this yet, but I have a strong doubt that this is the case after reading (Can you please tell that this is true?): This is the best solution I have found so far. What do you think about it, especially than that:

    Thanks for any help, I look forward to discussion :) <

    • ValidStringsTest
    • InvalidStringsTest

      / Li>

      Remember: Readability of your tests is even more important:

      Note: Already examines all valid assumptions (not an exception throwing). Do not use unique flags, terms and logic within JUnit test cases from the readability of the production code. The simplicity is the king.

      Also see my answer for a hint that how to properly test for exceptions.

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...
