void methods can be stubbed using the doThrow(), doAnswer(), doNothing(), doCallRealMethod() family of methods. Runnable mock = mock(Runnable.class); doThrow(new UnsupportedOperationException()).when(mock).run(); mock.run(); // throws the UnsupportedOperationException Note thatvoid methods...

This builds on the previous example of the Greeter class which has two dependencies, IGreetingProvider and IGreetingWriter. The actual implementation of IGreetingProvider might retrieve a string from an API call or a database. The implementation of IGreetingWriter might display the greeting in the ...

Dependency injection means writing classes so that they do not control their dependencies - instead, their dependencies are provided to them ("injected.") This is not the same thing as using a dependency injection framework (often called a "DI container", "IoC container&quo...

Add the I18N nuget package to your MVC project. In web.config, add the i18n.LocalizingModule to your <httpModules> or <modules> section. <!-- IIS 6 --> <httpModules> <add name="i18n.LocalizingModule" type="i18n.LocalizingModule, i18n" /> &...

Unnamed struct is allowed (type has no name) void foo() { struct /* No name */ { float x; float y; } point; point.x = 42; } or struct Circle { struct /* No name */ { float x; float y; } center; // but a member name float...

This is an example of how to implement custom parameter converters for JAX-RS endpoints. The example shows two classes from Java 8's java.time library. @Provider public class ParamConverters implements ParamConverterProvider { @Override public <T> ParamConverter<T> getConverter...

The @switch annotation tells the compiler that the match statement can be replaced with a single tableswitch instruction at the bytecode level. This is a minor optimization that can remove unnecessary comparisons and variable loads during runtime. The @switch annotation works only for matches again...

Most KVO and KVC functionality is already implemented by default on all NSObject subclasses. To start observing a property named firstName of an object named personObject do this in the observing class: [personObject addObserver:self forKeyPath:@"firstName" ...

Rebuilding indexes is done using the following statement ALTER INDEX All ON tableName REBUILD; This drops the index and recreates it, removing fragementation, reclaims disk space and reorders index pages. One can also reorganize an index using ALTER INDEX All ON tableName REORGANIZE; which ...

Basically you can use type inference whenever it is possible. However, be careful when combining Option Infer Off and Option Strict Off, as this can lead to undesired run-time behavior: Dim someVar = 5 someVar.GetType.ToString() '--> System.Int32 someVar = "abc" someVar.GetType.To...

From MSDN In a future version of SQL Server, ANSI_NULLS will always be ON and any applications that explicitly set the option to OFF will generate an error. Avoid using this feature in new development work, and plan to modify applications that currently use this feature. ANSI NULLS being set t...

This example shows how to get every year from this year to 2011 (2012 - 1). WITH yearsAgo ( myYear ) AS ( -- Base Case: This is where the recursion starts SELECT DATEPART(year, GETDATE()) AS myYear UNION ALL -- This MUST be UNION ALL (cannot be UNION) -- Recurs...
